PdfGraphics.DrawString(String, Font, SolidBrush, PointF) Method

Draws text with the specified brush and font parameters at the specified page point.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v23.2.Drawing.dll

NuGet Package: DevExpress.Pdf.Drawing

Declaration

C#

public void DrawString(
    string text,
    Font font,
    SolidBrush brush,
    PointF point
)

VB.NET

Public Sub DrawString(
    text As String,
    font As Font,
    brush As SolidBrush,
    point As PointF
)

Parameters

Name	Type	Description
text	String	A text to draw.
font	Font	An object that defines font options.
brush	SolidBrush	An object that determines the color and texture of the drawn text.
point	PointF	A point in the world coordinate system where you can position text.

Remarks

Use the MeasureString method to calculate the size of the drawn text and a point where you can draw text.

The point parameter define the point where the text’s upper-left corner is located. Set the TextOrigin property to Baseline to make the point parameter define the point where the start of the text’s baseline is located. Set this property before the DrawString method call.

Use the UseKerning property to enable kerning in drawn text.

To draw a string on the PDF page, use one of the following methods:

PdfGraphics.AddToPageForeground, PdfGraphics.AddToPageBackground

These methods allow you to draw content on an existing page.

PdfDocumentProcessor.RenderNewPage

Draws content on a new page.

The code sample below draws text in the center of an empty page:

C#

using DevExpress.Pdf;
using DevExpress.Drawing;
//...

using (var processor = new PdfDocumentProcessor()) {
  processor.CreateEmptyDocument();
  using (PdfGraphics graphics = processor.CreateGraphics()) {

      // Obtain the first document page
      PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
      PdfRectangle pageSize = page.CropBox;

      // Specify text to draw
      string text = "PDF Document API";
      using (SolidBrush textBrush = new SolidBrush(Color.FromArgb(255, Color.DarkOrange))) {
          using (DXFont font = new DXFont("Segoe UI", 20, DXFontStyle.Regular)) {
              // Calculate text size
              SizeF textSize = graphics.MeasureString(text, font, new PdfStringFormat(), 72, 72)

              // Calculate a point where to draw text
              PointF textPoint =
                  new PointF((float)((pageSize.Width - textSize.Width) / 2), (float)((pageSize.Height - textSize.Height) / 2));

              // Draw text at the calculated point
              graphics.DrawString(text, font, textBrush, textPoint);

              // Add graphics content to the page foreground
              graphics.AddToPageForeground(page, 72, 72);
          }
      }
  }
  processor.SaveDocument("result.pdf");
}

VB.NET

Imports DevExpress.Pdf

Using processor = New PdfDocumentProcessor()
  processor.CreateEmptyDocument()

  Using graphics As PdfGraphics = processor.CreateGraphics()
    ' Obtain the first document page

    Dim pageSize As PdfRectangle = page.CropBox

    ' Specify text to draw

    Using textBrush As New SolidBrush(Color.FromArgb(255, Color.DarkOrange))
      Using font As New DXFont("Segoe UI", 20, DXFontStyle.Regular)
        ' Calculate text size
        Dim textSize As SizeF = graphics.MeasureString(text, font, New PdfStringFormat(), 72, 72)

        ' Calculate a point where to draw text
        Dim textPoint As New PointF(CSng((pageSize.Width - textSize.Width) \ 2), CSng((pageSize.Height - textSize.Height) \ 2))

        ' Draw text at the calculated point
        graphics.DrawString(text, font, textBrush, textPoint)

        ' Add graphics content to the page foreground
        graphics.AddToPageForeground(page, 72, 72)
