I am using Spire.Pdf in evaluation mode to write some text to an existing PDF that has lots of other content already. I'm using method PdfCanvas.DrawString to write the text. The text appears but is pretty horrible in appearance.
A snippet of my code is:
var pdfBrush = PdfBrushes.Black;
var font = new Spire.Pdf.Graphics.PdfFont(PdfFontFamily.Helvetica, 10);
page.Canvas.DrawString(fieldValue, font, pdfBrush, new System.Drawing.PointF(field.XPosition, field.YPosition));
A partial screenshot of the resulting PDF is attached. The text added with Spire.Pdf is circled in blue and looks pretty crappy. Any suggestions?
