| 950 | NAME |
| 951 | XCreateInsensitivePixmap - create a grayed-out copy of a pixmap |
| 952 | |
| 953 | SYNOPSIS |
| 954 | Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap ) |
| 955 | |
| 956 | DESCRIPTION |
| 957 | This function creates a grayed-out copy of the argument pixmap, suitable |
| 958 | for use as a XmLabel's XmNlabelInsensitivePixmap resource. |
| 959 | |
| 960 | RETURN VALUES |
| 961 | The return value is the new Pixmap id or zero on error. Errors include |
| 962 | a NULL display argument or an invalid Pixmap argument. |
| 963 | |
| 964 | ERRORS |
| 965 | If one of the XLib functions fail, it will produce a X error. The |
| 966 | default X error handler prints a diagnostic and calls exit(). |
| 967 | |

| 1073 | Subject: Patch for Motif ConvertToBitmap |
| 1074 | |
| 1075 | Hi Julian, |
| 1076 | |
| 1077 | I've been working on a wxWin application for image processing. From the |
| 1078 | beginning, I was surprised by the (lack of) speed of ConvertToBitmap, |
| 1079 | till I looked in the source code of image.cpp. I saw that converting a |
| 1080 | wxImage to a bitmap with 8-bit pixels is done with comparing every pixel |
| 1081 | to the 256 colors of the palet. A very time-consuming piece of code! |
| 1082 | |
| 1083 | Because I wanted a faster application, I've made a 'patch' for this. In |
| 1084 | short: every pixel of the image is compared to a sorted list with |
| 1085 | colors. If the color is found in the list, the palette entry is |
| 1086 | returned; if the color is not found, the color palette is searched and |
| 1087 | then the palette entry is returned and the color added to the sorted |
| 1088 | list. |
| 1089 | |
| 1090 | Maybe there is another method for this, namely changing the palette |
| 1091 | itself (if the colors are known, as is the case with tiffs with a |
| 1092 | colormap). I did not look at this, maybe someone else did? |
| 1093 | |
| 1094 | The code of the patch is attached, have a look on it, and maybe you will |
| 1095 | ship it with the next release of wxMotif? |
| 1096 | |
