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,
    float x,
    float y,
    PdfStringFormat format
)

VB.NET

Public Sub DrawString(
    text As String,
    font As Font,
    brush As SolidBrush,
    x As Single,
    y As Single,
    format As PdfStringFormat
)

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.
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.
format	PdfStringFormat	An object that specifies text formatting attributes.

Remarks

Use the MeasureString method to calculate the 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.

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

C#

using DevExpress.Pdf;
using System.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 (Font font = new Font("Segoe UI", 20, FontStyle.Regular))
            {
                // Calculate text size
                SizeF textSize = graphics.MeasureString(text, font, PdfStringFormat.GenericTypographic);

                // 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, PdfStringFormat.GenericTypographic);

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

VB.NET

Imports DevExpress.Pdf
Imports System.Drawing
'...

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

  Using graphics As PdfGraphics = processor.CreateGraphics()
    ' Obtain the first document page
    Dim page As PdfPage = processor.AddNewPage(PdfPaperSize.A4)
    Dim pageSize As PdfRectangle = page.CropBox

    ' Specify text to draw
    Dim text As String = "PDF Document API"
    Using textBrush As New SolidBrush(Color.FromArgb(255, Color.DarkOrange))
      Using font As New Font("Segoe UI", 20, FontStyle.Regular)
        ' Calculate text size
        Dim textSize As SizeF = graphics.MeasureString(text, font, PdfStringFormat.GenericTypographic)

        ' 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, PdfStringFormat.GenericTypographic)

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