ID of the asset

any url-encoded or alphanumeric, non-whitespace set of characters. may contain hyphens and dots

Specifies the width of the output image in pixels. This parameter allows you to control the horizontal dimension of either the final output image or a specific layer. The width must be a positive integer (minimum value: 1).

When used in combination with the height parameter, the aspect ratio of the original image is preserved. This means the actual output width may be smaller than the requested value to preserve aspect ratio.

If not defined, the image width defaults to a maximum of 2048 pixels.

Examples without layer:

• width=200 - Set width of final output image to 200 pixels

Examples when used with a layer named layerName:

• width[layerName]=200 - Set width of specific layer to 200 pixels

Only one of width or width[layerName] should be used at a time.

Specifies the compression quality for the image. Quality value ranges from 1 to 100, where 100 is the highest quality (least compression) and 1 is the lowest quality (highest compression).

A higher quality value results in better image quality but larger file size, while a lower value reduces file size at the cost of image quality.

Note: For dynamic quality based on network conditions, use max-quality instead of quality.

Example:

• quality=85 - Set quality of final output image to 85

Only the global quality parameter is supported.

Specifies the maximum quality for the image when delivery-engine dynamically adjusts the quality of the image based on the client's network bandwidth. The value ranges from 1 to 100, where 100 is the highest quality (least compression) and 1 is the lowest quality (highest compression).

By default, the value is set to 85 and network-based dynamic quality adjustment is enabled.

Unlike the static quality parameter, max-quality acts as an upper bound. The actual quality used for image delivery may be reduced below this value depending on the round-trip time (RTT) and network conditions of the requester. This helps optimize image delivery for faster loading on slower networks by reducing file size when needed.

Note: If quality is specified, max-quality is ignored.

Example:

• max-quality=85 - Set the maximum quality to 85; actual delivered quality may be lower based on network speed

max-quality parameter is only applied at final output image.

Applies intelligent cropping to automatically identify and preserve visually most important areas of the image for a given crop-region. This operation uses AI-powered content-aware cropping to ensure that key elements like faces, text, or focal points are retained in the output.

The smartcrop parameter expects that named-smartcrop-profiles exist and have been applied to the asset. Those predefined profile names - specifying the target dimensions and aspect ratio of the cropped image - can be supplied as values of this parameter. The cropping can be applied either to a specific layer or to the final output image.

Examples without layer:

• smartcrop=QHD - Apply a smartcrop profile named QHD to final output image

Examples when used with a layer named layerName:

• smartcrop[layerName]=QHD - Apply a smartcrop profile named QHD to a specific layer

Only one of smartcrop or smartcrop[layerName] should be used at a time.

NOTE: Specifying an unresolvable smartcrop profile-name (the one that hasn't been defined, or hasn't been applied to the asset being requested) will lead to an error response.

Device Pixel Ratio (DPR) (also known as CSS pixel ratio) is the relation between a device's physical pixels and logical pixels.

Enabling Device Pixel Ratio optimization with HTML5 Responsive Imaging techniques renders the image at the native resolution of the screen which makes it sharp. For more information about DPR and how it affects image resolution, see MDN Documentation for devicePixelRation property of browser-window object.

Examples without layerName:

• dpr=2 - Renders the final output image at twice the requested dimensions to support high-DPI displays

Examples when used with a layer named layerName:

• dpr[layerName]=2 - Renders a specific layer at twice the requested dimensions to support high-DPI displays

Specifies the height of the image or a specific layer in pixels. When applied to the final output image or a layer, the image is scaled to match the specified height while maintaining the aspect ratio.

The value must be a positive integer (minimum: 1 pixel).

NOTE: If not defined, the height is automatically scaled to maintain aspect ratio based on the width (specified, or default). If defined alongside width, the dimensions of the output (or the layer) layer image are computed by applying fit=contain (see more here).

Examples without layer:

• height=200 - Set height of final output image to 200 pixels

Examples when used with a layer named layerName:

• height[layerName]=200 - Set height of specific layer to 200 pixels

Only one of height or height[layerName] should be used at a time.

Applies a sharpening filter to enhance the edges and details in the image. The sharpening is applied either to a specific layer or to the final output image after all scaling operations are complete.

When enabled, this operation increases the contrast between adjacent pixels to make the image appear more crisp and detailed.

