BUG: PALETTEINDEX Not Working for Thin Lines on HP PaintJet

RESOLUTION

Instead of using the PALETTEINDEX macro, you can use the PALETTERGB macro to reference colors in your currently selected palette. Sometimes, this may not be desirable because you would have to know all of the RGB values of all indices in your logical palette. In that case, you could use the GetPaletteEntries() function to retrieve the RGB values of the desired logical palette index and call the PALETTERGB macro with those values.

The following example of how you could implement your own PALETTEINDEX function. This function performs the same function as the PALETTEINDEX macro, and works in all cases on the HP PaintJet.

   COLORREF MyPALETTEINDEX(HPALETTE hPalette, WORD wPaletteIndex)

   {
   PALETTEENTRY pe;

   GetPaletteEntries(hPalette, wPaletteIndex, 1, &pe);
   return (PALETTERGB(pe.peRed, pe.peGreen, pe.peBlue));
   }
