Hi,
I'm using a TImageEnMView to acquire through Twain documents from my scanner.
I'm using a Canon P 215 scanner.

Despite I turn true then MIO.TwainParams.Autorotate property, documents (text documents) are not well turned.
Losts of pages are not turned, and some pages that doesnt need to be turned are.

So my question is :
- Do I need to turn some other option to enjoy autorotate ?
(I did XResolution:=150 / YResolution:=150 / AutoborderDetection:=true;
- Is there a post acquisition feature to correct the orientation afterwards ?


Thanks for your help.

Hi Thomas

AutoRotate relies on the source (scanner hardware/driver) determining the best rotation for an acquired image, so it will only work as well as your scanner

FYI, the next version of IEVision will include a GetOrientation method to automatically detect the orientation and skew of documents.
