Hello,

I think you have quality loss because you are rendering PDF page and rotating rendered image, i.e. you do "raster rotation" of PDF page.

If you want to rotate content of PDF page without content rasterization, you can go by several ways:
1. PdfPage.RotateContentOrthogonaly method (https://www.vintasoft.com/docs/vsimagin ... onaly.html)
2. PdfPageRotateOrthogonallyCommand class (https://www.vintasoft.com/docs/vsimagin ... mmand.html)
3. PdfRotateCommand class (https://www.vintasoft.com/docs/vsimagin ... mmand.html)

Thank your for your fast answer

I loaded the image to your Vintasoft.Imaging.UI.AnnotionViewer
and want to rotate the image with annotations inside the viewer?

Hello,

In this case you need to use PdfRotateCommand class.
