This is a utility that expands on the One-Dollar page at the University of Washington. It requires the use of one-dolla, which is 100% compatible with one-dollar, with enhancements for this utilty. It will let you examine points loaded into one-dolla in more detail, and copy points from a JSON file to visualize them.
The Canvas element is not like other HTML elements and getting the app working was most easily done by coding against the UI in the view models. We may be able to get around this with custom bindings for the canvas element.
The Canvas drawing relies on knowing the position of the canvas element on the window. This is determined once on the dollarRecognizer page when the page loads, but should be recalculated after a window resize.
One of the primary use cases for this tool is to create a custom gesture library you can use to initialize one-dolla. The output button currently dumps the data on the sceeen, but it would be better is that button put the data on the clipboard.
