Display rectangle

[jloizagah]

Hi.

What I need is quite simple. I've an Image (image PDF or TIFF) displayed on a GDviewer. I select a rectangle on this GDVIewer. I want to show the portion of image selected in the GdViewer (if any) in a different Gdviewer, but I don't want to use the clipboard.

Thanks in advance...

Hi,

You can do that using a GdPictureImaging object.

Here a snippet:

Code: Select all

      Dim ImageID As Integer = Imaging1.CreateGdPictureImageFromFile("")
      GdViewer1.DisplayFromGdPictureImage(ImageID)

      'Here let user to draw a rectangle on the GdViewer

      Dim Left, Top, Width, height As Integer
      GdViewer1.GetRectCoordinatesOnDocument(Left, Top, Width, height)

      Dim ImageID2 As Integer = Imaging1.CreateClonedGdPictureImageArea(ImageID, Left, Top, Width, height)

      GdViewer2.DisplayFromGdPictureImage(ImageID2)

Other solution consists to use the clipboard using CopyRegion2Clipboard...

Kind regards,
