There are three shortcuts that combine common sets:
- ppeColorAdjustments
- ppeEditingFunctions
- ppeSpecialEffects
Examples
// Prompt user to perform color adjustment on the current imageImageEnView1.Proc.DoPreviews( ppeColorAdjustments );
// Prompt user to perform image effects on the current image
ImageEnView1.Proc.DoPreviews( ppeSpecialEffects );
// Prompt user to perform editing operations the current image
ImageEnView1.Proc.DoPreviews( ppeEditingFunctions );
