Displays the Shear dialog box, and gets the options for LBitmapBase::Shear.
#include "ltwrappr.h"
virtual L_INT LDialogImage::DoModalShear(hWndOwner)
Handle of the window which owns the dialog.
Value | Meaning |
---|---|
SUCCESS_DLG_OK | The "OK" button was pressed, and the dialog exited successfully. |
SUCCESS_DLG_CANCEL | The "Cancel" button was pressed, and the dialog exited successfully. |
< 1 | An error occurred. Refer to Return Codes. |
LDialogImage::SetShearParams must be called before using this function to set the initial values for the dialog. You can get the updated SHEARDLGPARAMS with the values entered by the user through the dialog by using LDialogImage::GetShearParams.
