-Subject: Patch for Motif ConvertToBitmap
+ // Blit picture
-Hi Julian,
+ GC gc = XCreateGC( xdisplay, (Pixmap) M_BMPDATA->m_pixmap, 0, NULL );
+ XPutImage( xdisplay, (Pixmap) M_BMPDATA->m_pixmap, gc, data_image, 0, 0, 0, 0, width, height );
+#ifdef __WXDEBUG__
+ XSync(wxGlobalDisplay(), False);
+#endif
-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!
+ XDestroyImage( data_image );
+ XFreeGC( xdisplay, gc );
-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.
+ // Blit mask
+
+ if (image.HasMask())
+ {
+ GC gc = XCreateGC( xdisplay, (Pixmap) GetMask()->GetBitmap(), 0, NULL );
+ XPutImage( xdisplay, (Pixmap) GetMask()->GetBitmap(), gc, data_image, 0, 0, 0, 0, width, height );
-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?
+ XDestroyImage( mask_image );
+ XFreeGC( xdisplay, gc );
+ }
+ }
-The code of the patch is attached, have a look on it, and maybe you will
-ship it with the next release of wxMotif?
+ return TRUE;
