The SMOOTHDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogDocument::DoModalSmooth function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Members

uStructSize

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

pBitmap

Pointer to the bitmap handle that references the 1-bit bitmap used for preview or processing.

bZoomToFit

Flag that indicates the initial zoom level for previewing the image. Possible values are:

Smooth

A SMOOTH structure that LEADTOOLS uses to perform the smoothing operation. You should pass valid pBitmapRegion address and fill the uBitmapStructSize with the proper value.

✎ NOTE

It's the user's responsibility to free the region in pBitmapRegion, if there is one, using LBitmapRgn::Free.

crWhiteArea

Color used to fill the smoothed white areas. This is used only for dialog previewing purposes. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.

crBlackArea

Color used to fill the smoothed black areas. This is used only for dialog previewing purposes. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.

uDlgFlags

User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
