- added support for reusable images
- updated man pages
Version 0.4.4
- fixed impropper use of font in ps_stringwidth() (thanks to Roger Wimbert)
Version 0.4.3
- renamed getline() to afm_getline() in ps_afm.c because never versions
of libc have an equal symbol
Version 0.4.2
- fixed bug in ps_setcolor()
- made src/hash_table.c compile on hp ux
- fixed typo in input encoding table
- fixed man pages
- fixed several memory leaks
Version 0.4.1
- fixed DSC in postscript file (makes ghostview for ms windows happy)
- configuring using cmake now checks for libpng, libjpeg, libtiff, libz
Version 0.4.0
- Also disolve a ligature if it isn't present in the font encoding vector
- handle duplicate glyphs in an afm file nicely, without leaking memory
- many small changes to make it compile for win32 in a mingw and
visual C environment (includes support for cmake)
- added function PS_glyph_list() which returns a list of all glyphs
in a font. Free that list with PS_free_glyph_list()
- added function PS_glyph_width() which returns the width of a glyph
- changed mode of fopen to "rb" to make it work in win32
- added functions PS_[begin|end]_font(), PS_[begin|end]_glyph()
for creating Type3 fonts
- added functions PS_add_kerning(), PS_add_ligature() for setting
kerning pairs and ligatures of a font.
- added PS_glyph_show() for outputting a glyph by its name.
- fixed sourceforge bug 1556247, 'ordmaskuline' must be 'ordmasculine'
Version 0.3.0
- PS_string_geometry() uses the passed font and not the current font
(Closes #1711438 at sourceforge)
- added section about color separation in man page of pslib
- check for byteswap.h because mingw doesn't have it
- default error handler now prints to stderr instead of stdout (reported
by Johannes Frank, fixes debian bug #429544)
- parbreak has no effect if linebreak is set (previous segm reported
by Johannes Frank, fixes debian bug #429543)
- BMP support can be disabled
- PS_place_image() doesn't check for mimetypes of unsupported image
formats
- support for separating colors. Just set the value 'separationcolor'
before creating a new page to 1-4 (1=cyan, 2=magenta, ...)
- added missing include file for freebsd
- Support for other input encodings (currently only latin1 and latin2, more
can be easily added)
- Replaced TeXBase1 by Cork fontencoding because it supports more glyphs
- ps_check_for_lig() gets extra first parameter *psdoc in order to be able
to access the inputencoding stored in psdoc
Version 0.2.7
- fixed setting of locale
- PS_set_border_style() works as expected
- added blind feature to PS_show_boxed()
- added support for gif, tiff and bmp images
- PS_show_boxed() sets the value 'boxheight' to the actual height of
the box. This is useful if you specify a height of 0.0 for the
box and need to find out how high is has become. It is also useful
if a box isn't completely filled.
- passing a height of 0.0 to PS_show_boxed() will create a box long enough
to contain all text.
- strip alpha channel from rgb pngs, because they cause a segm fault. Once
I understand where the actual problem lies, it will be reenabled.
- make euro symbol work (replaces the currency symbol)
- PS_arc() and PS_arcn() behave like the arc and arcn postscript commands
- fixed rpm spec file
- PS_continue_text() finally works as expected
- PS_get_buffer() checks for psdoc->sb before accessing it
- PS_begin_page() does not overwrite the BoundingBox and Orientation
anymore, if it has been explicitly set by PS_set_info()

- PS_add_bookmarks() works even with characters in the bookmark text
which are not allowed in PostScript strings (like '(', ')')
- PS_open_image() can read eps images from memory
- fixed encoding vectors at position 363-365
- jpeg cmyk images can be read without segm fault
- char to disolve ligatures can be set as parameter 'ligaturedisolvechar'
- Entering PS_PATH_SCOPE always starts a new PostScript path
(newpath). This fixes the clipping bug.
- both, grayscale and rgb jpeg images can be read
Version 0.2.5
- fixed ascii85 encoding
- fixed memory leak in PS_find_font() and PS_include_file()
- various fixes which caused segm fault under solaris

