The WINDDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalWind 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 bitmap used for preview or processing.

bZoomToFit

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

uDim

Size, in pixels, of the thin lines used to create the wind effect. Possible values range from 2 - 100.

nAngle

Angle of the thin lines used to create the wind effect, in hundredths of a degree. Possible values range form −36000 to 36000.

uOpacity

Density, in pixels, of the thin lines used to create the wind effect. Possible values range from 0 - 100.

uDlgFlags

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

pfnHelpCallback

Ignored.

pHelpCallBackUserData
