typedef struct _ROTATEDLGPARAMS 
{

The ROTATEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImage::DoModalRotate 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 by which to rotate the image entered in the dialog. This angle is measured in hundredths of degrees. Possible values range from -36000 - +36000. A positive value will rotate the image in a clockwise rotation, while a negative value will rotate the image in a counter-clockwise rotation.
bResize	A flag that indicates whether to resize the resulting image as needed. Possible values are:
	Value	Meaning
	TRUE	Check the check box and resize the resulting image as needed.
	FALSE	Clear the check box and do not resize the resulting image.

uRotateFlags	Variable to be updated with a value that represents the type of resizing to perform. Possible values are:
	Value	Meaning
	0	Normal resize.
	ROTATE_RESAMPLE	Resample resize.
	ROTATE_BICUBIC	Bicubic resize.

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_ROTATE_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
	DLG_ROTATE_SHOW_BACKCOLOR	[0x00000008] dialog will show the background color button.
	DLG_ROTATE_SHOW_RESIZE	[0x00000010] dialog will show the resize check box.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
