plug_in_bump_map_tiled (April 2000, 3.0-pre1-ac2)

NAME

plug_in_bump_map_tiled - Create an embossing effect using a tiled image as a bump map

SYNOPSIS

plug_in_bump_map_tiled (run_mode,image,drawable,bumpmap,azimuth,elevation,depth,xofs,yofs,waterlevel,ambient,compensate,invert,type)

DESCRIPTION

This plug-in uses the algorithm described by John Schlag, "Fast Embossing Effects on Raster Image Data" in Graphics GEMS IV (ISBN 0-12-336155-9). It takes a drawable to be tiled and applied as a bump map to another image and produces a nice embossing effect.
