This function queries annotation transparent color.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_ARTX_image_reference_transparent_color_get( HIG_ARTX_IMAGE_REFERENCE hMark, LPAT_RGBQUAD lpColor, LPAT_UINT pnDataSize );

Arguments:

Name	Type	Description
hMark	HIG_ARTX_IMAGE_REFERENCE	Annotation handle.
lpColor	LPAT_RGBQUAD	Pointer to storage for the transparent color value.
pnDataSize	LPAT_UINT	Pointer to the variable that on input contains size of buffer specified by lpColor parameter. On output it contains number of bytes copied to lpColor buffer.

Return Value:

Error count.

Supported Raster Image Formats:

This function does not process image pixels.

Remarks:

If the transparent color is specified for the annotation, then it is copied into the output buffer lpColor, and the number of bytes copied is placed into pnDataSize.

If lpColor is NULL and pnDataSize is not NULL, then on output pnDataSize contains the size of AT_RGBQUAD structure.

If lpColor is not NULL and pnDataSize is not NULL and there is no transparent color in the annotation, then on output pnDataSize contains zero.
