Developers can convert any Microsoft Visio document to BMP (Bitmap Image File) in C# (or in any other .NET Framework supported language e.g. VB.NET etc.) using Aspose.Diagram which is a light-weight, extensible, easy to use API and helps developers to create, manipulate and convert Microsoft Visio files to various formats on client side and server-side without any need to install Microsoft Visio or using any sort of Microsoft Office automation.
Supported Platforms
Aspose.Diagram supports both .NET and Java platforms. Please see Aspose.Diagram for .NET and Aspose.Diagram for Java for your reference.
Sample Microsoft Visio Document - VSD
For demonstration, we will convert the following sample Microsoft Visio document to BMP in C# using Aspose.Diagram for .NET. However, you can use any Microsoft Visio document of your choice inside the sample code and it will also be converted to BMP fine.
Licensing
Please note, if you will execute the code without prior setting the Aspose.Diagram license, you will get Evaluation Watermark in your output documents. For more information, please go through Licensing.
Sample Code
The following sample code converts the Microsoft Visio document to BMP by performing these steps.
- Load Microsoft Visio document to Aspose.Diagram.Diagram object.
- Specify ImageSaveOptions to set resolution for clear image.
- Save the Aspose.Diagram.Diagram object into BMP format with specified ImageSaveOptions.
// Path for input and output documents directory. | |
String dirPath = "D:/Download/"; | |
// Load the sample Microsoft Visio document inside the Aspose.Diagram.Diagram object. | |
Aspose.Diagram.Diagram dg = new Diagram(dirPath + "SampleConvertMicrosoftVisioDocumentToBMP.vsd"); | |
// Specify Image Save Options - set the resolution of your choice. | |
Aspose.Diagram.Saving.ImageSaveOptions imgOpts = new Aspose.Diagram.Saving.ImageSaveOptions(SaveFileFormat.BMP); | |
imgOpts.Resolution = 200; | |
// Save the Diagram object into BMP format with specified ImageSaveOptions. | |
dg.Save(dirPath + "OutputConvertMicrosoftVisioDocumentToBMP.bmp", imgOpts); |
Output BMP of Microsoft Visio Document by Aspose.Diagram
The following snapshot shows the Output BMP of Microsoft Visio Document generated by Aspose.Diagram with the code given above. As you can see, the BMP looks exactly same as Microsoft Visio document.
