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.
