How to convert EMF files to SVG in Java (Tutorial)

This article shows you how to convert EMF files into SVG files using our JDeli Java Image library. We also have a related article covering how to read EMF files in Java that might interest you.

What is EMF?

EMF is a file format invented by Microsoft for the Windows platform. It is a Vector file format, which means it scales nicely if you need to resize. You can learn more about them in our post “What are the WMT and EMF image file formats?”.

The filename extension for EMF files is: .emf

Why convert EMF files to SVG

The EMF file format has been around for a long time so many Companies have a big investment in EMF files. And the EMF format is not heavily supported outside the Windows world. SVG is a very popular cross-platform format that is supported by all modern Browsers and many tools on Windows, Mac, and Linux. It is also a Vector format so converted content retains the benefits of being easily rescaled.

How to convert EMF file to SVG

1. Add JDeli to your class or module path. (download link to the trial jar).
2. Create a File (or InputStream) object for the EMF file
3. Create a File (or OutputStream) object for the converted SVG output
4. Pass the File (or OutputStream) objects into a static method

and the Java code to convert EMF to SVG…

File emfFile = new File("/path/to/emfFile.emf"));
File svgFile = new File("/path/to/svgFile.svg"));
EmfDecoder.toSVG(emfFile,svgFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(dicomImageFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(heicImageFile);

// Write an image
JDeli.write(bufferedImage, "heic", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpegImageFile);

// Write an image
JDeli.write(bufferedImage, "jpeg", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpeg2000ImageFile);

// Write an image
JDeli.write(bufferedImage, "jpx", outputStreamOrFile);

// Write an image
JDeli.write(bufferedImage, "pdf", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(pngImageFile);

// Write an image
JDeli.write(bufferedImage, "png", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(tiffImageFile);

// Write an image
JDeli.write(bufferedImage, "tiff", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(webpImageFile);

// Write an image
JDeli.write(bufferedImage, "webp", outputStreamOrFile);
