Diagram provides support to export its content as image/svg files.
The server-side method ExportDiagram helps to export the diagram. The following code illustrates how to export the diagram as image.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
//Sets the Mode for diagram export
Mode = ExportModes.Data,
};
diagram.ExportDiagram(options);
}
}Diagram provides support to export the desired region of the diagram to desired formats.
FileName is the name of the file to be downloaded. By default, the file name is set to Diagram.
Format is to specify the type/format of the exported file. By default, the diagram is exported as .jpg format. You can export diagram to the following formats:
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
Mode = ExportModes.Data,
//Sets the format for diagram export
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}Margin specifies the amount of space that has to be left around the diagram.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
Mode = ExportModes.Data,
FileName = "diagram",
Stretch = Stretch.None,
//Sets the margin for diagram export
Margin = new DiagramMargin { Left = 10, Right = 10, Bottom = 10, Top = 10 },
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}Mode specifies whether the diagram is to be exported as files or as data (ImageURL/SVG). The exporting options are as follows:
For more information about the exporting modes, refer to Exporting Modes.
The following code example illustrates how to export the diagram as raw data.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
//Sets the mode for diagram export
Mode = ExportModes.Data,
FileName = "diagram",
Stretch = Stretch.None,
Margin = new Syncfusion.Blazor.Diagrams.MarginModel() { Left = 10, Right = 10, Bottom = 10, Top = 10 },
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}You can export any particular Region of the diagram and the region is categorized as follows.
For more information about region, refer to Regions.
The following code example illustrates how to export the region occupied by the diagram elements.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
Mode = ExportModes.Data,
FileName = "format",
Stretch = Stretch.None,
//Sets the region for diagram export
Region = DiagramRegions.Content,
Margin = new Syncfusion.Blazor.Diagrams.MarginModel() { Left = 10, Right = 10, Bottom = 10, Top = 10 },
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}Diagram provides support to export any specific region of the diagram by using Bounds.
The following code example illustrates how to export the region occupied by the diagram elements.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
//Define bounds class for export the diagram
public class exportBounds
{
public double x { get; set; }
public double y { get; set; }
public double width { get; set; }
public double height { get; set; }
}
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
Mode = ExportModes.Download,
FileName = "format",
PageHeight = 400,
PageWidth = 400,
Stretch = Stretch.None,
Region = DiagramRegions.CustomBounds,
//Sets the custom bound for diagram export
Bounds = new exportBounds() { x = 10, y = 10, width = 100, height = 100 },
Margin = new Syncfusion.Blazor.Diagrams.MarginModel() { Left = 10, Right = 10, Bottom = 10, Top = 10 },
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}Diagram provides support to export the diagram as image for Stretch option. The exported images will be clearer but larger in file size.
The following code example illustrates how to export the region occupied by the diagram elements.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Export" @onclick="@OnExport" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnExport()
{
//Sets the export option for diagram
IExportOptions options = new IExportOptions()
{
Mode = ExportModes.Data,
FileName = "region",
Stretch = Stretch.Stretch,
Region = DiagramRegions.Content,
Margin = new Syncfusion.Blazor.Diagrams.MarginModel() { Left = 10, Right = 10, Bottom = 10, Top = 10 },
Format = FileFormats.SVG
};
diagram.ExportDiagram(options);
}
}The server-side method Print helps to print the diagram as image.
| Name | Type | Description |
|---|---|---|
| region | enum | Sets the region of the diagram to be printed. |
| bounds | object | Prints any custom region of diagram. |
| stretch | enum | Resizes the diagram content to fill its allocated space and printed. |
| multiplePage | boolean | Prints the diagram into multiple pages. |
| pageWidth | number | Sets the page width of the diagram while printing the diagram into multiple pages. |
| pageHeight | number | Sets the page height of the diagram while printing the diagram into multiple pages. |
| pageOrientation | enum | Sets the orientation of the page. |
The following code example illustrates how to export the region occupied by the diagram elements.
@using Syncfusion.Blazor.Diagrams
<input type="button" value="Print" @onclick="@OnPrint" />
<SfDiagram ID="diagram" Height="600px" @ref="@diagram">
</SfDiagram>
@code{
SfDiagram diagram;
private void OnPrint()
{
//Sets the print option for diagram
IPrintOptions options = new IPrintOptions()
{
MultiplePage = true,
PageHeight = 400,
PageWidth = 400,
Region = DiagramRegions.PageSettings,
};
diagram.Print(options);
}
