Hi
I'd like to show a JPEG progressively onscreen, while it's being loaded by IJL (Intel JPEG Library). But I can't seem to find a load-progress callback event, which would allow me to do so. It seems like IJL can't provide any feedback at all while it's loading a JPEG. Or have a overlooked something?
Cheers
Simon

Hello Simon,
IJL do not support progress callbackevents for performance reasons.

Thanks for the response.
Just to be sure: With IJL, there is no way to access the decoded JPEG image data until IJL it completely finished with the image decompression? And there's no way to cancel a decompression in progress with IJL?
Does IPP provide a JPEG decoder which hasprogress callback functionality?

yes, that is correct. Currently IPP JPEG codec do not provide such functionality (although, it is available in sources, so you can add missed features by yourself).
Another option is to submit your feature request through Intel Premier Support, so we can revise it at next version planning stage.

Vladimir
