Hello all,
BLOB stands for Binarly Large object. From Wikipedia ( https://en.wikipedia.org/wiki/Binary_large_object )
A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. They can exist as persistent values inside some databases, or exist at runtime as program variables in some languages.
To sum it up, it could be a way to store picture (matricial or vector) and then render it. Useful !
