Thank you very much for taking time to reply Kovid, could you just please consider the following issues that I have:
1) the problem with the attached example is that the pictures do NOT fill the screen automatically (when tested on iPad3 it leaves big white margins and the picture shows up quite small). Is there any setting / code that I could use in order to be sure that the picture fills up the whole screen at least?
2) Is the SVG encapsulation idea not a good one or worth exploring?:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="100%"
viewBox="0 0 1536 2048" preserveAspectRatio="xMidYMid meet">
<image width="1536" height="2048" xlink:href="images/page01.jpeg" />
PS. I am a newcomer / dummy in epub, trying to learn by experimenting so please forgive me if I'm asking "stupid" questions!
All the best, Cristofer
