This article lists the encoding options that can be used with BitmapEncoder. An encoding option is defined by its name, which is a string, and a value in a particular data type (Windows.Foundation.PropertyType). For information about working with images, see Create, edit, and save bitmap images.
| Name | PropertyType | Usage notes | Valid formats |
|---|---|---|---|
| ImageQuality | single | Valid values from 0 to 1.0. Higher values indicate higher quality | JPEG, JPEG-XR |
| CompressionQuality | single | Valid values from 0 to 1.0. Higher values indicate a more efficient and slower compression scheme | TIFF |
| Lossless | boolean | If this is set to true, the ImageQuality option is ignored | JPEG-XR |
| InterlaceOption | boolean | Whether to interlace the image | PNG |
| FilterOption | uint8 | Use the PngFilterMode enumeration | PNG |
| TiffCompressionMethod | uint8 | Use the TiffCompressionMode enumeration | TIFF |
| Luminance | uint32Array | An array of 64 elements containing luminance quantization constants | JPEG |
| Chrominance | uint32Array | An array of 64 elements containing chrominance quantization constants | JPEG |
| JpegYCrCbSubsampling | uint8 | Use the JpegSubsamplingMode enumeration | JPEG |
| SuppressApp0 | boolean | Whether to suppress the creation of an App0 metadata block | JPEG |
| EnableV5Header32bppBGRA | boolean | Whether to encode to a version 5 BMP which supports alpha | BMP |
