85f0d28bf1 * fix for disposing font data because it can contain #0 chars 1999-09-28 15:07:46 +00:00
Jonas Maebe
03980540bd * reordered some local variables (first 4 byte vars, then 2 byte vars 
etc)
  * font data is now disposed in exitproc, exitproc is now called
    GraphExitProc (was CleanModes) and resides in graph.pp instead of in
    modes.inc

Jonas Maebe
aa5751acbc * changed name of modeinfo variable to vesamodeinfo and fixed 
associated errors (fillchar(modeinfo,sizeof(tmodeinfo),#0) instead
    of sizeof(TVesamodeinfo) etc)
  * changed several sizeof(type) to sizeof(varname) to avoid similar
    errors in the future

bd4d132c5b + detectgraph 
* small change to internalellipsedefault so less pixels are
    calculated twice
  * some small corrections to graph.tex
 1999-09-25 11:48:43 +00:00
Jonas Maebe
5f0cf70477 * optimized patternline a bit (always use hline when possible) 
* isgraphmode stuff cleanup
  * vesainfo.modelist now gets disposed in cleanmode instead of in
    closegraph (required moving of some declarations from vesa.inc to
    new vesah.inc)
  * queryadapter gets no longer called from initgraph (is called from
    initialization of graph unit)
  * bugfix for notput in 32k and 64k vesa modes
  * a div replaced by / in fillpoly

7e28f32cdc * changed ratios so font sizes on screen are the same as with TP 
* SetUserCharSize must also use / instead of DIV
 1999-09-22 14:54:11 +00:00
Jonas Maebe
cd377606a4 * changed org_to_cap, org_to_dec and org_to_base to shortints (from 
Michael Knapp's gxtext unit, part of the GraphiX package)
  * in settextstyle, the calculation of the ratios must be done with /,
    not DIV!!
 1999-09-22 13:30:52 +00:00

47b14faf20 * renamed text.inc -> gtext.inc to avoid conflict with system unit 
* fixed textwidth
  * isgraphmode now gets properly updated, so mode restoring works
    again

4e43bad546 + hlinevesa256 and vlinevesa256 
+ support for not/xor/or/andput in vesamodes with 32k/64k colors
  * lots of changes to avoid warnings under FPC
 1999-09-18 22:21:09 +00:00

34f074549c * graph.pp: removed pieslice and sector from ToDo list 
* closegraph: exits now immidiately if isgraphmode = false (caused
    RTE 204 with VESA enabled if you set exitproc to call closegraph
    and also called closegraph explicitely before exit, like bgidemo)
 1999-09-18 16:03:36 +00:00
Jonas Maebe
e188d82aec * another fix for a case where internalellipsedefault went haywire 
* sector() and pieslice() fully implemented!
* small change to prevent buffer overflow with floodfill
 1999-09-17 13:58:31 +00:00
Jonas Maebe
6ea818a303 * small change to internalellipsedef to be TP compatible 
* fixed directputpixel for vga 320*200*256

ecd28082fd * fixed PutPixVESA256 1999-09-15 11:40:30 +00:00
Jonas Maebe
66e28ab9c1 * fixed Arc: internallellipse went into an endless loop if StAngle = 
EndAngle
  * FillEllipse is now much faster: no more floodfill,
    InternalEllipseDefault now draws the patternlines immediatety!
 1999-09-13 12:49:08 +00:00
Jonas Maebe
062f4e5991 * several changes to internalellipse to make it faster 
and to make sure it updates the ArcCall correctly
    (not yet done for width = 3)
  * Arc mostly works now, only sometimes an endless loop, don't know
    why

947db5dbe3 * fixed outtext(''), c was a byte, this leads to an underflow and 
garbage was written
 1999-09-12 08:02:22 +00:00
Jonas Maebe
cb55fd4de2 * FloodFill: did not take into account current viewport settings 
* GetScanLine: only get line inside viewport, data outside of it
    is not used anyway
  * InternalEllipseDefault: fix for when xradius or yradius = 0 and
    increase xradius and yradius always by one (TP does this too)
  * fixed conlict in vesa.inc from last update
  * some conditionals to avoid range check and overflow errors in
    places where it doesn't matter
 1999-09-11 19:43:00 +00:00

bee7f62011 * removed and/or/xorput support from vesaputpix256 (not in TP either) 
* added notput support to directputpix256
 1999-08-01 14:51:07 +00:00
Jonas Maebe
51cc22f9c6 * fixed hline16 and vline16 for notput (also TP supports copy, and, or, xor and 
notput for lines!!)
  * fixed directputpixel16 to support all the different put types
 1999-08-01 14:50:51 +00:00
florian
49f7b705a6 * bar: y2 can be less y1, fixed 
* settextstyle: charsize can be 0, must be changed into 1
 1999-07-26 09:38:41 +00:00
Jonas Maebe
c023f717f1 + xor-, and and- orput support for VESA256 modes 
* compile with -dlogging if you wnt some info to be logged to grlog.txt

7821e9580a * small VGA detection problem solved 1999-07-14 14:32:12 +00:00
Jonas Maebe
3f127e3afc * bugfix in getmodeinfo (SizeOf(TModeInfo) -> SizeOf(TVESAModeInfo)) 
* as the result of the above bugfix, the graph unit doesn't crash
    anymore under FPC if compiler with -dsupportVESA, but it doesn't
    work yet either...
 1999-07-14 13:17:29 +00:00

d6f11f2061 * fixed procvar syntax error and ceil and floor functions 1999-07-12 14:52:52 +00:00
Jonas Maebe
8c70a5f38a * forgot log tag in previous commit 1999-07-12 13:28:33 +00:00
Jonas Maebe
d045295cd4 + added Log and Id tags 
* added first FPC support, only VGA works to some extend for now
  * use -dasmgraph to use assembler routines, otherwise Pascal
    equivalents are used
  * use -dsupportVESA to support VESA (crashes under FPC for now)
  * only dispose vesainfo at closegrph if a vesa card was detected
  * changed int32 to longint (int32 is not declared under FPC)
  * changed the declaration of almost every procedure in graph.inc to
    "far;" becquse otherwise you can't assign them to procvars under TP
    real mode (but unexplainable "data segnment too large" errors prevent
    it from working under real mode anyway)

InitGraph.

a890a867af + ImageSize() to Sector() documentation reviewed and updated. 1999-05-30 23:04:50 +00:00
carl
1bca153f22 * getVESAInfo (real mode) would always return TRUE, this would crash 
windowed VESA modes.
  * getVESAInfo (protected mode) would still continue on with
      setting up the VESA structure, even if VESA was not
      detected!
