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
|
|
* 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.
