April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.

Kamaelia: Paint

What is it?

Kamaelia: Paint is still very much in development (so this is my "vision" of what I want 'Paint' to become). Paint will be a powerful image editing tool, it will have native support of multiple core processors and put them all to good use :-). It should handle large volumes of images and have some simple tools for animations.

Where do I get it & install it?

developers

svn co
cd
python setup.py install

Linux
Something like:

*download .tar.gz
sudo python setup.py install
run

Windows
Something like:

download .exe
Install
Enjoy

Mac
Something like:

download .dmg
Install
Enjoy

Planned Schedule:

26/5 - Extend MagnaDoodle (Simple paint tool located in Sketches/DK) to implement the features of ProcessGraphline, with the end goal being having it running on a Backplane.
2/6 - Finish up working on MagnaDoodle / Start planning how the paint tool will be packaged. - Working on MagnaDoodle may take longer than expected however much of it will cross over to my Paint program so time spent here is also contributing to my main project.
9/6 - Consider what can be moved from the MagnaDoodle to Paint. Begin working on Paint, implementing mutual features from MagnaDoodle and extending them.
16/6 - Work on the painting canvas, look for the potential ways to implement a "layering" feature. nb. Something like what happens when you run MagnaDoodle with the Graphline.
23/6 - Finish up the canvas and start work a separate window for tools, such as Circles, lines various vector shapes. - note: this might take longer than 1 week
30/6 - Finish up the painting tools, and any additional work on the Canvas. I expect a colour selector to have been made in MagnaDoodle, however, it might be an idea to extend this and add more functionality to it.
7/7 - Hopefully now I have a fairly robust Paint program at this point. Now start to look at ways to extend this to various Animation methods.
14/7 - Work on Animator, try to reach a stage where I can have a "flick book" style animation see: http://en.wikipedia.org/wiki/Flip_book This style thing should be pretty easy.
21/7 - Look at more animation tools, perhaps modifying many frames of the animation at once.
28/7 - Consider encoding animations using something like dirac.
4/8 - Perhaps at this point look at implementing "given time" features such as simple video editing. Decoding dirac video's to a bunch of images for animation editing.
11/8 - Continue work on video editing features. Try to implement "Resume Session" feature.
18/8 - Wrap up the project and work on packaging it up.

15 May: Looked through code for MultiPipeline / Magnadoodle
22 May: Got 2 MagnaDoodle.py working together using ProcessPipeline(), also implemented simple scaling circle tool.
29 May: Got ProcessGraphline to clear one window when right click in the other (really cool :D) - this can be easily extended but encountered some problems with ProcessGraphline
5 June: I got the 2 MagnaDoodles talking, you can draw on the blue and it paints also on the Red. Abstracted away pygame events from the drawing for more flexibility.
12 June: Merged IRC Logger, got Tools2Apps ready for merge just got to resolve merging error. Moved to Paint from MagnaDoodle, started working on main project! Just started using an XYPad for paint selection
19 June: Recursive flood-fill algorithm for a "paint bucket fill" tool. Turned an XYPad into a nice colour selector and hooked that up to Kamaelia - Paint. Cleaned up code.
26 June: Non-recursive flood-fill working nicely lots better than last week, cleaned up code and added buttons for controling the tools. Started work on methods for layering
3 July: Layers (using pygame surfaces) are now working, little functionality currently but core is there. Added an Eraser tool and Eyedropper tool. PASSED MY EXAMS!
10 July: Functionality of layers, adding layers, switching between layers and changing the Alpha values (via slider bar) for each layer. Made a start using layers as a basis for Animations

Progress so far

Screenshots of my progress can be found here!

July 28th: I have restructured my code so it's worth making clear what I've changed. Previously I was working with a highly modified version of the XYPad for sliders and the colour selector. However that wasn't really the Kamaelia way to approach the problem, I had left it that way for too long and the longer I worked on the XYPad the more convoluted it became. IMO the Kamaelia way was to break that down into smaller components, this way the code would be reusable for anyone else. So I've broke the XYPad into the Slider, ColourSelector and ToolBox component. The colour selector and slider are both now just some pygame widgets and the ToolBox is the Paint specific code. Recently I've also worked on input and output of images, one bug I want to note (for my own benefit) is that when you save it will merge all layers to the background. Still looking to solve it but have wasted enough time on it for now :-).

Wishlist

Everyone has their favourite tools in paint programs like The Gimp and Photoshop, so if there's something you'd like to see in Kamaelia: Paint feel free to edit this list and add whatever you want. No promises! Oh, and don't add "Lens Flare" :P I'll go through this list and add priorities (5-1 low to high respectively) Thanks! Dave.
