huykhoong/gif2cpp ? reverse-engineered prompt

Build me a simple web tool that turns GIF animations into C or C++ byte arrays for monochrome displays like OLED and LCD screens on Arduino, ESP32, or Raspberry Pi.

I want to upload a GIF, see a live preview of the frames, and tweak things like threshold, scale, invert colors, flip, and rotate until it looks right. Then let me choose the output style for Arduino, plain C or C++, or ESP style output, and generate code I can copy straight into my project. It should also let me download a header file. Support the common draw modes for monochrome bitmaps, and make sure the generated output works well for frame based animation on small displays.

Keep the interface simple and practical, since this is meant for quickly converting GIFs into something I can paste into microcontroller code. If you need current docs or examples for the display libraries, look them up online.
