Adjusting Font Width Only

[James Riddles]

I am working on a project to place text on a line in a PDF.  The line will have a max width of a variable amount.  I have successfully written a function to repeatedly reduce the size of the font by 0.5 points at a time, until the text fits.  Is there any way that I can affect the horizontal scaling only?  Or, perhaps the character spacing, as well?

Thanks!

Hi James, 

 

Thank you for contacting Syncfusion support. 

 

The font size reducing workaround is the right way to fit the text with in smaller bounds. And we can scale the text horizontally/vertically by using PdfGraphics.ScaleTransform. If horizontal scaling is applied to a string then the whole string will shrink compared to its regular size. we have created a simple sample for your reference, please refer the below code snippet and sample for more details. 

            //Create a new PDF document 

            PdfDocument doc = new PdfDocument(); 

 

            //Add a new page 

            PdfPage page = doc.Pages.Add(); 

 

            //input text 

            string text = "Hello World!."; 

 

            //Create new PDF font 

            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12, PdfFontStyle.Regular); 

 

            //Measure the text width. 

            float textWidth = font.MeasureString(text).Width; 

 

            //Represent the line width to fix the text. 

            float lineWidth = 30; 

 

            //Find scaling factor 

            float scale = lineWidth / textWidth; 

 

            //Save the graphics 

            page.Graphics.Save(); 

 

            //Set scaling factor 

            page.Graphics.ScaleTransform(scale,1);            

 

            //Draw the string 

            page.Graphics.DrawString(text, font, PdfBrushes.Black, PointF.Empty); 

 

            //Restore the graphics 

            page.Graphics.Restore(); 

 

            //Save the PDF document 

            doc.Save("output.pdf"); 

 

            //Close the document 

            doc.Close(true);
