I'm not experienced with image manipulation but theoretically there's no reason a file's data couldn't be written into a string. In exchange it may be faster than drawing to canvas, especially with multiple strings if you only need to manipulate part of the image. It would also mean the string is likely to be very long for larger images, so this might take more memory than canvas would and could potentially need to be split into multiple strings. It would, however, involve some complex and possibly difficult to get right string manipulation, to make sure the image data translated correctly and moreso to manipulate the pixels. ![]() This wouldn't require drawing to canvas, only loading the image data as a string instead of an image.
