viewimg is an image viewer intended to be used with OpenEXR and Radiance HDR images, however other popular image formats are supported as well. The goal of viewimg is to be a cross-platform image viewer that quickly opens OpenEXR and Radiance HDR images with the purpose of instantly seeing the image contents. There is no editing component to this application, therefore tone mapping and other HDR editing operators are not supported. The typical use case of viewimg would be to view HDR images immediately after rendering.

For both OpenEXR and Radiance HDR images, the f32 values are intensity corrected prior to casting to u8. In the case of OpenEXR images, gamma correction of 2.0 is also applied.

Installation

To install viewimg run cargo install viewimg in a terminal prompt.

Note: Vulkan must be installed on the target system in order for viewimg to work correctly. For Debian users this can be done with the command sudo apt install mesa-vulkan-drivers.

Usage

To use viewimg you can run viewimg in a terminal with the path to the image file that you wish to open:

$  viewimg ../cornell_box_denoised.hdr
