This program is a replacement for paintutils and the paint program. In one.

Current version: 2
Get it here: Q7AQ1n2Y

PNG converter:
http://puu.sh/gtCf5/5647b88d6f.rar

Features:

In - game editor
All in one, no other dependencies
Converts paintutils format to his own format
Image panning (Writing images bigger than the terminal)
Painting using text
Automated writing without affecting background
In-game documentation
Write buffer. Gets almost all user input (Mouse dragging)
User friendly

API functions:
Drawing an image to the screen
[indent=1]paint.drawImage( <File name> <xPos> <yPos> <redirection object> )[/indent]
Drawing text OVER the last image, not affecting background. (relative to the image position)
[indent=1]paint.overWrite( <Text>, <xPos>, <yPos>,<color> )[/indent]
Converting paintutils format to betterpaint format
[indent=1]paint.import( <Source (paintutils format)>, <Destination (betterpaint format)> )[/indent]

Usage:

[indent=1]paint[/indent]
[indent=2]– Does nothing, allows for loading quietly as api.[/indent]
[indent=1]paint <file name>[/indent]
[indent=2]– Opens or creates a file to paint[/indent]
[indent=1]paint import <source> <destination>[/indent]
[indent=2]– Converts paintutils format to betterpaint format, Source as paintutils file. Destination as betterpaint format.[/indent]

Disclaimer:
For using this program/api in one of your programs you are free to do whatever you want. As long as I get a bit of credit (only if there is a credits section!)
Feedback is always welcome and I'd be happy to improve the program further if desired!

Thank you very much, I would like to know if someone actually uses it, If anyone uses the program, do they mind posting some screenshots? I made this program to make the lives of the programmers easier :D/> (and I am curious what it will be used for, haha)

Well I actually kind of designed my own similar function, but it doesnt work correctly. Here it is:

local function drawPixel(x,y,character,fgColor,bgColor)

end
function advancedPaint(x,y,image,text)
local textTable = {}
local xPos = 1
local yPos = 1
local currColor = colors.black
local buffer = {}
for token in string.gmatch(text,"[^%%]+") do
  buffer[#buffer+1] = token
end
print("3")
print(textutils.serialize(buffer))
for i,v in pairs(buffer) do
  if string.sub(v,1,1) == "<" and string.sub(v,-1,-1) == ">"then
   print("ana")
   local toAnalize = string.sub(v,2,-2)
   if toAnalize == "newLine" then
    xPos = 1
    yPos = yPos + 1
   else
    local internalBuffer = {}
    for token in string.gmatch(toAnalize,"[^:]+") do
	 internalBuffer[#internalBuffer+1] = token
    end
    if internalBuffer[1] == "fgColor" then

    end
   end
  else
   print("str")
   for k=1,#v do

    textTable[yPos][xPos][1] = currLeter

I will include BetterPaint as an object type in the Interact API (my GUI API, check at the link I gave you). Is that OK? I think it (betterpaint) is super useful. ;)/>

That's completely fine! I feel honored that you use my api.
if you feel like you need more api functions or something I have not noticed, feel free to post them here and I will try to add them!

You can. paint.drawImage(<file>, <xPos>, <yPos> [,redirection target]) does that for you. the same way as paintutils does
if no redirection target is given, it will simply print in the terminal. :D/>
