Okay, I've been playing with this just now, and as far as the image goes, that looks fine, but I'm struggling a bit with the caption.
Re the SVG code you gave me before, Dale, the first part was as follows...
Code:
<svg xmlns="http://www.w3.org/2000/svg" height="100%" width="100%" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 2048 1600"
xmlns:xlink="http://www.w3.org/1999/xlink">
<image height="1536" width="2048" xlink:href="../Images/cranch1840-the_us_capitol.jpg" />
The caption seemed too close to the image, but by simply changing the height="1536" to height="1500", that seemed to solve that problem.
However, if possible I'd like to bump up the font size of the caption, too, which seems rather too tiny. In that regard, your code continues...
Code:
<text x="900" y="1550" font-size="40">The U.S. Capitol (1840)</text>
</svg>
I must be slow, because I don't understand that font-size bit at all. What would be nice if I could set it as a percentage, like the font sizes I use throughout the rest of the book, but I tried that and it doesn't work.
So I went digging in the wiki about SVG re "units"...
http://www.w3.org/TR/SVG11/coords.html#Units
...and all that does is confuse me even more! Oh, and changing the font size in that bit of code, above, to 60 (or whatever) does increase the size, but it doesn't keep it centered. I'm looking at the other figures you have for the x- and y-coordinates, and I don't understand how you came up with those numbers, i.e. the "math" behind it, relative to the size of the viewbox or whatever else. I'm sure the answer must be in the wiki there somewhere, but I don't even know where to begin to look (although "units" jumped out at me in the table of contents for the page, re the above).
Sorry to bug you about this -- my brain has just never been very good with this kind of thing. :/
