L_LTDLG_API L_INT L_DlgWaveShear(hWndOwner, pDlgParams)
Displays the Wave Shear dialog box, and gets the options for L_FreeHandShearBitmap.
Handle of the window which owns the dialog.
Pointer to a WAVESHEARDLGPARAMS 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.
|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.|
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 "*.lsr" file that contains Shear Wave curve settings, using the Load dialog. The loaded file will set a new curve.
Loading curve settings will overwrite all current settings.
Use the Save button to save curve settings into an "*.lsr" file. This allows you set the same curve settings for other images by re-loading the file.
