TImageEnVect


Declaration

TImageEnVect = class(TImageEnView);


Description

TImageEnVect inherits from TImageEnView (has all its method and properties), and handles editing of vectorial objects.

TImageEnVect encapsulates a TImageEnProc (Proc property) component for image editing/processing and a TImageEnIO (IO property) (you do not need to add extra TImageEnIO and TImageEnProc components to your form). However for loading and saving of vector objects you should use the custom TImageEnVect functions for this.

For rapid UI development a full set of actions is also available.

Note: For new implementations you should use the layer functionality, which supports almost all of the functionality of TImageEnVect, but with better performance and other improvements. To learn more about transitioning your code to TIELayers, read TImageEnVect vs TIELayers.
