Wrong size of drawn primitives

[ViterAlex]

Hi. Using simple code as below

var doc = new PdfDocument();
//Load some existing document
var lDoc = pdfController.Load();
doc.ImportPage(lDoc, 0);
var page = doc.Pages[0];
var g1 = page.Graphics;
g1.DrawLine(PdfPens.Red, 100,100,200,100);
doc.Save(sfd.FileName);
doc.Close();
lDoc.Close();

And expecting to see line of lenght = 100 pixels. But get 135. Why? I suspect there some unit conversion but can't get it
Pdfreader set to 100% view

Hi, Irfana.

I found that line in your output is also 135 pixels. I use FastStone ruler to measure pixels on screen. What tool do you use for measuring?

Hi Oleksandr,

Our Syncfusion PDF library will consider all values as points. For example, if you get a PDF document page size, it will be in points. And If you draw an image/rectangle/line on a PDF page, the input value will be considered as points. In this code snippet, line X bounds are used as 100 in point, when we convert this point to pixels, it's value is 133 pixels. We have unit conversion APIs, https://help.syncfusion.com/cr/file-formats/Syncfusion.Pdf.Graphics.PdfGraphicsUnit.html. Using these APIs, you can convert which unit type is required and compare it accordingly.

//Create a PDF unit converter instance. 

PdfUnitConvertor converter = new PdfUnitConvertor(); 

//Convert to pixel. 

float width = converter.ConvertToPixels(100, PdfGraphicsUnit.Point);
