Yet another PDF to LRF converter - Page 36

megacoupe · 09-04-2009, 12:59 AM

You're just not looking hard enough.

A search for "pdflrfwin" on demonoid.com and thepiratebay.org will show you torrent results. In the comments sections of both places, you'll find a link to direct download if you don't know how to use torrents.

Heck, even a google search for "pdflrfwin" gives you both torrent and direct download link results on the first page! You won't find things if you don't look for them.

demono..what?

Thanks for your tip. Had to be happy with the Windows version, the Linux one seems to have fallen down into the inkpot.

Well, the Windows version works on Linux with Wine and looks really pretty stable.

So I had a quick try with a 2.1 M pdf about Roman history in A4 format. A difficult one indeed with lots of photos and maps or genealogical trees. It was converted in some minutes into a 26.4 M lrf file. Calibre opened it successfully after a one minute loading time.

You read the lrf output in landscape mode. The texts parts are nearly legible. By this I mean that the font size is OK but the line is trimmed (you need to scroll left right about 1/8 to read it). It means the default settings have of course to be tweaked to suit your own book (if possible?).

For the maps and the photos, you get them and at least you have a decent idea what it's all about but no more.

For your information, here is a view of the main window with the book loaded, just to have an idea of what are the default setting values and a the screenshot of a page as seen with calibre with visualization mode (I turned it counterclockwise for you)

For a quick and not too dirty reading...can be tried.

We were talking about the linux version. Believe me, I searched every torrent site I could find, and rapidshare search engines, etc., ... I just can't find it.

pdflrfwin is not the problem. I have that, and I use it through a virtual machine and it works fine... I'd just rather have the linux version.

I did notice that the windows version runs under Wine, but at least for me, is horribly slow -- so slow that I do better in a virtual machine. It's a lot of rigamarole, but often still worth it.

I have used this program to convert files previously, but I have a file that for some reason at around 25% the program just closes. It doesn't give me an error, but it just closes. Is there any way of figuring out what is happening so I can resolve this? Thanks.

Update: I've figured it out. For some reason in the pdf there were a few pages that were different size (they were blank pages). When I removed those out of there it was able to complete processing of the file.

frabjous · 10-30-2009, 09:21 AM

No, but you can use it to optimize your pdf files, rainbless. (You'd have to use calibre or similar to convert the LRF files, though, since Kindles don't read LRF files.)

You might try sopdf instead, which is PDF > PDF to avoid a step like that.

Quite agree. Just tried it and it is great. Quite and solves the problem of trimming the margins on my PRS-600 -the preview is really helpful.

Nate the great

Hi, I've taken some of the ideas of existing tools along with a few refinements of my own to code this one up. I've attached a few sample conversions to get an idea of what the tool can do.

The refinements are --runpages (which causes adjacent pdf pages to be spliced into the same image if possible) and --smartcut (which avoids the annoying splits at the edge of the image) Another feature is that landscape mode (which is the default) rotates the image but doesn't actually use the Reader's landscape mode.

f_l.lrf outputs the page that can be viewed by rotating the reader (-rs)
f_p.lrf outputs the page in portrait mode (-prs)
f_po.lrf outputs the page without runpages and smartcut (-p)
g_2col.lrf sample of two column mode (-vrs)
comicl.pdf comicp.pdf strips in landscape and portrait mode (uses --nosplitpage -rs)

The pdf files tested are linked here

version 0.2 now reads in cbz and djvu files. It also reads pdf files using poppler - so you do not need to install ghostscript.

version 0.3 has a windows gui. --portrait has been removed and replaced by --rotation. Default is portrait now. Also metadata from pdf files are automatically read

version 0.4 adds drag/drop and batch processing (drag mutiple files over) + other small refinements (not specifying smartcut/runpages/splitpage scales a page to fit in an image)

version 0.5 has support for pre-trimming off the input pages. These are specifed in terms of % of the page from the left/right/top/bottom that you want to trim away. They can also be specified independently for even/odd pages. Also unicode metadata is now supported.

version 0.6 adds support for unicode filenames (previously only unicode metadata was supported), cbr/rar files, better error reporting and assorted bug fixes.

version 0.7 adds preview of pre trimming, catrom filter for resizing images, png files are now generated for embedding in lrf files. Converted over to using threads - so batching is a lot more improved.

version 0.8 adds support for Table of Contents in pdf files. It is possible to preview output images to test out various settings. An experimental linux build (built on Ubuntu) has been added. Improved threading support so processing should be faster. Changed default colors to 4 to reduce frequency of file size questions. Added more filtering options and better dithering so images should look a lot better.
Fixed threading bug that causes it to hang occasionally under linux. Fixed TOC. Erosion now works sensibly with small images (like those of comic strips). Can also go down to 2 colors.

version 0.9 Added padding (in pixels) when using runpages. Fixed crash bug when generating toc. Added back ghostscript support. Added option to disable generation of TOC.

version 0.99 Fixed Librie compatibility (maybe). Adjustable image size on output. Output zip files (if extension is cbz or zip). Added RGB output. Added post stretch of image to fit page. Added options to fit image by height/width/2*height etc. Sort files in rar and zip.

Fixed bug in dos and linux commandline versions that ignored toc. Fixed metadata bug.

I've broken out the dos commandline, windows gui and linux commandline versions into separate files to better track usage.

Sorry for this stupid question, but I can't find a link to download the converter. On the first pages everything appears as a picture or text but not a valid URL link. What am I doing wrong?

Ok, I missed the point:

If you read through the last few pages of the thread, you'll find ways of acquiring it, however. (At least if you want the windows version; if you want the linux version, like me, alas you may be out of luck.)

nerys · 02-27-2010, 05:17 PM

I am confused. What is the issue here? the software is free using GPL stuff.

SO what is the problem with simply COMPLYING with the GPL requirements? just release the source? is the creator gone or something so no one HAS the source?

IE why can it not be PUT into COMPLIANCE ?

frabjous · 02-27-2010, 10:47 PM

The author has not released the source. He does occasionally stop by here, but hasn't explained the noncompliance.

cacapee · 02-27-2010, 10:54 PM

Strictly speaking, I'm in compliance as I'm not distributing the tool anymore.

Cheers
