OpenSlide Python allows the OpenSlide library to be used from Python programs. OpenSlide provides a simple interface for reading whole-slide images, also known as virtual slides, which are high-resolution images used in digital pathology. These images can occupy tens of gigabytes when uncompressed, and so cannot be easily read using standard tools or libraries, which are designed for images that can be comfortably uncompressed into RAM. Whole-slide images are typically {multi-resolution;} OpenSlide allows reading a small amount of image data at the resolution closest to a desired zoom level.
