Quoting their website: """ BPG (Better Portable Graphics) is a new image format. Its purpose is=20=20 to=20replace the JPEG image format when quality or file size is an=20=20 issue.=20Its main advantages are: High compression ratio. Files are much smaller than JPEG for=20=20 similar=20quality. Supported by most Web browsers with a small Javascript decoder=20=20 (gzipped=20size: 55 KB). Based on a subset of the HEVC open video compression standard. Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0,=20= =20 4:2:2,=204:4:4) to reduce the losses during the conversion. An alpha=20=20 channel=20is supported. The RGB, YCgCo and CMYK color spaces are also=20=20 supported. =20 Native support of 8 to 14 bits per channel for a higher dynamic rang= e. Lossless compression is supported. Various metadata (such as EXIF, ICC profile, XMP) can be included. """ We should take a look at this new compression library and check if it=20=20 is=20usable in NX.
