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 +wxBitmap::wxBitmap( const wxString &filename, int type ) { -public: - wxSearchColor( void );
