Method Details

SaveJpeg() public static method

Encodes a WriteableBitmap object into a JPEG stream, with parameters for setting the target quality of the JPEG file.

public static SaveJpeg ( this writeableBitmap, Stream outputStream, int quality ) : void
writeableBitmap	this	The WriteableBitmap object.
outputStream	Stream	The image data stream.
quality	int	This parameter represents the quality of the JPEG photo with a range between 0 and 100, with 100 being the best photo quality. We recommend that you do not fall lower than a value of 70. because JPEG picture quality diminishes significantly below that level.
return	void

writeableBitmap	this	The WriteableBitmap object.
outputStream	Stream	The image data stream.
targetWidth	int	The target width of the file.
targetHeight	int	The target height of the file.
quality	int	This parameter represents the quality of the JPEG photo with a range between 0 and 100, with 100 being the best photo quality. We recommend that you do not fall lower than a value of 70. because JPEG picture quality diminishes significantly below that level.
return	void
