Hello Hiro,

that is easy: you use a different driver than the PS or Xterm drivers. 
If you look
at the examples and run them, you will see that they first ask for the 
driver you want
to use. Presumably you set the driver directly in your program(s). If 
you do not, that is,
do not call plsdev(), then you should get a list of the available 
drivers too.

Jpeg requires the GD library - I do not know whether that is standardly 
available
on OSX, if not, you will have to install it yourself. Aquaterm ought to 
be supported
without extra stuff, if I understand your platform correctly.

Arjen

If you put "call plparseopts(1)" as the first plplot fortran call in your
code (e.g., before call plinit()), you can use a command-line option, e.g.,

./x01f -dev jpeg

This method is used for all our many fortran examples, see
examples/f77 and examples/f95.

Alternatively, I believe you can hard-code a device in your fortran code
using, e.g., call plsdev('jpeg'), but I never use that method since the
command-line option is so much easier to use.

Thank you for the quick reply.

My code always includes "call plparseopts(1)" before plinit(1). But,  
when I build the code as "g77 x01f.f `plplot-config --cflags --libs -- 
with-f77` -o x01f" and then the code shows "Requested device jpeg not  
available" when the code run as "./x01f -dev jpeg".

Does that thing mean that my system doesn't have output driver and  
installation of PLplot was failed ? How to do that ?

I have another question. If I use intel fortran 9.1 to build the cord  
with PLplot, the code shows "plparseopts: negative number of  
arguments" when the code run. But I can get right plot result. What  
is problem under this situation ?

Regards,
Hiro

That means that the libraries that the jpeg driver uses are not
available on your
system. Check the installation instructions for this and rebuild PLplot.

No, the PLplot installation did not fail. PLplot optionally uses a
number of third-party
libraries. If these are not found during the build process, the
resulting PLplot library/installation
simply can not use the drivers and other facilities that depend on them.

For instance:
If you do not have a C++ compiler, then the C++ bindings will not be
built. This
is however independent of the Fortran bindings (they require a F77 or a
F95 compiler).

Similarly, some device drivers require extra libraries - GD for GIF.
JPEG, PNG ... If the GD
library is not found, these device drivers are turned off.

The problem is that the wrong number of arguments is passed on from the
runtime libraries.
We have looked into the problem a few years ago but were unable to solve
it - it is something
deep inside the runtime libraries. Simply ignore it.

I'm not sure what your requirements are that you need JPEG, but as  
you probably know, PDF is native across OS X (even the screen display  
is based on PDF). You can save directly from AquaTerm in either PDF  
or Postscript.

If you want to convert to other file formats such as JPEG (and you  
don't have to do this many times), it is easy to copy directly from  
the front AquaTerm window (Command-C), switch to Preview.app, and hit  
New from Clipboard or just Command-N. From there you can save as any  
of BMP, GIF, JPEG, JPEG 2000, PDF, Photoshop, PICT, PNG, SGI, TGA, or  
TIFF.

Of course, if you need to convert to other formats, there is always  
the venerable Graphic Converter which knows about every graphic  
format ever devised.

Sorry if this is already known to you, but just in case....
