2091 | Subject: Patch for Motif ConvertToBitmap | |
2092 | ||
2093 | Hi Julian, | |
2094 | ||
2095 | I've been working on a wxWin application for image processing. From the | |
2096 | beginning, I was surprised by the (lack of) speed of ConvertToBitmap, | |
2097 | till I looked in the source code of image.cpp. I saw that converting a | |
2098 | wxImage to a bitmap with 8-bit pixels is done with comparing every pixel | |
2099 | to the 256 colors of the palet. A very time-consuming piece of code! | |
2100 | ||
2101 | Because I wanted a faster application, I've made a 'patch' for this. In | |
2102 | short: every pixel of the image is compared to a sorted list with | |
2103 | colors. If the color is found in the list, the palette entry is | |
2104 | returned; if the color is not found, the color palette is searched and | |
2105 | then the palette entry is returned and the color added to the sorted | |
2106 | list. | |
2107 | ||
2108 | Maybe there is another method for this, namely changing the palette | |
2109 | itself (if the colors are known, as is the case with tiffs with a | |
2110 | colormap). I did not look at this, maybe someone else did? | |
2111 | ||
2112 | The code of the patch is attached, have a look on it, and maybe you will | |
2113 | ship it with the next release of wxMotif? | |
2114 | ||
2115 | Regards, | |
