Re: [Dr. Geo] proportionOf:to: method ?

[Hilaire Fernandes]

Hi David,

This is Smalltalk land where the user is empored. Therefore the idea is:

- You add your own category in DrGeoSketch class. Let's say 'David extensions'

- In this category you add the method as you mentioned, for example #proportionOf:to:and:to:

The method will be used proportionOf: A to: B and: C to: D

Take great care in the naming, this is the most important

- You fill the method with the code I show you.

- Then you can fileout the 'David extensions' method category

- To load it back in a new image, you use the FileList tool

I can assist you in the process

The code you suggested is fine and is generic, but it would be shorter 
and more convenient if DrGeo provided a method to compute the constant 
of proportionality for either 2 line segments or for 4 endpoints ...
