0.30.0

Features

• Rendering engine for client-side decoding of image codecs and additive blending of multiple optical paths (monochrome channels)
• Viewer methods to toggle and update blending information of individual channels

Bug fixes

• Calculation of length and area measurements in slide coordinate system

0.23.0

Features

• Introduces annotation markers and markups for configuring how ROIs are rendered as vector graphics and for displaying measurements and qualitative evaluations next to the ROI
• Implements translation interaction tool to move ROIs in their entirely along the X/Y axis of the slide
• Adds methods to activate/deactivate dragZoom, dragPan, and snap interactions for improved control of interactive visualization
• Adds method to toggle overview map

0.22.1

Improvements

• Add utilities for transformation of coordinates between total pixel matrix and slide coordinate system
• Add more unit tests for testing coordinate transformations

0.22.0

Fixes

• Remove unnecessary log message

Features

• Add Comprehensive3DSR metadata class
• Add ability to style ROIs via the addROI() and the setROIStyle() viewer methods

0.21.1

Bug fixes

• Fix addition of ROI Measurement or Qualitative Evaluation in cases where the ROI was not added via the viewer API, but was automatically added upon a draw event

0.21.0

New features

• Support for adding ROI Measurements and Qualitative Evaluations in form of DICOM SR Content Items

0.20.1

Bug fixes

0.10.2

Bug fixes

• Fixes setup of test cases

Improvements

• Maps (Column, Row) coordinates in the 2D Total Pixel Matrix to (x, y, z) coordinates in the 3D Slide Coordinate System and vice versa based on the affine transformation defined by Equation C.7.6.2.1-1

0.10.0

Bug fixes

Correctly rotate Total Pixel Matrix as well as 3D Spatial Coordinates (SCOORD) according to Image Orientation (Slide) when mapping coordinates from image to slide coordinate system and vice versa.
