Last change on this file was 2, checked in by jkacer, 18 years ago

Added all DocBook Framework stuff:

  • DocBook DTD
  • Transformation software FOP 0.20.5 and Saxon 6
  • XSL styles
  • Rexx scripts

Also added some WarpIN-related stuff for creation of WarpIN installation packages.
This state corresponds to version 1.0.0 from November 2005, just slightly modified to carry versioning information (Rexx scripts).

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