Styling lines

[mm-spiio]

Hi there,

Is there a way to style a line? The only thing i could find is just the color of the line, but what about width and other properties one could set via CSS? is there any way?

For everyone here, the solution is the following

In BitmapFactory.common.js pass a parameter (e.g. strokeWidth) to the drawingMethod of choice. In my case drawline method looks like this:

bitmapClass.prototype.drawLine = function(start, end, color, **strokeWidth**) {
        start = toPoint2D(start);
        end = toPoint2D(end);
        color = toARGB(color);

        this._drawLine(start, end, color, **strokeWidth**);
        return this;
    };

BitmapFactory.ios.js

iOSImage.prototype._drawLine = function(start, end, color, **strokeWidth**) {
    color = this.__toIOSColor(color);

    this.__onImageContext(function(context, tag, oldImage) {
        CGContextSetRGBStrokeColor(context,
                                   color.r, color.g, color.b, color.a);

        CGContextSetLineWidth(context, **strokeWidth || 1.0**);

        CGContextMoveToPoint(context, start.x, start.y);
        CGContextAddLineToPoint(context,
                                end.x, end.y);

        CGContextStrokePath(context);
    });
};

BitmapFactory.android.js

AndroidBitmap.prototype._drawLine = function(start, end, color, **strokeWidth**) {
    this.__canvas.drawLine(start.x, start.y,
                           end.x, end.y,
                           this.__createPaint(color, **strokeWidth**));
};

AndroidBitmap.prototype.__createPaint = function(color, strokeWidth) {
    var paint = new android.graphics.Paint();
    **if(strokeWidth) paint.setStrokeWidth(strokeWidth);**
    if (!TypeUtils.isNullOrUndefined(color)) {
        paint.setARGB(color.a, color.r, color.g, color.b);
    }

    return paint;
};

index.d.ts

Update the methods definition you want

drawLine(start: IPoint2D | string, end: IPoint2D | string, color?: string | number | IArgb, strokeWidth?: string | number): IBitmap;

If / when i have time I'd make a pull request.
