Derivatives Configurations (Configs)

The dimensions of the resulting derivative image(s). Setting both dimensions, width and height, will resize to exactly to those dimensions.

Setting one dimension, width or height, will create a derivative image with the same aspect ratio as the original image, but will restrict the maximum width or height to the dimension set.

Leaving both dimensions empty will use the original dimensions, meaning it will not resize the image, but it will apply any other settings like compression, sampling filter, and file type.

The optional output format of the config that will override the default file type of the original image.

The default file type is inherit, which means the file type of the original image will be used for all derivative images.

The optional compression level of the resulting derivative image(s). Higher compression levels result in smaller file sizes, but lower image quality. Compression is only applied if the file type is jpg.

The fit of the resulting derivative image(s). cover will scale and crop the image to fit the dimensions, while contain will scale the image to fit the dimensions, keeping the aspect ratio and filling the remaining space with the background color.

The background color of the resulting derivative image(s). This is only used if the fit is contain.

The sampling filter to use when creating the derivative image(s).

The sampling filter controls how pixels are calculated when resizing images. Higher quality filters like Lanczos3 provide better detail and smoother edges, while simpler filters like Nearest are faster but may show artifacts.

The default sampling filter is catmull-rom.

The units of the resulting derivative image(s).

The DPI (dots per inch) of the resulting derivative image(s). This is only used if the units are inches in. If the units are pixels px, the DPI is 72

The default DPI is 72.

Whether to create a 2x image variation along with the 1x image.

Whether to create a 3x image variation along with the 1x and/or 2x images.
