Section - Site - Graphics - PDF Scaling Issues
posted

We have Infragistics 2009 v2.  Old I know, but we are upgrading soon.

 

I am using the Infragistics.Documents.Reporting.  I have looked through the knowledge base and haven't seen any bug fixes listed for this so I thought I would post it.

Consider the following Code

 

      Report rpt = new Report();
      Infragistics.Documents.Report.Section.ISection section = rpt.AddSection();
      section.PageSize = Infragistics.Documents.Report.PageSizes.Letter;
      Infragistics.Documents.Report.ISite site = section.AddSite();
      Infragistics.Documents.Report.ICanvas canvas = site.AddCanvas(0F, 0F);
      Graphics gpx = canvas.CreateGraphics();
      gpx.PageUnit = GraphicsUnit.Pixel;

At this point if you check gpx.DpiX and Y they are both 96.  PageSize is Letter.   I would think that the canvas then should be 96 * 8.5 = 816 pixels across.  This is not the case. Using the following code to draw a few lines (the pens are colored and 1 pixel wide).

      gpx.DrawLine(pRed, new Point(610, 0), new Point(610, 100));
      gpx.DrawLine(pGreen, new Point(611, 0), new Point(611, 100))
      gpx.DrawLine(pBlue, new Point(612,0), new Point(612, 100));
      gpx.DrawLine(pBlack, new Point(620, 0), new Point(620, 100));

      rpt.Publish(@"C:\InfraReport_PDF.pdf",FileFormat.PDF);

 

On the resulting PDF I can just make out the Green line at 611 and if I zoom in I can see what appears to be 1/2 the Blue line.  I would have thought that 816 would have been the right hand boundary since I created the canvas at 0,0.  I can easily put a mark at 1,1.  

 

What am I missing?  Is this a bug, or just a lack of understanding?
