4ebd215a8c * changed definition of getscanlineproc to "getscanline(x1,x2,y: 
integer; var data);" so it can be used by getimage too
  * changed getimage so it uses getscanline
  * changed floodfill, getscanline16 and definitions in Linux
    include files so they use this new format
  + getscanlineVESA256 for 256 color VESA modes (banked)

    not DIV!!

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

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

cb55fd4de2 * FloodFill: did not take into account current viewport settings 
* GetScanLine: only get line inside viewport, data outside of it

    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

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...

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)

  * getVESAInfo (protected mode) would still continue on with
      setting up the VESA structure, even if VESA was not
      detected!
