L_LCMRC_API L_INT L_PdfCompInsertSegments(hDocHandle, pBitmap, uSegmentCnt, pSegmentInfo, bIsThereBackGround, rgbBackGroundColor);

LCPDF_HANDLE hDocHandle;	/* handle to an existing PDF document */
pBITMAPHANDLE pBitmap;	/* pointer to a bitmap handle */
L_UINT uSegmentCnt;	/* number of elements in segment array */
LPSEGMENTINFO pSegmentInfo;	/* pointer to the SEGMENTINFO structure */
L_BOOL bIsThereBackGround;	/* flag */
COLORREF rgbBackGroundColor;	/* background color */

Applies the segments specified in pSegmentInfo to the specified bitmap, then compresses and inserts the resulting image into the PDF file in memory.

Parameter	Description
hDocHandle	Handle to an existing PDF document. This handle is obtained by calling the L_PdfCompInit function.
pBitmap	Pointer to the bitmap handle that references the image to be inserted in the PDF file.
uSegmentCnt	Number of elements in the pSegmentInfo parameter. It represents the number of segments that will be applied to pBitmap.
pSegmentInfo	Pointer to the SEGMENTINFO structure that contains an array that has the information for each segment.
bIsThereBackGround	Flag that indicates whether to use the average background color to represent the background of the page in the PDF file. Possible values are:
	Value	Meaning
	TRUE	Use the average color to draw a background color in the generated PDF page before drawing the segments.
	FALSE	Leave the background of the PDF page untouched.
rgbBackGroundColor	Average background color. This parameter is ignored if bIsThereBackGround is FALSE.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

To insert the bitmap using MRC segmentation, use L_PdfCompInsertMRC.
