Scaling graphics
Does anyone have or can point to ePub 2 code that will scale bitmap and SVG graphics when the font size is changed? Thanks.

If the image is inline it will normally scale. This is the only case I know of.

I use em for height and width in graphics for initials. That makes them scale with the text.

Code:
<div class="lettrine">
    <svg xmlns="http://www.w3.org/2000/svg" height="8em" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 400 402" width="8em" xmlns:xlink="http://www.w3.org/1999/xlink"><image width="400" height="402" xlink:href="../Images/initial-d.png"/></svg>
  </div>
Code:
.lettrine {float: left;	margin: 1.1em 0.5em -0.1em 0;}

Way back in 2013, we discussed this when someone wanted to put the "Apple" symbol in their EPUB:

Apple symbol and other special characters in ePub

There are sample EPUBs with scaling images and SVGs with font size.

RbnJrg has also written quite a bit on SVGs with code examples. If you do a search for "RbnJrg SVG", you should be able to come across many of his examples (Dropcaps, Scaling Tables, Images with Captions, [...]).
