[Released] Bitmap Drawing API v0.8 (open source)

I've just finished and uploaded my project to GitHub:
https://github.com/ProtoTurtle/UnityBitmapDrawing

Example project here:
https://github.com/ProtoTurtle/BitmapDrawingExampleProject

This uses a MIT license so you can do pretty much anything with it as long as you keep the license intact. Commercial projects, further open source, etc. are all fine.

Bitmap Drawing API
At it's core this library provides and easy way to manipulate your textures as bitmaps. I find it very useful for visual debugging, creating procedural art or creating tools. You only need one file!

You have an existing texture or you create an empty texture and you can draw lines, circles and rectangles on it (filled with color or just the outline).

Features

• 
  
  
  • DrawPixel(position, color) - Draws a pixel but with the top left corner being position (x = 0, y = 0)
  • DrawLine(start, end, color) - Draws a line between two points
  • DrawCircle(position, radius, color) - Draws a circle
  • DrawFilledCircle(position, radius, color) - Draws a circle filled with a color
  • DrawRectangle(rectangle, color) - Draws a rectangle or a square
  • DrawFilledRectangle(rectangle, color) - Draws a rectangle or a square filled with a color
  • FloodFill(position, color) - Starts a flood fill of a certaing at the point

Uses Extension Methods so it's super simple to start using, you only type

Code (csharp):

1. using ProtoTurtle.BitmapDrawing;

And all the bitmap drawing methods are available to your Texture2D instances.



I'm looking for feedback on this and I'm taking feature requests. I just wanted to get this first version out and see if there's any interest in this tool.


Coming up next:
- Faster flood fill (the bottleneck is mostly comparing Unity's Color structs) - if anyone has a good idea about this, please let me know! Running the flood fill with ints instead of Colors makes it a ton faster but then the problem is converting the Colors to ints and then back to Colors for SetPixels.
- A buffer of the bitmap that get's uploaded on Apply() but doesn't do any SetPixel() calls before that.

 

Sounds cool! Why you don't publish this on asset store?

 

Thanks, I'll post it in the Asset Store too so more people can find it. edit: It's submitted to Asset Store too, I'll update when it's available.

 

This has been accepted to the Asset Store so it's even easier to test it. It's a free asset.

I'm looking a drawline function that could support the line width...

 

Hi. I know this is an old thread, but I was wondering if it's possible to adapt the code to do outlines. Ex: You have an image composed of only 2 colours, and a black pixel is drawn wherever the colours change/meet. Thanks.
