Syntax

typedef struct _ZOOMBLURDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   L_UINT uDim; 
   L_UINT uStress; 
   POINT ptCenter; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} ZOOMBLURDLGPARAMS,  * LPZOOMBLURDLGPARAMS; 

Members

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

pBitmap

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

uStress

Blur intensity. Possible values range from 0 - 100.

ptCenter

POINT structure that contains the point about which the image is blurred and zoomed. The point should be within the image rectangle coordinates. However, if there is a region in the bitmap, then the point should be within the region.

uDlgFlags

Value Meaning
DLG_ZOOMBLUR_AUTOPROCESS [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.
DLG_ZOOMBLUR_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
DLG_ZOOMBLUR_SHOW_PREVIEW [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.
DLG_ZOOMBLUR_SHOW_TOOL_ZOOMLEVEL [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_ZOOMBLUR_SHOW_PREVIEW flag must be set in order to show these buttons.
DLG_ZOOMBLUR_SHOW_APPLY [0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button.
