Do as in that link you gave 2. Save the result as PNG 3. Use cairo_image_surface_create_from_png() to get a cairo surface 4. Make a surface pattern from that 5. Set the pattern’s "extend" to CAIRO_EXTEND_REPEAT 6. Use the pattern as a source. http://cairographics.org/manual/cairo-PNG-Support.html http://cairographics.org/manual/cairo-cairo-pattern-t.html http://cairographics.org/manual/cairo-cairo-t.html If you want vectors it’s gonna be more tricky: you’ll need to express the effect you want in terms of paths, colors, gradients, etc. -- Simon Sapin -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
