Technical note

How SVS and JXR differ in practice

SVS is a pyramidal whole-slide image: one file carries the same scanned slide at several magnifications, and the largest level can run past 100,000 pixels on a side. JXR holds a single flat picture at one resolution. That makes the magnification the decisive choice, because there is no sensible original size to fall back on here: the full-resolution level of a slide scan is larger than most image software will open at all. SVS and JXR both compress by discarding data, so this is a re-encode rather than a copy. The output is built from already-compressed pixels, and the artefacts of the first encode are carried into the second. Use a high quality setting, and convert from the original whenever you still have it.

FAQ

SVS to JXR Conversion

What are SVS files?

SVS is an image format associated with Aperio medical equipment, such as microscopes or scanscopes. Though similar with the TIFF format in terms of features, SVS has a lot less compatibility with regular image viewers and tends to have a very large size. SVS files contain multiple images in a predefined order, including a baseline tiled image, a thumbnail, intermediate "pyramid" images (made up of tiles), an optional slide label image etc.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
