Re: [Plplot-devel] pdf driver
Hi Andrew, Nice ! About five years ago I wrote a PDF driver using a PDF library whose source code was available, but wasn't Open Source - rather some unusual licence - so shelved it. I looked at libharu as an alternative when they first released it, but at the time it was dependent on C++, so I didn't pursue it at all. Having looked at their web page just now, it seems that version 2 is ANSI C - is that right ? Or does it still have dependencies with C++ ? No, there are no dependencies on C++ anymore. It's in ANSI C and it seems to compile on all compilers without problems. 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. A4 is probably best for everyone EXCEPT North Americans, so don't feel bad about that ! Yes, you are right :) Might I also suggest letting the user set their own explicit page dimensions using plplot's regular command line options as well as flags for pre-defined sizes ? Sure. This should be no probmen at all - I'll also have a look at the psc driver how it is done there. -Werner - Take Surveys. Earn Cash.

Re: [Plplot-devel] pdf driver
Hi Alan, Here is what I did. * Unpack, configure, build, and install libharu-2.0.8 [...] * However the pdf device part of the build did not work: [...] Werner, let me know if you need any more information to duplicate this pdf device build error on your Linux box with libharu-2.0.8. I think I know where the problem is and will fix it, the next time I boot into Kubuntu. Dual booting is a pain ;) libharu seems mature; the 1.0.0 version was released in 2003, and there has been a steady series of releases ever since. I understand there are few [...] libLASI). Werner, once you solve the Linux build issue, I suggest you donate your fix to the developer of this package to see how he cooperates. I actually think the problem is on our (cmake module) side, it is not a bug in libharu, we'll see, but if it's a bug I'll contact him (there seems to be also another bug, so I'll contact him anyway). For the Linux brochure project (lbproject.sf.net) I get satisfactory conversions from postscript to pdf results using ps2pdf. Thus, you may want to compare -dev pdf results with -dev psc or psttfc results that have been transformed by ps2pdf on your Linux box. Will do that. I know, that one could use ps2pdf, but than it's an additional step and not easily available on Windows. However, your device should ultimately give better results since generic postscript to pdf transforms (regardless of whether done with ps2pdf on Linux or some equivalent tool on windows) will likely miss out on some pdf features you can get with a native pdf device driver. Adding TrueType fonts (I checked that libharu claims to support those) will be essential for -dev pdf users, and the compression feature you mentioned would be nice as well. But the top priority is the Linux fix. I have an idea how to manage the 3rd party libraries problem, especially on Windows it needs now a big amount of time to get everything ready if you want to include all. I'll write an another email soon. -Werner - Take Surveys. Earn Cash.

Hi Alan, Werner, let me know if you need any more information to duplicate this pdf device build error on your Linux box with libharu-2.0.8. I think I fixed it, though I haven't been to Linux yet. I'll do that tomorrow. If you have time, you can give it a try again. -Werner - Take Surveys. Earn Cash.

I think I fixed it, though I haven't been to Linux yet. I'll do that tomorrow. If you have time, you can give it a try again. Thanks, Werner. That was a good catch. The Linux build error is now gone, and the only apparent build issue remaining is the following warning: /home/software/plplot_cvs/HEAD/plplot_cmake/drivers/pdf.c:162: warning: passing arg 1 of HPDF_New' from incompatible pointer type. However, that did not seem to affect the results with this device. I installed and did a superficial install-tree test using c/x01c -dev pdf -o test.pdf When the resulting test.pdf file was viewed with the gv application, there appeared to be an overgenerous bounding box, but otherwise the rendering looked okay including the black background that is supposed to be there. A similar test with the xpdf pdf viewer showed the same bounding-box issue and a white (!) background. This might be an issue with how -dev pdf creates the background colour of the plot because if I use -dev psc and transform the result to pdf using ps2pdf, xpdf renders that transformed result with the correct black background. So it appears xpdf can render the background colour correctly, but it is sensitive to exactly how that background colour is created. Anyhow, it seems your new pdf device is a good start, and I suggest you will want to include this device as an option in plplot-test.sh so we can easily generate pdf's for all install-tree examples as a test of -dev pdf.

[Plplot-devel] pdf driver
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.
