SLICEBITMAPOPTIONS (original) (raw)
Summary
The SLICEBITMAPOPTIONS structure provides information to extract individual slices from radiographic scanned film.
Syntax
typedef struct _SLICEBITMAPOPTIONS
{
[L_UINT](leadtools-basic-data-types.html) uStructSize;
[L_UINT](leadtools-basic-data-types.html) uMaxDeskewAngle;
[L_INT](leadtools-basic-data-types.html) crFill;
[L_INT](leadtools-basic-data-types.html) uFlags;
} SLICEBITMAPOPTIONS, *pSLICEBITMAPOPTIONS;
Members
uStructSize
Size of the structure. Should be set to sizeof(SLICEBITMAPOPTIONS).
uMaxDeskewAngle
Maximum angle of deskew, in hundredths of a degree. Possible values range from 0 to 1000. (The value in degrees is uMaxDeskewAngle divided by 100). This parameter is used only if the SLC_DESKEW flag is set.
crFill
Color used to fill the background following rotation. This parameter is used only if the SLC_DESKEW flag is set.
uFlags
Flags that indicate whether to deskew the sliced bitmap, which type of interpolation to use when rotating, and whether to cut the slice from the original image. You can use a bitwise OR ( | ) to specify one flag from each group.
The following flags specify whether to deskew the image:
| Value | Meaning |
|---|---|
| SLC_WITHOUTDESKEW | [0x0001] Do not Deskew. |
| SLC_DESKEW | [0x0000] Deskew the sliced bitmap. |
The following flags indicate which type of interpolation to use when rotating:
| Value | Meaning |
|---|---|
| SLC_DSKW_LINEAR | [0x00000000] Do not perform any interpolation methods when rotating. |
| SLC_DSKW_RESAMPLE | [0x00000010] Perform bilinear interpolation when rotating. |
| SLC_DSKW_BICUBIC | [0x00000020] Perform bicubic interpolation when rotating. |
The following flags specify whether to cut the slice from its original image:
| Value | Meaning |
|---|---|
| SLC_WITHOUTCUT | [0x00000000] Do not cut the slice from its original image. Send the NULL value to the callback pBitmap parameter. |
| SLC_CUTSLICES | [0x00000100] Cut the slice from its original image. Send a pointer to the created bitmap to the callback pBitmap parameter. |
