__init__()¶

decompress()¶

Performs a foreground decompression of the named file; does not return until the decompression is complete.

Does an in-memory decompression of the indicated Ramfile. The decompressed contents are written back into the same Ramfile on completion.

get_progress()¶: Returns the ratio through the decompression step in the background.

initiate()¶

Begins a background decompression of the named file (whose filename must end in “.pz”) to a new file without the .pz extension. The source file is removed after successful completion.

Begins a background decompression from the named source file to the named destination file. The source file is removed after successful completion.

property progress → float¶: Returns the ratio through the decompression step in the background.

run()¶: Called each frame to do the next bit of work in the background task. Returns EU_ok if a chunk is completed but there is more to go, or EU_success when we’re all done. Any other return value indicates an error.
