Only after that conversion you can compare these screenshots accurately as they would look on-screen.

Indeed, as it was already told in other thread, the Xfvdev server does not suport any intermediate between 8 bits and 1 bit (contrary to "specification" in the man page), so here iRex is doing the best possible approach: go with 8, and mod it out in the driver or in the hardware.

Many thanks to Antartica for his patience with me in getting his tool chain setup. He helped make this possible.

You did it once again Scotty!

I don't really know what idjvu is all about, but congrats anyway...I'm pretty sure that those who own djvu files will be very happy to hear of your success...

Thanks!

I must admit I only have the one DJVU file myself!

Mike Kostousov · 11-01-2006, 10:17 PM

Scotty, where can I get your idjvu?

scotty1024 · 11-01-2006, 10:38 PM

idjvu is up on the MR project site. I've included the er_registry.txt snippet to activate it.

I was just happy to get it to link, run and display today. No panning, no zooming, and for now it always goes to page 1 on startup.

Things are still a bit rough with contentLister. It doesn't make you a manifest.xml, which is why I'm forcing the page to 1. And the icon is the X file icon but if you click on it idjvu will launch.

Please edit your /mnt/settings/er_registry.txt very carefully!

The idjvu application won't brick your iLiad but installing the settings into er_registry.txt could. Please make sure you have your life line shell ready to go.

Let's please be careful out there.

Mike Kostousov · 11-01-2006, 11:25 PM

Scotty, thanks! Very good job. I was doing idjvu also, but stoped after you published screenshots

On holidays I can help you with code, if you upload sources. Now, it works very good. djvu - is good format, and some times it is better to have djvu instead pdf, because some of pdf is really complisert and takes very much time to render.

scotty1024 · 11-02-2006, 12:32 AM

This is the 3rd re-write from ipdf scratch and I did it quickly to see if I could get it to link. I need to go back through the code and rename everything to DJVU and turn the pan and rotate code back on. I'll post the source after that.

In the mean time enjoy the binary. It has extra speed from direct writes to /dev/fb0, by passing the X server entirely.

Thanks for the compliments. But it's always a honour to assist a hard-worker as you ;-).

Good job :-D

I heard back from iRex regarding hooking idjvu into ContentLister.

ContentLister is hard coded internally.

So I need to extend idjvu to do the manifest.xml creation trick. Nothing at all I can do about the icon ContentLister shows but on the bright side, at least ContentLister launches idjvu even if it doesn't know what it is.

Another good piece of news, I've compiled Poppler and it comes out reasonably close in size to iRex's.

I've gotten zero cooperation out of iRex on Poppler so I'm out on a limb on this one.

I've identified the slow Jack Rabbit Benchmark performance as being a bit of code in Poppler with a note hanging from it saying something similar to: "Please don't make me optimize this, let's use libtiff instead..."

I've compiled libtiff and I'm looking at how many of its nicely written decoders I can hook into Poppler to enhance it.

Antartica's tool chain with scratchbox rulez! Highly recommended update over iRex's tool chain.

scotty1024 · 11-03-2006, 11:41 AM

It is my unhappy task to let you know that I've decided to kill idjvu.

ContentLister simply isn't setup to support it and I'm not going to re-invent the wheel to do all the stuff ContentLister is doing to create the manifest.xml.

So what I am going to be doing this weekend is re-factoring ipdf.

I'm going to make ipdf into a pluggable framework into which viewers for other file formats can be installed, and leverage ipdf as the UI for paging, rotating, zooming, and getting manifest.xml's built via ContentLister.

My plan is to release 3 viewers with the new ipdf.

1. wrapper for Poppler e.g PDF support
2. wrapper for DJVULibre e.g. DJVU support
3. wrapper for my RTF parser e.g. Baen RTF ebook support (and yes, I'll still be doing the read direct from ZIP trick.)

The ipdf will use direct to screen memory page transfers with an X window popup place holder for it (so X doesn't get confused.) It will have a full 8 bit path for crisp text.

Support for improved decoding time and error dispersion of images will be in the next release of the Poppler wrapper (sorry, only so many hours this weekend.)
