Moshu's Canvas Library
Description
This is an attempt to vectorialize the CANVAS element. The library transforms working with pixels into working with objects.
This is the 4'th version of this library i believe. At each iteration i found issues with my initial design, and had to re-model it.
Inductively we can conclude this will also change, and hopefully improved, as long as i maintain interest in playing with the CANVAS.
One can find the previous iterations here:
Iteration 1
Iteration 2
Iteration 3
Characteristics
- Lightweight
- Independant - does not use other libraries
- Cross browser - it seems to work on all modern browsers
Shapes
All supported shapes at this time are polygon based. This is due to problems with determining collisions of type circle-polygon, circle-image, polygon-image, image-image, etc.
Supported shapes
- Polygon - base polygon constructed by providing the array of all vertices
Special polygon derivations:
- RegullarPolygon Can create a regular polygon (polygon with all sides equal), with any number of vertices. At the extreme we can create a polygon based circle with this.
- Line
- Triangle
- Rectangle
- Image We support image, but only when approximated to a polygon - namely the containing rectangle
