I think you're under limit of allowed bitmap size:
Even if your total bitmap size is less then maximum allowed one of your dimensions is beyond upper limit (8191 per-side is max).
Have you considered stiching?
Hmm, so at this point I am just trying to load the image into memory and not display it. I don't really need to display it at full size. Are you saying that I can't even load the image at all?
I haven't tried stitching. It seems like a lot of effort and I was hoping I wouldn't have to do that. Additionally, the data is already stored as a single PNG file in the database so I don't know how I am going to break it up. I was hoping since I can display the embedded image at 8000px high I could do the same thing with the ByteArray.
Flash isn't even throwing an error so I can't even tell the user why the image isn't loading. Since the Loader won't load it I can't determine the image height.
Hmm, I might be listening to the wrong object. I think I need to try listening to the loaderinfo object instead. I'll try that tomorrow and post an update.
Just an update...I have confirmed that, indeed, no events are firing. This is really frustrating.
