Viewing PDF files in the screen

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

   Hi
Some years ago I studied the QuickPDFDLL0718.dll for processing pdf file and in this moment the printing of this files generated with a scanner was not supported because of the graphics formats inside the PDF.

I think that this problem is resolved with the actual version. On the other hand, today I need to know if I can open and view in the screen a pdf file genearated with a scanner. I'm working with Clarion 6.3 EE. My application needs to open for consulting pdf files rather than print them.

If it's possible, which are the neccesary funcions to use for doing this.

Thanks

	Here is some C# code that renders an image to a Bitmap and then that bitmap is assigned to a pictureBox control on screen. There are various RenderPageTo.. type functions and different output formats. Andrew. private void RenderPageToDC_Click(object sender, EventArgs e) { Bitmap b = new Bitmap((int)pictureBox1.Width, (int)pictureBox1.Height); using (Graphics g = Graphics.FromImage(b)) { IntPtr dc = g.GetHdc(); QP.RenderPageToDC(72, page, dc); g.ReleaseHdc(dc); pictureBox1.Image = b; } }
