% Public domain
%
% HISTORY:
% E version released during the GUST annual meeting Bacho\TeX'95.
% P wersja udost/epniona podczas Bacho\TeX'95.
% VERSION 0.51, 5 V 1995:
% E macro \CMYKinit added (it places necessary def's in a PS prolog).
% P dodane zosta/lo makro inicjalizacyjne `\CMYKinit',
% kt/ore umieszcza w prologu PS u/zywane definicje.
% VERSION 0.52, 27 VI 1995:
% E the `currentpoint' fault in case of empty current path; now `currentpoint'
% is called by the `stopped' command, which makes an error action
% availlable.
% P `currentpoint' generowa/l b/l/ad gdy bie/z/aca /scie/zki by/la pusta;
% obecnie `currentpoint' jest wykonywane przez `stopped',
% co daje mo/zliwo/s/c zareagowania na b/l/ad.
% VERSION 0.53, 23 VII 1996:
% E 1. the constant `epsilon=0.005' entered to do approximed
% color comparations.
% 2. \PSscreen became a \special.
% P 1. wprowadzono sta/l/a `epsilon=0.005', kt/ora jest dok/ladno/sci/a
% por/ownania kolor/ow.
% 2. \PSscreen by/l dot/ad makrem TeX-owym o tre/sci PS-owej
% sensowne jest, aby sta/l si/e \specialem
% VERSION 0.54, 8 XI 1996 r.
% E `show' redefinition allows the text outlining.
% P redefinicja `show' umo/zliwia ju/z dok/ladanie obw/odki do tekst/ow.
% VERSION 0.60, 11 IV 1997:
% E processing of CMYK bitmaps enabled
% P umo/zliwienie przetwarzania bitmap CMYK
% VERSION 0.61, 11.VIII.1997
% E `adddownstroke' added (stroke under fill)
% P dodano `adddownstroke' (rysowan/a pod fillem)
% VERSION 0.62, 24.IX.1997
% E `setscreen' gets all parameters
% P `setscreen' zyskuje wszystkie parametry podawane explicite
% nie korzysta si/e z warto/sci `currentscreen'
% VERSION 0.64, 9.VII.1999
% E bitmap color separation added, delblack (also for imagemask),
% additional 5-th all-white bitmap separation (\BITinit and /to_sep_bitmap true def /hax_sep 4 def)
% additional 6-th all-black bitmap separation (\BITinit and /to_sep_bitmap true def /hax_sep 5 def)
% P do/l/aczono rozbarwianie bitmap, delblack (tak/ze dla imagemask),
% 5. bia/ly wyci/ag z bitmap (\BITinit oraz /to_sep_bitmap true def /hax_sep 4 def)
% 6. czarny wyci/ag z bitmap (\BITinit oraz /to_sep_bitmap true def /hax_sep 5 def)
% VERSION 0.65, 6.VIII.1999
% E 5-th and 6-th bitmap separation were improved (`pop' added
% in the case of not-dictionary images)
% P poprawka w 5. i 6. wyci/agu bitmap (dodano `pop' w bitmapach
% nies/lownikowych)
% VERSION 0.66, 13.IX.1999
% E indexed color bitmaps support (for `colormap')
% P obs/luga bitmap paletowych (do `colormap')
% VERSION 0.67, 21.01.2000
% E support for multisource `colorimage' -- only CMYK separations
% P obs/luga wersji wielo/xr/od/lowej polecenia `colorimage'
% -- na razie tylko CMYK i tylko separacja
% VERSION 0.68, 16.03.2000
% E \projectCMYK calls setcmykcolor explicite
% P \projectCMYK wywo/luje explicite setcmykcolor
% VERSION 0.70, 27.03.2000
% E image, colorimage and imagemask operators are transferred to
% their dictionary form and we support them almost completly;
% limitations: we support only bitmaps with
% ImageType = 1, in one of Device Color Spaces,
% when BitsPerComponent = 1 (other values of BitsPerComponent
% we allow for imagemask, of corse, and for DeviceGray model --
% without color substitution, unfortunately)
% P oparatory image, colorimage oraz imagemask przeniesione do wersji
% s/lownikowej i prawie kompletnie obs/lu/zone;
% ograniczenia: obs/lugujemy tylko bitmapy, dla kt/orych
% ImageType = 1, model barw nale/zy do klasy Device Color Spaces,
% BitsPerComponent = 8 (inne warto/sci BitsPerComponent dopuszczamy
% oczywi/scie dla imagemask oraz w przypadku modelu DeviceGray --
% wtedy jednak nie potrafimy podmienia/c kolor/ow)
% VERSION 0.71, 10.04.2000
% E 3 bugs fixed:
% 1) we already support MultipleDataSources in ImageDict
% 2) it was a superfluous pop in merge_multi3
% 3) 1 level of redefinition setcmykcolor (hax_setcmykcolor) added
% P usuni/eto 3 pluskwy w obs/ludze image:
% 1) ju/z obs/luguje si/e MultipleDataSources w ImageDict
% 2) by/l zb/edny pop w merge_multi3
% 3) dodano 1 poziom redefinicji setcmykcolor (hax_setcmykcolor)
% VERSION 0.73, 28.04.2000
% E 1) \sepbitmapfalse turns bitmap separation off,
% \sepbitmaptrue turns bitmap separation on
% 2) missing ImageDict parameter added before ori_image
% P 1) \sepbitmapfalse wy/l/acza rozbarwianie bitmap,
% \sepbitmaptrue przywraca rozbarwianie bitmap
% 2) dodano brakuj/acy parametr ImageDict przed ori_image
% VERSION 0.74, 11.05.2000
% E Bug in \delblacktrue handling has been fixed;
% the colors created from black with changecolor can be separated now.
% P Poprawiona pluskwa w obs/ludze \delblacktrue;
% mo/zliwe staje si/e rozbarwianie kolor/ow powsta/lych z podmiany
% koloru czarnego.
% VERSION 0.75, 15.06.2000
% E \convertbitmaptrue turns on conversion of RGB bitmaps to CMYK,
% to allow them to be separated
% \convertbitmapfalse truns conversion off, by default, RGB bitmaps
% are neither converted nor separated
% P \convertbitmaptrue w/l/acza konwersj/e bitmap RGB do modelu CMYK,
% co umo/zliwia ich rozbarwianie
% \convertbitmapfalse wy/l/acza konwersj/e bitmap RGB do modelu CMYK,
% co uniemo/zliwia ich rozbarwianie; domy/slnie bitmapy RGB nie s/a
% ani konwertowane, ani rozbarwiane
