-Subject: Patch for Motif ConvertToBitmap
-
-Hi Julian,
-
-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!
-
-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.

+Subject: Patch for Motif ConvertToBitmap
+
+Hi Julian,
+
+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!
+
+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,
+
