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. |
