• .NET Framework 4.5+
• .NET Core 1.0+
• .NET Standard 1.1+

• Decode Huffman-coding baseline DCT-based JPEG (SOF0)
• Decode Huffman-coding extended sequential DCT-based JPEG (SOF1)
• Decode Huffman-coding progressive DCT-based JPEG (SOF2)
• Decode Huffman-coding lossless JPEG (SOF3)
• Decode arithmetic-coding sequential DCT-based JPEG (SOF9)
• Decode arithmetic-coding progressive DCT-based JPEG (SOF10)

• Encode Huffman-coding baseline DCT-based JPEG (SOF0) with optimized coding.

• Optimize an existing baseline image to use optimized Huffman coding.
