PDF Generation / PDFs greater than 4Gb 'need re...
Last post by kiwi_steve - June 07, 2024, 06:37:23 AM
Hi all, I have just spent a frustrating week back and forth with my printers for a book I have written in Scribus 1.5.8 over the last 4 years (it's worth noting I tried upgrading to Scribus 1.6 a while back, but it crashes every time I try opening the 1.5.8 file... so I have stuck with the older version).

The entire book is over 400 pages and has nearly 900 images, some very big.  With 'Compress Text and Vector Graphics' turned off during PDF creation, it comes out at 8.7Gb in size. 

This file will (unhappily) open in Acrobat Reader - I get a small window popup, titled 'Rebuild', and with the message 'This file is damaged but is being repaired'. After 20 seconds or so, the file opens, and looks fine.  The printers can't work with it, though.  This was terrifying for me for a while there, as I thought all my work was going to have to be redone in some expensive software that I don't know how to use, and don't want to have to buy or rent...

I eventually sent it in 4 smaller sections, which their printing system was able to reassemble, and so it looks like they can actually print it (I'll know more next week)... but it took some figuring out on their and my part.

Since then, I have made some trial exports to try and work out what is happening (each build takes quite a while to run) - if I set 'Compress Text and Vector Graphics' on, with Image Quality compression to None, and Maximum Image Resolution to 220DPI, the file size comes in at 3.7Gb, and the PDF will open just fine.  If I set the max DPI to 240DPI, the file size in 4.3Gb, and it throws the Rebuild warning.

My takeaway from this (at the moment, I am still experimenting) is that 4Gb, or thereabouts, is a limit.  I'm old enough to remember FAT32 (and possibly plain old FAT before that, but I'm not prepared to confirm that  ;D ) and the 4Gb file size limit associated with it... is this possibly something related?

Anyway, I would love to know if there is something about large PDFs created in Scribus that is causing this problem... I've tried searching for that Rebuild error message relating to Acrobat, but it gets drowned out by the more common failed to open, corrupted PDF error and the one link I did find, really didn't tell me anything useful.  I was also unable to find anything related to large PDFs in Scribus, other than a lot of people complaining about the PDF file size that Scribus creates (I don't really care about the size, I just want the printer to be able to take the PDF and turn it into a nice shiny book).

Has anyone struck this, or better - does anyone know why this is happening - or does anyone have a sensible workaround other than to limit the DPI during export (it's essentially a large-format picture book, so I don't want to reduce the quality or DPI of the images if I can avoid it).

Cheers, Steve

after mrb's post i had a short look into what are hyphenation dictionaries...

  • mrb's link brings as to the list of all dictionaries for libreoffice
  • i had a look on the italian and french "folders"
  • in both cases the hyphenation dictionary was converted from the existing latex one (https://en.wikipedia.org/wiki/LaTeX)
  • there seem to be no maltese dictionaries for libreoffice or latex
  • there is a maltese page for libreoffice but it does not seem to contain any link / resource specific to your language: https://mt.libreoffice.org/

so what you can do now?

i guess that the best is to get in touch with the libreoffice community or maintainer of a language that is close to maltese and see with them what you need to do for creating the language files for your language.

this having been said, i don't see any language pack for the european smaller / minority languages so it might be something that is hard to create / maintain...

You can just move or copy the files. Not sure why you would want to do that though?

Scribus uses the same format that libreoffice etc uses. We include a couple by default, but otherwise rely on a few options, sourced from the system via packages, via a LibreOffice etc install, or people can use the Scribus Resource Manager window to download them. Most of them are sourced via https://cgit.freedesktop.org/libreoffice/dictionaries/plain/. There's nothing there with the "mt" language either. It is not obvious that libreoffice has something elsewhere either. There may be a Maltese community that does this sort of work though such an an educational institution, ministry etc.
I suppose its not that hard to create the file but I don't know the formatting myself.

I'm using Scribus to format a book in Maltese. There is no hyphenation dictionary for this language. Are there guides to creating a hyphenation dictionary? What is the format used? I would appreciate any pointers.

thanks!

Text and Typography / Re: Small Caps Scaling
Last post by AdmFubar - June 04, 2024, 09:19:48 PM
Ok just did a some checking into this. Once the small caps size is selected in the user prefs, it cannot be changed for the document you are working one.

Was this the intent for this option? or an oversight? I'm thinking this option needs to be changeable, not  permanent for a document.

Text and Typography / Small Caps Scaling
Last post by AdmFubar - June 04, 2024, 06:14:36 PM
This doesn't seem to work in 1.5.8. Was trying to update a document and wanted to adjust the scaling between the first letter and the remaining letters. This setting is in the typography panel of preferences.

Can anyone else confirm? Also suggest making the small caps scaling available from the style panel as well.

Ok played with options. It is something inherent to my document that it isn't updating the small caps.

Made a new doc, added text and  and did a directly applied the small caps, and the sizing works.  Must be something with the styles I've applied to the text. Will investigate more and report back.

Quote from: finnishcoffee on June 03, 2024, 06:18:44 AMStill a lot of editing to do compared to just two cells but definately better then doing every single page...
Scrubis does seem to have a knack for crashing with masterpages that contains such things as tex frames tho.

How many different Master Pages do you have?