- can now read jpeg images
- image data is being ascii85 encoded to reduce file size
- Fixed bug in PS_fill_stroke(), invalid PostScript because of missing space
Version 0.2.2
- access inputencoding vector through ps_inputenc_naem() which uses
the encoding vector of the document.

files opened for reading, e.g. afm, pfb, enc and all include files.

used and the font is not embedded.
- PS_get_paramter() can return current scope
- initial separation of fill and stroke color
- check parameter c1-c4 of PS_setcolor() for being in range 0-1.0
- PS_setcolor() accepts 'fillstroke' as second parameter to set both
stroke and fill color.
- use PostScript commands setgraycolor, setrgbcolor, setcmykcolor and
setpattern because some PostScript programs for color separation
rely on it.
- added functions PS_setoverprint() and PS_makespotcolor()
- Resources will be put into the prolog if they are created before
the the first page. This allows to extract certain pages from the
document without missing the resources in the new document.
- added new scope PS_SCOPE_OBJECT, PS_SCOPE_PROLOG

how to use the library.
- added function PS_set_text_pos()
- much better handling of builtin font encoding
- allow to get more values of a font with PS_get_value()
- New functons PS_symbol(), PS_symbol_width(), PS_symbol_name()

values like fontsize, capheight, etc. are requested. modifier is the
font id.
- PS_show2() did not use textx and texty
- renamed PS_stringwidth3() to PS_string_geometry()
Version 0.1.13
- PS_hyphenate() better handles non alpha chars
- updated man pages
Version 0.1.12
- much better hyphenation of words with capital letters and words starting
with none alpha charaters like '('
- huge speed improvement if PS_show_boxed() is called several times and
hyphenation is turned on, because the hyphenation table is now loaded once.
- added fulljustify mode for PS_show_boxed()
Version 0.1.11
- include files are back in ${prefix}/include/libps
- added nested bookmarks
Version 0.1.10
- this fixes all build problems of the last version
Version 0.1.9
- fixed some very nasty bugs which caused a reproducable segm fault

the function makes a copy of it.
- fixed potential segm fault in PS_show2() when text has more than 299
chars, no space and kerning is turned off.
- Underlining is not using the descender as set in the font metrics but
the one calculated for the text to show. This places the under line
much closer to the text if the text has no descender.
Version 0.1.6
- value 'textrise' can be used to lift text above the base line
- many code cleanups
- new function PS_stringwidth3() to retrieve more dimensions of a string
- set extra space between paragraphs (parskip)
- Behaviour of cr at line end/on a single line can be set to either
be treated as a space or a line break/paragraph break.
- indenting first n lines of a paragraph, starting with the m'th
paragraph is now possible

page containing about 3000 characters needs now about 10 sec as
opposed to 70 sec for creation.)
Version 0.1.4
- improved different ways of text rendering
- support for output of invisible text
- added pkgconfig and *.la files to rpm devel package
- check if resource exists before creating a new one
Version 0.1.3
- do not return from PS_show_boxed() if hyphenation cannot be
done, but simply turn if off and issue a warning.
- fixed building of rpm package
- many man page cleanups
- all string parameters passed to a api function are constant
- fixed some nasty compile errors
- added more BuildDepends
Version 0.1.2
- fixed many memory leaks

internal resources. The API reffers with interger ids. This simplies
its handling from the users point of view.
- imagewidth, imageheight can be retrieved by PS_get_value()
- PS_open_mem() returns int
- implemented text rendering
- removed some debuging messages

- massive source reorganization
- added support for pkg-config
19/12/2002
- Appearance of ligatures in text causes segm fault, fixed.
- '(' and ')' are written as octal values into PostScript file,
because they have a special meaning in PostScript.

file
- Ligatures can be turned on and off (parameter "ligatures")
