L_LTDLG_API L_INT L_DlgFreeHandWave(hWndOwner, pDlgParams)
Displays the Free Hand Wave dialog box, and gets the options for L_FreeHandWaveBitmap.
Handle of the window which owns the dialog.
Pointer to a FREEHANDWAVEDLGPARAMS structure to be updated with the values entered by the user, through the dialog. Set members of this structure, before calling this function, to set the dialogs initial values.
This dialog has the following fields:
Use this to select the curve mode to use. There are two choices:
Curve : distorts the image using a curve wave.
Linear : distorts the image using a linear wave.
Use these buttons to flip the curve if the Curve Mode is either Curve or Linear. The following options are available:
Both : Flip the curve vertically and horizontally.
Vertically : Flip the curve vertically.
Horizontally : Flip the curve horizontally.
Use the Reset button to set the curve to its default values.
Use the Load button to load an "*.lhw" file that contains Hand Wave curve settings and the angle setting, using the Load dialog. The loaded file will set new curve and angle settings.
Loading curve and angle settings will overwrite all current curve and angle settings!
Use the Save button to save the curve and angle settings into an "*.lhw" file. This allows you set the same curve and angle settings for other images by re-loading the file.
|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.|
