I just spent 2hrs to edit a picture using Paint.
Step1:Zoom in till maximum.(Until u can see the picture is all pixelised.)
Step2:Trace along the drawings with white colour brush.
Step3:Colour the rest of the picture white.
Step4:Save it.(As i go on doing, i just keep saving it fearing that any bug will pop out at any time causing me to redo everything.)
Step5:Shout out loud "Fucking tedious job!!!"
