The SHEARDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImage::DoModalShear function. After the user closes the dialog box, this structure is updated with information about the user's selections.
typedef struct _SHEARDLGPARAMS{L_UINT uStructSize;pBITMAPHANDLE pBitmap;L_INT nAngle;L_BOOL bHorizontal;COLORREF crBack;L_UINT32 uDlgFlags;LTCOMMDLGHELPCB pfnHelpCallback;L_VOID *pHelpCallBackUserData;} SHEARDLGPARAMS, * LPSHEARDLGPARAMS;
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Pointer to the bitmap handle that references the bitmap used for preview or processing.
A variable to be updated with the angle or shear entered in the dialog. Positive values are for clockwise angles; negative values are for counterclockwise angles. The angle is expressed in hundredths of degrees. Possible values range from -4500 - 4500.
A flag that indicates the shear direction. Possible values are:
| Value | Meaning |
|---|---|
| TRUE | Horizontal shear. |
| FALSE | Vertical shear. |
A variable to be updated with the background fill color entered in the dialog. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
| Value | Meaning |
|---|---|
| DLG_SHEAR_AUTOPROCESS | [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap. |
| DLG_SHEAR_SHOW_CONTEXTHELP | [0x00000002] dialog should contain a context sensitive help icon. |
| DLG_SHEAR_SHOW_PREVIEW | [0x00000004] show preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap. |
| DLG_SHEAR_SHOW_BACKCOLOR | [0x00000008] dialog will show the background color button. |
