I could also store the style info that setstyle is called with. but I'd have weirdness trying to call a drawing function with a style and a brush (gdStyledBrushed). that's why I discarded that option. short of adding an additional optional parameter or passing the thing in as an array or adding a function to merge a brush and a style into a styled brush, I'd be at a loss to come up with a reasonably clean solution. I think I'd lean towards something like int imageSetStyledBrush(int style,int brush), but it's deviating from the gd library a bit. how important is that? it would be nice to be able to switch things around at will (as a side effect, you'd be able to specify brushes, tiles, and styles without specifying which image they'd be linked to, and just use them to draw on any of the images that are open... that's almost a bad thing, since colors don't work like that, but it's still nice.). --jlp
