MaplibreNativeFfiMaprequest_still_image_async

Declaration [src] 

void
maplibre_native_ffi_map_request_still_image_async (
  MaplibreNativeFfiMap* self,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Renders a still image of a static or tile map.

The map’s render session draws the image once every resource that the image needs has loaded.

See mln_map_request_still_image in the C API reference.

It fails with these errors:

  • MAPLIBRE_NATIVE_FFI_ERROR_CANCELLED when the map is released before the image is done.
  • MAPLIBRE_NATIVE_FFI_ERROR_NATIVE_ERROR when the style or a resource that the image needs fails to load.

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