+==== Grossing and macroscopic ====
+{{::format_macro_gross.png?nolink&200 |}}
+Gross processing or "grossing" is the process by which pathology specimens undergo examination with the naked eye to obtain diagnostic information, as well as cutting and tissue sampling in order to prepare material for subsequent microscopic examination. ([[https://en.wikipedia.org/wiki/Gross_processing|Wikipedia]])
+In order to provide a reference and link between macroscopic and microscopic samples, a //regular// photograph is often taken of a sample before it is [[https://en.wikipedia.org/wiki/Histology#Sample_preparation|further processed]].
+PMA.core supports [[https://www.pathomation.com/formats|common file formats like JPG, JPEG, JP2, TIFF, TIF, PNG, and others]] to support these observations and incorporate them seamlessly in digital pathology applications and workflows.
 ==== Brightfield ====

We offer a mix of open source community formats ([[https://www.openmicroscopy.org|OMERO TIFF & ZARR]], [[https://www.dicomstandard.org/|[DICOM]], ...), as well as legacy ones like Olympus Webview.

 ===== Annotation formats =====

 Because a picture says more than a thousand words, oftentimes slides get annotated. Here are some examples:

+Synopic reporting a great way to structure information that was previously unstructured (from a database perspective).
 Here's a example: instead of letting a pathologist write a report in which he says that the patient's tissue shows signs of abnormally proliferating cell groups, you let him or her fill out a form with a checkbox for "TumorTissuePresent".
