I'm currently using the Borland C compiler with the Borland C++ 3.0
under plain Dos . I found the BGI driver is too slow to access Video
Memory and I hardly found it supports 256 colours at VGA mode ... So , I
want to use the DJGPP instead of my original one . 

	Therefore I want to know the requirement of using it ? 

Thank you in advance

Mr X


 or in to the
screen. This could be done by this algorithm:

Z1=(X2-X1) * (Y1-Y0)
Z2=(Y2-Y1) * (X1-X0) 

Z3=Z1-Z2

X0,Y0 is the first corner in the poly and X2,Y2 is the third corner.
You must define each poly with the coordinates in the same order.
Going clockwise is a good rule.

Mayby I just messed things up for you. Email me for a better
description ok!
