Project Overview

Description

Lists possible coordinate types in the ChemDraw application.

Types of Coordinates

TypeDescription
CurCoords These are integer based coordinates, representing screen pixels

InternCoords
called "points"

These are floating point coordinates to track positions precisely (without dealing with pixels)
1 point = 20 CurCoods
CDXCoords These are InternCoords, converted to integers by multiplying them by 100 (there are only two significant digits)
The factor of 20 is an internal scale factor so that any screen resolution can be accommodated
