Cover Art: Error Enhancing Image

[Rastilyn 2]

I have been trying to get some custom overlays for resolution on my cover art without much success. Went through a few posts and moved the overlays from a custom folder to the default plugin directory and that did not seem to work either. I am running the latest beta server 4.0.9.35 currently and have also uninstalled the plugin and reinstalled. rebooted OS ans Emby server multiple times. In the logs i am seeing the following for every image it tries to enhance.

Hi there, please attach the complete log file. thanks.

[Rastilyn 2]

Sure thing. Here you go Luke.

Did you do some kind of metadata of image refresh across your whole library?

[Rastilyn 2]

Yes, I went into the movie library and refreshed the metadata telling it to replace all images.

[Luke 42077]

I would just give it time for all of that to finish and then re-evaluate.

[Rastilyn 2]

How long should i wait to expect to see changes? i have around 900 movies and the metadata refresh was done within about an hour. Looking today i can still see the same errors in the logs through out the day. 

[Luke 42077]

HI, if you remove the use of custom overlays, do you still have an issue?

[Rastilyn 2]

No, i can use the Icon's option and that works fine. The default icons are just kind of hard to see. 

It was difficult to find much on the Cover Art plugin but from what i gathered i should have them named a hdtype_SD.png,  hdtype_HD.png, and hdtype_UHD.png and they are sitting directly in the custom-overlay folder.

Hi.  Are you sure this is set properly and the images are accessible?

apologies, had some life events come up that stole my time from following up. but yes i am fairly certain that is correct. i even went as far as letting it autocomplete navigating to that folder. i have tried folders from both the local machine inside the emby folder and a folder on my NAS which i had intended to initially use.

So i spent some time digging today... figured out the issue and wanted to post for anyone in the future who comes across this. 

Turns out my overlays were too large. I made the assumption that the plugin would see the image and resize accordingly so to get the best quality i used larger images. i knocked them down to under 100x100 and everything started working as expected.

Interesting.  Thanks for reporting back.
