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

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 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:

Cheers and welcome here,
Ingo

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
