Saving image from Picturebox...

[tech]

Hi guys I am stuck on a strange one. I get an image from the camera object using apprentice and puting it into a Picturebox. But when I try and save the image using the standard Picturebox.image.save method I get an error. Can anyone shed some light on this for me?

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click

        Dim oApprentice As New Inventor.ApprenticeServerComponent

        Dim Doc As Inventor.ApprenticeServerDocument
        Doc = oApprentice.Open(oApp.ActiveDocument.FullFileName) 'oApp is defined elsewhere.

        ' Create a client view for the document, passing in the hWnd for a picture box.  
        Dim clientView As Inventor.ClientView = Doc.ClientViews.Add(PictureBox1.Handle)

        ' Get the camera that’s associated with the client view.  
        Dim cam As Inventor.Camera = clientView.Camera

        ' Define the camera.  
        cam.ViewOrientationType = ViewOrientationTypeEnum.kIsoTopLeftViewOrientation
        cam.Perspective = False

        cam.Fit()
        cam.Apply()

        clientView.Documen()

        ' Drawing the current view.  
        clientView.Update(False)

        Dim oImage As Drawing.Image
        oImage = PictureBox1.Image

        oImage.Save("c:\temp\imagefile.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

    End Sub

Hi,

could you take a look if this blog helps you?

Hi thanks for the feedback.

Yes I know about those other methods but they still use the VB6 compatibility references. In particular: Microsoft.VisualBasic.Compatibility and STDOLE.

When creating a .Net4 project in Visual Studio it warns you that that’s obsolete. So I was hoping that there is a more current way, using ,Net 4 components and libraries, to extract the images from Inventor files.??

Awaiting your feedback

Thanks

I see.

I forgot to recommend with the other blog

Hope this helps.

Thanks that could help. I am trying it now but get an error " 'ThumbnailCallback' is not declared. It may be inaccessible because of its protection level"

You can download my project here: File

At the end of the day I would like to save the image to disk and also display it in the Picturebox.

Hi,

Obviously, you have not declared the function ThumbnailCallback. As you can see from that blog, a function is declared:

// callback function for GetThumbnailImageAbort

bool ThumbnailCallback()

{

    return false;

}

I believe it is not difficult for you to convert the code to VB.NET. 

Please give it a try.

Hi

If it helps, i could never get this to work and i was more interested in the Client View rather than the thumbnail image. Especially because i couldnt always get a thumbnail and apprentice doesnt work with an in process application. In the end, i made a rectangle to go around the picturebox and wrote a routine to take a snapshot of the contents inside the rectangle. works great for me 🙂

you can do it by using the Bitmap function
