Announce: AnimatedGifs fork now usable as a library

For my own use, I further modified my fork to allow being used as a library.
See this super short example on how to display an animated GIF in your own code:

github.com

marcmerlin/AnimatedGIFs/blob/master/SimpleGifAnimViewer2/SimpleGifAnimViewer2.ino

#ifndef ARDUINOONPC
#define BASICARDUINOFS
#endif
// Use NeoMatrix API, even if it may use the SmartMatrix backend depending on the CPU
#define NEOMATRIX
#include "GifAnim_Impl.h"


// If the matrix is a different size than the GIFs, allow panning through the GIF
// while displaying it, or bouncing it around if it's smaller than the display
int OFFSETX = 0;
int OFFSETY = 0;
int FACTX = 10;
int FACTY = 10;

// Setup method runs once, when the sketch starts
void setup() {
    #if defined(ARDUINOONPC)
	const char *pathname = FS_PREFIX "/gifs128x192/abstract_colorful.gif";
    #elif defined(ESP8266)

This file has been truncated. show original

This library also supports:

seamless switching between SmartMatrix and NeoMatrix backends
gamma correction on the fly on NeoMatrix backend (via serial)
changing files by index number or previous/next (via serial)
ESP8266 support for NeoMatrix
SPIFFS support on ESP8266/ESP32 (no sdcard needed)

Hope this helps someone.
