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: 56 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.
|
|
- Animation support.
