Draws a polygone with NumberOfPoints corner points, using the current color and line-style. PolyPoints is an array of type PointType.
Draws a polygone with NumberOfPoints corner points and fills it using the current color and line-style. PolyPoints is an array of type PointType.
Fills the area containing the point (X,Y), bounded by the color BorderColor.
Returns a string with the name of modus Modus
InitGraph initializes the graph package. GraphDriver has two valid values: GraphDriver=0 which performs an auto detect and initializes the highest possible mode with the most colors. 1024x768x64K is the highest possible resolution supported by the driver, if you need a higher resolution, you must edit MODES.PPI. If you need another mode, then set GraphDriver to a value different from zero and graphmode to the mode you wish (VESA modes where 640x480x256 is 101h etc.). PathToDriver is only needed, if you use the BGI fonts from Borland.
Example:
var
gd,gm : integer;
PathToDriver : string;
begin
gd:=detect; { highest possible resolution }
gm:=0; { not needed, auto detection }
PathToDriver:='C:\PP\BGI'; { path to BGI fonts,
drivers aren't needed }
InitGraph(gd,gm,PathToDriver);
if GraphResult<>grok then
halt; ..... { whatever you need }
CloseGraph; { restores the old graphics mode }
end.

To get back to the graph mode you were last in, you can use SetGraphMode(GetGraphMode)
If UserBitln is specified then Pattern contains the bit pattern. In all another cases, Pattern is ignored. The parameter Width indicates how thick the line should be. You can specify one of the following pre-defined constants:
Vertical controls the vertical placement of the text, relative to the (graphical) cursor position. Its value can be one of the following pre-defined constants :
DefaultFont = 0; TriplexFont = 1; SmallFont = 2; SansSerifFont = 3; GothicFont = 4; ScriptFont = 5; SimpleFont = 6; TSCRFont = 7; LCOMFont = 8; EuroFont = 9; BoldFont = 10; |
