actionscript 3, add a watermark to image and save

Question

my task -

1. Open a picture from computer
2. Add the watermark in the corner
3. Ask a request to download edited image back to computer

how is it possible?

• general image - jpg.
• watermark- it does not matter. Use all what you want

Answer 1

1. Opening and saving files: FileReference class. See FileReference.browse() and FileReference.save(). Note: you can only open or save files upon user interaction (i.e. user presses a button, you open the OS browse dialog).
2. The bitmap you load is represented by BitmapData class. When you have a picture and a watermark image, you can draw the latter on the former using BitmapData.draw().
3. Use FileReference.save() as pointed out in 1.
