Parameter |
Description |
hWndOwner |
Handle of the window which owns the dialog. |
pDlgParams |
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 dialog’s initial values. |
Comments
The Free Hand Wave dialog can be seen below:
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. NOTE: 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.
Returns
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. |
