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. | |
