#include "l_bitmap.h"
#include "lpdfComp.h"

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

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

Parameters

LCPDF_HANDLE hDocHandle

Handle to an existing PDF document. This handle is obtained by calling the L_PdfCompInit function.

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle that references the image to be inserted in the PDF file.

L_UINT uSegmentCnt

Number of elements in the pSegmentInfo parameter. It represents the number of segments that will be applied to pBitmap.

LPSEGMENTINFO pSegmentInfo

Pointer to the SEGMENTINFO structure that contains an array that has the information for each segment.

L_BOOL 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.

COLORREF rgbBackGroundColor

Average background color. This parameter is ignored if bIsThereBackGround is FALSE.

Returns

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

Comments

To insert the bitmap using MRC segmentation, use L_PdfCompInsertMRC.
