Pen is too thick for .DrawString. It's a bug

        // output the report
        context.Response.ContentType = "application/pdf";
        context.Response.AddHeader("Content-Disposition", $"attachment;filename=Invoice {dataSet.Tables[0].Rows[0]["InvoiceNumber"].ToString()}.pdf");
        MemoryStream ms = new MemoryStream();
        doc.SaveToStream(ms);
        ms.Position = 0;
        ms.CopyTo(context.Response.OutputStream);
        context.Response.Flush();
        context.Response.End();

        doc.Close();
        doc.Dispose();
        doc = null;
        ms.Dispose();
        ms = null;


The problem is this line of code is rendering BOLD text. It should be just like the fontBodyText property. Normal. not bold. But notice I am using a rectangle with word wrapping because the description can overflow one line area of the "grid".

Code: Select all

            page.Canvas.DrawString(row["Description"].ToString(), fontBodyText, penDescription, PdfBrushes.Black, rDescription, formatDescription);


penDescription is declared as such (although it's in my code near the top, I mention it again)

Code: Select all

        PdfPen penDescription = new PdfPen(PdfBrushes.Black, .00000001f);


I have tried everything under the sun here and can't find a fix.

Here is a screen shot excerpt of the problem area:

Hello,

Thank you for your inquiry,
Using PdfPen itself has a certain edge effect, but I tested your scenarios and found that the effect is much better. Which Spire.PDF version you are currently using? At the same time, you can directly use "page.Canvas.DrawString(row["Description"].ToString(), fontBodyText, PdfBrushes.Black, rDescription, formatDescription);", here are the test results from my end for your reference. If you also encounter problems using this method, just feel free to write back.

Code: Select all

       PdfDocument doc = new PdfDocument();
       PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
       PdfMargins margin = new PdfMargins();
       margin.Top = unitCvtr.ConvertUnits(0.5f, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point);
       margin.Bottom = unitCvtr.ConvertUnits(0.5f, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point);
       margin.Left = unitCvtr.ConvertUnits(0.25f, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point);
       margin.Right = unitCvtr.ConvertUnits(0.25f, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point);

       PdfSection section = doc.Sections.Add();
       section.PageSettings.Margins = margin;
       PdfNewPage page = section.Pages.Add();
       PdfTrueTypeFont fontBodyText = new PdfTrueTypeFont(new System.Drawing.Font("Arial", 9f, FontStyle.Regular));
       PdfPen penDescription = new PdfPen(PdfBrushes.Black, 0.000000001f);
       PdfStringFormat formatDescription = new PdfStringFormat();
       formatDescription.WordWrap = PdfWordWrapType.Word;
       formatDescription.Alignment = PdfTextAlignment.Left;
       //Original way
      // page.Canvas.DrawString("DescriptionSampleTest", fontBodyText, penDescription, PdfBrushes.Black, new RectangleF(10, 10, 100, 100), formatDescription);

       //Another way
       page.Canvas.DrawString("DescriptionSampleTest", fontBodyText, PdfBrushes.Black, new RectangleF(10,10,100,100), formatDescription);
       doc.SaveToFile("outAnother.pdf", Spire.Pdf.FileFormat.PDF);

I found much later on that you have an overload that doesn't use PdfPen but only PdfBrush like other calls I've made. So I adjusted by using that and it looks like normal thickness now. I think the PdfPen is unable to make the font behave like normal, adding as you said an "edge" to it.

Hello,

Thank you for your feedback,
Yes, DrawString() method supports multiple overload parameter settings, different parameter settings can be selected according to different scenarios. If some fonts do not have bold font, it can use PdfPen to simulate the bold effect.
If you encounter any other problems during use, just feel free to contact.
