========== Image font

Draw image in label or span obj with :cpp:type:lv_imgfont. This is often used to display Unicode emoji icons in text.

Supported image formats: determined by enabled LVGL :ref:image decoders <image_decoders>.

.. _lv_imgfont_usage:

Usage


Enable :c:macro:LV_USE_IMGFONT in lv_conf.h.

To create a new imgfont:

.. code-block:: c

static lv_font_t  * imgfont;
...
imgfont = lv_imgfont_create(height, path_cb, user_data);
  • height Font size.
  • path_cb A function to get the image path of a character. Pass NULL if no image should be shown, but the character itself.
  • user_data Pointer to user data.

To use the imgfont in a label, reference it: :cpp:expr:lv_obj_set_style_text_font(label, imgfont, LV_PART_MAIN)

To destroy the imgfont that is no longer used, use :cpp:expr:lv_imgfont_destroy(imgfont).
