Technical note

Before you convert ETS to DDS

ETS 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. DDS 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. ETS and DDS 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

ETS to DDS Conversion

What are ETS files?

ETS files are used in virtual microscopy to store the full-resolution image data captured from digital slides. Commonly generated by Olympus slide scanners, ETS files work alongside VSI (Virtual Slide Image) files to enable detailed, zoomable viewing of high-resolution microscope images. An ETS file contains the raw image tiles that make up the actual slide content, allowing for fast, fluid navigation across large specimens in digital pathology and biomedical research.

What are DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
