Optimize PDFs with Open Source
Submitted by mfn under Development , Open Source , Student's life , technology on 04/09/2010
Not everyone has an Adobe Acrobat Professional license and still less one has necessarily an operating system running on the Acrobat. That's why I've been looking for a way to optimize PDFs with Open Source software, so to reduce the file size by downsampling and compression of images.
And I'm found it. With the combination xpdf and ghostscript can be accomplished that.
I assembled a small script for Windows where you have to adjust only the paths:
set xpdf="X:\Path\to\xpdf"
set ghostscript="X:\Path\to\ghostscript\bin"
set suffix="_opt.pdf"
%xpdf%\pdftops.exe -paper match -level3 hsq.pdf tmp.ps
%ghostscript%\gswin32c.exe -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dColorConversionStrategy=/LeaveColorUnchanged -dBATCH -dNOPAUSE -sOutputFile=hsq.pdf%suffix% tmp.ps
del tmp.ps
The whole course is also under Linux / Mac if installed xpdf and ghostscript:
suffix="_opt.pdf"
pdftops -paper match -level3 hsq.pdf tmp.ps
gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dColorConversionStrategy=/LeaveColorUnchanged -dBATCH -dNOPAUSE -sOutputFile=hsq.pdf$suffix tmp.ps
rm tmp.ps
The more recent are the respective versions the better the result looks like. At least my experience.
Qtoctave Win32 0.9.1 bugfix
Submitted by mfn under General , Development , Student's life , technology on 05/04/2010
I found a bug in my windows version. So I patched the source, to fix it.
The problem was, that changes it's own qtoctave cwd when a file is loaded, and then share the directory is not in place anymore.
A fresh build of qtoctave-win32-0.9.1-2 qtoctave-win32-0.9.1-3
The new version 0.10.1-win32-qtoctave should fix these problems.
[Update]
Thx Dan for the report. I forgot a "\ \" + line in 118th octave_connection.cpp I uploaded version 0.9.1-3.
