Ubuntu :: Using "convert" To Make PDFs
Jun 16, 2010
I have been using the terminal command "convert" to make PDFs and I noticed that some of the pictures are out of order. The script I wrote is thus:
Quote:
#!/bin/bash
cd /home/zach/Documents/PDFing
convert *.jpg -resize 50% *.png
[code]...
During the stage where all the images are .png, they are still ordered properly in the folder. However upon converting to a PDF, some of them are in the wrong places. They are all uniformly named with numbers in the proper order, so that is not an issue.Is there a way that I can force "convert" to order strictly by name? The man pages were interesting, but did not help me in this situation.
Post Scriptum: I'm running 10.04 LTS Desktop Edition.

When I run
convert *.jpg output.pdf
the output looks like this:
Why is the first page bigger then the others in the PDF? The original JPEGs were all the same size!

How do I make imagemagick convert things one at a time? I know how to make imaggemagick convert all pages of a pdf into individual jpeg files by storing it all in the RAM at once but if there isn't enough RAM, this will use swap like crazy and be suuuuuuuper slow.
Here is the command for the "crazy swap-using" way:
convert --units PixelsPerInch -density 150x150 filename.pdf filename.jpg

I find that some pdf files will not print properly in 32-bit 10.04 using evince. The document is sent to the printer and then the printer simply flashes and never prints the document (I have waited an hour). The same documents *will* print quickly when I print with acrobat reader, although when using reader the the following error message appears in the terminal:
(acroread-en:3915): Gtk-CRITICAL **: gtk_progress_set_percentage: assertion `percentage >= 0 && percentage <= 1.0' failed
The printer is a lexmark X364-dn. The problem seems particularly acute with documents that have been scanned.

Somehow in the last couple of days, my adobe acrobat reader quit working online. I can read pdf files on my computer, but if try to access one through my google browser, I get a blank page. What can I do to fix? I tried downloading the most recent update of adobe but when I went to run the program I get an error message indicating there is no program to open the update file.

how I can get elinks to open pdfs using xpdf? I know that there are other browsers/pdf programs but I'm using this across the internet and this seems to be the lowest bandwidth option!

Ubuntu 9.04 and a Konica 2430 DL on USB. I can get a Ubuntu test page from the printer management screen (printout says GPL. Postscript version 3010 revision 864) and I can print from Firefox. I cannot print PDFs from either Acrobat or Evince. The print jobs show up as completed in the print jobs list.

I read few threads from 2006, and at that time it seemed there was no good way to save a PDF which had data input in the form fields. Has this changed? Printing is not really an option, since I won't fill these forms in one sitting. When I save with Ubuntu's default PDF viewer, the form field data does not seem to be saved along with the PDF.

I'd like to be able to change the program that downloaded PDFs open with in Firefox. I'm using Gnome. Currently, when I double click on a PDF in the downloaded file list, it opens up in Adobe Reader, even though evince is currently the default in nautilus. How I can change it so that downloaded files are opened with evince?

I am trying to download all the Heroes graphic novels off the nbc site. Originally I was downloading them via the provided links but with ~170 pdfs to download it was going to take a while I used wget to start downloading them a bit faster, I tried the command
$wget -N -r -l inf -p -np -k -A '.pdf' url
in an attempt to download all the pdfs at once, I got an error message
--2011-04-01 13:17:14-- url
Resolving url... 92.122.49.98, 92.122.49.235
Connecting to url|92.122.49.98|:80... connected.
HTTP request sent, awaiting response... 403 Forbidden
2011-04-01 13:17:15 ERROR 403: Forbidden.
Is this something I've done wring or something nbc have done to stop the use of wget?

Using Ubuntu 10.10. I cannot set Firefox to open PDFs with evince. Actually I have no idea where it grabs mime info from. I know I could manually choose /usr/bin/evince or something, but isn't there a way to make Firefox simply see what my desktop settings are, or at least offer me the choices?

