This function builds the result palette.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_colorspace_conversion_result_palette_get( HIGCSCONVERTER hCSConverter, AT_RGBQUAD* palette, AT_INT* paletteLength );

Arguments:

Name	Type	Description
hCSConverter	HIGCSCONVERTER	Handle of color space converter.
palette	AT_RGBQUAD*	Array of palette entries.
paletteLength	AT_INT*	Number of palette entries.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

All pixel formats supported by ImageGear Professional.

Sample:

None

Example:

	Copy Code
/* Use the color space converter to convert an image to 8-bit indexed, no alpha or extra channels / AT_ERRCOUNT nErrcount; / Number of errors on stack / HIGCSCONVERTER hCSConv; / Color space converter handle / HIGEAR hImage; / HIGEAR handle of image / AT_INT depths[] = {8}; / Result channel depths / AT_RGBQUAD pal[256]; / Result palette / AT_INT nEntries; / # of palette entries */ nErrcount = IG_colorspace_conversion_create_from_image( hImage, IG_COLOR_SPACE_ID_I, depths, 1, NULL, &hCSConv); nErrcount = IG_colorspace_conversion_apply_to_image( hCSConv, hImage); nErrcount = IG_colorspace_conversion_result_palette_get( hCSConv, pal, &nEntries); nErrcount = IG_colorspace_conversion_destroy(hCSConv);

Copy Code

/* Use the color space converter to convert an image 
to 8-bit indexed, no alpha or extra channels */
AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGCSCONVERTER hCSConv; /* Color space converter handle */
HIGEAR hImage;          /* HIGEAR handle of image */
AT_INT depths[] = {8};  /* Result channel depths */
AT_RGBQUAD pal[256];    /* Result palette */
AT_INT nEntries;        /* # of palette entries */
nErrcount = IG_colorspace_conversion_create_from_image(
    hImage, IG_COLOR_SPACE_ID_I, depths, 1, NULL, &hCSConv);
nErrcount = IG_colorspace_conversion_apply_to_image(
    hCSConv, hImage);
nErrcount = IG_colorspace_conversion_result_palette_get(
    hCSConv, pal, &nEntries);
nErrcount = IG_colorspace_conversion_destroy(hCSConv);

Remarks:

If the resultant color space is indexed, paletteLength will be filled with the quantity of palette entries.
