GIF decoder

Allow using GIF images in LVGL. Based on https://github.com/lecram/gifdec

When enabled in lv_conf.h with LV_USE_GIF lv_gif_create(parent) can be used to create a gif widget.

lv_gif_set_src(obj, src) works very similarly to lv_img_set_src. As source, it also accepts images as variables (lv_img_dsc_t) or files.

Convert GIF files to C array

To convert a GIF file to byte values array use LVGL's online converter. Select "Raw" color format and "C array" Output format.

Use GIF images from file

For example:

lv_gif_set_src(obj, "S:path/to/example.gif");

Note that, a file system driver needs to be registered to open images from files. Read more about it here or just enable one in lv_conf.h with LV_USE_FS_...

Memory requirements

To decode and display a GIF animation the following amount of RAM is required:

LV_COLOR_DEPTH 8: 3 x image width x image height
LV_COLOR_DEPTH 16: 4 x image width x image height
LV_COLOR_DEPTH 32: 5 x image width x image height

Example

.. include:: ../../examples/libs/gif/index.rst

API

.. doxygenfile:: lv_gif.h
  :project: lvgl
