Hi,
while working on a plot for my thesis I thought it would be cool to have
pdf output. I was googling around and found a free pdf library (zlib
license) in ANSI C, working on all major platforms:
http://libharu.sourceforge.net/index.html
So I took the svg driver, rewrote it for the pdf library, wrote some
cmake modules and ready I was (after some hours :).
To use this driver we need first to install it (configure/make/make
install for Linux, and make -f script/Makefile.??? for Windows) and set
the environment variables for cmake accordingly so that cmake can find it:
set HPDFDIR=%USER_ROOTDIR%\libharu-2.0.8
set PATH=%HPDFDIR%;%PATH% (for windows dll)
set CMAKE_INCLUDE_PATH=%HPDFDIR%\include;%CMAKE_INCLUDE_PATH%
set CMAKE_LIBRARY_PATH=%HPDFDIR%;%CMAKE_LIBRARY_PATH%
There seems to be no debian/rpm package of this library, so Linux users
need to compile this library as well.
Than run cmake with -DPLD_pdf=ON (since it is disabled by default) and
off we go.
Five remarks:
1) in pdf.cmake is a compile flag added which won't work for Unix
-DHPDF_DLL - this I need to change.
2) The paper size is hardcoded to A4 in the moment - good for Europeans,
bad for anybody else, I need to add some flags for other formats.
3) the font used is only the hershey fonts in the moment - on the basis
of the svg driver I should be able to add nice fonts.
4) I didn't test the driver on Linux yet, but I don't expect much problems.
5) Output is not compressed in the moment, since I need zlib for Windows
as well (not too much problem), so expect big files - but the driver is
actually very fast.
I hope this driver is useful - if my choice of the pdf library is not
welcome, there is not much problems using another one - if there is
another library which suits our needs better.
Regards,
Werner
