@@ -35,6 +35,14 @@ function (`jpeg_enable_lossless()`) and cjpeg command-line argument
(`-lossless`) can be used to create a lossless JPEG image. (Decompression of (`-lossless`) can be used to create a lossless JPEG image. (Decompression of
lossless JPEG images is handled automatically.) lossless JPEG images is handled automatically.)
5. Introduced a new flag in the TurboJPEG C and Java APIs (`TJFLAG_ARITHMETIC`
and `TJ.FLAG_ARITHMETIC`, respectively) that causes the library to use
arithmetic entropy coding in JPEG images generated by compression and transform
operations. Additionally, a new transform option (`TJXOPT_ARITHMETIC` in the C
API and `TJTransform.OPT_ARITHMETIC` in the Java API) has been introduced,
allowing arithmetic entropy coding to be enabled for selected transforms in a
multi-transform operation.
