On my Mac, erasing an all white background is easy - just a couple clicks. On the iPad...I cannot seem to figure it out for the life of me. I can use the eraser tool to manually erase anything I want, of course, but how do I do a bulk, background erase? For example - I have an image that merged: 3 layers, white background, image 1, image 2. The two individual pics are clear and distinct with their own dark border. I just want to click and have the white background turn transparent.
I don't believe the magic eraser is available yet on the iPad but it will more than likely be there soon. But if you're doing a white background that needs to be eliminated, the select subject feature might help
