IMAGE FILE FORMAT BPG (Better portable graphics ) Aryan Gupta B sc. (GA) 1 st year


BPG 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.

Advantages of BPG::

Advantages of BPG: High compression ratio. Files are much smaller than JPEG for similar quality. Supported by most Web browsers with a small Java script decoder (zipped size: 76 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 meta data (such as EXIF) can be included.
