Image.drawRect()

Draws a rectangle onto an image.

Syntax
imageObject.drawRect(xNumber, yNumber, widthNumber, heightNumber)

The rectangle's dimensions are calculated from the xNumber- and yNumber-offset (ie. from the top left corner of the image as upper left reference point) to xNumber + widthNumber and yNumber + heightNumber as lower right reference point.

Example
var img = new Image("http://helma.org/images/originalgif");
res.write('<img src="/images/original.gif">');



img.setColor(204, 0, 0);
img.drawRect(57, 8, 46, 20);
img.saveAs("/www/images/processed.gif");
res.write('<img src="/images/processed.gif">');
