Project Name

Porting pushStyle(), popStyle(), and boolean() to Processing.js

Project Description

Processing.js remains incomplete as a port of Processing. Among the features still to be implemented are the functions pushStyle(), popStyle(), and boolean(). The first two functions automatically save style information for later retrieval and reuse. The last "converts" arguments into a boolean value.

This project seeks to implement those three functions. The repository may be found here.

Project Details

pushStyle() and popStyle()

The number of states saved is tracked by pushedStates.

pushStyle() calls curContext.save() and increments pushedStates by one.

popStyle() checks if there are any saved states via pushedStates. If there are none an error notice to the console or as a JavaScript alert, in an attempt to provide similar behaviour to Processing's implementation. If there are saved states, the function calls curContext.restore() and decrements pushedStates by one.

Related Mozilla bugs

  • #451165 - CanvasRenderingContext2D.fillStyle and strokeStyle accept invalid colours
    • pushStyle() and popStyle() use CanvasRenderingContext2D.save() and restore(). These functions save fillStyle and strokeStyle.
