SHEARDLGPARAMS

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.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pBitmap	Ignored.
nAngle	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.
bHorizontal	A flag that indicates the shear direction. Possible values are:
	Value	Meaning
	TRUE	Horizontal shear.
	FALSE	Vertical shear.

crBack	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.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_SHEAR_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
	DLG_SHEAR_SHOW_BACKCOLOR	[0x00000008] dialog will show the background color button.
	DLG_SHEAR_SHOW_HORIZONTAL	[0x00000010] dialog will show the horizontal check box.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
