L_LCMRC_API L_INT L_PdfCompInsertMRC(hDocHandle, pBitmap, pPDFOptions)
LCPDF_HANDLE hDocHandle; |
/* handle to an existing PDF document */ |
pBITMAPHANDLE pBitmap; |
/* pointer to a bitmap handle */ |
LPPDFCOMPOPTIONS pPDFOptions; |
/* pointer to the PDFCOMPOPTIONS structure */ |
(Document Required) Segments the specified image using MRC segmentation, compresses it, and inserts the image in the PDF file in memory. This function is available in the Document Toolkit.
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. |
pPDFOptions |
Pointer to the PDFCOMPOPTIONS structure that contains options used to write the image to the PDF file in memory. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
To insert the bitmap without using MRC segmentation, use L_PdfCompInsertNormal.
This function calls the pPDFCOMP_IMAGECALLBACK to allow the user to accept or reject the addition of any segment to the PDF document.

Example
This example inserts an image to pdf document and uses the MRC to make a proper segment for this image , in this sample we don't need to add Back ground segment.
