JPEG XR (JXR) / Microsoft HD Photo File Format ( HDP)

JPEG XR is the name selected by the JPEG committee for standardization of the HD Photo file format. HD Photo can be considered to be an implementation of the JPEG XR specification. The HD Photo file format is a raster file format developed by Microsoft and it is supported by the Microsoft Photo Info application. This file format is mainly used for cross-platform image exchange, especially with handhelds, PDAs and limited-capability devices. The support for JPEG XR available in Windows Imaging Component, .NET Framework (3.0 or later), Windows Vista or later, Internet Explorer, and a number of other products, LEADTOOLS supports both formats.

LEADTOOLS supports version 1.0 of this format.

This file format supports QFactor. Possible values can be a value between 2 and 255 (lossy compression), or value 0 (lossless compression).

This file format supports loading and saving JPEG XR lossy and lossless compressions.

The file format does not support multipage files.

The default extension for JPEG-XR format is: JXR.

The default extension for HDP format is: HDP.

You can read and write 16-bit grayscale. (Document and Medical Imaging toolkits)
