Class MediaFile

TopLevel.Object
- dw.content.MediaFile

This class represents references to media content (such as images) located within Commerce Cloud Digital or on external systems.

Parameter transform:

Some methods allow the specification of image transformation parameters. Image transformation is only performed if the Dynamic Imaging Service (DIS) is available for the Commerce Cloud Digital instance, otherwise a standard static content URL is returned. The to-be-transformed image needs to be hosted on Commerce Cloud Digital.

Image transformation parameters are specified as JavaScript object literal. They are translated into URL parameters. See Create Image Transformation URLs.

Type of transformation	Parameters	Description
Scale an image	`scaleWidth` `scaleHeight` `scaleMode`	The `scaleWidth` and `scaleHeight` parameters are both integers; setting one of these parameters triggers a scaling operation. If both are provided, the one that scales the image less is used to calculate the scale factor. The image is then automatically cropped accord to the second dimension, with a centered position of the cropped area. If the parameter would scale the image larger, only this operation is applied, if the image remains within acceptable pixel dimensions. Note: `scaleMode` can only be used in combination with `scaleHeight` and `scaleWidth`. The `scaleMode` parameter can be set to `cut` or `fit`. The default `scaleMode` is `cut`, the behavior of which is explained above. If you specify `fit` as the `scaleMode`, the system scales the image into the given box of dimensions while keeping the aspect ratio (possibly resulting in a smaller image in one dimension).
Overlay an image	`imageX` `imageY` `imageURI`	The `imageX` and `imageY` parameters are both integers. Valid values for these parameters are 0 or greater. Supported formats are `png`, `jpg`, `jp2`, and `gif`. The `imageURI` parameter can be set to the absolute path of the overlaid image. The value of the `imageURI` parameter must be given in proper URL encoding, and it cannot exceed 400 characters in length. The path may include query string parameters, which supports dynamically generating the overlaid image itself through this service; that is, the overlaid image can itself be a transformed image. If the overlaid image extends over the primary image's boundaries, the overlaid image is cropped so that it fits directly over the primary image.
Crop an image	`cropX` `cropY` `cropWidth` `cropHeight`	The `cropX`, `cropY`, `cropWidth`, `cropHeight` parameters are integers. All four parameters must be specified to trigger a cropping operation. Valid values for the `cropX` and `cropY` parameters are 0 or greater. If the crop location defined by `cropX` and `cropY` is outside the image area, nothing is cropped. Valid values for the `cropWidth` and `cropHeight` parameters are 10 or greater. If the `cropWidth` and `cropHeight` parameters specify a size that is greater than the original image, the crop area is reduced to the actual image area. If `cropWidth` and `cropHeight` are 0 or less, no transformation is applied.
Format an image	`format`	The `format` parameter specifies the target format of image. Supported formats are `png`, `jpg`, `jp2`, and `gif`. If no target format is specified, no format conversion is performed. The attribute value must reference the source image. Source image's format is recognized by the file extension which must be `tif`, `tiff`, `jpg`, `jpeg`, `png`, or `gif`. In the generated URL the file extension of the target format is used in the URL path. This is to make sure the image is loaded from an URL with a matching file extension. The source format is provided as URL parameter.
Adjust image compression quality	`quality`	The `quality` parameter specifies a quality setting for `jpg` and `jp2` images, and specifies the compression level for `png` images. For `jpg` and `jp2` images, you can set values from 1–100 for the highest quality. The default quality is 80. If you're not changing the default quality, you don't need to pass in a value. For `png` images, the quality setting has no effect on the appearance of the `png`, since the compression is always lossless. Instead you can use the quality setting to set the zlib compression level and filter-type for PNG images. The tens digit sets the zlib compression level(1-9). The ones digit sets the filter type. If the `png` setting is not present or set to 0, it uses a default value of 75. If this setting is set to 100, it actually equals the quality setting 90.
Adjust Metadata stripping	`strip`	The `strip` parameter specifies if metadata like EXIF and color profiles is stripped from the image during transformation. Valid values for the `strip` parameter are between `true` and `false`. The default is `true`
Change background color	`bgcolor(color) or bgcolor(color+alpha)`	The `bgcolor` parameter specifies the background color for images that support transparency as well as JPEG images when being converted from a format that supports transparency. Optionally, alpha setting for PNG images are also supported. `bgcolor` expects a 6 digit hexadecimal value of RGB with an optional two hexadecimal characters representing alpha value that determines transparency. FF0000 = Red FF000077 = Red with 50% transparency Alpha values are optional. When the alpha value is omitted, the resulting color is opaque. Alpha values are only valid when the image output format is PNG.

Example:

The following code

var url = product.getImage('thumbnail', 0).getImageURL({scaleWidth: 100, format: 'jpg'});

will produce an image transformation URL like

http://<image server host name>/.../on/demandware.static/.../<path to image>/image.jpg?sw=100&sfrm=png.
