Fit-in
Use the fit-in argument to resize the image to fit within the specified dimensions without cropping.
To fill the remaining space with color, apply the fill filter: filters:fill(CCCCCC) using a hexadecimal RGB value (omit the #). For transparent fills, use filters:fill(transparent) combined with the format filter: :format(png).
In the interactive demo below, enable fit-in by enabling the background settings.
