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. |
