Package: tex4ht
Version: 20090521-1
Severity: normal

	<img src="manual-web0x.png" alt="PIC" class="graphics"
	 width="888.31874pt" height="630.355pt"><!--tex4ht:graphics
	 name="manual-web0x.png" src="img/home.eps" -->

The actual image size is 885x628 pixels. First, HTML does not use points
at all; see §6.6 [0]. Second, the width and height attributes are
defined to take type "length" (see §13.7.1 [1]) which is defined in §6.6
as either an integer (number of pixels) or a percentage.

Finally, even if we were to ignore the HTML standard's prohibition of
points, and import CSS's use of them, CSS uses PostScript (1/72")
points, but TeX (and tex4ht) are using TeX points (1/72.27"). Also, it
assumes a 72dpi[2] display whereas most modern displays are closer to
100dpi, so expect some serious scaling[3] — of a bitmap image.

[1]: http://www.w3.org/TR/html4/struct/objects.html#h-13.7.1
[2]: This can be seen from doing a little math on the size of the image
     and the point size tex4ht is spewing out:
         888.31874 × (1⁄72.27) ÷ (1⁄72) ≅ 885
[3]: 888.31874 PostScript points ≅ 1234 pixels @ 100 ppi. So the image
     will be scaled up almost 40%, gaining either a good deal of
     jaggedness or blurryness.
