Users who view their GMT PostScript output using pageview in OpenWindows on Sun computers or user older laserwriters may have difficulties with the European font definition. If your installation of OpenWindows followed a space-saving suggestion of Sun, you may have excluded the European fonts, in which case pageview will fail to render your plot.
Ask your system administrator about this, or run this simple
test: (1) View a GMT PostScript file with pageview.
If it comes up OK, you will be fine. If it comes up blank,
open the ``Edit PostScript'' button and examine the lower
window for error messages. (The European font problem generates
lots of error messages in this window). (2) Verify that the
PostScript file is OK, by sending it to a laserwriter
and making sure it comes out. (3) If the PostScript file is OK but it chokes pageview, then edit the PostScript file, cutting out everything between the lines:
%%%%% START OF EUROPEAN FONT DEFINITION %%%%%
bunch of definitions
%%%%% END OF EUROPEAN FONT DEFINITION %%%%%
Now try pageview on the edited version. If it now comes up, you have a limited subset of OpenWindows installed. If you discover that these fonts cause you trouble, then you can edit your .gmtdefaults4 file to set CHAR_ENCODING = Standard, which will suppress the printing of this definition in the GMT PostScript header. You can make output which will be viewable in pageview without any editing. However, you would have to reset this to TRUE before attempting to use European fonts, and then the output will become un-pageview-able again. If you try to concatenate segments of GMT PostScript made with and without the European fonts enabled, then you may find that you have problems, either with the definition, or because you ask for something not defined.
