I encounter lots of problems while trying to write some json prototype styled functions, and specially with referencing mgraphics across prototyped functions.

Maybe it's a problem of javascript syntax and comes from me, but look at the code :

width = this.box.rect[2] - this.box.rect[0];

height = this.box.rect[3] - this.box.rect[1];

if (columns === undefined || columns > 32 || columns < 1) {

if (lines === undefined || lines > 32 || lines < 1) {

var background_color = [0.1, 0.1, 0.1, 1.0];

this.context.set_source_rgba(background_color);

this.context.rectangle(0,0,width,height);

this.context.move_to((i + 0.5)*this.step_size, 0);

this.context.line_to((i + 0.5)*this.step_size, height);

this.context.move_to(0, (i + 0.5)*this.step_size);

this.context.line_to(width, (i + 0.5)*this.step_size);

else this.step_size = height/this.columns;

var matrix = new grid (jsarguments[1],jsarguments[2], max);

max window tell me that max javascript parser doesn't recognise calls to mgraphics (written inside the draw function) as functions ....

This must be a referencing error of my own, but is it possible to put mgraphics context into a var and pass it as arguments to functions ?

mgraphics.init();
var max = mgraphics;
max.relative_coords = 0;
max.autofill = 0;

width = this.box.rect[2] - this.box.rect[0];
height = this.box.rect[3] - this.box.rect[1];

    this.columns = columns;
    if (columns === undefined || columns > 32 || columns < 1) {
        this.columns = 4;
    }

    this.lines = lines;
    if (lines === undefined || lines > 32 || lines < 1) {
        this.lines = 4;
    } 

    this.draw();
    this.process_amount();
    this.step_size;
}

    draw: function() {
        var background_color = [0.1, 0.1, 0.1, 1.0];
        var color = [0.7, 0.7, 0.7, 1.0];
        var thickness = 1;

        this.context.set_source_rgba(background_color);
        this.context.rectangle(0,0,width,height);
        this.context.fill();
        this.context.set_source_rgba(color);
        this.context.set_line_width(thickness);
        this.context.set_line_cap("round");
        this.context.set_line_join("round"); 

        for(i=0;i
            this.context.move_to((i + 0.5)*this.step_size, 0);
            this.context.line_to((i + 0.5)*this.step_size, height);
        } 

        for(i=0;i
            this.context.move_to(0, (i + 0.5)*this.step_size);
            this.context.line_to(width, (i + 0.5)*this.step_size);
        }
        this.context.fill();
    },

        if (this.columns > this.lines){
            this.step_size = width/this.columns;
        }
        else this.step_size = height/this.columns;
    }    

function bang()
{
    mgraphics.redraw();
}

matrix.process_amount();
matrix.draw();
bang();

This must be a referencing error of my own, but is it possible to put mgraphics context into a var and pass it as arguments to functions ?
