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? + wxCHECK_MSG( Ok(), (WXPixmap) NULL, wxT("invalid bitmap") ); -Regards, - -Frits Boel -Software engineer at Hubrecht Laboratory, The Netherlands. - -*/ + return M_BMPDATA->m_bitmap; +} -class wxSearchColor +WXPixmap wxBitmap::GetDrawable() const { -public: - wxSearchColor( void ); - wxSearchColor( int size, XColor *colors ); - ~wxSearchColor( void ); + wxCHECK_MSG( Ok(), (WXPixmap) NULL, wxT("invalid bitmap") ); - int SearchColor( int r, int g, int b ); -private: - int AddColor( unsigned int value, int pos ); - - int size; - XColor *colors; - unsigned int *color; - int *entry; - - int bottom; - int top; -}; + return M_BMPDATA->m_bpp == 1 ?
