Project Name
Porting Processing to Processing.js
Project Description
Processing.js remains incomplete as a port of Processing. The following functions are targeted:
- pushStyle()
- popStyle()
- boolean()
- strokeCap()
- strokeJoin()
- text() (bug fix)
- min() (bug fix)
- max() (bug fix)

Project Details
pushStyle() and popStyle()
- The number of states saved is tracked by pushedStates.
- pushStyle() calls curContext.save() and increments pushedStates by one.
- Excess pops are ignored.
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.
boolean()
- Non-zero numeric values become true
- Bytes (0's and 1's) are interpreted as numeric values.
- null and undefine become false.
- Boolean arguments are returned as themselves.
strokeCap()
- Modifies context.lineCap.
- ROUND -> context.lineCap="round";
- SQUARE -> context.lineCap="butt";
- PROJECT -> context.lineCap="square";
- Processing default (ROUND) set in function init.
- function size modified to respect previous settings.
- Used to recreate context and reset settings, which overwrote the desired default.
strokeJoin()
text()
- Partially implementation missing ability to take int, float, double, and byte arguments.
- float and doubles rounded to thousandths digit.
- .5 rounds down rather than up.
