+===================

+Pillow uses a plugin model which allows users to add their own

+Here is a list of PyPI projects that offer additional plugins:
+
+* :pypi:`DjvuRleImagePlugin`: Plugin for the DjVu RLE image format as defined in the DjVuLibre docs.
+* :pypi:`heif-image-plugin`: Simple HEIF/HEIC images plugin, based on the pyheif library.
+* :pypi:`jxlpy`: Introduces reading and writing support for JPEG XL.
+* :pypi:`pillow-heif`: Python bindings to libheif for working with HEIF images.
+* :pypi:`pillow-jpls`: Plugin for the JPEG-LS codec, based on the Charls JPEG-LS implemetation. Python bindings implemented using pybind11.
+* :pypi:`pillow-jxl-plugin`: Plugin for JPEG-XL, using Rust for bindings.
+* :pypi:`pillow-mbm`: Adds support for KSP's proprietary MBM texture format.
+* :pypi:`pillow-svg`: Implements basic SVG read support. Supports basic paths, shapes, and text.
