3.7. Colormap object

Colormap objects are used to represent the Colormap type. A Colormap object can be obtained using the widget method CreateColormap (which also needs a Visual Info object) or the widget method DefaultColormapOfScreen. A Colormap object can be used in the widget method SetWindowColormap and as the colormap resource of widgets.

Colormap objects (cm_objects) have the following methods:

AllocColor (red, green, blue) -- Method on Colormap object: Returns (pixel, red, green, blue, flags). This function corresponds with XAllocColor.

AllocColorCells (contig, nplanes, npixels) -- Method on Colormap object: Returns (plane_masks_list, pixels_list). This function corresponds with XAllocColorCells.

AllocNamedColor (color_name) -- Method on Colormap object: Returns ((screen_def.pixel, screen_def.red, screen_def.green, screen_def.blue, screen_def.flags), (exact_def.pixel, exact_def.red, exact_def.green, exact_def.blue, exact_def.flags)). This function corresponds with XAllocNamedColor.

FreeColors (pixel_list, planes) -- Method on Colormap object: Returns None. This function corresponds with XFreeColors.

Install () -- Method on Colormap object: Returns None. This function corresponds with XInstallColormap.

InstallColormap () -- Method on Colormap object: Returns None. This function corresponds with XInstallColormap.

LookupColor (color_name) -- Method on Colormap object: Returns ((exact_def.pixel, exact_def.red, exact_def.green, exact_def.blue, exact_def.flags), (screen_def.pixel, screen_def.red, screen_def.green, screen_def.blue, screen_def.flags)). This function corresponds with XLookupColor.

ParseColor (color_name) -- Method on Colormap object: Returns (pixel, red, green, blue, flags). This function corresponds with XParseColor.

QueryColor (pixel) -- Method on Colormap object: Returns (pixel, red, green, blue, flags). This function corresponds with XQueryColor.

QueryColors (pixel_list) -- Method on Colormap object: Returns XColor_list. This function corresponds with XQueryColors.

StoreColors (color_list) -- Method on Colormap object: Returns None. This function corresponds with XStoreColors.
