L_LTDLG_API L_INT L_DlgFreeHandWave(hWndOwner, pDlgParams)

Displays the Free Hand Wave dialog box, and gets the options for L_FreeHandWaveBitmap.

Comments

The Free Hand Wave 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:

• 

  Curve: distorts the image using a curve wave.

• 

  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:

• 

  Both. Flip the curve vertically and horizontally.

• 

  Vertically. Flip the curve vertically.

• 

  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 "*.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!

Save Button:

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.
