<td>Font support for the Canvas element varies across browsers. FireFox currently has the best support, but still uses a pre-defined set of fonts. (Documentation to follow soon.) Good alternatives to the browser's Canvas-font functions are available: such as the <a href="http://bocoup.com/processing-js/docs/index.php?page=Cross-Browser%20Canvas%20Fonts">Glyph method</a>.

<td><p>Sets the current alignment for drawing text. The parameters LEFT, CENTER, and RIGHT set the display characteristics of the letters in
|
|
relation to the values for the <b>x</b> and <b>y</b> parameters of the <b>text()</b> function.</p>
|
|
<p>An optional second parameter can be used to vertically align the text. BASELINE is the default, and the vertical alignment will be reset to BASELINE
|
|
if the second parameter is not used. The TOP and CENTER parameters are straightforward. The BOTTOM parameter offsets the line based on the current <b>textDescent()</b>.
|
|
For multiple lines, the final line will be aligned to the bottom, with the previous lines appearing above it. </p>
|
|
<p>When using <b>text()</b> with width and height parameters, BASELINE is ignored, and treated as TOP. (Otherwise, text would by default draw outside the box, since BASELINE is the default setting.
|
|
BASELINE is not a useful drawing mode for text drawn in a rectangle.) </p>
|
|
<p>The vertical alignment is based on the value of <b>textAscent()</b>, which many fonts do not specify correctly. It may be necessary to use a hack and offset by a
|
|
few pixels by hand so that the offset looks correct. To do this as less of a hack, use some percentage of <b>textAscent()</b> or <b>textDescent()</b>
|
|
so that the hack works even if you change the size of the font.</p>
