OpenEXR Viewer
==============
[](https://snapcraft.io/openexr-viewer)
A simple viewer for OpenEXR files with detailed metadata probing.
You can display various types of layers, automatically combines RGB,
Luminance-Chroma and Y layers.
Disclaimer
==========
This is a very early version... expect crashes, don't expect polished
piece of software ;-)
Installing
==========
Windows
-------
You can install OpenEXR Viewer from winget. Run in a terminal:
```
winget install openexr-viewer
```
Alternatively, there is an installer you can download from the release
section: https://github.com/afichet/openexr-viewer/releases
macOS
-----
There is prebuilt releases for macOS. You just need to download the
installer in the releases section and run it.
Get the releases here: https://github.com/afichet/openexr-viewer/releases
Linux
-----
For Arch Linux, you can use the AUR repository. To install, do:
```
yay -S openexr-viewer
```
For other distribution, there is a snap package available:
[](https://snapcraft.io/openexr-viewer)
```
sudo snap install openexr-viewer
```
Building
========
To build this package, you need Qt5 or greater and OpenEXR 3.0.1 or greater.
Linux
-----
If your package manager does come with an older version of OpenEXR,
you will have to build it your own:
```bash
cd /tmp
# Imath dependency
git clone https://github.com/AcademySoftwareFoundation/Imath.git
cd Imath
mkdir build
cd build
cmake ..
sudo make install
cd /tmp
# OpenEXR
git clone https://github.com/AcademySoftwareFoundation/openexr.git
cd openexr
mkdir build
cd build
cmake ..
sudo make install
```
Then, you're ready to build the software:
```bash
git clone https://github.com/afichet/openexr-viewer.git
cd openexr-viewer
mkdir build
cd build
cmake ..
make
```
Windows
-------
To help for building on Windows, there is two scripts you can use:
- `build_dependencies.bat` to build the necessary Imath and OpenEXR libraries
- `build_windows.bat` to execute after the first to build the package.
It will generate in `build/Release` a shipable binary.
You will have to edit the script `build_windows.bat` to specify your
Qt installation folder.
macOS
-----
You can install Qt from the official website and get a recent OpenEXR
release from homebrew.
```bash
brew install openexr
```
Then, you need to specify the of Qt's install when running CMake. For example:
```bash
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=~/Qt/6.1.0/clang64
```
Then, you can build the package:
```bash
make
```
