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 heightLV_COLOR_DEPTH 16: 4 x image width x image heightLV_COLOR_DEPTH 32: 5 x image width x image height
Example
