PageCanvas.DrawString(String, Font, RichEditBrushBase, Rectangle, DocumentLayoutUnit) Method

Draws a custom string.

Namespace: DevExpress.XtraRichEdit.API.Layout

Assembly: DevExpress.RichEdit.v24.1.Core.dll

NuGet Packages: DevExpress.RichEdit.Core, DevExpress.Win.Navigation

Declaration

C#

public void DrawString(
    string str,
    Font font,
    RichEditBrushBase brush,
    Rectangle bounds,
    DocumentLayoutUnit unit
)

VB.NET

Public Sub DrawString(
    str As String,
    font As Font,
    brush As RichEditBrushBase,
    bounds As Rectangle,
    unit As DocumentLayoutUnit
)

Parameters

Name	Type	Description
str	String	A custom string to be drawn.
font	Font	Sets the string’s font parameters.
brush	RichEditBrushBase	The RichEditBrushBase descendant that sets the string characters’ color and thickness.
bounds	Rectangle	Gets the location and size of the string.
unit	DocumentLayoutUnit	Specifies measurement units for the string parameters.

Remarks

When you print or export documents, document objects may appear differently from the way they look on screen. To make them look the same in both outputs, set the DocumentLayoutUnit parameter to the same DocumentLayoutUnit value as the one specified for the document layout.

Note

Using this parameter is effective only if the drawn shape has coordinates and parameters represented by absolute values – coordinates represented by relative values already have the same measurement unit as the whole document layout.
