Fields

draw_buf: *mut lv_draw_buf_t

Target draw buffer of the layer

buf_area: lv_area_t

The absolute coordinates of the buffer

color_format: lv_color_format_t

The color format of the layer. LV_COLOR_FORMAT_…

_clip_area: lv_area_t

NEVER USE IT DRAW UNITS. USED INTERNALLY DURING DRAW TASK CREATION. The current clip area with absolute coordinates, always the same or smaller than buf_area Can be set before new draw tasks are added to indicate the clip area of the draw tasks. Therefore lv_draw_add_task() always saves it in the new draw task to know the clip area when the draw task was added. During drawing the draw units also sees the saved clip_area and should use it during drawing. During drawing the layer’s clip area shouldn’t be used as it might be already changed for other draw tasks.

phy_clip_area: lv_area_t

The physical clipping area relative to the display.

draw_task_head: *mut lv_draw_task_t

Linked list of draw tasks

parent: *mut lv_layer_t

next: *mut lv_layer_t

all_tasks_added: bool

user_data: *mut c_void
