PdfGraphics.DrawString(String, DXFont, DXSolidBrush, Single, Single) Method

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

Namespace: DevExpress.Pdf

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

NuGet Package: DevExpress.Pdf.Drawing

Declaration

C#

public void DrawString(
    string text,
    DXFont font,
    DXSolidBrush brush,
    float x,
    float y
)

VB.NET

Public Sub DrawString(
    text As String,
    font As DXFont,
    brush As DXSolidBrush,
    x As Single,
    y As Single
)

Parameters

Name	Type	Description
text	String	A text to draw.
font	DXFont	A DXFont object that defines the text format.
brush	DXSolidBrush	A DXSolidBrush object that determines the color and texture of the drawn text.
x	Single	The x-coordinate in the world coordinate system of a point where you can draw text.
y	Single	The y-coordinate in the world coordinate system of a point where you can draw text.

Remarks

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

The x and y parameters define the point where the text’s upper-left corner is located. Set the TextOrigin property to Baseline to make the x and y parameters 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.

Example

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

C#

using DevExpress.Pdf;
using System.Drawing;
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 (DXSolidBrush textBrush = new DXSolidBrush(Color.FromArgb(255, Color.DarkOrange)))
        {
            DXFont font = new DXFont("Segoe UI", 20, DXFontStyle.Regular)
            // Calculate text size
            SizeF textSize = graphics.MeasureString(text, font);

            // Calculate a point where to draw text
            float x = (float)((pageSize.Width - textSize.Width) / 2);
            float y = (float)((pageSize.Height - textSize.Height) / 2);

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

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

VB.NET

  processor.CreateEmptyDocument()

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

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

      ' Calculate a point where to draw text
      Dim x As Single = CSng((pageSize.Width - textSize.Width) \ 2)
      Dim y As Single = CSng((pageSize.Height - textSize.Height) \ 2)

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

      ' Add graphics content to the page foreground
      graphics.AddToPageForeground(page, 72, 72)
    End Using
  End Using
  processor.SaveDocument("result.pdf")
End Using
