Hi PostScript Hackers,
PdB version 2.1 (ANSI-C to PostScript compiler) is now available via
anonymous ftp from:
turing.com (192.133.90.28) in pub/pdb2.1-demo.tar.Z
ftp.uu.net (192.48.96.9) in graphics/NeWS/pdb2.1-demo.tar.Z
There is no more need to write PostScript! Start using PdB right now! PdB
is an optimizing compiler to compile ANSI-C (like) code into Adobe
compatible PostScript. It includes executables, examples and many useful
header files. Note that it is not dependend on NeWS.
The release of version 2.1 includes:
- Binaries for Sun SPARC station and IBM RS6000.
- Include files for Abobe PostScript level I.
- Include files for NeWS upto version 3.1.
- Include files for TNT upto version 3.1.
- Support for CPS OpenWindows upto version 3.1.
- Support NeWS classing in a C++ manner.
- Plenty of examples of all the above functions.
- NeWS/OpenWindows test suite.
- PostScript reference manual.
- UNIX manual pages.
Below are some examples of PdB code together with the PostScript
produced by the compiler.
Have fun,
Arthur van Hoff
