Andy, it is not so easy. I have found several cases with different header for example (prova1.pdf Attachment 83659):

B0 04 11 06

another example (test_cross.pdf Attachment 83660):
6C 04 40 06

I should change header with an hex editor (editing in 0x0c, 0x04, 0x40, 0x06) and put in JBC to see what will happen.

I have noticed that if I open prova1.pdf width Gimp and I set width=1200 (0x4b0, then I get height=1553 (0x611) and the same thing for test_corss.pdf.

Conclusion: 2 words in header indicate the size of page in a 1200x1600 screen (respectiong original aspect ratio)

Note: I'll edit jcrosssketch to ignore header in import but in export there would be some trouble because it cannot know the original page sizes

Ah, now that's interesting. I wonder what it is?

Editi jCrossSketch sfilter/Jbc.java

...
defDim[0] = 1200; defDim[1] = 1600;
...
in.read(header); // the headder contains the image maxwith
pW = ((int)(header[1]) << 8) | ((int)header[0] & 0x00ff);
pH = ((int)(header[2]) << 8) | ((int)header[3] & 0x00ff);
if (pW <= defDim[0] && pH <= defDim[1]) {
System.err.println("ignore file "+file);
} else {

Ok, fews minutes and I will upload the 0.3 version with the fixes discussed above.

The export is ok, the import not because I have to find a way to calculate the exact heder.

Anyway play with my JBC I used the test_cross.pdf:


Well, now:

• open Jarnal
• click on File->Open as Background
• Select test_cross.pdf
• Save file as test_cross.jaj

Using jCrossSketch:

• Input type JBC
• dir name path to "test_cross" folder with scribbles
• Ouput type JAJ
• file output: test_cross.jaj (saved before with Jarnal)

Opening the test_corss.jaj with Jarnal:


Crosses are not in line!!! calibrate needed. So I play aroud with "resize" function of jCrossSkecth and I found the right values (I don't remeber now what they are) and ecco qua! (here you are!):


Edit: The Version 0.3 is now on-line on sourceforge.net

Nice! Can jarnal save out the resultant PDF?

Edit I can answer my own question - yes Jarnal can save as a PDF file. Looks to me like we should be thinking about adding a JBC import function to Jarnal if possible.

I loved Jarnal for the first time I discovered it :-)
I wrote to the author about 4 years ago to suggest the idea to integrate the JcrossSketch framework into Jarnal. But I had no luck

[paperwastage]

Java program, inserts scribble into a pdf file using iText

Jetbook-color-pdf-scribble v0.1

UNTESTED (still haven't updated my jetbook color to the latest firmware yet ....

This is entirely command line for now. look at the README on how to use the program

(sometimes iText doesn't like malformed PDF and crashes.....)

(most of the logic is inside PDFEditor.java, so it shouldn't be hard to integrate this into JCrossSketch/Jarnal if need be)


----------------------
Changes
v0.2
Allowed the second argument to be a directory containing scribble files

v0.1
Inital release (untested with Jetbook Color Scribble files yet)

Since a friend requested me to show him enTourage edge's Journal capabilities (e-ink side), you may find here something inspirational for developing JBC's scribbling.

http://www.box.com/s/j7g6eod1d9alscsbdktr

ESJ file is the journal.
PDF is the same file, exported from the Journal.
I added to the folder a random *.esa file which should contain a small annotation made over an epub file.

These files are similar to Xournal ones. Copy-paste from here: https://www.mobileread.com/forums/sho...urnal+location

These files appear to be xournal files, but you cannot open them with xournal. You need to do the following first:
copy foo.esj to another machine with xournal installed.
mv foo.esj foo.gz
unzip foo.gz

Then open foo with text editor, and replace line
<page width="396.00" height="540.00" tabname="">
with line
<page width="396.00" height="540.00">

Then do:
gzip foo
mv foo.gz foo.xoj

The resulting foo.xoj file can then be opened with xournal.
--

There's another difference - xournal doesn't understand the "landscape" or "activity" (calendar) background style, so instead of just

zcat $infile | sed -e 's/\(^.*<page .*\) tabname.*$/\1>/' | gzip -c > $outfile

you need to do:

zcat $infile | sed -e 's/\(^.*<page .*\) tabname.*$/\1>/' -e 's/landscape/plain/' *-e 's/activity/plain/'| gzip -c > $outfile

A user developed an app to convert these annotations with MS OneNote: http://edgesync.codeplex.com/

Lorenzo,
in 2008 when I developed the first release of jCrossSketch I choose to support Jarnal because Xournal was (I think even now) not cross-platform.

I like the WORA slogan very much

Anyway one could surely extend JCS writing an ad-hoc class for Xournal.

No one will use JBC simply to take notes, but if you think to use Jetbook Color as block notes, you may take some advantages using this file as template.

Hi everyone,
The new realease 0.5 are now on sourceforge.net ready for the download. Tris version fixed a lot of things about Jetbook Color scribble class. Now you can use it stable with jarnal to merge scribbles and PDF in new PDF document without do the manual resizing.
There is only a problem dealing with multiple size of the pages in the same PDF document

Nice! I already started use it for my records. You can send this file to Ectaco and offer them preload it with new JBC frmware version .

[mod186k1]

Kriss,
I feel Stylus in JBC respond with great precision. I experienced an Wacom based stylus input on iLiad before, but it not comparable with this. It's a pity that sometime stylus input losts the track (before "disk" icon appears). What is your experience?

Would you mind giving some simple step by step instructions how to get a PDF and the matching jetBook Color scribbles merged into a 3rd file (a new PDF or jaj file)? I'm getting lost somewhere in amongst jCrossSketch and Jarnal, scribble files, PDFs and jaj files.

Andrew

[mod186k1]

Yes, sure.
1) run Jarnal
2) click on File->Open as Background
3) select PDF file and then click on "open" (eg. "foo.pdf")
4) click on File->Save and save file as for example "foo.jaj"

These steps are needs to create a sort of "template". Then

5) open the PDF file on your JBC and scribble what you like
6) close the file in JBC
7) on Pc launch jCrossSketch
8) Input: type=JBC and with "Browse" select the JBC directory contains the scribble (It would be .jetbook/foo.pdf)
9) Output: type=JAJ and with "Browse" select "foo.jaj" previously saved (step 4)
10) Click in "Run filter" and it's all!

now jCrossSketch overwrite "foo.jaj" so if you will open it you will see PDF+Scribble. To export this in a new PDF you have simply click on File->Export->Export as PDF

Please report me if you have success or not
