| <para>The HTML <tag>img</tag> 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> |
