I know Ghostscript can convert PDFs to JPGs, and in the case of a multi-page PDF, can rip each page to an individual JPG. But is it possible to have it rip them to one JPG, so that the pages are pasted below each other, e.g. the top half of the JPG is page 1, the bottom half is page 2? Or do I have to use another program (and can ImageMagick do this?) to combine the JPG pages into one image?
View 2 Replies View RelatedI've spent hours trying to scan + shrink a multipage PDF documentlosing readability. This is the first time I've ever needed to do this! (I had to scan each page as ".jpg" in order to email and open on another computer, so I could not scan to PDF directly, which I think is why each page was so large; lower DPIs made the text too blurry.)I found this great tip on UbuntuGeek...but anyone can do this if GhostScript is installed:

Compiling ghostscript (9.01 or older) on a SUSE-11.3 does not include the x11 devices.gs -h does not show x11, x11alpa, x11mono, etc.Compiling on an old SLES-9.3 all x11 devices are included.On the old SLES-9.3 there is a library /usr/X11R6 with subdirs lib and include.Apparently including x11 devices depends on the libraries in /usr/X11R6.Question 1: how do I compile ghostscript on suse-11.3 with x11 devices included? The option --with-x does Question 2: where can I get the appropriate /usr/X11R6 for SUSE-11.3?

I'm trying to get GS to print to network Windows printer, but somehow fail to do so . I managed to print through CUPS to that printer but if I use GS with -sDEVICE=cups nothing happens, nothing is printed, CUPS logs remain unchanged... I also found command using smbclient (gs ... | smbclient //machine/printer -U user ... -c 'printmode graphics;print-') but that one fails with "session setup failed: NT_STATUS_REQUEST_NOT_ACCEPTED" Here is why I need it, so maybe you know better way: We need to print thousands of PDF files in one print job (to prevent anybody else to send something else in while we are printing this). I was trying to develop small C program using GS API to achieve this but somehow I fail on something as trivial as print something on shared network printer.
View 3 Replies View Relatedim using cups filter 'texttops', to generate postscript file, then I;m using ghostscript to create pdf file. The problem is, that file generated from texttops don't contain landscape orientation instructions. How can I force ghostscript to do that. Here is the command Im using:
gs -sDEVICE=pdfwrite -sOutputFile=<outfile> -dBATCH -dNOPAUSE -f <infile>
I've found on the internet these instructions, but they don't work for me:

I'm having trouble finding information on using gstreamer to convert videos from the command line. I've seen examples to convert audio and know it's possible to convert video (Thoggen does this with gstreamer) but what would the command be to execute this? I assume it will use gst-launch but there are so many following switches that it gets confusing. I'm interested in converting a DVD to OGG (as Thoggen does). I ask this because Thoggen:
1) Doesn't remember my preferences (quality, picture size etc.)
2) Gives me a huge preview window that I do not need (while it is encoding)
Used mpg123 command to convert mp3 to wav files. It is been converted fine but the question is why the file size is get differed?

Is there any specific reason in it?
I have to send a FAX (as some recipients are about 20 years behind the times). Sometimes the document looks excellent on the screen, but what comes out the other end looks terrible. So I'm trying to come up with a way to produce the best quality FAX from a vector PDF (which is searchable with images and text). Part of the goal is to preview the fax in advance, so there are no surprises. I start by converting the vector PDF to a raster (bitmap) postscript document:

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.
