pic2C++ is a simple tool to change images into byte arrays (or arrays back into an images) for use with (monochrome) displays such as OLEDs on your Arduino or Raspberry Pi.
It was originally made to work with the Adafruit OLED library.

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.

Adds some extra Arduino code around the output for easy copy-paste into
this example.
If multiple images are loaded, generates a byte array for each and appends a counter to the identifier.

If multiple images are loaded, generates a single byte array.

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 ouput. Used by a modified version of the Adafruit GFX library.

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.
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.
