fl_anim_gif's Introduction

FL_Anim_GIF

Original project: https://github.com/wcout/fltk-gif-animation

Changes

Added functionality to load GIFs from memory buffers.

Removed redundant x,y constructor in favor of default arguments and reversed the order of name and position parameters for better overload resolution.

Added Fl_Anim_GIF constructor overload to support loading GIFs from memory buffer.

  Fl_Anim_GIF(const char *name_, int x_, int y_, int w_ = 0, int h_ = 0,
              bool start_ = true, bool optimize_mem_ = false, int debug_ = 0);
  Fl_Anim_GIF(const char *name_, const unsigned char *buf_, int len_,
              int x_, int y_, int w_ = 0, int h_ = 0,
              bool start_ = true, bool optimize_mem_ = false, int debug_ = 0);

Added _init overloads:

  void _init(bool start_); // tunneling point for both original _init and new overload
  void _init(const char *name_, char *buf_, int len, bool start_, bool optimize_mem_, int debug_); // new overload

Added load overload:

bool load(const char *name_, char *buf_, int len_, bool from_file_ = false);

Added set_name helper function for load

void set_name(const char *name_);

The changes above are also, obviously, reflected in the implementation file (.cxx)

Installation

Either place the files directly in your source directory or compile to a stand alone static library and link against it (fltk_gif.lib). Remember to include Fl_Anim_GIF.H in both cases.

Usage

unsigned char my_gif[] = {/* some gif bytes here */};
Fl_Anim_GIF animgif(0, 0, 500, 500, NULL, my_gif, sizeof(my_gif));
