Unfortunately this requires using private/undocumented APIs to register as a UWP app that can drive an HDR10 signal. You can find them online; however, this will never pass Store certification...

Did some initial prototyping just with getting the SDR/basic app running on console. I am stuck on some very opaque errors on launch/app activation of the DXRenderer component which will...

The entire process should be 64 bit including the DirectXTex and OpenEXR dependencies used for EXR loading. But perhaps there is a resolution limit somewhere - what resolution image is...

Potentially resolved by #49.

Thanks for your patience and for reporting this. I am relying on DirectXTex for RGBE decoding, and it appears that it does not implement reading PRIMARIES metadata: https://github.com/microsoft/DirectXTex/blob/main/DirectXTex/DirectXTexHDR.cpp #51 is...

Thanks for your patience and for reporting this! Tentative findings from my initial investigation: From the RGBE [file format spec](https://floyd.lbl.gov/radiance/refer/filefmts.pdf), there is an EXPOSURE header variable: >EXPOSURE >A single floating...

Attaching a quick and dirty hex-edited version of the repro image with `EXPOSURE=1.00000` [ContrastTest_0p02_1p5_3840_2160-exposure1.zip](https://github.com/13thsymphony/HDRImageViewer/files/10309533/ContrastTest_0p02_1p5_3840_2160-exposure1.zip) When loading this image, my MaxCLL histogram calculation gives 1517 nits, which is within the expected...

Sorry for the delay in responding. Unfortunately, I don't have an explanation for your reported behavior. The MaxCLL calculation DOES do a downscale, but this is based on the source/image's...

That's great to hear, let me know how it turns out!
