To produce their effects, some filters load and use other images, such as textures and displacement maps. These filters include the Conté Crayon, Displace, Glass, Lighting Effects, Rough Pastels, Texturizer, Underpainting, and Custom filters. Not all of these filters load images or textures in the same way.

Set texture and glass surface controls

The Rough Pastels, Underpainting, Glass, Conté Crayon, and Texturizer filters have texturizing options. These options make images appear as if they were painted onto textures such as canvas and brick, or viewed through surfaces such as glass blocks or frosted glass.

Define undistorted areas

The Displace, Shear, and Wave filters in the Distort submenu and the Offset filter in the Other submenu let you treat areas undefined (or unprotected) by the filter in the following ways:

Fills the undefined space with content from the opposite edge of the image.

Extends the colors of pixels along the edge of the image in the direction specified. Banding may result if the edge pixels are different colors.

Fills the selected area with the current background color.

Apply the Dust And Scratches filter

Apply the Displace filter

The Displace filter shifts a selection using a color value from the displacement map—0 is the maximum negative shift, 255 the maximum positive shift, and a gray value of 128 produces no displacement. If a map has one channel, the image shifts along a diagonal defined by the horizontal and vertical scale ratios. If the map has more than one channel, the first channel controls the horizontal displacement, and the second channel controls the vertical displacement.

The filter creates displacement maps using a flattened file saved in Adobe Photoshop format. (Bitmap mode images are unsupported.)
