Does LeadTools ver 13 patch autorotate images based on the EXIF Orientation tag?  If this is the case, is there a property that I can set to disable this function?

My code rotates images 90 degrees based on the Orientation tag (which used to work in LeadTools ver 13), but after I patched version 13 my images are rotating 180 degrees.  Is this due to the fact that my image is being autorotated internally by LeadTools control?

Thank you for contacting LEADTOOLS. LEADTOOLS will respect the orientation or view perspective flag in EXIF files. If you choose to not load the image rotated, you would have to check that flag in the file previous to loading it. If it is rotated, you would know ahead of time and could load the file accordingly.

You should only have to set RasterCodec.Options.Load.Rotated = False and it appears that property is not working correctly. I have reported this incident as 3845IDT. As soon as a patch is released, I will contact you.


______________________________
Update by moderator:
The property is working properly, but it does not mean the orientation flag in the image file gets ignored. It only means whether to allow the file to have extended view perspective (any value other than TopLeft or BottomLeft).

Whether Options.Load.Rotated is set to True or False will not change how it gets displayed by LEADTOOLS. To ignore the view perspective, set the IgnoreViewPerspective property to True before loading.
