LCDAssistant - image2cpp is a simple tool for converting photos into byte arrays (or converting your array back into a photo) for use with OLED (monochrome) screens, such as those found in Arduino or Raspberry Pi projects. This tool is especially useful for programming images on monochrome displays like OLEDs.

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.

creates a byte array for each one and adds a counter to the
identifier.

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.
