adafruit/Adafruit_CircuitPython_ImageLoad

Super-slim image decoder that loads code as needed to minimize memory use

Introduction

This library decodes an image file into new bitmap and palette objects of the provided type. It's designed to load code needed during decoding as needed. This is meant to minimize the memory overhead of the decoding code.

Only certain types of bitmaps work with this library, and they often have to be exported in specific ways. To find out what types are supported and how to make them, see this learn guide page.

Usage Example

import board
import displayio
import adafruit_imageload

image, palette = adafruit_imageload.load(
    "images/4bit.bmp", bitmap=displayio.Bitmap, palette=displayio.Palette
)
tile_grid = displayio.TileGrid(image, pixel_shader=palette)

group = displayio.Group()
group.append(tile_grid)
board.DISPLAY.root_group = group
while True:
    pass
