Syntax
typedef struct _SEGMENTINFO
{
[RECT](../../main/api/windows-structures.html) rcSegmentRect;
[L_UINT](../../main/api/leadtools-basic-data-types.html) uSegmentType;
[COLORREF](../../main/api/windows-structures.html) rgbColors[4];
[L_UINT](../../main/api/leadtools-basic-data-types.html) 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:
| Value | Meaning |
|---|---|
| SEGMENT_BACKGROUND | Background segment. |
| SEGMENT_ONEBIT | 1-bit per pixel segment. |
| SEGMENT_ONEBITBW | 1-bit per pixel black and white segment. |
| SEGMENT_TWOBIT | 2-bits per pixel segment. |
| SEGMENT_TWOBITGRAY | 2-bits per pixel grayscale segment. |
| SEGMENT_GRAY | Grayscale segment. |
| SEGMENT_PICTURE | Picture segment |
| SEGMENT_TWOBITBW | 2-bits per pixel black and white segment |
| SEGMENT_ONECOLOR | The segment has one color. |
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.
