11.4.1. Overview

Figure 17.222. Example for the “Coffee Stain” filter

Original image

“Coffee Stain” applied

This filter adds realistic looking coffee 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 coffee stains, or create additional stains using the filter again.

11.4.2. Activate the filter

The filter is found in the image window menu under Filters → Decor → Coffee Stain….

11.4.3. Options

Figure 17.223. “Coffee Stain” options

Stains

The number of the coffee stains (1-10).

Darken only

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.
