The values for `format`, `flags`, `compression_scheme`, and `transparency_index` match [QGF's frame descriptor block](quantum_painter_qgf#qgf-frame-descriptor), with the exception that the `delta` flag is ignored by QFF.

The _length_ describes the number of octets in the data following the block header -- a block header may specify a _length_ of `0` if no blob is specified.
