Chapter 5. Filters

This chapter describes the various filters in detail. To illustrate the result of applying the filters, each description is accompanied by an sample image with the respective filter applied to it. The original image (with thanks to the photographer, Christian Peper) is shown below at half of the original size. The sample images demonstrating the results of applying the filters, are shown at 25% of the original size.

Note

Some filters yield reasonable results for most images. For other filters though, quite some tweaking needs to be done before the desired outcome is achieved. If a filter does not do what you want, it might need more or less customising.

See the Dialogs chapter for more information on the dialog windows containing the filter settings.

The Bumpmap filter

The Bumpmap filter takes two layers and uses one of these to convert the other one so that it will give an illusion of depth. The object layer (the layer to be transformed) is the actual layer that should receive the three-dimensional looks. The bumpmap layer is a grayscale layer, which is read and used to determine the height for each point of the object layer.

Alternatively, the same layer can be used as both object layer and bumpmap layer.
