Using RIO and latest ImageEN.

I have big images that have EXIF data ( ala Rotation the big one )

I want to take and resample the big picture down to two smaller size.

Thumb (100x???) and what we call "WEB" ... basically 800x???

Images come in with a rotation EXIF tag set.

Is there a good way to insure EXIF tags are followed and preserved through
the whole process of loading the "source" image, and creating my
two scaled down images, while preserving the RAW rotation and preserving the
EXIF tags, which happen to have the rotation EXIF tag in them.

I use something like this to scale the images down

Image.proc.Resample(800, -1, rfnearest);


Any ideas?

Hi

If you load or assign an image containing EXIF data, then it should not be affected by resampling.

Are you seeing something different?
