Watermark Tile

Tiles the watermark on top of the image in the requested pattern when the mark parameter is specified.

Valid value is grid. The default value is grid.

The watermark family of parameters are used to place a single mark in a specific location. The watermark is then tiled in a grid pattern around the single mark.

Note: If mark-align is not set, the default top, left will be used for a tiled watermark. This is different from the default bottom, right for a single mark.

mark-tile=grid
