@paola: sorry again.... copied the old verison... sorry. New version follows in a second.

Please find attached the version for the older firmware.

Personally I solved the path issue with "ln -s games /mnt/ext1/applications" in poterm.

hi Lonetech, i think I get the idea (though wouldn't be able to "meddle" with poterm: just mixed up "firmware" with "freeware"

), but at least in my case scribble is already in the games directory.

And incidentally, making me bind "last books" to a button caused me to find out how much more is hidden under that popup. Including Bluetooth toggling. Thanks!

@paola: The issue is that newer firmware put it in applications instead of games. So review's app looked in applications, and we had scribble in games, so it didn't find it. The ln command makes both names work the same, or you could make an applications directory and copy scribble.app there.

@paola, sorry, didn't ment to offend you, when I asked you if chose the right application. It was my fault. Mea culpa.

paola · 01-29-2011, 04:42 PM

@review: BINGO, it works! and please stop apologising, you are making me feel more an more guilty for free-riding on your work

@ LoneTech: thanks for the explanation, if I keep reading you guys in the end I am going to learn something!

ok, a breif update, as I have been playing around with it a bit. Sometimes the app does not start, I wonder whether it happens when there are no files in the "My pictures" directory.

At any rate, a simple way to organise different documents that you may care to annotate at different points in time is to have a huge "picture taking session" where you take images of all the pages in all the documents you want.

Then, linking the device to the pc, you reate various subdirectories of the "My pictures" directory on the device, one for each document, and put there the relative images.

Scribble automatically opens the sequence of pictures in the "My pictures" directory (does not see the subdirectories), so what you do is then copy the files you want to annotate from the relevant subdirectory into the "My Pictures" root. Disconnect, open scribble, and your document will be loaded. Once you are done, re-connect to the pc, move the annotated pictures back into their subdirectory, and move in the root another document, and so on.

If you have long papers it might take a while to take the pictures, but you will then be able to annotate - of course, you have to zoom at the level you like before taking the image, as scribble cannot zoom (as far as I can see).

Review, thanks a lot!

Thank you for the update. Yes, it might well be the case that if the My picture folder is completely empty that my app is not picking this up properly. I'm not going into the technical details here but the number of files is evaluated quite often while you run the program. The reason for this is that once you haven't added more annotations the program knows that you're done and quits. I might just add another conditional statement which picks up the case of an empty folder.
Thanks for reporting that.

1) I've looked at the source code of Xournal
2) ported the render engine mupdf successfully.
3) tried my own "scribble" application directly in djviewer

Now we reached a dead end at point 3:
Using the inofficial SDK, header and libraries I used the event handler which gives access to the coordinates of the pen on the screen. I've managed to get some hand written text on the screen. Within the djviewer application. The dead end is that we receive only about 50 events per second (or less). This makes it really slooooooooow to write and the delay is significant. This makes it virtually impossible to use.

I have to assume that scribble uses a new method to directly access a stream of coordinates and that it doesn't have to process each move event.

So that's where I'm at the moment.

Any thoughts or suggestions?

I've been trying to do some more involved stuff with the older SDKs, and the lack of documentation is making it very frustrating. Even just a single line explaining what each function does and a line for non-obvious parameters added to the header file would be a huge improvement. The inkdemo program is a big help, but it doesn't demo every function in the SDK. It would be good if you could pass this feedback up the line.

so, I'm trying to work out this annotation app, but it seems not working for me. my firmware is 2.0.5, so I think that's the problem. I cannot associate a button with "take a screenshot" 'cause I don't see the command :P but I can take a screenshot from the "last open books" button, so I wonder.... what's happens if I simply make a symlink from "my pictures" and "screens" directories? scribbles should find the screenshots, isn't it?
I'll make a try.

review · 03-21-2011, 04:22 PM

the filesystem is vfat so you probably won't be able to create a real symlink. the screenshot button can only be associated to the power button as far as I'm aware (speaking for the 2.0.4 but it should be pretty similar in 2.0.5).

preempalver · 03-21-2011, 05:10 PM

ow, vfat...

ok. I've done a soft symlink via rsh.app from "My pictures" directory to Screens, and it works.

$ ln -s "My pictures" Screens

so the screenshot app saves the screenshots directly in "My pictures", where scribbles works.
I suppose it means I cannot apply a reset, isn't it?
my expertise has come to an end, here

alas, I don't see "take a screenshot" anywhere in button association menus (for it's an italian customization made for IBS, I guess)
