Sets or clears the color-remap table for a specified category
#include <GDIPlus.au3>
_GDIPlus_ImageAttributesSetRemapTable ( $hImageAttributes [, $aColorMap = 0 [, $iColorAdjustType = 0 [, $bEnable = True]]] )
| $hImageAttributes | A pointer to an ImageAttribute object. |
| $aColorMap | [optional] An array of old and new colors: [0][0] - Number of old and new colors [1][0] - Old color 1 [1][1] - New color 1 [2][0] - Old color 2 [2][1] - New color 2 [n][0] - Old color n [n][2] - New color n |
| $iColorAdjustType | [optional] The category for which the output channel color-profile file is set or cleared: 0 - Color adjustment applies to all categories that do not have adjustment settings of their own 1 - Color adjustment applies to bitmapped images 2 - Color adjustment applies to brush operations in metafiles 3 - Color adjustment applies to pen operations in metafiles 4 - Color adjustment applies to text drawn in metafiles |
| $bEnable | [optional] A boolean value that specifies whether a separate color remap table is enabled for the category specified by the type parameter. |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
During rendering, any color that matches one of the old colors in the remap table is changed to the corresponding new color.
