Aperio SVS Files Load Unnecessary Macro Thumbnails and Labels Which Renders Incorrectly #17

Closed mdushkoff closed 2 weeks ago

mdushkoff commented 5 months ago

The Aperio file format specification for SVS specifically recommends stripping two components from SVS files before rendering called macro and label which refer to additional slide information and thumbnails which can mess up tiled rendering of the actual slide information:

Optionally at the end of an SVS file there may be a slide label image, which is a low resolution picture taken of the slide’s label, and/or a macro camera image, which is a low resolution picture taken of the entire slide. The label and macro images are always stripped.[^1]

I'm going to open a pull request shortly to address this, but first I have to find some publicly available data to test with that can be shared.
