Changes Since Last Release

This is a hotfix release for a regression in loading DNG images with 12-15 bit JPEG data and AVIF/HEIC images with crop metadata.

The release additionally comes with slightly faster image loading by separating IO- and CPU-bound work into separate thread pools. Most noticeable on macOS.

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

New features

• Added support for the JPEG XR image format (typically used for HDR screenshots on Windows / XBOX)
• Added support for the DICOM medical image format (MRI / CT / ultrasonic scans and the likes)
• Added support for CMYK images across all image formats that support it (JXL, JXR, JPG, TIFF)
  • tev converts to RGB via ICC profile if embedded, and via (1-CMY)*(1-K) otherwise. CMYK channels are additionally kept for manual inspection.
  • Generic 5+ channel images with corresponding ICC profiles are now similarly supported.
• Added support for subsampled YCbCr TIFF images

Bugfixes & improvements

• On Wayland Linux, tev now uses FP16 framebuffers w/ linear transfer function if supported by the compositor. This results in higher bit depth and less dithering compared to before; although the improvement should be imperceptibly small for most people / monitors. (This was disabled until now because some GPU vendors only recently gained support for this.)
• There's now a GUI popup when images fail to load
• Greatly improved GUI performance if thousands of images are open simultaneously
• Layers/channels are now sorted naturally rather than alphabetically
• The tev window no longer freezes while it is being resized
• Fixed rare cases where content looked blurry on Wayland (certain fractional screen scale & compositor combos)
• Fixed a regression where TIFF images with >4 channels in contiguous format would fail to load
• Fixed premultiplied alpha handling in TIFF images (seems to require unmultiplication before linearization by convention; kind of defeats the point of premultiplication, but it is what it is, I suppose)
• Fixed incorrect gainmap orientation for JPEG images that carry EXIF or XMP orientation metadata
• Fixed AND mask in BMP images that come without an alpha channel
• Fixed small memory leak in ICC profile application
• Fixed small misalignments in the "..."-cutoff of image buttons
• Fixed occasional double-conversion to sRGB via NCLX headers with AVIF/HEIC images

Changes Since Last Release

This is a hotfix release for an edge case when loading PNG images: tev no longer ignores the sRGB metadata chunk if a gAMA chunk or cHRM chunk are present. This issue previously led to slightly wrong colors in PNG images that contained all 3 metadata chunks.

Changes Since Last Release

New features

• Added buttons to individually toggle R, G, B, and A channels (initial implementation by @PedroVillegas)
• Added optional, perceptual soft clipping to the HDR submenu. Leads to more pleasing rendering when HDR content exceeds the monitor's capabilities at the cost of color accuracy.
  • Useful when using tev as a photo viewer rather than as an analysis tool.

Bugfixes & improvements

• Fixed incorrect gamma profile on certain OS/Monitor configurations (can only affect macOS, Windows in SDR mode, and X11)
• Fixed crash when updating an unselected image via IPC
• Fixed race conditions and general breakage in the DDS loader's COM (un)initialization