Examples without layerName:

• sharpen=true - Apply sharpening to the final output image

Examples when used with a layer named layerName:

• sharpen[layerName]=true - Apply sharpening to a specific layer

Only one of sharpen or sharpen[layerName] should be used at a time.

Applies a blur filter to soften the image. The blur can be applied either to a specific layer (when layerName is provided) or to the final output image (when no layerName is specified). The radius parameter determines the strength of the blur effect in pixels relative to the final output image, with a value between 0 and 100 pixels.

Examples without layerName:

• blur=5 - Apply a blur filter to the final output image with a radius of 5 pixels

Examples when used with a layer named layerName:

• blur[layerName]=5 - Apply a blur filter to a specific layer with a radius of 5 pixels

Crop is specified by four comma-separated values, each a number with up to two digits after the decimal point, followed by p.

First two specify the origin (top, left) of the desired cropped region as percentages of width and height of the original image, respectively.

Last two specify the size of the cropped region relative to original dimensions of the asset.

A valid crop region MUST meet both of the following constraints:

• <x-origin> + <crop-region-width> <= 100
• <y-origin> + <crop-region-height> <=100

Requests which don't meet aforementioned constraints will fail.

Examples:

• crop=10p,10p,50p,50p - Crop the final output image starting at 10% from top and left, taking 50% of width and height of the final output image
• crop[layerName]=10p,10p,50p,50p - Crop a specific layer starting at 10% from top and left, taking 50% of width and height of the final output image

Image Preset represents a predefined collection of sizing and formatting modifiers for output image. Image Preset is a feature provided in AEM Assets. Post generation of a preset, it can be applied to the output image by specifying the preset name in this modifier.

To generate a preset, please refer to the documentation here.

Examples without layer:

• preset=preset-name

Examples when used with a layer named layerName:

• preset[layerName]=preset-name

Layers allow composition of a single output image from multiple segregations, each of which may have specific operations applied to them. Search for layerName in the documentation to identify the parameters that can be applied to layers.

The layers which segregate the operations (and are finally aggregated to compose the single output image) are addressed by the names in the value of this parameter. These names are then used in rest of the parameters (which can be applied to layers) in the URL. The names are to be separated by the | character, and need to appear in the order in which they are painted when aggregated to produce the output image (rightmost layer specified in this parameter is painted the last when composing the aggregate.

Layer names are case-sensitive and can have any alphanumeric characters (a-z, A-Z, 0-9).

NOTE: base is reserved for the "base" layer - the lowermost layer (even if specified in the layers parameter at any other position) and will always be included (even if omitted from the layers parameter). i.e., layers=base|mid|top, layers=mid|top and layers=mid|base|top are all equivalent, and the recommendation is to follow either the first or the second pattern.

NOTE: Nested layers are not supported, and the layers parameter can not applied to any other layer. e.g., layers=top&layers[top]=top1|top2 is invalid.

Specifies the resizing behavior when fitting the image within the output dimensions specified with width or height.

In the following description of the mode options, it is assumed that

• xScale is the ratio of the original image width to the output image width, and
• yScale is the ratio of the original image height to the output image height.

It takes the following values:

The color and transparency of the whitespace fill is determined by background-color and transparency.

Examples without layer:

• fit=contain

Examples when used with a layer named layerName:

• fit[layerName]=contain

NOTE: Attempting to apply fit without requesting atleast one of width or height (explicitly, or implicitly) will result in an error.

Specifies the background color for the transparent areas of the image or selected layer.

This operation takes following parameter values:

Defaults to fully transparent.

Examples without layer name:

• background-color=gray,7F - Gray color
• background-color=graya,7FFF - Gray color with alpha
• background-color=rgb,808080 - RGB color
• background-color=rgba,32808080 - RGB color with alpha

Examples with layer name:

• background-color[layerName]=gray,7F - Gray color for specific layer
• background-color[layerName]=graya,7FFF - Gray color with alpha for specific layer
• background-color[layerName]=rgb,808080 - RGB color for specific layer
• background-color[layerName]=rgba,32808080 - RGB color with alpha for specific layer

Specifies the foreground color for the image or selected layer.

