Shippex.Label (shippex v0.18.0) View Source
Defines the struct for storing a returned Rate, along with the tracking
number, base64-encoded image and its format.
%Shippex.Label{rate: %Shippex.Rate{},
tracking_number: "ABCDEF1234",
format: :gif,
image: "iVBORw0K..."}Note that :image is always a pure base64 string, and doesn't contain common
prefixes like "data:image/gif;base64," and so on.
Currently, UPS returns GIF labels, and USPS returns PDF labels.
