Kindle DX and djvu format

[darkstar]

I have alot of djvu format books, using the STDU converter ( with autocrop enabled) I have converted many of them to PDF and viewed them on my DX. I am quite pleased the the results, the text and equations look quite sharp ( as good as the djvu document viewed on my computer). The only downsides are the STDU converter is $30, and the resulting PDF file seems to be 2 to 4 times larger then the djvu file.

One of the reasons the project is using DJVU is because DJVU files generally ARE smaller than the same files in PDF.

I use free PDF printer drivers, they do good job. But PDF size can be 5-10 times larger.

I downloaded the trial version of the STDU converter (thanks for the pointer!), and I like the auto-cropping feature in principle for viewing on the DX, but it seems to be a bit too aggressive. In many cases it trimmed off part of the actual text. Is there any way to make it keep a bit of a margin? I tried playing with the 'threshold' value, but that just made it crop more, not less. There's also no documentation that I could find.

The cropping feature does seem aggressive, but I never lost any text. The main pain with the cropping for me is that any smudge,trash markings on the sides of the page keep the auto-crop from zooming in on actual text.

I have not seen any documentation, alas. I thought there was a way to do manual cropping on a page and use that for the whole document, but I forgot how(if it ever existed). I am going to keep fiddling with it, I do need a good djvu to pdf converter, I doubt the kindle DX will ever directly support djvu.

is it possible to have any kind of linux djvu viewer installed/added to kindle?
anyway it is linux.

Sorry for "up" this old topic.

DjVu has better algorithms to encode B/W images with text. But in last version of our converter we use JBIG2 algorithm for B/W images, and have good results, resulting PDF larder only on 10-20% then the djvu.

If you still interest this, can you send to us (support@stdutility.com) some file, with bad autocrop, and may be we will can improve this options.
