./wip/libbpg, Library for BGP (Better Portable Graphics)

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 0.9.5, Package name: libbpg-0.9.5, Maintainer: pkgsrc-users

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.
