59 <!-- The HTML img element only supports the notion of content-area
60 scaling; it doesn't support the distinction between a
61 content-area and a viewport-area, so we have to make some
62 compromises.
63
64 1. If only the content-area is specified, everything is fine.
65 (If you ask for a three inch image, that's what you'll get.)
66
67 2. If only the viewport-area is provided:
68 - If scalefit=1, treat it as both the content-area and
69 the viewport-area. (If you ask for an image in a five inch
70 area, we'll make the image five inches to fill that area.)
71 - If scalefit=0, ignore the viewport-area specification.
72
73 Note: this is not quite the right semantic and has the additional
74 problem that it can result in anamorphic scaling, which scalefit
75 should never cause.
76
77 3. If both the content-area and the viewport-area is specified
78 on a graphic element, ignore the viewport-area.
79 (If you ask for a three inch image in a five inch area, we'll assume
80 it's better to give you a three inch image in an unspecified area
81 than a five inch image in a five inch area.
82
83 Relative units also cause problems. As a general rule, the stylesheets
84 are operating too early and too loosely coupled with the rendering engine
85 to know things like the current font size or the actual dimensions of
86 an image. Therefore:
87
88 1. We use a fixed size for pixels, $pixels.per.inch
89
90 2. We use a fixed size for "em"s, $points.per.em
91
92 Percentages are problematic. In the following discussion, we speak
93 of width and contentwidth, but the same issues apply to depth and
94 contentdepth
95
96 1. A width of 50% means "half of the available space for the image."
97 That's fine. But note that in HTML, this is a dynamic property and
98 the image size will vary if the browser window is resized.
99
100 2. A contentwidth of 50% means "half of the actual image width". But
101 the stylesheets have no way to assess the image's actual size. Treating
102 this as a width of 50% is one possibility, but it produces behavior
103 (dynamic scaling) that seems entirely out of character with the
104 meaning.
105
106 Instead, the stylesheets define a $nominal.image.width
107 and convert percentages to actual values based on that nominal size.
108
109 Scale can be problematic. Scale applies to the contentwidth, so
110 a scale of 50 when a contentwidth is not specified is analagous to a
111 width of 50%. (If a contentwidth is specified, the scaling factor can
112 be applied to that value and no problem exists.)
113
114 If scale is specified but contentwidth is not supplied, the
115 nominal.image.width is used to calculate a base size
116 for scaling.
117
118 Warning: as a consequence of these decisions, unless the aspect ratio
119 of your image happens to be exactly the same as (nominal width / nominal height),
120 specifying contentwidth="50%" and contentdepth="50%" is NOT going to
121 scale the way you expect (or really, the way it should).
122
123 Don't do that. In fact, a percentage value is not recommended for content
124 size at all. Use scale instead.
125
126 Finally, align and valign are troublesome. Horizontal alignment is now
127 supported by wrapping the image in a <div align="{@align}"> (in block
128 contexts!). I can't think of anything (practical) to do about vertical
129 alignment.
