Changes Since Last Release

Here is yet another minor release, mostly following up the previous ones with small improvements and bugfixes.

Improvements

• Improved tev's new handling of the display white level:
  • tev now detects reliably whether it is in HDR or "merely" wide-gamut SDR environments. And also whether the HDR environment supports absolute or only relative brightness.
  • tev makes an informed best guess about each image's intended white level (image formats generally have no reliable metadata in absolute units, hence the "guessing" part). When in an HDR environment with absolute brightness capability, you can then optionally render each image at absolute brightness (via --white-level=image or the GUI) rather than the default relative brightness behavior.
• tev now reads HDR10 metadata, if available, and displays it in the image info window (toggle by pressing i). The metadata is purely informative and does not affect how tev actually renders/reads the image -- except that it may be used in the white level guessing process.
• tev now distinguishes between scene- and display-referred image data in that scene-referred data (like OpenEXR images) have their colors transformed without white point adaptation ("absolute colorimetric") and display-referred data (most formats based on a certain degree of guessing, in line with how major browsers work) with white point adaptation ("relative colorimetric"). This has no practical effect on 99.99% of images, because tev's previous behavior already somewhat resembled the new one with a few exceptions that are not worth getting into.
• A new --size=<width>x<height> CLI argument for specifying the tev window's initial size.

Bugfixes

• Fixed a crash when loading JPEG-XL images with certain kinds of EXIF metadata.
• Fixed IPC over Unix sockets not working on Windows
• Fixed tev's temporary files not always getting cleaned up on exit.

Released Files

• Pre-built installer (.msi) and portable binary (.exe) for Microsoft Windows
• Pre-built installers (.dmg) for macOS: one for ARM (tev.dmg) and one for Intel (tev-intel.dmg)
• Pre-built binaries (.appimage) for Linux: one for x86_64 (tev.appimage) and one for ARM (tev-arm.appimage)
• Source code of tev excluding submodules. If you would like to build tev from source, please follow the build instructions in the project readme instead.

Changes Since Last Release

Another hotfix release, this time to fix the following two issues:

• A sporadic crash on Windows when using the save file dialog
• IPC not working when running in a flatpak sandbox without network access
  • tev now uses unix sockets instead of TCP/IP when it detects that it is in a flatpak sandbox without network access.
  • Unix sockets can also be configured by passing --hostname <socket name> when the socket name contains no : symbol. This is useful when a lot of image data has to be sent to tev very quickly, because unix sockets are much faster than going through the network stack. Curiously, unix sockets even work on Windows these days. SDKs for tev's IPC protocol (like tevclient) still need to be updated with unix socket support.

Released Files

Changes Since Last Release

This is a hotfix release for incorrect color rendering of negative sRGB color values.

Two minor features are also included:

• Changed the "sRGB" tonemap label to "None" to better reflect end-to-end tonemapping behavior: colors are rendered faithfully according to the color space that the image was in -- no tonemapping is applied. This is the same as before; only the label changed.
  • The former label "sRGB" referred to an internal tonemapping step that would get reverted later in the pipeline when displaying HDR. The label only made sense in SDR situations.
  • Expanded on the "Gamma" tonemapping option and its use cases in the tooltip.
• Added a setting to override the automatically detected display reference white level.
  • Useful for displaying images with known white level at absolute brightness instead of at the system's configured relative brightness level.
  • IMPORTANT: this only works correctly when using a well-calibrated HDR display & when the OS/Compositor has HDR enabled. tev is currently unable to detect this reliably and the option might be available in wide color, SDR modes. In such situations, the setting will not work as intended.

Changes Since Last Release

New Features

• Various improvements to tev resizing itself to the loaded image's size.
  • tev no longer becomes larger than current monitor (previously was total area across all monitors).
  • tev no longer resizes itself when Auto Fit is toggled (or --auto-fit flag is set). The image is scaled to fit tev's size instead.
  • Monitor size is now correctly detected on Wayland, particularly with fractional content scaling.
• Changed resizing operations to be (power of 2) roots of two. Meaning it is easy to reach 2x, 4x, 8x, ..., 0.5x, 0.25x, 0.125x, ... scales with the mouse wheel or the +/- buttons.
• Support loading EXIF data from camera RAW image files.
• Support loading of multi-part EXR files where some of the parts fail to load (e.g. corruption).
• The Windows installer can now overwrite a previous installation of tev.

Bugfixes

• Fixed inconsistent scroll wheel handling between Wayland and the rest.
• Fixed tev -h help text for --max and --no-max flags.
• Unexpected errors in EXIF parsing no longer crash tev.
