Feature request: use depth and width from <imagedata>

[Steinar Bang]

I would like db2latex to make use of any depth and/or width attributes
found on <imageobject> elements, to do scaling on the included image.

Some of my documents contain images that are shown full size in HTML,
but have been scaled down in PDF, eg.:

<mediaobject>
<imageobject role="html">
<imagedata fileref="img/test.png" format="PNG"/>
</imageobject>
<imageobject role="fo">
<imagedata fileref="img/test.png" format="PNG" depth="6cm" scalefit="1"/>
</imageobject>
</mediaobject>

The db2latex XSL style sheets does not make use of the depth and width
attributes of <imagedata>, so it isn't enough to make db2latex use the
fo <imageobject>.

I have to create an extra <imageobject> for use by db2latex, in each
<mediaobject>, eg.:

<mediaobject>
<imageobject role="html">
<imagedata fileref="img/test.png" format="PNG"/>
</imageobject>
<imageobject role="fo">
<imagedata fileref="img/test.png" format="PNG" depth="6cm" scalefit="1"/>
</imageobject>
<imageobject role="latex">
<imagedata scale="25" fileref="img/test.png" format="PNG"/>
</imageobject>
</mediaobject>

I also have to figure out a suitable scaling factor for each image,
by trial and error, instead of scaling the image to the expected
size.

DB2LaTeX does honour the width attribute (but depth support was missing).

It may be that nobody else uses depth? :-)

I used it by mistake. I meant to use width, and when I figured out
what I had done wrong, all images had already been scaled to a
suitable size for printing, and I just let it be.
