image2cpp - Image to C Array Converter
image2cpp (LCD Assistant) is a free online tool for converting images into C arrays and byte arrays (or converting your array back into an image) for use with monochrome OLED and LCD screens, such as those found in Arduino or Raspberry Pi projects. Supports Adafruit GFX, U8g2 and MicroPython / CircuitPython output.

0 - 255; if the brightness of a pixel is above the given level the pixel becomes white, otherwise they become black. When using alpha, opaque and transparent are used instead.
Centering the image only works when using a canvas larger than the original image.

4. Output
Generates output in
bytearray format for Micropython and CircuitPython.This oled_example adds some extra Arduino code around the output to easily copy and paste it. If multiple images are uploaded, it creates a byte array for each one and adds a counter to the identifier.
Adds some extra Arduino code around the output for easy copy-paste. If multiple images are loaded, generates a single byte array.
Creates a
First ASCII character value is used only if a glyph identifier of length equal to 1 is not provided for each image. The value itself will be incremented by 1 for each glyph.
GFXbitmapFont formatted output. Used by a modified version of the Adafruit GFX library. GitHub project and example bitmap-fontFirst ASCII character value is used only if a glyph identifier of length equal to 1 is not provided for each image. The value itself will be incremented by 1 for each glyph.
If your image looks all messed up on your display, like the image below, try using a different mode.
Useful when working with the u8g2 library.
