qv 5.1 is released
This release improves integration into desktop environments.
News
qv 5.0 is released
This release follows the rename of libtad to libtgd.
qv 4.5 is released
This release adds support for Qt6. You can still use Qt5 by setting QV_USE_QT5=ON in CMake.
Furthermore, a problem with parallel computation of statistics and histograms was fixed, and the
statistics overlay now shows the number of invalid values in the current channel (i.e. not-a-number or infinity values).
qv 4.4 is released
This release enables deep color output (30 bits) on systems that support it,
and vastly improves the handling of video files when used with libtad ≥ 2.3:
they are now shown instantly, decoding is hardware accelerated by default, and
jumping between different frames is faster than before.
qv 4.3 is released
This release fixes a few problems with color space handling under certain conditions and improves grid rendering.
qv 4.2 is released
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
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
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
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
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
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
This version improves navigation through many files (thousands are no problem) and optimizes performance. Several bugs were fixed.
qv 2.3 is released
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
This version fixes a few bugs and improves the brightness handling for dynamic range reduction (tone mapping).
qv 2.1 is released
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 1.1 is released
This is the first useful release.
qv 2.0 is released
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.
