Transparency transparency

This parameter will underlay a checkerboard grid under your image to show which parts of the image are transparent. Must be set to grid for it to take effect.

Note that the resulting image will not be transparent; it is meant to serve as an illustration of transparency of the original image (without the underlay).

The grid size and colors can be customized by setting grid-size and grid-colors. By default transparency=grid will use a grid-size of 4 and grid-colors will be light grey (D0D7DD) and white (FFFFFF).
