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.
