Hello,

I´m working with Leadtools v15.

My problem is:

I have some people photos to prepare for identification purpose, this photos and people's information are in paper and photos are glued to the paper. Sometimes the pictures are a little rotated.

What I need is to use a rectangle to frame the photo and rotate if
necessary, for this I am using AnnRectangle the problem is that I can
not find a way to obtain the contents of the rectangle selected and then rotate.


Thanks.

Actually there is no need to use the AnnRectangle object to frame the photo. You just need to draw a region around the photo and then do the following:
- After drawing the region, get a temp raster image that contains only the photo. You can do this by using the Clone method:
+-------+
Rectangle Rect = new Rectangle(0, 0, 40, 40);
activeForm.Automation.Viewer.Image.AddRectangleToRegion(null, Rect, RasterRegionCombineMode.Set);
RasterImage Tempimage = activeForm.Automation.Viewer.Image.Clone(Rect);
+-------+

- Rotate the temp image by using the RotateCommand:
+-------+
Leadtools.ImageProcessing.RotateCommand cmd = new Leadtools.ImageProcessing.RotateCommand();
cmd.Angle = 90;
cmd.Run(Tempimage);
+-------+

- Combine the temp image with the original image using the CombineFastCommand class.

Thanks,
