Images mostly come out as a white screen

[COMANDLab]

Hello, sorry if this has been covered before but I haven't been able to find a resolution.

I installed Anthias using a Raspberry Pi Lite with Bullseye using this guide:
https://www.hackster.io/Salmanfarisvp/setting-up-anthias-on-raspberry-pi-for-digital-signage-9f6a1b

Anthias installs fine, I can connect via browser and can upload assets.

When I create the images I want to project, however, the screen is almost always white. I tried uploading other random JPGs i have on my computer and sometimes they'd display, and sometimes they'd show as white. I've tried playing with the resolution is raspi-config as well as messing with the JPG resolution, as well as my monitor.

Does anyone know the fix for this? I imaging this is fairly trivial but Ive been spending too much time on it so I figure i'd reach out

Thanks!

Hi @COMANDLab , I tried to reproduce the issue on my Raspberry Pi 3B+. I used the sample image from this site, it looks ok for me.

Could you please share more details -

• Your Raspberry Pi model
• OS version
• SD card model and varient
• Do you have issues while using another format like PNG or JPEG or Video files?
• Can you try an online URL like this and share an update.
• And finally, can you gather logs for further investigation - you can follow the guide here

Thanks for responding. I will gather some additional info shortly, but here are the answers to those i can answer now:
Thank you!!

Your Raspberry Pi model:
4 B
OS version

Debian Bullseye Lite installed using the raspberry pi imager
SD card model and varient
Kootion 64GB Micro SD Card Ultra Micro SDXC Memory Card U3 A1 V30
Do you have issues while using another format like PNG or JPEG or Video files?
Haven't tried any video files. But I tried PNG and JPEG and had the same issue. It seems variable as some large images i downloaded from the internet (like Starry Night) worked, while others didn't. Some smaller files worked, but others didn't. So its not a image loading time issue as far as I can tell. What seemed to work for me, is that if I generate an image using MS Powerpoint and use 220ppi as my resolution it seems to work
Can you try an online URL like this and share an update.
Will try in a few days and get back to you
And finally, can you gather logs for further investigation - you can follow the guide here
Will try in a few days

Hi @COMANDLab, Thanks for your response. Looking forward to hearing your feedback on the image link I shared and log's for further investigation.

Can you also share with me the image file you used for testing? Thanks.

I am having the same issue. I am working on a Mac so I don't think I have options to change the registry for how powerpoint saves the slides. When I save slides from power point as images I have an option to set the resolution in pixels. I have spent hours trying out different resolutions and found that anything over 3603x2027 makes the screen go fully white. Anything I export that is 3603x2027 and lower works but does not fill my screen (since it is a 4k screen). I have also tried exporting images from Adobe indesign but I still get the same white screen. I am using a Raspberry pi4 with a 4K monitor (also same thing on a 4K Visio TV). I used the same installation method as the original poster.

A PR (#1894) that fixes white screen issues was already merged.

• See the following comment for steps on how to update Anthias: Certain Websites Crash into White Screen. Websites do not continuously play. #1879 (comment), but make sure to backup your data first.
• Go to the web UI > Settings > Get Backup. An archive file will be downloaded; for example, screenly-backup-2024-05-15T19-02-50.tar.gz.
• You can also duplicate the entire micro-SD card for safety measures, before updating.
