libbpg

A library of functions for manipulating BPG image format files

BPG (Better Portable Graphics) is a image format whose 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.
