[BUG] RAW/DNG thumbnails are shown, but not visible in image viewer.

[tundruh]

Describe the Bug RAW/DNG images will show up in Gallery, and the thumbnails/previews are visible. However, viewing the RAW/DNG files results in a blank or blurry background depending on settings. Metadata is still visible (date, time, etc.) and details will still work, but no image.

To Reproduce Steps to reproduce the behavior:

1. Take a RAW/DNG photo using Open Camera
2. Navigate to Gallery after taking photo
3. See preview/thumbnail
4. Open image viewer
5. Blank or blurry background, no image present

Expected behavior Opening a RAW/DNG in the viewer will show the full image, identical to the JPG/other file types.

Screenshots If applicable, add screenshots to help explain your problem.

Smartphone (please complete the following information):

• Device: Google Pixel 8
• OS: Android 14 / GrapheneOS
• Version 2024071600

Additional context Other gallery apps (i.e. Aves Libre) show the RAW/DNG thumbnail as well as in the image viewer.

In my case I can see the RAW image😅, but not correctly. I will investigate but for sure it is an issue with the Subsampling Image library

@IacobIonut01 I should've provided a screenshot of what I see in case that helps. Everything else continues to work, like viewing image details and info, but in my case shows the background blur.

Edited for conciseness. Apologies, first time submitting a bug.

Can you provide a link to a test image?

@IacobIonut01 Just to clarify, you need a comparison to a working test image vs RAW?

Nah, just send over an example RAW image that causes you the problem

Sure thing.

I just used this first DNG example from this old blog site.

And the following are what I see when previewing, opening, and "focusing" (when tapping again within the viewer and the metadata and info hide temporarily).

FYI, I also just updated to the latest nightly build and still have this issue.

Thanks, I'll get back with the fix

@IacobIonut01 Just downloaded the nightly from 4 Aug, and RAW is working perfectly!

Thanks for addressing the issue, now I can delete my other gallery apps entirely. Great work, looking forward to what else you accomplish. 👍🏽

Thanks! You can close the issue now if all is good
