Some effects and filters included in Illustrator have texturizing options, such as the Glass, Rough Pastels, Grain, and Fresco effects. The texturizing options can make an object appear as though painted onto various textures, such as canvas or brick, or viewed through glass blocks.
Drag the Scaling slider to enlarge or reduce the effect on the bitmap image’s surface.
Drag the Relief slider to adjust the depth of the texture’s surface.
From the Light Direction pop‑up menu, choose the direction from which you want the light to appear.
Select Invert to reverse the surface’s light and dark colors.
