SEGMENTINFO

Summary

The SEGMENTINFO structure provides information about a segment in PDF Compressor.

Syntax

typedef struct _SEGMENTINFO 
{ 
   RECT rcSegmentRect; 
   L_UINT uSegmentType; 
   COLORREF rgbColors[4]; 
   L_UINT uColorsCount; 
} SEGMENTINFO, *LPSEGMENTINFO; 

Members

RECT rcSegmentRect

RECT structure that contains the dimensions and position of the segment in an image.

L_UINT uSegmentType

A value that specifies the segment type. Possible values are:

COLORREF rgbColors

Array which specifies the colors being used by this segment, which is available only for the following segment types:

• SEGMENT_BACKGROUND
• SEGMENT_ONEBIT
• SEGMENT_ONEBITBW
• SEGMENT_TWOBIT
• SEGMENT_TWOBITGRAY
• SEGMENT_TWOBITBW
• SEGMENT_ONECOLOR

L_UINT uColorsCount

Number of valid colors in the array of colors specified by rgbColors.

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.

Usage

• LPDFCompressor::ImageCallBack
• LPDFCompressor::InsertSegments
