For best results, portions of the brush that should be transparent (ie, not part of the brush shape) should have the transparent color index. */ in = fopen("star.png", "rb"); brush = gdImageCreateFromPng(in); /* Background color (first allocated) */ black = gdImageColorAllocate(im, 0, 0, 0); gdImageSetBrush(im, brush); /* Draw a line from the upper left corner to the lower right corner using the brush. */ gdImageLine(im, 0, 0, 99, 99, gdBrushed); /* ... Do something with the image, such as saving it to a file... */ /* Destroy it */ gdImageDestroy(im); /* Destroy the brush image */ gdImageDestroy(brush); any of the drawing functions should be able to take gdBrushed or gdStyled or gdStyledBrushed. the fill functions should be able to take gdTiled after gdimagesettile() is called... in c, these work out to be special defined colors, but I don't know the best way to do that in php (eg. imageline($im,0,0,99,99,'gdBrushed')?) I was thinking of having setbrush return gdBrushed, but that would seem to create the illusion of being able to have multiple brushes. (same as styles... and then you couldn't pass in gdStyledBrushed anyway) so should I just pass it in as a string and check for type string and a value of one of the specials, or should I do something else? --jlp
