Comments

LPSEGMENTINFO is a pointer to a SEGMENTINFO structure. Where the function parameter type is LPSEGMENTINFO, you can declare a SEGMENTINFO variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a LPSEGMENTINFO variable is necessary only if your program requires a pointer.

This structure is used by the following functions:

L_PdfCompInsertSegments

pPDFCOMP_IMAGECALLBACK
