qv 4.3 is released

2021-08-25

This release fixes a few problems with color space handling under certain conditions and improves grid rendering.

qv 4.2 is released

2021-05-28

This release improves handling of data with more than 4 channels, data with alpha channels, and data containing color data in the GRAY or SRGB/GRAY color spaces. Furthermore, operations on color channels (e.g. range selection, dynamic range reduction, color mapping) now work on perceptually linear lightness (via the CIELUV color space) instead of the luminance channel of CIEXYZ.
An update is recommended.

qv 4.1 is released

2021-04-22

This release fixes a small problem where the current channel was not kept when switching between frames inside the same file, e.g. in a video.

qv 4.0 is released

2020-11-11

This release focusses on usability improvements. All functionality is now available through a classical menu and context menu system in addition to the keyboard shortcuts. Furthermore, a cyclic qualitative color map was added, useful for example for phase data.

qv 3.1 is released

2020-10-15

A few minor improvements were made. The only functional change is that the key bindings for switching between files and frames were swapped: without the shift key, you now switch files, and with the shift key, you now switch between frames inside the same file (e.g. for video files).
It is recommended to use the latest version of the tad library to benefit from its improvements.

qv 3.0 is released

2019-12-19

This version improves the info overlay and adds an option -i to set importer hints (as in the tad utility).

qv 2.6 is released

2019-12-03

This version speeds up color space conversions and the computation of statistics and histograms by using all CPU cores. Furthermore, usability was improved and a few bugs were fixed. By using libtad 0.6, support for various file formats is improved, and reloading a file works reliably now.
Update: version 2.5 introduced a color conversion bug and was replaced with version 2.6.

qv 2.4 is released

2019-11-25

This version improves navigation through many files (thousands are no problem) and optimizes performance. Several bugs were fixed.

qv 2.3 is released

2019-11-08

This version allows to manage visualization parameters either per file or globally for all files. More data types are support for sRGB color images (in particular, 16 bit). A few bugs were fixed.

qv 2.2 is released

2019-10-17

This version fixes a few bugs and improves the brightness handling for dynamic range reduction (tone mapping).

qv 2.1 is released

2019-10-11

This version adds suppor for many more input formats, including frame-by-frame analysis of video files, mainly thanks to improvements in tad 0.3. Additionally, some bugs were fixed.

qv 2.0 is released

2019-09-06

This version adds support for very large files by using a quadtree hierarchy. Usability was improved everywhere. Support for simple dynamic range reduction / tone mapping was added.

qv 1.1 is released

2019-09-06

This is the first useful release.
