How to read EMF files in Java with JDeli

In this post, I will show you how to read EMF files into Java as a BufferedImage. This converts the EMF file into a bitmap, so you may also be interested in our post on How to convert EMF files to SVG in Java.

What is EMF file format?

EMF file format is a public vector image format invented by Microsoft and very popular on the Windows platform. You can learn more about them in our post “What are the WMF and EMF image file formats?”.

JDeli can read EMF files directly into Java as a Buffered Image. This can be manipulated in Java and saved out to another file format.

The filename extension for EMF files is: .emf

How to read an EMF image in Java with JDeli

1. Add JDeli to your class or module path. (download the trial jar).
2. Read the EMF image into a BufferedImage

   //Read Image (can also be OutputStream or byte array)
   BufferedImage image = JDeli.read(emfFile);

Why do developers choose JDeli over free alternatives?

1. Works with newer image formats such as AVIF, HEIC, JPEG XL, WEBP (AVIF next release) that are not supported in Java.
2. Better support than alternatives for JPEG, PNG, TIFF.
3. Process images up to 3x faster than ImageIO and other Java image libraries.
4. Prevent JVM crashes caused by native code in other image libraries such as ImageIO.
5. Image security as JDeli processes images on your servers with no calls to any external system or third party library.

// 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);
