Name & Parameters: [color:red][big] RectCoordinatesSub ( pieceA ; pieceB ; materialA ; materialB ; positionX ; positionY ) [/big]

Description: Returns the coordinates of rectangles (with dimensions pieceA x pieceB,) that can be cut from an area of materials (with dimensions materialA x materialB), starting from positionX, positionY.

This is designed to be used by the xmChart plugin to generate a graphic representation of how to cut the most pieces from the material.

This is a sub function of RectCoordinates(), located here (along with a demo):)

AddRect( 0;12;12;12;white)¶

AddFrame(0;12;12;12;1;black)¶

Recursive: yes

Formula:

//RectCoordinatesSub ( pieceA ; pieceB ; materialA; materialB; positionX; positionY )



/*
