Functions

lv_display_t *lv_opengles_texture_create(int32_t w, int32_t h)

Create a display that flushes to an OpenGL texture If you already have a texture and want to bind it to the display, see lv_opengles_texture_create_from_texture_id

Parameters:

  • w – width in pixels of the texture

  • h – height in pixels of the texture

Returns:

the new display or NULL on failure

lv_display_t *lv_opengles_texture_create_from_texture_id(int32_t w, int32_t h, unsigned int texture_id)

Create a display that flushes to the provided OpenGL texture If you don't have a texture to bind it to the display, see lv_opengles_texture_create

Parameters:

  • w – width in pixels of the texture

  • h – height in pixels of the texture

  • texture_id – the texture LVGL will render to

Returns:

the new display or NULL on failure

unsigned int lv_opengles_texture_get_texture_id(lv_display_t *disp)

Get the OpenGL texture ID of the display

Parameters:

disp – display

Returns:

texture ID

lv_display_t *lv_opengles_texture_get_from_texture_id(unsigned int texture_id)

Get the display of an OpenGL texture if it is associated with one

Parameters:

texture_id – OpenGL texture ID

Returns:

display or NULL if there no display with that texture ID
