Hi Hans,
Two bugs in figure export:
1. If one uses images without extension, then the generated
\jobname-images.css file does not contain any extensions; so no figures
are shown in the output. One possible fix is to change \dotagfigure in
back-ini.mkiv to
\appendtoks % we can have differently scaled images
\def\dotagfigure{\taggedctxcommand{settagfigure(,"\figurefullname","\figurefilepage",\number\dimexpr\figurewidth,\number\dimexpr\figureheight)}}%
\to \everyenableelements
% \figurefullname instead of \figurefileoriginal
2. What is the best way to handle multipage pdf images? I frequently
create a big pdf with many images and then use
\externalfigure[...][page=2]
I don't know if svg has support for multiple pages or not.
Aditya~

tricky ... \figurefullname can be the converted image (say that we wa
ask for an svg .. .it gets converted to pdf then) .. needs a bit of
thinking

The 'converter' program can filter the pages ... so we need to pass the
page number.
So we have 2 todo's

Page number is already passed. The filename conversion should make
use of it.
I think that the best solution is to allow the user to configure (using a
directive) the function that sets the new name for a pdf file, rather than
hardcoding an extension.
Also, can you add background-repeat: no-repeat; to imagetemplate.
local imagetemplate = [[
%s[id="%s"] {
display : block ;
background-image : url(%s) ;
background-size : 100%% auto ;
background-repeat:no-repeat;
width : %s ;
height : %s ;
}]]
Normally, this should not matter, but sometimes part of the image is
repeated due to rounding differences.

I used svg2pdf which converts all pages of a pdf to split svg files. But,
in the end, decided not to use svg images because most browsers do no
support svg inserted through css background-image. Instead, I am not
simply using png images and using imagemagics convert to convert pdf to
png.
