A new guide today in the Adafruit Learning System: Saving CircuitPython Bitmaps and Screenshots

Working with graphics in CircuitPython is a joy. CircuitPython has support for a plethora of screen types and a rich set of functions to perform graphics operations.

When working on a device that has a screen, it can be useful to programmatically take a snapshot what’s on the screen and save it into a file for examination or use later. This could be for various reasons including capturing graphics for use at another time and/or system, debugging the code that is putting pixels on the screen, or use in documentation. It can also be useful to be able to save the contents of a bitmap, for example in PyPaint.

This guide introduces a CircuitPython library which is compatible with CircuitPython 5.0 and later. The library allows the programmer to take the pixels in a bitmap or on a screen and save them into standard 24 bits per pixel BMP files. Files may be on the CircuitPython USB flash filesystem (if it’s set to writable mode) or onto an SD card.
