Re: Problem with hotspots linking

[Christian W. <cwa...@gm...>]

> I opened eqirect.bmp in GIMP, created a new layer, opened hotspot-palette.gif, inkdropped the first color from the palette image, painted a hotspot on new layer of equirect.bmp, repeated three times with next three colors on palette. Removed bottom layer of equirect.bmp to leave only colors and white background. Changed mode of image to Indexed, and selected hotspot.palette.gif to index the image. Saved as hotspotmap.png.

OK, I can reproduce the problem by following these instructions. It appears that GIMP takes the liberty of reordering the colors when you have "remove unused colors from palette" checked in the indexed conversion dialog. Unchecking that box fixes the problem. This results in a larger color palette than strictly necessary, but the effect of that is probably negligible. I haven't found an option for trimming the palette to the used colors afterwards in GIMP.