I recently popped in the CD that came with one of my textbooks from school and figured I would be able to rip it pretty easily, but guess what? Too my surprise I find that each chapter of the textbook has it's own PDF file and that each one is encrypted. Is there anyway I can decrypt the PDFs and merge them all into one?

Like [Okular-devel]bug report okular started to crash when opening some pdf files after upgrade to kde 4.3.4 I found out that the probelm was not actually in kde but another update - at some point poppler (libpoppler4, libpoppler-qt4-3 and others) was updated to 0.10.1-1.7.1 but okular did not work fine with it any more. I solved the problem by downgrading poppler back to 0.10.1-1.4 (repo-oss) and all pdfs worked fine again. The bug report above states that newer okular would need actually newer poppler (0.12.x) but it is not provided at least for opensuse 11.1 yet.
OpenSuse 11.1 64 bit
kernel 2.6.27.39-0.2-default

Is it possible to do the following without using the Adobe reader?Adobe Reader (acroread) has a nice search feature that allows to search for strings inside all .pdf files in certain directories (e.g. show me all lines containing the word "recursion" in all PDF files in or below directory "/papers", which gives you a neat clickable list and the sentence for each hit).I much prefer Okular for viewing PDFs, but I am at a loss on how to duplicate the above feature without acroread under linux. The KDE FindFile apparently does not search inside PDFs, or at least not in an intelligible way. I do have Nepomuk running, hogging resources, but I don't understand how to query it - if this is possible at all. So what can I do besides using acroread?

Ok this is a problem that has dogged me for years but I was hoping it was fixed in 11.4. Using the acroreader plugin pdfs sometimes work but most often they result in a white or black blank screen and once one pdf has failed then they all fail until I restart firefox. It is a huge pain - under kubuntu I have used mozplugger to display pdfs with okular in the browser but this doesn't seem to be in the repos.
I don't think it is just me, all the people I know using suse seem to have this problem but it never gets fixed. how to get pdfs reliably displayed in firefox?

I installed evince on my Arch Linux system as a PDF reader, and everything was fine for a while. And then I installed GIMP. Since then, PDF files have been opening in GIMP. I've tried reinstalling evince, I've tried editing ~/.local/share/applications/defaults.list , I've tried editing /usr/share/applications/mimeinfo.cache, but PDF files still open in GIMP by default.

I found a particular pdf in wich okular's review function is not working. Whenever I press F the review menu doesn't show, and by trying to access it via tools -> menu it looks like the function is disabled. Why does this happen in a particular pdf (all other pdfs I've read in okular didn't have this problem).

When I upgraded from debian lenny to squeeze, my iceweasel browser was upgraded at the same time (3.5.15), and I'm having difficulty getting it to function as it used to.When I visit sites that link to PDF files, they download automatically, when what I want is for the PDF to be displayed by the browser. I have Applications for PDF set to Always Ask.I have PDF Download as an extension, and under its Preferences I have Open PDF as default action, using the xpdf utility on the host, opened in same tab, caught by name. I do not have a PDF plugin. Is the PDF Download extension forcing a download rather than display of the PDF in the browser?

I use Okular to create bookmarks in my pdf files, but those bookmarks won't appear in WinXP (Adobe Reader). Same problem when I use xpdf or ePDFViewer in slackware.
Are there any tools/apps in linux which can create PDF bookmarks & retain them in other PDF viewers? I don't want to buy & use Adobe Acrobat just for this function.

I have Ubuntu 9.04 and just installed Sound Converter. I am trying to convert a bunch of .ogg files to mp3 to play on my iPod and it's not working so well. In the Sound Converter options I have is set to convert to high quality mp3. I choose the folder that the files are in and after a moment (slow laptop) Sound Converter populates, I hit 'convert' and it shows that the conversion completes in two seconds. All that it did was create the new folder structure of artist/album but there is nothing in there. Not sure what I am missing. I used Sound Converter before and it worked fine.
