Potential bug in XVweb integration

[Ardavan]

Hello world,

We recently started using Apteryx and to make workflows easier (no more exporting/importing between systems) we opted to implement the OpenDental / XVweb integration. After working with Apteryx and OpenDental support (thank you all) we were able to get the bridge up, however the doctors are complaining about the quality of the images retrieved by the bridge. Here is a screenshot of the discrepancy in quality:



And below is what Apteryx support had to say about it:

In order for us to best understand what issues may arise from pulling images from XVWeb to OpenDental, we would need to know which specific API OpenDental is using. Without that information, our developers best guess was:
“Whenever they make a request for a bitmap, they need to specify the Accept header. Currently they are most likely giving us application/json, text/plain, and */*. This makes our server give it a completely raw, unprocessed PNG.
They would need to specify image/jpeg or image/png, which will apply the proper image processing pipeline to the image.”
That may in fact fix the issue outright, but if not, then we would need to have OpenDental let you/us know which calls are being used.


So I ask the users of the forum: if you are using XVweb/OpenDental integration do your images look fine or like mine?
And I ask the OD team: What headers are being used? We have tried OD versions up to 18.3 with the same results.

It looks like we may be using application/json. I've forwarded this to the developer who coded the integration for her input and awareness.

The accept header will now use image/jpeg as of 19.1.35.0

Thank you! is it possible to backport this to 18.2 or at the very least the latest stable version?

Thanks again, you guys rock!

19.1 will be stable in the nearish future.

so does this work with server based version of apteryx?

[Ardavan]

Short answer is probably no, this is specifically for Apteryx's XVweb product. XVweb isn't cheap so you'd likely know if you have it. XVweb uses the familiar Apteryx application for capturing images however it also uses their cloud infrastructure to store images and has a nice web interface for viewing as well as an API for integration.

Its strange to call an error progress, but I'd rather a verbose error than a silent fail. After updating to the latest stable version clicking on an xvweb integrated images in the images module prompts the following error, after which the OD application closes:

Ardavan,

We were able to fix this bug in 19.1.46 and 19.2.15: "Images Module, downloading Apteryx XVWeb images caused an error sometimes."

Let us know if you have any more problems once you update.

Thanks, tested and its working!
