hdrview 2.3.0 다운로드

What's Changed
Major Feature Improvements
1. Expanded file format support and metadata
- With many "traditional" image formats now starting to add HDR support, it would be silly if a program named HDRView could not display those properly. HDRView now supports JPEG-XL, HEIF/HEIC, AVIF, PNG third edition, and UltraHDR JPEG images.
- Support for loading all frames for some animated image formats: APNG (animated PNG), HEIF, AVIF, JPEG-XL
- Now uses libpng (instead of stb_image) for PNG loading and saving, to support PNG (and APNG) third edition, and better color profile and metadata support.
- HDRView now extracts and displays more metadata, including all EXIF data, and all fields in the EXR header
2. Color Management and Chromaticity
- HDRView is now fully color managed. It extracts and applies ICC profiles, chromaticities of primaries and whitepoint, and supports the recent coding-independent code points (CICP) for specifying pre-defined (HDR) color spaces.
- The detected colorspace, primaries and white point are shown in the Info window by name, numerically, plotted on a CIE chromaticity diagram, and can be modified interactively. The whitepoint adaptation mode (none, Bradford, von Kries) can be chosen.
3. Colormaps and tonemapping overhaul
- The tone mapping mode can now be chosen from Gamma, Colormap (+), and Colormap (+/-).
- The colormap modes allow choosing from a dozen or so popular colormaps (Viridis, Inferno, Turbo, etc.), including several diverging colormaps more suitable for visualizing positive/negative values.
- Added a Python script for sampling and generating colormap data.
- sRGB is no longer an option. All images are converted to the sRGB/BT.709 color gamut for display. The Gamma tonemapping value is applied in addition to the sRGB response curve.
4. UI improvements
- A new icon!
- Added horizontal and vertical image flipping.
- Added "fit selection" and "Auto fit selection" view commands.
- Pixel statistics, histogram, and watched pixel values should now all be blend-mode aware
- Added ability to load all images from a folder.
- Can now reload a file, or all loaded files
- Can "watch" loaded folders and images for changes and new files.
- New zebra-stripe mode for showing pixels clipped pixel values
Minor Updates and Fixes
- updated to newest versions of Hello ImGui and dear imgui, and ImPlot.
- made github workflow scripts more robust to package updates in github's runners
- Added some more keyboard shortcuts, and menu icons
- preliminary support for loading only some parts/channels of an image by matching against a text filter. Currently this is only used for reloading the correct part for multi-part images (since HDRView splits files with multiple parts into separate "images" shown in the interface)
