How to edit a very big image?

So what I am trying to do here is to be able to take an image and put it on a full size monitor with setTextScale(0.5). The converter I found does a half-decent job but leaves a lot of noise, removing it using a text editor would take a very long time and trying to do so using a monitor is very, very hard due to the fact that its quite inaccurate, plus I am making it more so when doing setTextScale(0.5). So I was wondering if there was a way to edit the image externaly so I can have a nice looking logo sign?

Something like NPaintPro could probably do that, or my own Turtle Architect V2 very soon. I started on a paint image conversion function earlier today, which i might finish when i get home from work :P/>

You didn't get my point at all, I currently have a 143 by 52 computercraft image that I need to edit. nPaintPro does not do that any better than paint for the changes that I want to make. Is there any editor, even if not ingame that would allow me to edit my big image?

As an example, have a look at this image http://pastebin.com/Sihaeiah .

Can you give some more details on the "converter" you're using, and why you're using it?

As far as i know, NPaintPro has an unlimited canvas size, which unlike paint, is not limited by the screen size. So what exactly is the problem?

Forgot to mention - your monitor issues are likely to go away if you're in single-player mode.

You didn't even look at nPaintPro…you could easily do this with the program. It has an unlimited canvas size with scrolling. It also has larger brush sizes, so you can change larger areas at once.
