Lightbulb DJVU Viewer in Java on the iLiad

OK, all the iRex paging UI stuff is added in and working.

Next features to figure out how to handle are annotations and searching. With no TextArea the annotations weren't a slam dunk.

I also need to figure out where to store the current page number. I'm thinking the .mbp files the Mobipocket Viewer is using.

Next up, an installer. But tonight is my first wedding anniversary so it won't be tonight.

.mbp files are simple RIFF files so handling should be easy. I just never tried to find where Mobipocket stores the current page number (they probably store the file position and guess at the page number).

The way he mentions "tonight" implies a happy marriage. :-)

Yamp, have a nice night, Scotty. My parents have married on May 12th.
It would be cool to have a djvu viewer again.

Happy anniversary !
(I am married for almost 29 years. It keeps getting better each year for us. I wish the same for both of you!)

I am happy you came back to developing for the iLiad again.

Another happy anniversary! My husband and I will celebrate our 20th this summer.

For later: will the annotations be attached to the "page" or to a location in the text, sort of like stickies? I'm wondering how resizing fonts or changing orientation would affect the annotations.

Thank you everyone! We were kinda new to the whole anniversary thing but we had a good time!

For the non-Average Joe's out there, and you know whom you are, I attach the DJVU code. I've still got to craft the page save logic and an installer but you can get a peek now.

The javadjvu.jar and djvu.sh from the zip need to be copied to /home/intent and then (carefully) apply these hacks to er_registry.txt.

Code:
[USER_APPLICATIONS]
uaIDList=SHELL;BROWSER;IPDF;APABIMOBI;IMAGEVIEWER;SETUP;PROFILES;EBA;MOBIPOCKET;DJVU
[DJVU]
category=viewer
arguments=<FILENAME>
exec=/home/intent/djvu.sh
xResourceName=intent
channel=15
extensions=djvu;DJVU
[EXTENSION_INFO]
djvu=/usr/share/contentlister/Icon_mobipocket.png
DJVU=/usr/share/contentlister/Icon_mobipocket.png
I've been using the build.sh script and JDK 1.5.0_07 to build the source. There is no annotation support at present since there is not java.awt.TextArea on the iLiad.

I learned alot porting this hopefully you all will too. Enjoy!

For new firmware 2.11 (where er_registry.txt is replaced by /mnt/settings/registry/registry.xml) following additions to the registry.xml worked well for me (based on the er_registry.txt by scotty1024 and registry.xml advice from AdamB. on n00b thread):

Inserted within <applications>

<application type="JAVADJVU">
<appCategory>viewer</appCategory>
<execute>/home/intent/djvu.sh</execute>
<argMask>_FILENAME_</argMask>
<xResourceName>intent</xResourceName>
<ipcChannel>15</ipcChannel>
<supportFormat>
<extName>djvu</extName>
<extName>DJVU</extName>
</supportFormat>
<appIconPath/>
</application>


Inserted within <extensions>

<extensionInfo>
<associateApp>JAVADJVU</associateApp>
<extName>djvu</extName>
<extIcon>/usr/share/contentlister/Icon_mobipocket.png</extIcon>
</extensionInfo>

<extensionInfo>
<associateApp>JAVADJVU</associateApp>
<extName>DJVU</extName>
<extIcon>/usr/share/contentlister/Icon_mobipocket.png</extIcon>
</extensionInfo>


Hope this helps n00bs like me ...

(More gory details: using mrxvt [could have used emelfm too] copied registry.xml to /mnt/free/notes [or any other shared place], from there copied it to Linux PC [or Win, there notepad editor would do the work] after connecting iLiad to it via USB, edited it [using emacs, other text editors would do also] there and copied it back to iLiad notes folder. [Kept registry.xml.old just in case]. Within iLiad copied new registry.xml to /mnt/settings/registry again using mrxvt [emelfm can be used as well]. Rebooted iLiad. Happy reading DJVU textbooks now! Thanks to all who made this in the first place...

Here's a version that works on my iLiad with firmware 2.12.
Installation is the same as for the original version, i.e.:
- unzip djvu-0.1a.zip
- move javadjvu.jar and djvu.sh to /home/intent
- update the registry as indicated in dusanmal's post

This is my first attempt at programming for the iLiad, so I hope everything works OK.
I just took Scotty's version and did some minor changes to make it work, but I haven't tested it extensively.
