Coordinates in Chalk
|
|
|
|
As with any paint app, finding out what you mean when you say (x,y) is difficult.
|
|
There are the screen coordinates, the coordinates of the canvas inside the view,
|
|
the zoomed coordinates -- and the image coordinates, paint device coordinates and the
|
|
coordinates of the data inside the paint device.
|
|
|
|
Iterators are created in terms of the image coordinates.
