To ensure exported images are perfectly crisp and as sharp as when originally captured, I have to do the following:
- take the PrtScr screenshot and paste onto a page, in my case, Xara Photo & Graphic Designer v16.
- scale the screenshot image to 100% (see first screenshot below)
- export the selected image as a png ensuring the export height and width pixel size are the same as the original screenshot size. To find this out take a look in the Bitmap gallery (see second screenshot). This will change the dpi value to that of your Windows system display.
In my particular case I run my Windows system with a custom scale set to 120% to make everything slightly easier to read on my laptop. So when I export a png I have to set the export dpi to 115. Once you've worked out what this value is for your system you can just type it in without worrying about pixel sizes.
I don't fully understand all this, but it works for me, so hope it put you on the right track.
