Technical note

What changes when you convert SCN to HPG

SCN is made of pixels and HPG stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a HPG container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the SCN to begin with. A SCN file has a pixel count and a DPI value, and no real-world size at all. HPG is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

I regularly work with Leica SCN files in my pathology lab, and reaConverter has been a lifesaver when I need to convert them to TIFF or JPEG for collaboration. The batch processing feature saves me so much time, and the output quality remains excellent, no loss of detail even at high magnifications. The software is intuitive, and I appreciate that it preserves metadata during conversion. Highly recommended for digital pathology workflows!

reaConverter handles straightforward SCN-to-TIFF/JPEG conversions efficiently, which is helpful for sharing slides with collaborators who don’t have Leica software. The interface is user-friendly, and I’ve had no issues with standard brightfield images.

FAQ

SCN to HPG Conversion

What are SCN files?

The Leica SCN file format is a proprietary digital pathology image format used primarily by Leica Microsystems for storing high-resolution whole-slide images (WSI) generated by their slide scanners, such as those in the Leica Aperio series. These files are commonly used in histology, pathology, and biomedical research for viewing, analyzing, and sharing scanned tissue samples.

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
