In This Topic

This function sets a single palette entry in image hIGear's DIB palette.

Declaration:

AT_ERRCOUNT ACCUAPI IG_palette_entry_set ( HIGEAR hIGear, const LPAT_RGB lpRGBEntry, UINT nIndex );

Arguments:

Name	Type	Description
hIGear	HIGEAR	HIGEAR handle of image.
lpRGBEntry	const LPAT_RGB	Far pointer to an AT_RGB struct containing the three color values to be set into the palette entry. Note that this is not an AT_RGBQUAD struct. Also note that the order is Blue, Green, Red in an AT_RGB struct.
nIndex	UINT	Which palette entry to set, 0 to 255.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

Indexed RGB - 1…8 bpp.

Sample:

None

Example:

	Copy Code
HIGEAR hIGear; /* HIGEAR handle of image / AT_RGB rgbPaletteColor; / Will hold returned color / AT_ERRCOUNT Errcount; / Returned count of errors onstack / / Set palette entry 255 to a medium-bright yellow, intensity 175: / rgbPaletteColor.b = 0; / There's no blue in yellow */ rgbPaletteColor.r = rgbPaletteColor.g = 175; nErrcount = IG_palette_entry_set ( hIGear, &rgbPaletteColor, 255 );

Copy Code

HIGEAR hIGear;              /* HIGEAR handle of image  */
AT_RGB rgbPaletteColor;     /* Will hold returned color */
AT_ERRCOUNT      Errcount;         /* Returned count of errors onstack */
/* Set palette entry 255 to a medium-bright yellow, intensity 175:  */
rgbPaletteColor.b = 0;     /* There's no blue in yellow */
rgbPaletteColor.r  =  rgbPaletteColor.g  =  175;
nErrcount = IG_palette_entry_set ( hIGear, &rgbPaletteColor, 255 );
