Declaration

C#

Shape InsertCanvas(
    DocumentPosition pos,
    SizeF size
)

VB.NET

Function InsertCanvas(
    pos As DocumentPosition,
    size As SizeF
) As Shape

Parameters

Name	Type	Description
pos	DocumentPosition	The position of the canvas anchor.
size	SizeF	An object that specifies the canvas width and height. The Document.Unit property defines the measurement units.

Returns

Type	Description
Shape	The canvas embedded in the document.

Remarks

The InsertCanvas method adds a drawing canvas to the page that contains the canvas anchor and sets its position as follows:

• the absolute horizontal position to the right of the column is 0;

• the absolute vertical position below the paragraph is 0.

Use the Shape.CanvasItems property to access the collection of canvas items. The collection’s Add methods allow you to add shapes and pictures to the canvas.

The example below adds a drawing canvas to the document.

C#

Document document = wordProcessor.Document;
// Set the measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Insert a drawing canvas.
Shape canvas = document.Shapes.InsertCanvas(document.Range.Start, new SizeF(6f, 1.5f));
// Access the collection of canvas items. 
var canvasItems = canvas.CanvasItems;
// Add a rectangle to the canvas.
var shape1 = canvasItems.AddShape(ShapeGeometryPreset.Rectangle, new RectangleF(0f, 0f, 2f, 1.5f));
shape1.Fill.SetSolidFill(Color.FromArgb(0xA4, 0xFF, 0xFF));
shape1.Line.Color = Color.DarkGray;
shape1.Line.Thickness = 2;
// Add a picture to the canvas.
var shape2 = canvasItems.AddPicture(DocumentImageSource.FromFile("Picture_Arrow.png"), new PointF(2.1f, 0.3f));
// Add a parallelogram to the canvas.
var shape3 = canvasItems.AddShape(ShapeGeometryPreset.Parallelogram, new RectangleF(3.8f, 0f, 2f, 1.5f));
shape3.Fill.SetSolidFill(Color.FromArgb(0xFF, 0xA5, 0xA5));
shape3.Line.Color = Color.DarkGray;
shape3.Line.Thickness = 2;

VB.NET

Dim document As Document = wordProcessor.Document

' Access the collection of canvas items. 
Dim canvasItems As CanvasShapeCollection = canvas.CanvasItems
' Add a rectangle to the canvas.
Dim shape1 As NestedShape = canvasItems.AddShape(ShapeGeometryPreset.Rectangle, New RectangleF(0F, 0F, 2F, 1.5F))
shape1.Fill.SetSolidFill(Color.FromArgb(&HA4, &HFF, &HFF))
shape1.Line.Color = Color.DarkGray
shape1.Line.Thickness = 2
' Add a picture to the canvas.
Dim shape2 As NestedShape = canvasItems.AddPicture(DocumentImageSource.FromFile("Picture_Arrow.png"), New PointF(2.1F, 0.3F))
' Add a parallelogram to the canvas.
Dim shape3 As NestedShape = canvasItems.AddShape(ShapeGeometryPreset.Parallelogram, New RectangleF(3.8F, 0F, 2F, 1.5F))
shape3.Fill.SetSolidFill(Color.FromArgb(&HFF, &HA5, &HA5))
shape3.Line.Color = Color.DarkGray
shape3.Line.Thickness = 2
