Functions

void lv_svg_render_init(const lv_svg_render_hal_t *hal)

Initialize the SVG render.

Parameters:

hal – pointer to a structure with rendering functions

lv_svg_render_obj_t *lv_svg_render_create(const lv_svg_node_t *svg_doc)

Create a new SVG render from an SVG document.

Parameters:

svg_doc – pointer to the SVG document

Returns:

pointer to the new SVG render object

void lv_svg_render_delete(lv_svg_render_obj_t *render)

Delete an SVG render object.

Parameters:

render – pointer to the SVG render object to delete

uint32_t lv_svg_render_get_size(const lv_svg_render_obj_t *render)

Get size of render objects.

Parameters:

render – pointer to the SVG render object

Returns:

the bytes of SVG render objects

lv_result_t lv_svg_render_get_viewport_size(const lv_svg_render_obj_t *render, float *width, float *height)

Get viewport's width and height of the render object.

Parameters:

• render – pointer to the SVG render object

• width – pointer to save the width of the viewport of the SVG render object

• height – pointer to save the height of the viewport of the SVG render object

Returns:

lv_result_t, LV_RESULT_OK if success, LV_RESULT_INVALID if fail

void lv_draw_svg_render(lv_vector_dsc_t *dsc, const lv_svg_render_obj_t *render)

Render an SVG object to a vector graphics.

Parameters:

• dsc – pointer to the vector graphics descriptor

• render – pointer to the SVG render object to render

void lv_draw_svg(lv_layer_t *layer, const lv_svg_node_t *svg_doc)

Draw an SVG document to a layer.

Parameters:

• layer – pointer to the target layer

• svg_doc – pointer to the SVG document to draw
