Version 2.13.0

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
