The CYLINDRICALDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalCylindrical 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 the bitmap edges, depending on the type of cylinder, and negative values stretch the pixels toward the central line of the cylinder. The valid range is from −100 to 100.

uType

A value that indicates the cylinder shape. Possible values are:

uDlgFlags

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

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
