Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

[DefaultValue(ImageSizeMode.Normal)]
[SRCategory(ReportStringId.CatBehavior)]
public ImageSizeMode Sizing { get; set; }

VB.NET

<SRCategory(ReportStringId.CatBehavior)>
<DefaultValue(ImageSizeMode.Normal)>
Public Property Sizing As ImageSizeMode

Property Value

Type	Default	Description
ImageSizeMode	Normal	One of the ImageSizeMode enumeration values that specifies how the image is displayed in the control.

Available values:

Name	Description
Normal	The image is placed in the upper-left corner of the Picture Box. The image is clipped if it does not fit into the control’s bounds.
StretchImage	The image is stretched or shrunk to fit into the current Picture Box dimensions.
AutoSize	The Picture Box size is adjusted to that of the image it contains.
CenterImage	This option is obsolete. To achieve the same result, set the XRPictureBox.Sizing property of a Picture Box to ImageSizeMode.Normal and the XRPictureBox.ImageAlignment property to ImageAlignment.MiddleCenter.
ZoomImage	The image is sized proportionally (without clipping), so that it fits best within the Picture Box dimensions. If the height-to-width ratio of the control and the image are equal, the image will be resized to exactly fit into the control’s dimensions. Otherwise, the closest matching image side (height or width) will be sized to the control, and the other side will be sized proportionally (possibly leaving empty space within the control).
Squeeze	If the Picture Box dimensions exceed that of the image it contains, the image is centered and shown full-size. Otherwise, the image is resized to fit into the control’s dimensions.
Tile	The image is replicated within the Picture Box starting from the upper-left corner. The image is clipped if it does not fit into the control’s dimensions.
Cover	The image is sized proportionally, so that it fits the Picture Box control’s entire area. If the height-to-width ratio of the control and the image are equal, the image is resized to exactly fit into the control’s dimensions. Otherwise, the least matching image side (height or width) is sized to the control, the other side is sized proportionally. The resulting image is centered as the control’s ImageAlignment property specifies. Image parts that do not fit the control are clipped.

Remarks

Use this property to specify how the image should be displayed within the XRPictureBox control.

Illustration	Description
	ImageSizeMode.Normal The image is displayed with its original dimensions.
	ImageSizeMode.StretchImage The image is stretched to fill both the control’s width and height.
	ImageSizeMode.AutoSize The control’s dimensions are auto-adjusted to the image size.
	ImageSizeMode.ZoomImage The image is proportionally resized, so that it fits the control.
	ImageSizeMode.Squeeze If the control’s dimensions exceed the image size, the image is centered and shown full-size. Otherwise, the image is resized to fit into the control’s dimensions.
	ImageSizeMode.Tile The original image is replicated within the picture control starting from the upper-left corner. The replicated image is clipped if it does not fit in the picture control which contains it.

To display the image in the middle of the control, set the XRPictureBox.Sizing property to ImageSizeMode.Normal and the XRPictureBox.ImageAlignment property to ImageAlignment.MiddleCenter.

Example

This example demonstrates how to create an XRPictureBox object and specify its properties.

C#

using DevExpress.XtraPrinting;
using DevExpress.XtraPrinting.Drawing;
using DevExpress.XtraReports.UI;
using System.Drawing;
// ...
public XRPictureBox CreateXRPictureBox()
{
    // Create an XRPictureBox instance.
    XRPictureBox xrPictureBox = new XRPictureBox();

    // Specify an image for the created XRPictureBox instance.
    xrPictureBox.ImageSource = ImageSource.FromFile("Images\\Flags\\United_States_of_America.png");
    // Uncomment these lines to get images from a data source.
    // ExpressionBinding expressionBinding = new ExpressionBinding("BeforePrint", "ImageSource", "[Picture]");
    // xrPictureBox.ExpressionBindings.Add(expressionBinding);

    // Position the picture box within a document.
    xrPictureBox.LocationF = new PointF(150F, 25F);

    // Set the picture box size.
    xrPictureBox.SizeF = new SizeF(160F, 120F);

    // Set the picture box size mode.
    xrPictureBox.Sizing = ImageSizeMode.AutoSize;

    // Specify that the image in the picture box should use the default DPI value.
    xrPictureBox.UseImageResolution = false;

    return xrPictureBox;
}
