typedef struct _MOTIONBLURDLGPARAMS
} MOTIONBLURDLGPARAMS, * LPMOTIONBLURDLGPARAMS;
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.
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Pointer to the bitmap handle that references the bitmap used for preview or processing.
Flag that indicates the initial zoom level for previewing the image. Possible values are:
|TRUE||Set the initial zoom level to "Zoom to fit".|
|FALSE||Set the initial zoom level to "Normal (1:1)".|
Size of the blur effect, in pixels. Possible values range from 3 - 100.
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.
Flag that indicates whether the motion extends only in one direction. Possible values are:
|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.|
User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
|DLG_MOTIONBLUR_AUTOPROCESS||[0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_MOTIONBLUR_SHOW_CONTEXTHELP||[0x00000002] dialog should contain a context sensitive help icon.|
|DLG_MOTIONBLUR_SHOW_PREVIEW||[0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.|
|DLG_MOTIONBLUR_SHOW_TOOL_ZOOMLEVEL||[0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_MOTIONBLUR_SHOW_PREVIEW flag must be set in order to show these buttons.|
|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.|
