Plugins#
pyjpegls#
Requires pyjpegls.
pylibjpeg#
Requires pylibjpeg as well as pylibjpeg-openjpeg for JPEG 2000 compression and pylibjpeg-rle for RLE Lossless.
Known limitations
The maximum supported Bits Stored for JPEG 2000 is 24, however the results for 20-24 are very poor when using lossy compression.
pydicom#
Requires pydicom.
Known limitations
RLE Lossless: Much slower than the other plugins
