Technical note

JXR to STP: what to expect from the conversion

JXR is made of pixels, so the conversion works in two steps: the image is first traced into vector outlines, and those outlines are then extruded to the height you set. The result is real geometry rather than a picture wrapped in a 3D file. Outline tracing is the mode to use here, because it returns closed shapes, and only a closed shape has an area to lift. How good the result is depends almost entirely on the JXR going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

3D Workflow

From picture to 3D model

Need a 3D STP from a flat JXR image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Script the job from the command line for pipelines and scheduled runs
  • Tune the tracing precision so the edges follow the original

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.

JXR to STP Conversion

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression.
