The MOTIONBLURDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalMotionBlur 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.
bZoomToFit	Flag that indicates the initial zoom level for previewing the image. Possible values are:
	Value	Meaning
	TRUE	Set the initial zoom level to "Zoom to fit".
	FALSE	Set the initial zoom level to "Normal (1:1)".
uDim	Size of the blur effect, in pixels. Possible values range from 3 - 100.
nAngle	Value that represents the direction of the motion, in hundredths of a degree (+/-). Possible values range from -36000 to 36000. If the value is positive, the motion will be clockwise. If the value is negative, the motion is counter-clockwise.
bUnidirectional	Flag that indicates whether the motion extends only in one direction. Possible values are:
	Value	Meaning
	TRUE	The motion blur effect is only in the direction specified in nAngle.
	FALSE	The motion blur effect is along the line with that angle. For example, if nAngle is 0, the blur effect will occur in the 0 degree direction and the 180 degree direction.

uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_MOTIONBLUR_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
	DLG_MOTIONBLUR_SHOW_APPLY	[0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
