+
+GIF encoder
+===========
+
+This is a small C library that can be used to create GIF animations.
+
+Features
+--------
+
+ * user-defined palette of any depth from 1 up to 8
+ * each frame has its own (user-specified) delay time
+ * flexible looping options: no loop, N repetitions, infinite loop
+ * GIF size optimization: only stores frame differences
+ * memory efficient: saves frames to file as soon as possible
+ * small and portable: less than 300 lines of C99
+ * public domain
+
+
+Limitations
+-----------
+
+ * no frame-local palettes (incompatible with size optimization)
+ * no interlacing (bad for compression, useless for animations)
+
+
+Documentation
+-------------
+
+There are only three functions declared in "gifenc.h": ge_new_gif(),
+ge_add_frame() and ge_close_gif().
+
+The ge_new_gif() function receives GIF global options and returns a ge_GIF
+handler:
+
+ ge_GIF *ge_new_gif(
+ const char *fname, /* GIF file name */
+ uint16_t width, uint16_t height, /* frame size */
+ uint8_t *palette, int depth, /* color table */
+ int loop /* looping information */
+ );
+
+The `palette` parameter must point to an array of color data. Each entry is a
+24-bits RGB color, stored as three contiguous bytes: the first is the red value
+(0-255), then green, then blue. Entries are stored in a contiguous byte array.
+
+The `depth` parameter specifies how many colors are present in the given
+palette. The number of color entries must be 2 ^ depth, where 1 <= depth <= 8.
+
+Example `palette` and `depth` values:
+
+ uint8_t palette[] = {
+ 0x00, 0x00, 0x00, /* entry 0: black */
+ 0xFF, 0xFF, 0xFF, /* entry 1: white */
+ 0xFF, 0x00, 0x00, /* entry 2: red */
+ 0x00, 0x00, 0xFF, /* entry 3: blue */
+ };
+ int depth = 2; /* palette has 1 << 2 (i.e. 4) entries */
+
+If `palette` is NULL, entries are taken from a default table of 256 colors. If
+`depth` < 8, the default table will be truncated to the appropriate size. The
+default table is composed of the 16 standard VGA colors, plus the 216 web-safe
+colors (all combinations of RGB with only 6 valid values per channel), plus 24
+grey colors equally spaced between black and white, excluding both.
+
+If `depth` < 0 and `palette` is not NULL, then the default table with 2 ^ -depth
+colors is used and it is stored in the array at the `palette` address.
+
+If the `loop` parameter is zero, the resulting GIF will loop forever. If it is a
+positive number, the animation will be played that number of times. If `loop`
+is negative, no looping information is stored in the GIF file (for most GIF
+viewers, this is equivalent to `loop` == 1, i.e., "play once").
+
+The ge_add_frame() function reads pixel data from a buffer and saves the
+resulting frame to the file associated with the given ge_GIF handler:
+
+ void ge_add_frame(ge_GIF *gif, uint16_t delay);
+
+The `delay` parameter specifies how long the frame will be shown, in hundreths
+of a second. For example, `delay` == 100 means "show this frame for one second"
+and `delay` == 25 means "show this frame for a quarter of a second". Note that
+short delays may not be supported by some GIF viewers: it's recommended to keep
+a minimum of `delay` == 6. If `delay` == 0, no delay information will be stored
+for the frame. This can be used when creating still (single-frame) GIF images.
+
+Pixel data is read from `gif->frame`, which points to a memory block like this:
+
+ uint8_t _frame_[gif->width * gif->height];
+
+Note that the address of `gif->frame` changes between calls to ge_add_frame()
+(*). For this reason, each frame must be written in its entirety to the current
+address, even if one only wants to change a few pixels from the last frame. The
+encoder will automatically detect the difference between two consecutive frames
+in order to minimize the size of the output.
+
+Each byte in the frame buffer represents a pixel. The value of each pixel is an
+index to a palette entry. For instance, given the example palette above, we can
+create a frame displaying a red-on-black "F" letter like this:
+
+ uint8_t pixels[] = {
+ 2, 2, 2, 2,
+ 2, 0, 0, 0,
+ 2, 0, 0, 0,
+ 2, 2, 2, 0,
+ 2, 0, 0, 0,
+ 2, 0, 0, 0,
+ 2, 0, 0, 0
+ };
+ ge_GIF *gif = ge_new_gif("F.gif", 4, 7, palette, depth, -1);
+ memcpy(gif->frame, pixels, sizeof(pixels));
+ ge_add_frame(gif, 0);
+ ge_close_gif(gif);
+
+The function ge_close_gif() finishes writting GIF data to the file associated
+with the given ge_GIF handler and does memory clean-up. This function must be
+called once after all desired frames have been added, in order to correctly save
+the GIF file. After calling this function, the ge_GIF handler cannot be used
+anymore.
+
+ void ge_close_gif(ge_GIF* gif);
+
+(*) The encoder keeps two frame buffers internally, in order to implement the
+size optimization. The address of `gif->frame` alternates between those two
+buffers after each call to ge_add_frame().
+
+
+Example
+-------
+
+See the file "example.c". It can be tested like this:
+
+$ cc -o example gifenc.c example.c
+$ ./example
+
+That should create an animated GIF named "example.gif".
+
+
+Copying
+-------
+
+All of the source code and documentation for gifenc is released into the
+public domain and provided without warranty of any kind.
