This person is obviously a troll, please ignore the malarkey and avoid off-topic feuds.
But what about the off-chance he isn't and is deadly serious? =]
Besides, it's not like he's taking the spotlight off of other terribly popular threads.
I'm obviously deadly serious.
I tried Paint.net, Grafx2, Paint in 7, GIMP and RealWorld Cursor Editor and they are not as comfortable as Paint in XP for me. Trust me. Some people may think differently but this is my opinion and it isn't wrong.
Paint.net - always starts with a white 800x600 image in 99% zoom instead of using last size, always asks whether canvas should be expanded if pasting a larger image (Microsoft removed it for a reason), always shows a color wheel with palette and before RGB sliders (Paint only shows palette which isn't as distracting), no option to clear image (seriously?), always erases with transparent color instead of background color, no quick resizing (Paint has these dots that you can drag to resize)
Grafx2 - limited to 256 colors, requires 8x8 font for GUI, uses side by side zoom, no quick resizing
Paint in 7 - bad palette choice, weird thickness options (1, 3, 5, 8, seriously? Why not 1, 2, 3, 4, 5 as in Paint in XP?), no clear option (again, this distracts me)
GIMP - no clear way to use this as a pixel art editor
RealWorld Cursor Editor (which is a cursor editor but can also edit images) - no clear option or background color, erases with transparent color (requiring constant switching colors), no quick resizing, does not expand canvas on pasting
Paint in XP has all the good features that I need - good palette choice, good thickness options, quick resize, background color that you can erase with, clear option (cannot live without this one), always expands canvas on pasting instead of asking or not doing it.
This is just my opinion. Don't blame me or ban me.
