.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ZipAppend<enum_ZIPPacker_ZipAppend>` **APPEND_CREATE** = ``0``
|
|
|
|
Create a new zip archive at the given path.
|
|
|
|
.. _class_ZIPPacker_constant_APPEND_CREATEAFTER:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ZipAppend<enum_ZIPPacker_ZipAppend>` **APPEND_CREATEAFTER** = ``1``
|
|
|
|
Append a new zip archive to the end of the already existing file at the given path.
|
|
|
|
.. _class_ZIPPacker_constant_APPEND_ADDINZIP:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ZipAppend<enum_ZIPPacker_ZipAppend>` **APPEND_ADDINZIP** = ``2``
|
|
|
|
Add new files to the existing zip archive at the given path.

.. _enum_ZIPPacker_CompressionLevel:
|
|
|
|
.. rst-class:: classref-enumeration
|
|
|
|
enum **CompressionLevel**: :ref:`🔗<enum_ZIPPacker_CompressionLevel>`
|
|
|
|
.. _class_ZIPPacker_constant_COMPRESSION_DEFAULT:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`CompressionLevel<enum_ZIPPacker_CompressionLevel>` **COMPRESSION_DEFAULT** = ``-1``
|
|
|
|
Start a file with the default Deflate compression level (``6``). This is a good compromise between speed and file size.
|
|
|
|
.. _class_ZIPPacker_constant_COMPRESSION_NONE:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`CompressionLevel<enum_ZIPPacker_CompressionLevel>` **COMPRESSION_NONE** = ``0``
|
|
|
|
Start a file with no compression. This is also known as the "Store" compression mode and is the fastest method of packing files inside a ZIP archive. Consider using this mode for files that are already compressed (such as JPEG, PNG, MP3, or Ogg Vorbis files).
|
|
|
|
.. _class_ZIPPacker_constant_COMPRESSION_FAST:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`CompressionLevel<enum_ZIPPacker_CompressionLevel>` **COMPRESSION_FAST** = ``1``
|
|
|
|
Start a file with the fastest Deflate compression level (``1``). This is fast to compress, but results in larger file sizes than :ref:`COMPRESSION_DEFAULT<class_ZIPPacker_constant_COMPRESSION_DEFAULT>`. Decompression speed is generally unaffected by the chosen compression level.
|
|
|
|
.. _class_ZIPPacker_constant_COMPRESSION_BEST:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`CompressionLevel<enum_ZIPPacker_CompressionLevel>` **COMPRESSION_BEST** = ``9``
|
|
|
|
Start a file with the best Deflate compression level (``9``). This is slow to compress, but results in smaller file sizes than :ref:`COMPRESSION_DEFAULT<class_ZIPPacker_constant_COMPRESSION_DEFAULT>`. Decompression speed is generally unaffected by the chosen compression level.

The compression level used when :ref:`start_file()<class_ZIPPacker_method_start_file>` is called. Use :ref:`CompressionLevel<enum_ZIPPacker_CompressionLevel>` as a reference.

|
|
|
|

|
|
|
|
Starts writing to a file within the archive. Only one file can be written at the same time.
|
|
|
|
Must be called after :ref:`open()<class_ZIPPacker_method_open>`.
