From the +beginning, I was surprised by the (lack of) speed of ConvertToBitmap, +till I looked in the source code of image.cpp. I saw that converting a +wxImage to a bitmap with 8-bit pixels is done with comparing every pixel +to the 256 colors of the palet. A very time-consuming piece of code! + +Because I wanted a faster application, I've made a 'patch' for this. In +short: every pixel of the image is compared to a sorted list with +colors. If the color is found in the list, the palette entry is +returned; if the color is not found, the color palette is searched and +then the palette entry is returned and the color added to the sorted +list. + +Maybe there is another method for this, namely changing the palette +itself (if the colors are known, as is the case with tiffs with a +colormap). I did not look at this, maybe someone else did? + +The code of the patch is attached, have a look on it, and maybe you will +ship it with the next release of wxMotif? + +Regards, + +Frits Boel +Software engineer at Hubrecht Laboratory, The Netherlands. + */ + +class wxSearchColor +{ +public: + wxSearchColor( void );