This operation takes following parameter values:

• foreground-color=gray,7F - Gray color
• foreground-color=graya,7FFF - Gray color with alpha
• foreground-color=rgb,808080 - RGB color
• foreground-color=rgba,32808080 - RGB color with alpha

Examples with layer name:

• foreground-color[layerName]=gray,7F - Gray color for specific layer
• foreground-color[layerName]=graya,7FFF - Gray color with alpha for specific layer
• foreground-color[layerName]=rgb,808080 - RGB color for specific layer
• foreground-color[layerName]=rgba,32808080 - RGB color with alpha for specific layer

Controls the behaviour of browser format conversion for Smart Imaging capabilities. When auto-format is true, the requested format is ignored and a web-optimized format based on image-characteristics, browser capabilities, and license-entitlement is selected automatically.

The default value is true, which enables automatic format conversion. This can be disabled by specifying auto-format as false, in which case the requested output-format will be returned.

For example,

• When true, an avif output is delivered (if the browser supports avif and the license-entitlements allow it), even when the requested format is jpeg.
• When true, a webp output is delivered if the browser doesn't support avif, but does support webp, even when the requested format is jpeg.
• When true, a jpeg output is delivered if the browser doesn't support avif or webp and the image doesn't have an alpha channel (transparency), even when the requested format is avif.
• When false, a jpeg output is delivered (irrespective of the browser capabilities and license-entitlements) when the requested format is jpeg.

Examples:

• auto-format=true - Enable browser format conversion (default)
• auto-format=false - Disable browser format conversion

Applies an Unsharp Masking filter on the output image to produce a sharpening effect. The effect can be tuned for intensity, radius (measured in pixels), and a threshold of contrast (beyond which the effect is ignored). This modifier uses the same options as Photoshop's "Unsharp Mask" filter.

This operation accepts following parameters in the value:

Examples without layer:

• unsharp-mask=100,10 - apply basic unsharp mask operation to the output image
• unsharp-mask=100,10 - apply basic unsharp mask operation to the output image
• unsharp-mask=100,10,10,true - apply the unsharp unsharp mask operation to the output image

Examples when used with a layer named layerName:

• unsharp-mask[layerName]=100,10 - apply basic unsharp mask operation to the layer
• unsharp-mask[layerName]=100,10 - apply basic unsharp mask operation to the layer
• unsharp-mask[layerName]=100,10,10,true - apply the unsharp unsharp mask operation to brightness component of the image

Setting this parameter to true forces "download" prompt in browser by adapting the Content-Disposition appropriately.

Default is false.

Flips (mirrors) the image or a specific layer horizontally, vertically, or both. This operation is useful for adjusting the orientation of content within layers.

Supported values:

• h - Horizontal flip (left-to-right mirror)
• v - Vertical flip (top-to-bottom mirror)
• hv - Both horizontal and vertical flip

Examples without layer:

• flip=h - Flip the final output image horizontally
• flip=v - Flip the final output image vertically
• flip=hv - Flip the final output image both horizontally and vertically

Examples when used with a layer named layerName:

• flip[layerName]=h - Flip a specific layer horizontally
• flip[layerName]=v - Flip a specific layer vertically
• flip[layerName]=hv - Flip a specific layer both horizontally and vertically

Only one of flip or flip[layerName] should be used at a time.

Rotates the image or a specific layer by a fixed angle in clockwise direction. The rotation is performed around the center point of the image or layer.

Rotation angle must be a multiple of 90 degrees and can be either of '90', '180', or '270' degrees clockwise.

Examples without layer:

• rotate=90 - Rotate final output image 90 degrees clockwise
• rotate=180 - Rotate final output image 180 degrees
• rotate=270 - Rotate final output image 270 degrees clockwise

Examples when used with a layer named layerName:

• rotate[layerName]=90 - Rotate specific layer 90 degrees clockwise
• rotate[layerName]=180 - Rotate specific layer 180 degrees
• rotate[layerName]=270 - Rotate specific layer 270 degrees clockwise

Only one of rotate or rotate[layerName] should be used at a time.

Specifies the fallback image to be used when the requested image cannot be found. This is useful for substituting missing images with default images.

If the original image does not exist and no fallback is specified, an error is returned.

Important: If the fallback image itself does not exist, an error is returned.

Examples without layer:

• fallback=urn:aaid:aem:1a034bee-ebda-4787-bad3-f924d0772b75 - Use a specific image as fallback when the requested image is not found

NOTE: When a fallback image is used, it replaces the missing image while maintaining the original request's attributes for the layer.

