JpegEncoder
Ecng.Drawing
Managed baseline 8-bit JPEG encoder: YCbCr without chroma subsampling, the quantization tables of the standard scaled by a quality, and Huffman tables built for the picture being written.
Methods
Encode
public static byte[] Encode(RasterImage image, int quality, byte[] profile)result = JpegEncoder.Encode(image, quality, profile)Writes a picture as a JPEG. Pixels that are not opaque are shown over white.
- image
- The picture.
- quality
- From MinQuality to MaxQuality, on the scale of libjpeg.
- profile
- The ICC profile the colors of the picture are in; empty if it has none.
Fields
MaxQuality
public const int MaxQualityvalue = JpegEncoder.MaxQualityThe highest quality: every coefficient is kept to the nearest whole number.
MinQuality
public const int MinQualityvalue = JpegEncoder.MinQualityThe lowest quality: the coarsest quantization.
