FAQ

SVS to CAL 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 CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