Adds additional pixels around a layer (e.g., adding a border) or makes the layer smaller by clipping-off pixels. The extend operation is applied to the output image or layer after other modifiers have been applied.

The default value is 0,0,0,0, which means no change to the layer rectangle.

The extended area is filled with background-color, or if not specified, remains transparent.

Can be specified as:

• Four comma-separated values specifying the number of pixels to add to (positive values) or remove from (negative values) the left, top, right, and bottom edge of the layer rectangle
• Four comma-separated values followed by 'p' for relative (percent) dimensions relative to the original layer rectangle size

Examples without layer:

• extend=5,5,5,5 - Add 5 pixels margin to all sides
• extend=0,30,0,0 - Add 30 pixels margin to top only
• extend=-10,-10,-10,-10 - Cut off 10 pixels from all sides
• extend=10p,10p,10p,10p - Add 10% margin to all sides (relative)

Examples when used with a layer named layerName:

• extend[layerName]=5,5,5,5 - Add 5 pixels margin to specific layer on all sides
• extend[layerName]=10,0,10,0 - Add 10 pixels margin to left and right of specific layer
• extend[layerName]=-5,0,-5,0 - Cut off 5 pixels from left and right of specific layer
• extend[layerName]=20p,30p,80p,90p - Apply relative margins to specific layer

Specifies one or more clipping paths to be applied to the base layer (learn more about base layer here) or the selected layer, with optional inversion.

A clipping path is a vector path or shape used to isolate a portion of an image. Some image formats (such as TIFFs, PSDs, etc.) can embed clipping paths within the image-binary and identify them by names (ASCII strings). This modifier allows selection of named clipping paths as embedded in the image and applies them to the specified layer.

Normal vs Inverted Clipping:

• Normal clipping: Any parts of the layer that fall outside the area defined by the clipping path are rendered transparent
• Inverted clipping: Any parts of the layer that fall within the area defined by the clipping path are rendered transparent (prefix path name with ~)

More than one clipping path name (separated by ,) can be specified. When multiple clipping paths are specified, each path is processed with its specified behavior (normal or inverted), and the results are combined to determine the final clipping effect on the layer.

Any clipping path names not found in the image are ignored when generating final output. If the intersection of selected clipping paths is an empty path, then the complete modifier is ignored.

Examples:

• clip-path-names=path1 - Apply normal clipping with path "path1" on the base layer
• clip-path-names=~path1 - Apply inverted clipping with path "path1" (makes area inside path transparent) on the base layer
• clip-path-names[layerName]=path1,~path2,path3 - Apply normal clipping for "path1" and "path3", inverted clipping for "path2"
• clip-path-names[layerName]=~path1,~path2 - Apply inverted clipping for intersection of "path1" and "path2"

Allows increasing or decreasing the transparency of the output image.

Examples without layer:

• transparency=50 - Set the transparency to 50%

Examples when used with a layer named layerName:

• transparency[layerName]=50 - Set the transparency of specific layer to 50%

Controls the visibility of a layer without modifying the request URL structure. This is useful for:

• Conditional content delivery - Show/hide layers based on user preferences, device capabilities, etc.
• Preset-based workflows - Use a single URL template with multiple layers and programmatically control which layers are visible

Examples:

• hide-layer[layerName]=false - The layer will be rendered normally (this is the default behaviour when hide-layer[layerName]modifier isn't specified)
• hide-layer[layerName]=true - Hide the specified layer if previously defined (layer will not be rendered). Specifying a layerName that doesn't exist makes this modifier a no-op.

Inverts each color component for a negative image effect.

Examples without layer:

• invert-color=true - Invert the colors of the final output image.

Examples when used with a layer named layerName:

• invert-color[layerName]=true - Invert the colors of the layer.

Colorizes the image data while preserving shadows and highlights.

Colorize accepts the following parameter values:

The second parameter specifies whether the brightness of the source image should be adjusted before colorizing. Specify noautobrightness to disable the automatic brightness compensation or autobrightness to adjust the brightness automatically so that the median value is at 50% intensity.

Set the contrast value to 0 to preserve the contrast range of the input image, or specify a desired contrast range with a value greater than 0. A value of 100 maximizes the contrast. Typical values might be between 30 and 70.

