About

JP2 WSI Converter is a virtual slide (whole-slide image) conversion application, which is designed to convert most existing scanner vendor formats into JPEG2000 in a 64-bit, multi-CPU environment, thereby enabling rapid conversion speed and integration with routine slide processing workflow.

JP2 WSI Converter produces JPEG2000 files with optimal code-stream parameterization for virtual microscopy, which we have described in our earlier study. The software is targeted for Microsoft Windows® operating systems, featuring a command line interface for batch usage and a graphical user interface with the option to process either a single file or a whole directory of files in sequence.

Documentation

Supported virtual slide scanner vendor formats for input:

  • Aperio - BigTIFF slides
  • MIRAX - MRXS slides
  • Surveyor - SWS slide workspaces
  • Hamamatsu - NDPi NanoZoomer slides

Supported general file formats for input:

  • BMP - uncompressed, 24-bit
  • JPEG - 24-bit
  • PPM - binary encoded, 24-bit
  • TIFF - 24-bit RGB with PackBits, LZW or no compression (BigTIFF supported)

Supported output file formats:

  • JPEG2000 - lossless or lossy (setting the compression ratio to 1:1 will yield a lossless compression; the actual compression ratio will be ~2:1)

JP2 WSI Converter can also be used from command line by using the following syntax:

JP2WSIConverter ...
  -i <file> -- input file (see help for supported formats)
  -o <file> -- output file (see help for supported formats)
  -c <n>    -- target compression ratio

Optional parameters:
  -t <n>    -- tile size, n*n pixels (default: no tiling)
  -m <n>    -- # of threads to be utilized (default: # of CPU cores)
  -s        -- write the processing statistics to auxiliary CSV file
  -d        -- delete the input file after successful compression
  -help     -- display help
