IG_palette_entry

This function obtains from image hIGear's DIB palette, the palette entry indicated by nIndex.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_palette_entry_get ( HIGEAR hIGear, LPAT_RGB lpRGBEntry, UINT nIndex );

Arguments:

Name	Type	Description
hIGear	HIGEAR	HIGEAR handle of image.
lpRGBEntry	LPAT_RGB	Far pointer to an AT_RGB struct to receive the three color values of the palette entry. (Note that this is not an AT_RGBQUAD struct. Also note that the order of the bytes is Blue, Green, Red in an AT_RGB struct.)
nIndex	UINT	Which palette entry to get, 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:

Image Processing, Pixel Access

Example:

	Copy Code
HIGEAR hIGear; /* HIGEAR handle of image / AT_RGB rgbPaletteColor; / Will hold returned color / AT_ERRCOUNT nErrcount; / Returned count of errors on stack/ / Get palette entry 255: */ nErrcount = IG_palette_entry_get ( hIGear, rgbPaletteColor, 255 );

Copy Code

HIGEAR hIGear;           /* HIGEAR handle of image    */
AT_RGB rgbPaletteColor;  /* Will hold returned color   */
AT_ERRCOUNT nErrcount;        /* Returned count of errors on stack*/
/* Get palette entry 255: */
nErrcount = IG_palette_entry_get ( hIGear, rgbPaletteColor, 255 );