The colorizing algorithm uses only the luminance information in the image data. This conversion to grayscale is simple and not color-managed. colorize always outputs RGB data, even if the input is grayscale or CMYK

Properties:

• The contrast value is ignored if brightness compensation is turned off.
• The color-value specified in RGB color parameter is automatically converted to as appropriate to source image's or layer's pixel type before application.
• CMYK images are converted to RGB before the operation is applied.

Colorization is disabled by default.

Examples without layer:

• colorize=a0b0c0,autobrightness,50 - Colorize the image with a blue tint.

Examples when used with a layer named layerName:

• colorize[layerName]=a0b0c0,autobrightness,50 - Colorize the layer with a blue tint.

Decreases or increases the image brightness. The adjustment range is from -100 to +100, where -100 is the darkest and +100 is the brightest.

The default value is 0, which means no change in brightness.

Examples without layer:

• brightness=10 - Increase brightness by 10 units
• brightness=-10 - Decrease brightness by 10 units

Examples when used with a layer named layerName:

• brightness[layerName]=10 - Increase brightness of specific layer by 10 units
• brightness[layerName]=-10 - Decrease brightness of specific layer by 10 units

Only one of brightness or brightness[layerName] should be used at a time.

Adjusts the image contrast by increasing the brightness of pixels with more than 50% brightness, and reducing the brightness of pixels with less than 50% brightness. The adjustment range is from -100 to +100, where -100 provides the lowest contrast and +100 provides the highest contrast.

The default value is 0, which means no change in contrast.

Examples without layer:

• contrast=50 - Increase contrast by 50 units
• contrast=-12 - Decrease contrast by 12 units

Examples when used with a layer named layerName:

• contrast[layerName]=50 - Increase contrast of specific layer by 50 units
• contrast[layerName]=-12 - Decrease contrast of specific layer by 12 units

Only one of contrast or contrast[layerName] should be used at a time.

Specifies how certain operations will behave if the image has a mask. This modifier allows specifying whether the operations that take mask into consideration are applied within the masked region (normal) or outside (inverted).

Following modifiers can alter their output when applied alongside mask:

• colorize
• hue
• saturation
• brightness
• contrast
• blur
• sharpen
• noise
• invert-color

If no value is provided, mask modifier is off.

The following table illustrates the effect depending on availability and type of the mask (alpha channel) associated with the source image:

Mask Types:

• Unassociated mask (straight alpha): RGB values are stored independently of transparency. Full color information is retained regardless of transparency level.
• Associated mask (pre-multiplied alpha): RGB values are multiplied by alpha. Fully transparent areas lose their original color data.

Examples without layer:

• mask=normal - Apply normal mask behavior
• mask=inverted - Invert the mask to affect background area

Examples when used with a layer named layerName:

• mask[layerName]=normal - Apply normal mask behavior to specific layer
• mask[layerName]=inverted - Invert mask for specific layer to colorize background

Only one of mask or mask[layerName] should be used at a time.

Changes the saturation of each visible pixel of the layer or output image. This allows for adjusting the color intensity of the image.

The saturation value can be an integer between -100 and +100:

• Positive values increase color saturation
• Negative values decrease color saturation
• -100 fully desaturates the image (converts to grayscale)
• 0 leaves the saturation unchanged

Examples without layer:

• saturation=50 - Increase saturation of the output image by 50%
• saturation=-60 - Decrease saturation of the output image by 60%
• saturation=45 - Increase saturation for a high-key appearance
• saturation=-35 - Decrease saturation for a more muted look
• saturation=0 - Keep original saturation (no change)

Examples when used with a layer named layerName:

• saturation[layerName]=50 - Increase saturation of the specified layer by 50%
• saturation[layerName]=-100 - Fully desaturate the specified layer (convert to grayscale)

Shifts the hue of each visible pixel of the layer or output image by the specified amount.

It takes value adjustment in degrees (-180…+180 int).

Properties: Applies to the current layer or to the output image. CMYK images or layers are converted to RGB before the operation is applied.

Examples without layer:

• hue=50

Examples when used with a layer named layerName:

• hue[layerName]=50

Adds random noise to the foreground image data.

Default value is 0 (no noise applied).

