I have a habit of grabbing lock screen images from web, mostly web comics and their extra galleries. These images often are small, have wrong aspect ratio, or have parts such as speech bubbles, which I'd like to leave out.
I have not yet found a way to "zoom out" or just move the image so that image would cover only part of lock screen. Is this possible with the phone?
Only solution I have found is to put image to OneDrive, download to a PC, edit, save back to OneDrive, then access that from the phone. This is very tedious even when I am close to a computer I can use.
Here's an example of what I mean. Original is from a small public domain image, then there's a simulated result of setting it directly as lockscreen image in phone, and finally a demonstration of my current tedious method, a Paint-edited image of right size. It is not very important how the color outside original image is determined (with Paint it happens by selecting background color before enlarging canvas, or later with flood fill tool).
