Comments

The Wave Shear dialog.

This dialog has the following fields:

Curve Mode Drop-down list box:

Use this to select the curve mode to use. There are two choices:

- image\Control_Curve_Mode_Curve.gif Curve: distorts the image using a curve wave.

- image\Control_Curve_Mode_Linear.gif Linear: distorts the image using a linear wave.

Flip Buttons:

Use these buttons to flip the curve if the Curve Mode is either Curve or Linear. The following options are available:

- image\Control_Curve_Flip_Both.gif Both. Flip the curve vertically and horizontally.

- image\Control_Curve_Flip_Vertically.gif Vertically. Flip the curve vertically.

- image\Control_Curve_Flip_Horizontal.gif Horizontally. Flip the curve horizontally.

Reset Button:

Use the Reset button to set the curve to its default values.

Load Button:

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.

Note:

Loading curve settings will overwrite all current settings.

Save Button:

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.
