I've discovered a slight problem. The new xournal port works very well at updating the screenas you write, for the first page. However, when you choos another page, for some reason, the display is no linger updated as you write. You have to force a screen refresh (as was originally the case). This only appears to happen when you "turn a page".

Summary, Page 1 okay, stylus and display update together, 2nd and subsequen pages, no screen update until you force it.

This is not due (only) to the Xournal software, I have just experienced a complete hang of my DR during the annotation of a simple PDF. It may be that installing Xournal has a side-effect, however this also happens in other situations outside Xournal.

I hope this is a useful finding,

yes, for me it works. the problem is that the screen refresh is every 2 seconds or so but it is not 1.6 firmware issue.

yingwu,
It doesn't in the DR version. Not all the functionality is supported. I think that was mentioned in the beginning.

It would be nice to have a save as pdf supported as there is no Xournal port for MAC's so I have to leave things in the native format at present which is a bit frustrating at times.

I am looking into porting the missing libraries for pdf-printing, but get the following problem:

/usr/lib/libart_lgpl_2.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status

For some reason it tries to look for libart_lgpl_2.so in /usr/lib i.s.o. in to poky/.../usr/lib/ . It seems that something is not correctly installed in my environment. Xournal also needs libart and builds fine. Is there any trick I should know related to libtool?

print to pdf shouldn't be that hard

Print to PDF shouldn't be that hard to port to iRex, if you're willing to discard TrueType text objects in the annotations. Xournal does most of its PDF export completely by hand without using any libraries -- the only exception is extracting subfonts from the TrueType system fonts for inclusion into the exported PDF, and that's presumably not a useful feature on iRex.

The bad news is that the two different printing systems (via libgnomeprint for printing to printers, and "by hand" for exporting PDF) share the same source code file, so you'll have to remove the bad parts by hand. In xo-print.c, you'll want to keep the function print_to_pdf() and everything it calls, but discard all the code for printing via libgnomeprint. In the 0.4.2.1 source code, you roughly want to keep lines 1-1400 of xo-print.c and discard everything after that. You'll still have some trouble with the functions new_pdffont() and embed_pdffont() -- one option is to also compile in sft.c from the source code of libgnomeprint. The more brutal option is to remove these two functions, and also remove what's inside
else if (item->type == ITEM_TEXT) {...}
(lines 1072 to end of pdf_draw_page()). (This will exclude text items from being exported, but will simplify your life). The Right Way is somewhere in between, but I'd certainly understand if you're not willing to look too closely at that portion of the code.

Contact me at (myusername)@math.mit.edu if you need more info / advice about how the code works. I don't have much time to spare and have no idea how iRex works so I won't get involved in details, but I'm always happy to clarify questions about the code.

Denis.

You can also look at the source code of 0.3.3 for how PDF export used to work before I added in support for text annotations. If you diff xo-print.c from 0.3.3 to 0.4.2.1, it splits pretty neatly between fairly small (but sometimes important) bugfixes/updates, which you should keep, and text object support, which you may want to discard if it's too hard to compile in. Once again you'll want to get rid of all the stuff about libgnomeprint printing and keep only the PDF printing.

Being able to save scribbles to a PDF file would be a most welcome function.

@ auroux:
Thanks for the info, I did not look into the code that well, but your suggestions will be very helpfull in getting pdf-printing working.
At this moment some 'external conditions' (=sun+beer) keep me away from my computer, so I do not know when I have time to look at it.
Thanks again for the info/advice that you are willing to give. (I might need it.)

I tried the 'easy' way, it has pdf-export support, but no font support.
The instructions from auroux were very accurate so it compiled and worked very quickly.

But like I said, it does not support text!

Select File-> Export to PDF, the very anoying file selector dialog will start.

That's it.

I reverted back for the refresh to the 'text-label-refresh' which will give a delay of about 2 seconds. Grimulkan did not yet publish his last code, and this 'version' of refresh seems the safest to me.

The zip-file is an 'update', so if you did not install xournal on your DR (or updated to v1.6 which removed the installed version ...!) go the the first mail in this thread and follow the instructions the install that version. After that install this version (after unzipping the zip-file to the root of your SD-card you will have an Install-directory in the Programs-directory. Open it and click on InstallXournalPdfV1 and the new version will overwrite the old one.)

I hope to make improvements when needed, please let me know.
