I often have to apply for refund using credit card and bank website images (see below). I need to eliminate identifying info and non-relevant numbers. I've figured out how to do this by using 'Rectangle Select' then choosing the color white on the color wheel then using "Paint Bucket" tool then adjusting the tolerance to 100% then fill. This is a lot of steps for one rectangle. Is it possible to select and retain several rectangles and then simply use the Paint Bucket tool once to fill them all? This would be analogous to using a redaction tool in a pdf reader (which works fine for text pdfs but not images).
