class ImageStore – store and retrieve image data

Constructors

class datastore.ImageStore

Construct an ImageStore object.

Methods

ImageStore.list()

List the tags of all available images.

ImageStore.get(image_tag)

Retrieve an image from its tag. The return value is a tuple (image_data, image_type), where:

• image_data is a bytearray containing the raw pixel values of the image.

• image_type is a constant from image specifying the image format.

ImageStore.get_token(image_tag)

Returns an opaque image.ImageToken that can be passed to splashscreen.Splashscreen methods. Unlike the previous method, this call does not result in the copying of the image from flash storage into a python bytearray. The token can be passed instead. This may result in faster rendering of the splashscreen background.
