Programming Snapshot – Fyne
With the Fyne framework, Go offers an easy-to-use graphical interface for all popular platforms. As a sample application, Mike uses an algorithm to draw arrows onto images.
My new favorite language, Go, impresses with its image processing routines, manipulating the pixels in an image just as quickly as ordinary numbers or text [1]. I often paint arrows in digital images, either for illustration purposes or to point out something funny in a snapshot, and I wondered how hard it would be to automate this task.
