-I've been working on a wxWin application for image processing. 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!

+                                       1 ) );
+    }

 
 

-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.
+    return ret;
+}

 
 

-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?
