I'm uploading a preview version of v0.4.0.
This release have some major change into the architecture for allowing filtering of images.
Actually it does some filtering to the images before compression to improve quality (those are not configurable yet).
I would like to know if this does really help the display quality on e-book readers.
Do someone know the shades of gray of the sony reader? actually I'm using the iliad ones also on the sony.
P.S.
V0.4.0 is really buggy so i leave v0.3.1 for normal uses

I know it is an early release, but the "completion" status no longer generates a vertical scroll bar when it runs off the page, so it is a bit hard to see the progress (ignoring the status bar) after about 10-15 converted pages.

the status bar don't work too?

The status bar does work, but dissapears once complete. It would be nice to have some sort of visual that it was finished converting with no errors. Perhaps by leaving the status bar up.

Thanks for the update, I really have to get some time tomorrow to test out this new build. Just to clarify a few things we talked back and forth about earlier in the month; I loaded up the demos you posted for normal vs. lossless, but didn't notice too much of a difference. Hopefully I'll get a chance to break out the camera and grab you a screen grab to post tomorrow too.

I checked Sony's website and the official word is 4-level grey scale (their words) and that seems to be the consensus with others in the Reader groups when they wax technical; i.e., limitations of eInk and hopes of some type of color eInk in the near future. Have a good day/night!

The missing scrolling is a bug and will be fixed in next preview version

That was to test if the lossless format was compatible with the reader , actually due to the low number of colors there is no real advantage to use lossy instead of losses, so lossless meas more quality at about same size.
The test version does also some filtering to increase image quality and (hopefully) text readability.

I already know that I was asking for the "gray palette" to reduce the image to that palette. Actually I'm using the iliad palette so the sony reader have to reduce the color palette from 16 colors to 4. I want to produce a 4 colour palette so the sony should do almost nothing

Cya

I've just upload v0.4.0 preview 2

[Vaporware]

Any chance of supporting .zip and .cbr (.rar) compressed archives for easy conversion of whole issues? I just did my first conversion and this script is great

[Kirys]

cbz and zip support is planned, while cbr is not, the reason is that there is a native support for zip file in java, while rar is a closed format.
This could change if i find a good lib for uncompress rar files.

Decompressor for RAR is free and the source is easily available for download. You can also use unrar.dll.

[Kirys]

The software is in java and I want it to be fully cross-platform so using external libs is not an option.
The unrar code is c, porting this code to something compatible with the compression interface of java would take a lot of time.
So actually cbr/rar files support is not planned.
But never say never, as i said if i'll find a small and compatible java lib maybe i'll add the support to the planned features.
But till now there is a lot of features needed beore cbz support (like page splitting )
We'll see

[Vaporware]

Yeah, CBR and zip aren't really important. It would be nice to split double page spreads instead of shrinking them. Some Scanlations don't include the individual left/right pages.

[Kirys]

I've added v0.4.0 final.
let me know if you find any issue with it

[Vaporware]

Actually, I have an issue that I believe is not related to your program at all. It's sony reader specific behavior. When viewing pictures as a JPG in the picture viewer function, the reader does a MUCH more thorough job of the black/white flash to remove any trace of ghosting. It almost looks like a double page turn. When I read with PDF, I almost always have ghosting of the previous page because it only does a single page turn. Do you think re-packaging the PDF as an BBeB could have a toggle for the double page turn?

Well the latest version of Java has been release and unfortunately PNG conversion still does not work

Error when attempting to convert is:

Generating output for: Iliad portrait
Exception:java.lang.IllegalArgumentException: LUT has improper length!
Total Processing time:0s
