If only the content-area is specified, everything is fine. + (If you ask for a three inch image, that's what you'll get.) + + 2. If only the viewport-area is provided: + - If scalefit=1, treat it as both the content-area and + the viewport-area. (If you ask for an image in a five inch + area, we'll make the image five inches to fill that area.) + - If scalefit=0, ignore the viewport-area specification. + + Note: this is not quite the right semantic and has the additional + problem that it can result in anamorphic scaling, which scalefit + should never cause. + + 3. If both the content-area and the viewport-area is specified + on a graphic element, ignore the viewport-area. + (If you ask for a three inch image in a five inch area, we'll assume + it's better to give you a three inch image in an unspecified area + than a five inch image in a five inch area. + + Relative units also cause problems. As a general rule, the stylesheets + are operating too early and too loosely coupled with the rendering engine + to know things like the current font size or the actual dimensions of + an image. Therefore: + + 1. We use a fixed size for pixels, $pixels.per.inch + + 2. We use a fixed size for "em"s, $points.per.em + + Percentages are problematic. In the following discussion, we speak + of width and contentwidth, but the same issues apply to depth and + contentdepth + + 1. A width of 50% means "half of the available space for the image." + That's fine. But note that in HTML, this is a dynamic property and + the image size will vary if the browser window is resized. + + 2. A contentwidth of 50% means "half of the actual image width". But + the stylesheets have no way to assess the image's actual size. Treating + this as a width of 50% is one possibility, but it produces behavior + (dynamic scaling) that seems entirely out of character with the + meaning. + + Instead, the stylesheets define a $nominal.image.width + and convert percentages to actual values based on that nominal size. + + Scale can be problematic. Scale applies to the contentwidth, so + a scale of 50 when a contentwidth is not specified is analagous to a + width of 50%. (If a contentwidth is specified, the scaling factor can + be applied to that value and no problem exists.) + + If scale is specified but contentwidth is not supplied, the + nominal.image.width is used to calculate a base size + for scaling. + + Warning: as a consequence of these decisions, unless the aspect ratio + of your image happens to be exactly the same as (nominal width / nominal height), + specifying contentwidth="50%" and contentdepth="50%" is NOT going to + scale the way you expect (or really, the way it should). + + Don't do that. In fact, a percentage value is not recommended for content + size at all. Use scale instead. + + Finally, align and valign are troublesome. Horizontal alignment is now + supported by wrapping the image in a <div align="{@align}"> (in block + contexts!).
