Delphi Graph Source code Graphics Library

Geometry.pas was assembled different sources (like GraphicGems)

and relevant books or based on self written code, respectivly.



Note: Some aspects need to be considered when using Delphi and pure

assembler code. Delphi ensures that the direction flag is always

cleared while entering a function and expects it cleared on return.

This is in particular important in routines with (CPU) string commands (MOVSD etc.)

The registers EDI, ESI and EBX (as well as the stack management

registers EBP and ESP) must not be changed! EAX, ECX and EDX are

freely available and mostly used for parameter.-Delphi Graph Source code Graphics Library
