Problems adding images to a PDF

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I bought this library a few days ago.
I'm new to using this library.

I am using the function to add a image file to a PDF file.

The source code is as follows:

        Dim fileName As String = "c:\source.pdf"
        Dim OutputFile As String = "c:\qpdf.pdf"

        Dim docID As Integer = QP.LoadFromFile(fileName, "")

        Dim tempimage As Integer 
        tempimage = QP.AddImageFromFile("c:\x.jpg", 0)

        QP.SelectPage(1)

        QP.SetOrigin(1)
        QP.SelectImage(tempimage )

        QP.DrawImage(0, 0, 100, 100)

        QP.SaveToFile(OutputFile)

        QP.RemoveDocument(docID)

No problem with pdf files created with adobe acrobat.

However, using Microsoft's print to pdf feature, the position and shape of the image may not be accurate.

The image is reversed and added to the wrong place

You can download a pdf file that doesn't work with the code above.

I would like to know how to add an image without converting this pdf file to pdf using acrobat again.

I love this library, thank you!

	I would suggest trying to call NormalizePage after you have selected the page and before you draw on it.
