<para>The HTML <sgmltag>img</sgmltag> element only supports the notion
|
|
of content-area scaling; it doesn't support the distinction between a
|
|
content-area and a viewport-area, so we have to make some compromises.</para>
|
|
|
|
<para>If <parameter>make.graphic.viewport</parameter> is non-zero, a table
|
|
will be used to frame the image. This creates an effective viewport-area.
|
|
</para>
|
|
|
|
<para>Tables and alignment don't work together, so this parameter is ignored
|
|
if alignment is specified on an image.</para>
