How to write BMP images in Java (Tutorial)

In this article, we will show you how to write BMP images in Java. We also have a related article covering how to read BMP files in Java.

ImageIO can write out images as BMP files but has limited control over the process or the output. So we added the ability to write out images as BMP files with JDeli. In this article, we show you how to use either JDeli or ImageIO.

How to write out an image as a BMP file in ImageIO

1. Create a File (or OutputStream) object
2. Pass image, BMP type and File (or OutputStream) object into write method

and the Java code to write BMP with ImageIO…

File file = new File("/path/to/image.bmp");

ImageIO.write(bufferedImage, "BMP", file);

How to write out an image as a BMP file with JDeli

1. Add JDeli to your class or module path. (download link to the trial jar).
2. Create a File (or OutputStream) object
3. Pass image, BMP type and File (or OutputStream) object into write method

and the Java code to write BMP with JDeli…

File file = new File("/path/to/image.bmp");

ImageIO.write(bufferedImage, "BMP", file);

JDeli.write(bufferedImage, "BMP", file);


//In JDeli you can also use a typesafe version

JDeli.write(bufferedImage, OutputFormat.BMP, file);


//or pass in a BmpEncoderOptions object for more control

BmpEncoderOptions options = new BmpEncoderOptions();

JDeli.write(bufferedImage, options, file);

// 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);
