Browser fingerprinting protection can cause the RGB values of image data returned by context.getImageData() to be randomly off by a little bit (usually -1 or 1). So instead of solid black being rgba(0, 0, 0, 255) as expected, it might be rgba(0, 1, 0, 255) or similar.

Here's a guide on how to get set up with the FedEx API and start making requests.

I was working on a 2D game in Unity and needed some way to automatically create a collider for a complex 2D level mesh. Editing a Polygon Collider 2D in the editor was out of the question, since there were thousands of vertices. I ended up writing a script that analyzes the MeshFilter of the mesh, and programmatically creates a Polygon Collider 2D for it. It also supports meshes that have mutliple non-connected components.

Note: This code uses Amazon AWS Signature Version 2, which is not available on any S3 Regions created after January 30, 2014. It is recommended to use Version 4. Please view the AWS Version 4 post here.
