The intention is to be able to measure distances on an image relative to an initially marked known distance.
gh-pages demo
How to use the tool:
- Upload an image to the canvas, ideally a line drawing
- Left click to mark the beginning of a know distance on the image
- Left click again to mark the end of the known distance
- An input box will appear into which you should put the known distance
- Again mark any two points
- And again an input box will appear. This time input a name for this dimension.
- The name of this dimension and distance will appear both on the canvas and along the left side of the page.
- You can also set constraint so that you can only draw either horizontal or vertical lines.
- Using the 'Save as' dropdown menu, to save the canvas as a .png image
- Or save as a .scad file of variables for openSCAD.
- Or save as a .txt file of the variables for general use.
