How to build Weasis

Issue Tracker

• Embedded new codecs compiled for Windows 32/64-bit, Linux x86 32/64-bit and Mac OS X 64-bit.
  • jpeg-baseline, jpeg-extended and jpeg-lossless (IJG 6b)
  • jpeg-ls (CharLS 1.1.0)
  • jpeg2000 codecs (OpegJPEG 2.1.2)
• Allows to order the codecs by priority with a unique configuration for all the systems
• Supports multi-frame and multiple fragments at the same time
• DICOM send module (DICOM node configuration at the server side and/or locally)
• Export DICOM KO build in Weasis
• Export measurements and graphics into a DICOM PR or xml file
• DICOMIZER module
• Configuration in resources for series splitting rules and for displaying DICOM Attributes on the image
• Allows in preferences to adapt the stacktrace limit of the logger
• Exporting non DICOM files will allow to extract files from DICOM encapsulated document and DICOM video
• Minimal annotations mode available in Display tool
• Reading Presentation State improvement for overlay and shutter
• Apply Presentation LUT sequence
• Read DICOM image containing float or double data
• Requires Java 8
• See JIRA Release Note

• Flexible integration to HIS or PHR (see weasis-pacs-connector)
• Web based distribution (embedded in a web page or launch from an external window)
• Desktop portable distribution (Windows, Mac OS X and Linux)
• Embedded DICOM viewer (portable distribution) in CD/DVD or other portable media
• Can be configured with very low memory footprint. Do not require recent hardware.
• Multi-language support
• Configuration of preferences on server-side and client-side
• API for building custom plug-ins

• Display all kinds of DICOM files (including multiframe, enhanced, MPEG-2, MPEG-4, MIME Encapsulation, SR, PR, KOS and AU)
• Viewer for common image formats (TIFF, BMP, FlashPiX, GIF, JPEG, PNG, and PNM)
• Image manipulation (pan, zoom, windowing, presets, rotation, flip, scroll, crosshair, filtering...)
• Optimal performance for handling large images since there is no need to load the whole image data in memory at once (Uncompressed images, tiled TIFF, tiled jpeg2000 and tiled FlashPiX).
• Layouts for comparing series or studies
• Advanced series synchronization options
• Display Presentation States (GSPS) and Key Object Selection
• Create key images (Key Object Selection object)
• Support of Modality LUTs, VOI LUTs Presentation LUTs (even non-linear)
• Support of several screens, full-screen mode.
• Multiplanar reconstructions and Maximum Intensity Projection
• Display Structured Reports
• Display cross-lines
• Measurement and annotation tools
• Region statistics of pixels (Min, Max, Mean, StDev, Skewness, Kurtosis)
• SUV measurement
• Save measurements and annotations in DICOM PR or xml file
• Import CD/DVD and local DICOM files
• Export DICOM with several options (DICOMDIR, ZIP, ISO image file with Weasis, TIFF, JPEG, PNG...)
• Magnifier glass
• Native and DICOM printing

Prerequisites: JDK 8 and Maven 3
