I have tried to inform you about this before by replying to an old bug-report, but it seems that that did not work out well.
Hi Roland and others,
I have made a small modification to the djvu-image function so that it displays annotations. The code can be found
here (a small comment follows)
Although I had extended djvu.el already with some nice extra features in
djvu2, those extensions mainly relied on the usage of the external imagemagick command.
This
time however, I have used Emacs capability of drawing svg files. I have
simply embedded the ppm in an svg image and subsequently we can use
svg.el to draw annotations.
To test it you can just load the file after you loaded the original djvu.el and then open some djvu with annotations.
I think the annotation part is quite clean code, and it is really just a small modification.
Additionally in the section Keyboard annotation functionality I have added a quite fancy function to make highlights with the keyboard.
You can test it after loading the file by using the command djvu-keyboard-annot.
It is up to you if you also like to implement that. If you like to implement any of this in djvu.el, then I could make a patch.
Or you can just copy the code and do with it whatever you like.
Additionally I have a small question (to anyone receiving this mail)
I
wanted to keep the annotation draw functionality in a separate function
outside of the djvu-image function, but then I had to pass all the
local variabels,
Do you happen to know some (closure like?)
trick to pass the local variables while defining the function outside of
the djvu-image function (so without passing the variables explicitly as
arguments)?
I forgot to mention that that keyboard annotation function is meant to be handy for annotating directly from djvu-image-mode...
Thanks again!
