V0.6
====

New features:

- Added SWIG support, as suggested and basically implemented by
  Rainer Schaaf (Rainer.Schaaf@T-Online.de). SWIG support allows us
  to use PDFlib routines from Tcl, Perl, and Python.
  (makefile, pdflib.i, pdftcl_wrap.c pdfperl_wrap.c, pdfpython_wrap.c,
  pdflib.pm).
- New directory structure: BINDINGS directory contains subdirectory
  for several PDFlib language bindings. Currently these are
  C, CGI, Perl, Tcl, Python (yes, I know that CGI is not a language).
- Included scripting samples (BINDINGS/*/pdfclock.[pl|tcl|py],
  BINDINGS/*/hello.[pl|tcl|py]).
- Added new function PDF_setpolydash, suggested and implemented
  by Evgeny Stambulchik <fnevgeny@plasma-gate.weizmann.ac.il>
  (p_gstate.c, pdf.h).

Bug fixes and minor enhancements:

- Fix trivial (but fatal) free/fclose bug (p_font.c)
- Slightly change syntax of pdfgraph sample program: fill and
  stroke is denoted by 'F' instead of 'B' (pdfgraph.c)
- Shorten the version string (pdf.h)
- Add cast (p_basic.c)
- Conditionally typedef bool because of conflicts in VC++ (pdf.h and p_port.h)
- Add cast (p_font.c)
- Delete old BOOL typedef (pdf.h)
- Renamed function parseFile to pdf_parseFile in order to avoid name
  clashes with other software packages. This change was requested
  by Evgeny Stambulchik for the xmgr package. This package uses T1lib
  which also includes a copy of Adobe's AFM parser. (afmparse.c,
  afmparse.h, p_font.c).
- Fixed typo in the Goethe demo text (pdfdemo.c).
- Adjusted demo data to new setrgbcolor interface (test/graphdata).
- Add PDF_HAS_BOOL define. However, it doesn't really fix the multiple 
  boolean define/typedef/enum problem (p_port.h).
- Removed const from PDF_info struct members. This change is related
  to SWIG support, although the necessity of the change is not yet
  fully understood (pdf.h).


V0.5 (25 February 98)
=====================
Portability aids, bug fixes and other improvements from several contributors:

- JPEG images could be closed multiply (p_jpeg.c)
- Introduce Mac and Win32 porting defs (p_port.h)
- Use define for path separator which is needed for the Mac's ":"
  (p_port.h, p_font.h)
- Rename structure member private to private_data for C++ compatibility
  (pdf.h, p_font.c, p_gif.c, p_jpeg.c, p_tiff.c)
- NeXT portability: include libc.h (imagepdf.c, pdfclock.c, pdfgraph.c, 
  text2pdf.c)
- Don't use malloc.h (afmparse.c)
- Change variable handling in make build process (makefile)
- Fix bug in octal character representation (p_text.c)
- Introduce word and character spacing functions (p_text.c)
- Fix subtle bug in font embedding: fonts with additional data after
  the zeros portion were not properly embedded (p_font.c)

Environment bindings:
- Introduces BINDINGS directory which will collect several language and
  environment bindings for PDFlib.
- Sample CGI script for the PDFclock example (BINDINGS/CGI/clock.cgi)

Several bugfixes, due to Detlev Droege's comments after
testing with his PDFviewer:

- Avoid empty /Filter arrays for uncompressed binary images (p_image.c).
- Change erroneous number of color components in demo page (pdfdemo.c).
- Implement consistency check for color components vs. color space
  (p_image.c)
- Write binary magic number for all files (ASCII and binary) (p_basic.c).
- Change "Producer" to "Creator" in sample application (hello.c).
- AFM handler crashed in case the AFM parser gave up on certain AFMs (p_font.c).
- AFM parser didn't correctly handle newer version 4.0 AFMs (afmparse.c).
- Use AFM 4.0 key "StdVW" for a more accurate /StemV in font descriptor 
  (p_font.c).
- API CHANGE: Change RGB parameters from byte to float since
  gray values are float parameters too (p_color.c).


V0.4 (8 September 97)
=====================
First public release.

- Generating multiple PDFs with embedded images resulted in wrong
  XObject numbers for the second and following PDFs. Use image_number
  from the PDF structure instead of a static variable.
  (p_image.c, p_basic.c)
- Makefile for Watcom C 10.6 included in the distribution, support
  Windows build (makefile.wat).
