Last change on this file since 2 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).

84 <!-- The HTML img element only supports the notion of content-area
85 scaling; it doesn't support the distinction between a
86 content-area and a viewport-area, so we have to make some
87 compromises.
88
89 1. If only the content-area is specified, everything is fine.
90 (If you ask for a three inch image, that's what you'll get.)
91
92 2. If only the viewport-area is provided:
93 - If scalefit=1, treat it as both the content-area and
94 the viewport-area. (If you ask for an image in a five inch
95 area, we'll make the image five inches to fill that area.)
96 - If scalefit=0, ignore the viewport-area specification.
97
98 Note: this is not quite the right semantic and has the additional
99 problem that it can result in anamorphic scaling, which scalefit
100 should never cause.
101
102 3. If both the content-area and the viewport-area is specified
103 on a graphic element, ignore the viewport-area.
104 (If you ask for a three inch image in a five inch area, we'll assume
105 it's better to give you a three inch image in an unspecified area
106 than a five inch image in a five inch area.
107
108 Relative units also cause problems. As a general rule, the stylesheets
109 are operating too early and too loosely coupled with the rendering engine
110 to know things like the current font size or the actual dimensions of
111 an image. Therefore:
112
113 1. We use a fixed size for pixels, $pixels.per.inch
114
115 2. We use a fixed size for "em"s, $points.per.em
116
117 Percentages are problematic. In the following discussion, we speak
118 of width and contentwidth, but the same issues apply to depth and
119 contentdepth
120
121 1. A width of 50% means "half of the available space for the image."
122 That's fine. But note that in HTML, this is a dynamic property and
123 the image size will vary if the browser window is resized.
124
125 2. A contentwidth of 50% means "half of the actual image width". But
126 the stylesheets have no way to assess the image's actual size. Treating
127 this as a width of 50% is one possibility, but it produces behavior
128 (dynamic scaling) that seems entirely out of character with the
129 meaning.
130
131 Instead, the stylesheets define a $nominal.image.width
132 and convert percentages to actual values based on that nominal size.
133
134 Scale can be problematic. Scale applies to the contentwidth, so
135 a scale of 50 when a contentwidth is not specified is analagous to a
136 width of 50%. (If a contentwidth is specified, the scaling factor can
137 be applied to that value and no problem exists.)
138
139 If scale is specified but contentwidth is not supplied, the
140 nominal.image.width is used to calculate a base size
141 for scaling.
142
143 Warning: as a consequence of these decisions, unless the aspect ratio
144 of your image happens to be exactly the same as (nominal width / nominal height),
145 specifying contentwidth="50%" and contentdepth="50%" is NOT going to
146 scale the way you expect (or really, the way it should).
147
148 Don't do that. In fact, a percentage value is not recommended for content
149 size at all. Use scale instead.
150
151 Finally, align and valign are troublesome. Horizontal alignment is now
152 supported by wrapping the image in a <div align="{@align}"> (in block
153 contexts!). I can't think of anything (practical) to do about vertical
154 alignment.
