Am I right in understanding your Javascript asks the <canvas> widget to render some text in a particular font, size, and location, and what pixels are set, e.g. for anti-aliasing, are up to the browser's implementation? > If you zoom in using the *100%* menu, you'll notice you can't > scroll left or upwards.

Someone else already mentioned the probable area to look in, but https://stackoverflow.com/questions/11332608/understanding-html-5-canvas-scale-and-translate-order may also be useful if you're not used to affine transformations for 2D graphics. If you can multiply a 3×1 matrix by a 3×3 matrix then you should be able to figure it out. https://www.willamette.edu/~gorr/classes/GeneralGraphics/Transforms/transforms2d.htm looks like a reasonable intro from a quick skim. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
