Severity: wishlist
Hi all,
By Savko Sergey I have just been pointed to the upcoming BPG image
compression library [1].
Quoting their website:
"""
BPG (Better Portable Graphics) is a new image format. Its purpose is
to replace the JPEG image format when quality or file size is an
issue. Its main advantages are:
High compression ratio. Files are much smaller than JPEG for
similar quality.
Supported by most Web browsers with a small Javascript decoder
(gzipped size: 55 KB).
Based on a subset of the HEVC open video compression standard.
Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0,
4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha
channel is supported. The RGB, YCgCo and CMYK color spaces are also
supported.
Native support of 8 to 14 bits per channel for a higher dynamic range.
Lossless compression is supported.
Various metadata (such as EXIF, ICC profile, XMP) can be included.
"""
We should take a look at this new compression library and check if it
is usable in NX.
