GdPicture Imaging

[mjnaleva]

Hello,

I am trying to use the CopyToClipboard() function on the GdPictureImaging object as follows but noticed when dealing with PDFs the image copied is from somewhere else in the PDF as if the coordinates aren't matching up somewhere. Things seem to work just fine with image files though. Am I doing something wrong?

Code for opening file:
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
m_Filename = OpenFileDialog1.FileName
If m_Filename.EndsWith("pdf") Then
status = GdViewer1.DisplayFromFile(m_Filename)
m_ImageID = GdViewer1.PdfRenderPageToGdPictureImage(72, 1)
Else
m_ImageID = oGdPictureImaging.CreateGdPictureImageFromFile(m_Filename)
GdViewer1.DisplayFromGdPictureImage(m_ImageID)
End If

End If

Code for copying to clipboard using the selected area on the GdViewer object:
Dim left, top, width, height As Integer
GdViewer1.GetRectCoordinatesOnDocument(left, top, width, height)
oGdPictureImaging.CopyRegionToClipboard(m_ImageID, left, top, width, height)

Hi,

I can't reproduce your issue with only this code. Could you upload a standalone application reproducing your problem ?

Kind regards,

Hi Loic,

I attached my sample project. I just took the OCR sample project shipped with GdPicture.NET and added a Tools menu with 'Copy to Clipboard' menu item plus support to open PDF files. Please check and let me know if I am misunderstanding something with the behavior of copying a selected area on the PDF or if there is indeed an issue. Thanks!

It appears the 'Copy to Clipboard' function in the context menu for the GdViewer works so I must be missing something. Although, I noticed with PDFs the copy zoom is not at 100% like it is for images by default.

Hi again,

Here some modification to you document loading procedure:

Code: Select all

    Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
        Dim status As GdPictureStatus
        CloseCurrentImage()
        GdViewer1.ZoomMode = ViewerZoomMode.ZoomModeFitToViewer
        If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
            m_Filename = OpenFileDialog1.FileName
            If m_Filename.EndsWith("pdf", StringComparison.CurrentCultureIgnoreCase) Then
                status = GdViewer1.DisplayFromFile(m_Filename)
                m_ImageID = GdViewer1.PdfRenderPageToGdPictureImage(200, 1)
                GdViewer1.CloseDocument()
            Else
                m_ImageID = oGdPictureImaging.CreateGdPictureImageFromFile(m_Filename)
            End If
            If m_ImageID <> 0 Then GdViewer1.DisplayFromGdPictureImage(m_ImageID)
            ShowImageInfo()
        End If
    End Sub

Note: With this implementation you are limited to the first page of a PDF document.

Hope this helps,

Loïc

Thanks Loic. Works good.
