p.s.: To simplify coping with changing font sizes, it probably makes
sense to add an "align" parameter (left|center|right
top|center|baseline|bottom) to the drawString call...

Hi,
I would like to second the drawString() request.
It makes sense to have a simple API, but it should be balanced with
application simplicity and readability to some extent. Doing CSS black
magic to overlay text and a Canvas object just seems inadequate for
something like axis labeling.
As noted earlier by somebody else (did not find the mail...), we would
also need a simple Font object, but the minimum requirements seem
rather simple:
Font Canvas.createFont(String cssFontProperties);
Canvas.setFont(Font font) // set current font
Canvas.drawString(int x, int y, String text);
Font Canvas.getFont() // current font
int Font.stringWidth(String s);
int Font.getHeight(); // includes leading
int Font.getBaselinePosition();
int Font.getAscent();
int Font.getDescent();
Best regards

I believe that some people's reason for not wanting to add it was
because of Accessibility concerns.
Although normal text in a webpage... or even a text image (with
the "alt" attribute filled in properly) could be "read" by a
person with disabilities, text embedded in the canvas element
could not.
Perhaps people need to think about how to add Accessibility to the
canvas while allowing a "drawString" procedure.
Well a drawString method in canvas can be used for drawing the axis
labels or values on a dinamic javascript graphic, but is non sense an
aural reader read it, theres no way (yet) to read an image to a
blinded people, there are cases where is imposible the accessibility,
is imposible for a blind to play video games, and accessibility dont
stop the video games creation. In the case of images or the canvas
the alt attribute could do the job.
See ya
