Method

MaplibreNativeFfiMapadd_image_source_image_async

Declaration [src] 

void
maplibre_native_ffi_map_add_image_source_image_async (
  MaplibreNativeFfiMap* self,
  const char* source_id,
  const MaplibreNativeFfiLatLng* coordinates,
  gsize coordinate_count,
  MaplibreNativeFfiPremultipliedRgba8Image* image,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Adds an image source that shows image.

coordinates are the image’s four corners, clockwise from the top left.

See mln_map_add_image_source_image in the C API reference.

It fails with these errors:

  • MAPLIBRE_NATIVE_FFI_ERROR_ALREADY_EXISTS when the style already has a source named source_id.
  • MAPLIBRE_NATIVE_FFI_ERROR_INVALID_STATE while the style isn’t loaded, as maplibre_native_ffi_map_set_style_url_async() describes.

Without callback, nothing reports whether the call succeeds.

This method completes asynchronously. Use maplibre_native_ffi_map_add_image_source_image_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
