1754 | Subject: Patch for Motif ConvertToBitmap | |
1755 | ||
1756 | Hi Julian, | |
1757 | ||
1758 | I've been working on a wxWin application for image processing. From the | |
1759 | beginning, I was surprised by the (lack of) speed of ConvertToBitmap, | |
1760 | till I looked in the source code of image.cpp. I saw that converting a | |
1761 | wxImage to a bitmap with 8-bit pixels is done with comparing every pixel | |
1762 | to the 256 colors of the palet. A very time-consuming piece of code! | |
1763 | ||
1764 | Because I wanted a faster application, I've made a 'patch' for this. In | |
1765 | short: every pixel of the image is compared to a sorted list with | |
1766 | colors. If the color is found in the list, the palette entry is | |
1767 | returned; if the color is not found, the color palette is searched and | |
1768 | then the palette entry is returned and the color added to the sorted | |
1769 | list. | |
1770 | ||
1771 | Maybe there is another method for this, namely changing the palette | |
1772 | itself (if the colors are known, as is the case with tiffs with a | |
1773 | colormap). I did not look at this, maybe someone else did? | |
1774 | ||
1775 | The code of the patch is attached, have a look on it, and maybe you will | |
1776 | ship it with the next release of wxMotif? | |
1777 | ||
1778 | Regards, | |
