    Hi,

I need help to know rotation angle after rasterCodecs load image with autorotation option is true:

here's my code:

            RasterCodecs rasterCodecs = new RasterCodecs();
            rasterCodecs.Options.Load.Rotated = true;
            IRasterImage image = rasterCodecs.Load(path);

Who can help me? :)

Hello,

This is very simple. You would use image.ViewPerspective to get the rotation angle. The ViewPerspective is of type RasterViewPerspective. RasterViewPerspective could be any of the following:

RasterViewPerspective.TopLeft
RasterViewPerspective.TopLeft90
RasterViewPerspective.TopLeft180
RasterViewPerspective.TopLeft270
RasterViewPerspective.BottomLeft
RasterViewPerspective.BottomLeft90
RasterViewPerspective.BottomLeft180
RasterViewPerspective.BottomLeft270

So you can use it like this:

if (image.ViewPerspective == RasterViewPerspective.TopLeft180)
...

For more information please refer to the "ViewPerspective Property" article of the LEADTOOLS .NET Documentation.
