Tutorials

Here are several tutorials published by Opera Software, which are strongly related to PaintWeb:

• HTML 5 canvas - the basics. This article provides an introduction to the basics of using the new Canvas element.

• Creating an HTML 5 canvas painting application. This article starts from the very beginning of PaintWeb - you will learn how to start the development of a paint tool.

• Keyboard accessibility in Web applications is a three-parts article in which I focus on making the basic paint application keyboard accessible. I continue from the final example provided in the previous article I wrote on how to create your own paint application.
1. Keyboard shortcuts for tool activation - how to implement keyboard shortcuts per drawing tool.
2. Drawing with the keyboard - the implementation of the MouseKeys extension for PaintWeb. This extension allows users to draw with the keyboard, without any pointing device.
3. Cross-browser compatibility - how you can implement a cross-browser compatibility layer for handling DOM keyboard events.

Other articles

Here's a list of other articles published about PaintWeb which detail technical aspects. These articles are not documentation per-se, but they provide details otherwise unknown.

• PaintWeb performance work did during GSOC 2009.

• Canvas text rendering. This article details the work I did on the text tool for PaintWeb, and the problems I got into with Opera and older Firefox versions.

• PaintWeb packaging results. This article details the work I did on PaintWeb packaging - it provides the numbers of files and the numbers of kilobytes before and after packaging. It's worth to know why packaging is important.

Further documentation will become available.
