Stain applied with the gradient Cold Steel 2


This filter adds stains to the image.

Every stain is created in a layer of its own. The stain layers are randomly moved to let the stains spread out (at the end you may see the boundary of the moved top layer). So after applying the filter you can easily edit (e.g., move, scale, remove) the stains, or create additional stains using the filter again.

Number of stains to add

The number of stains (1-10).

Since every stain is created in a layer of its own, all layers have to be merged to make the appearance of the image. If this option is checked, the relevant layer mode is set to Darken only, otherwise it is set to Normal.

The layer mode determines how the pixels of the layers are combined. In Normal mode, every coffee stain covers the pixels of the layers below. As a rule of thumb, if layer mode Darken only is set, coffee stains covers the corresponding pixels of the layers below them only if these pixels are lighter.

The layer mode determines how the pixels of the layers are combined. If Darken only is unchecked we use Normal mode, and every stain covers the pixels of the layers below. If Darken only is checked, stains cover the corresponding pixels of the layers below them only if these pixels are lighter.
