******* 2.3 --> 2.3.4
|
|
- BCC2GRX is now part of the GRX graphics library.
|
|
******* 2.0 --> 2.3
|
|
- will use the floodfill() from GRX 2.25 or newer
|
|
- Linux: can be compiled as shared library (make SHARED=1 in src/)
|
|
- made all functions direct linkable (mostly for GPC support)
|
|
- Pascal (GPC) support by Sven Hilscher included
|
|
- updated for grx21 (patterns & custom lines)
|
|
- No more warnings using LIBBCC.H in C++ programs
|
|
******* 1.3 --> 2.0
|
|
- new copyright terms, see readme
|
|
- compiles with both grx v2.0 and v1.03
|
|
- text.c splitted
|
|
- added setactivepage(), setvisualpage() and helper func's
|
|
set_BGI_mode_pages(int p), get_BGI_mode_pages(),
|
|
getactivepage() and getvisualpage() (functional only with
|
|
grx v2.0 or newer)
|
|
- __gr_Y_page_offs disabled if compiled for grx 1.0x
|
|
- restrict RGB values in setrgbpalette() to 0..63
|
|
- added extended graphics modes from BC++ 4.5
|
|
- few experimental custom line hacks for grx 2.0 (lnestyle.c)
|
|
- more work on Makefiles, make in src or test subdir works
|
|
- Due to limited stack space with DJGPP v2, complete rewrite
|
|
of floodfill() to avoid deep recursions.
|
|
- DJGPP: libbcc2.a will work on v1 and v2 systems with grx10, no need
|
|
to keep libbccx.a any longer.
|
|
- Link test: create dummy executable using all library objects. Nice to
|
|
check grx20fix.h settings.
|
|
- Optimized makefiles and configuration
|
|
- getdrivername() will report GRX driver name with GRX2
|
|
- LINUX: saved some getpixel() calls for floodfill() under X11. Remains slow :-(
|
|
- LINUX: No need to keep a seperate X11 directory any longer, binaries
|
|
are just linked with -lgrx20X -X11 instead of -lgrx20 -lvga
|
|
- LINUX: Enhanced Linux support (svgalib && X11)
|
|
- rewrote bgi font loading
|
|
- libbcc.h won't include GRX stuff any more
|
|
- rewrote floodfill(): Will use it's own dumb monochrome
|
|
context to keep track of drawn points. Uses less memory but
|
|
seems to be a little slower in few cases.
|
|
- moved _ega_color, setrgbdefaults() and setrgbgray256() from libbcc?.a
|
|
to src/addons.a
|
|
- added four new functions getmodemaxcolor(), getmodemaxx(), getmodemaxy()
|
|
and setrgbcolor().
|
|
- added version check __BCC2GRX__ (equals to 0x21a for v2.1 alpha,
|
|
0x20b -> v2.0 beta, 0x230 -> v2.3 offical release, ...)
|
|
|
|
******* 1.2 --> 1.3 (1.3 didn't made it to public)
|
|
|
|
- Vector fonts may be plotted using the actual line style.
|
|
calling textlinestyle(1) enables and textlinestyle(0) disables
|
|
this feature.
|
|
- corrected getmodename() TrueColor definition, name of actual
|
|
graphics mode valid now, will display 32K/64K/16M instead of
|
|
huge numbers
|
|
- CGA/MCGA/ATT400 will be emulated by 16 color modes
|
|
- EGA64HI sets 16 color mode on non EGA cards
|
|
- named source files in a more functional way
|
|
- circle() will use GrCircle() in "round" cases
|
|
- graphdefaults(), setgraphmode() and initgraph() set up the
|
|
correct aspect ratio
|
|
- added __gr_ prefix to several library functions called
|
|
by other bcc2grx functions. Protects against interference
|
|
with other libraries (problem reported by Axel Rohde)
|
|
- updated for libgrx 1.03
|
|
- should work with .vdr drivers now
|
|
- uses GrGetLastArcCoords() instead of global variables
|
|
- BLACK changed into constant
|
|
- Pascal support improved. KeyPressed and ReadKey will
|
|
flush stdout first, updated Readme
|
|
- bccbgi now uses random() instead of RANDOM_TP() for correct
|
|
support of >32768 colors modes. (Bad news: random() is much slower)
|
|
- set_BGI_mode_whc translates 64K and 16M color values into
|
|
GRX internals 0xC010 and 0xC018 (grx1.0x only)
|
|
- added _ega_color for EGA color emulation in HiColor/TrueColor modes
|
|
- Corrected range check in setfillstyle() (bug found by Axel Rohde)
|
|
- Corrected bugs/problems reported by Antonio Carlos Moreirao de Queiroz:
|
|
- initgraph won't crash if pathtodriver == NULL
|
|
- When loading a font failed, DEFAULT_FONT size 1 will be used
|
|
- font switching should be faster now
|
|
- if a font can't be found, grFontNotFound error will be set.
|
|
- Correct name expansion in installuserfont()
|
|
|
|
******* 1.1 --> 1.2
|
|
|
|
- installuserfont() accepts GRX font names (name.fnt).
|
|
- getmodename() supports modes >32768 colors
|
|
- initgraph() has NATIVE_GRX driver entry. NATIVE_GRX supports
|
|
the default, biggest (noninterlaced), BGI_mode graphics and all valid
|
|
modes from .grn drivers
|
|
- set_BGI_mode()/set_BGI_mode_whc() routines to emulate BGI driver resolutions
|
|
- floodfill() doesn't uses second context in simple cases (much faster),
|
|
leaves viewport if no clipping required
|
|
- getmoderange(), getmaxmode() and getpalettesize() will call
|
|
__gr_set_up_modes() first -->> returned values are initialized
|
|
- closegraph() resets __gr_INIT flag
|
|
- cleardevice(), clearviewport(), imagesize(), graphresult(), getmaxcolor(), getgraphmode(), getpixel() and
|
|
putpixel() are checking __gr_INIT flag now
|
|
- setrgbpalette() check's initgraph(), moved from bccgrx.h -> bccgrx20.c
|
|
- drawpoly() always closed the polygon -- fixed.
|
|
- registerfarbgifont() now same as registerbgifont()
|
|
- setgraphbufsize() returns a defined value
|
|
- setwritemode() protects against setting color bits
|
|
- detectgraph() returns the correct graphdriver info
|
|
- graphdefaults() doesn't call setlinestyle() & setviewport() any more
|
|
- bccgrx.c/__gr_set_up_modes() executed once only (fixes memory waste)
|
|
|
|
******* 1.0 --> 1.1
|
|
|
|
- initgraph() will set the requested graphmode if graphdriver != DETECT.
|
|
- using GrHLineNC and GrPixelNC in bccgrx09.c / _floodfill()
|
|
- BCC2GRX should run correct with old style drivers (.grd)
|
|
(bccgrx.c/__gr_set_up_modes changed)
|
|
- Corrected detectgraph()/initgraph() problem calling Gr... funcs
|
|
before GrSetMode()
|
|
- Used normal filled / solid line commands where ever possible
|
|
- Text direction and justify setting compatible with Borland definition
