when quality or file size is an issue, to the packages collection.
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: 71 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.