This operation takes following parameter values:

Examples without layer:

• noise=10 - Add 10% uniform noise to the image
• noise=10,gaussian - Add 10% gaussian noise to the image
• noise=10,uniform,true - Add 10% monochrome uniform noise to the image

Examples when used with a layer named layerName:

• noise[layerName]=10 - Add 10% uniform noise to the specified layer
• noise[layerName]=10,gaussian - Add 10% gaussian noise to the specified layer
• noise[layerName]=10,uniform,true - Add 10% monochrome uniform noise to the specified layer

Note: The monochrome parameter has no effect for grayscale outputs since color noise is not possible to add.

Specifies the type of blending when there are multiple layers. Simulates commonly used blending modes available in Photoshop.

Value can be one of

• dissolve
• lighten
• darken
• multiply
• screen

Examples:

• blending-mode[layerName]=multiply - Apply multiply blending mode to specific layer
• blending-mode[layerName]=lighten - Apply lighten blending mode to specific layer
• blending-mode[layerName]=screen - Apply screen blending mode to specific layer

Applies morphological erosion operation to pixels in the image. The value is in pixels relative to the output image.

This modifier performs an erosion (contraction) of the features in the image. See dilate modifier for a dilation (expansion) of image features.

NOTE: Specifying erode and dilate at the same time for a given source or layer isn't supported and can result in undefined behaviour. Examples without layer:

• erode=3 - Contract image features by 3 pixels
• erode=10 - Contract image features by 10 pixels Examples when used with a layer named layerName:
• erode[layerName]=5 - Contract features in specific layer by 5 pixels
• erode[layerName]=8 - Contract features in specific layer by 8 pixels

Applies morphological dilation operation to pixels in the image. The value is in pixels relative to the output image.

This modifier performs a dilation (expansion) of the features in the image. See erode modifier for an erosion (contraction) of image features.

NOTE: Specifying dilate and erode at the same time for a given source or layer isn't supported and can result in undefined behaviour.

Examples without layer:

• dilate=3 - Expand image features by 3 pixels
• dilate=10 - Expand image features by 10 pixels Examples when used with a layer named layerName:
• dilate[layerName]=5 - Expand features in specific layer by 5 pixels
• dilate[layerName]=8 - Expand features in specific layer by 8 pixels

Specifies the position of the center of a given layer relative to center of the base layer.

The base layer is the asset specified by {assetId} in the API path /adobe/assets/{assetId}/as/seoname.<extn> - this is the primary layer onto which all other layers are positioned.

Can be specified as pixel offset or normalized offset from this layer's center to the base layer's center.

Can be specified as:

• Pixel offset from this layer's center to the base layer's center
• Normalized offset from this layer's center to the base layer's center using 'p' suffix (relative coordinates)

Positive values move the layer towards the right/bottom, and negative towards the left/top. With relative coordinates, 50p,50p moves the layer by half the base layer width and height down and right.

Examples:

• position[layerName]=100,100 - Position layer 100 pixels right and down from base layer
• position[layerName]=50p,50p - Position layer by half the base layer width and height down and right
• position[layerName]=-50,25 - Position layer 50 pixels left and 25 pixels down from base layer
• position[layerName]=0p,0p - Position layer center at same location as base layer center (default)

Specifies the assetId to be used as the source for a specific layer. The layer name is case-sensitive.

Can only be used with a layer.

Examples:

• source[background]=urn:aaid:aem:1a034bee-ebda-4787-bad3-f924d0772b75 - Set the source for layer "background" to the specified assetId for this layers=background should exist in the query parameters

NOTE: This can be only used with layers modifier.

Crop to the bounding box of one or more embedded named paths in the source image. This cropping, in turn, changes the size of the image.

Key features:

• (only) ASCII path names are supported
• Intersection operation: When multiple crop names are specified, the image is cropped to the intersection of all specified path bounding boxes simultaneously
• The operation changes the actual size of the image

Examples:

• crop-names=border-with-curved-corners - Crop the final output image to the bounding box of the path named "border-with-curved-corners"
• crop-names=border1,border2 - Crop to the intersection of the bounding boxes of "border1" and "border2"
• crop-names[layerName]=border-with-curved-corners - Crop the specified layer to the bounding box of the path named "border-with-curved-corners"
• crop-names[layerName]=border1,border2 - Crop the layer to the intersection of the bounding boxes of "border1" and "border2"
• crop-names[layerName]=custom-path - Crop to the bounding box of a custom path named "custom-path"

Note: This operation is ignored if:

• No path with the specified name is found in the layer source image
• The intersection of multiple paths results in an empty region
