The BENDINGDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalBending 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

Ignored.

bZoomToFit

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

nValue

Amount of stretching, where positive values stretch the pixels toward edges, and negative values stretch the pixels toward the center. Possible values range from −500 to 500.

ptCenter

A POINT structure that contains the center of the arc. This is ignored when either BND_HORZ or BND_VERT is set in the uBendingFlags member. The center point must be defined inside the bitmap or inside the region, if the bitmap has a region.

crFill

The COLORREF value that specifies the fill color for any exposed areas. 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.

uBendingFlags

Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR (|) to specify one flag from each group.

uDlgFlags

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

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
