I'm using TImageEnView to display an image and have used its IEBitmap.IECanvas.TextOut to output text in several places. Now I want to remove these text outputs from the original image without damaging the original picture. Is there a method to achieve this directly?

Hi

If you only want to temporarily show text over the image without modifying it then use one of the following options:

- Add a Text Layer to the image

- Draw to the control canvas or back buffer:

- Save an undo before drawing to the image canvas, and then undo the changes
