pdf shows inverted images

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

   Hi,
I am testing the control and encounter a problem.

I load a PDF file, convert it's pages to images and display them.
The worsest is that i see b/w images that are inverted? They look like negatives.
I have an image of the differences. I can send it including the original pdf if you like.

QP.LoadFromFile("pdf\catalogus_novus_impexi_germanus.pdf")

QP.SetPageDimensions(800, 600)

Dim Output() As Byte = QP.RenderPageToString(96, i, 5)

Dim byteStream As IO.MemoryStream = New IO.MemoryStream(Output)

Dim Img As New BitmapImage

Img.BeginInit()
Img.StreamSource = byteStream
Img.EndInit()
Dim Pic As New Image

Pic.Source = Img
Pic.Stretch = Stretch.None

	Hi Kirill! This depends on the used compression method inside the pdf. It's a problem but it's seldom. To make QuickPDF better you should send your pdf-sample and an error-description to the official support pages. There's an upload-option, too: http://www.quickpdflibrary.com/support/support-query.php Cheers and welcome here, Ingo

	Hi Ingo, Thank you for the prompt answer. We opened incident with you about this (3048_6f2pvogcqv7lfbhq) but got that everybody is out of the office till July 27 :). The problem is that documents that we have are confidential and we cannot send them. Do you have any logging functionality in your lib to figure out this problem? I want to say that the problem is not seldom. in 50% of our images that were generated by HP and Xerox MFPs we have this issue. Thank you!

	Hi! The problem is seldom but you're working mostly on these seldom documents ;-) I fear that Debenu can't do much for you if you don't have samples. Please keep in mind that the users (like me) here in this user-user-help-forum aren't responsible for this fantastic product. We're only users (me for over seven years now). Cheers, Ingo
