How to convert PNG into BMP in Java

1. Read PNG image into Java

   BufferedImage bufferedImage = JDeli.read(new File("pngImageFile.png"));  
   

2. Process image if needed (scale, sharpen, lighten, watermark, etc)

   bufferedImage = operations.apply(BufferedImage bufferedImage); // Optional
   

3. Write out BufferedImage as BMP image file

   JDeli.write(bufferedImage, "bmp", new File("bmpImageFile.bmp"));

Export PNG to BMP in one line of code

The JDeli.convert() methods allow you to save PNG as BMP in just ONE line of code!

Using File

JDeli.convert(File inFile, File outFile);

Using InputStream and OutputStream

JDeli.convert(InputStream inputStream, OutputStream outputStream, "bmp");

Using byte[]

byte[] outputData = JDeli.convert(byte[] inputData, "bmp");

Configure Output Settings

This option allows you to specify an EncoderOptions object to configure output settings such as image compression.

JDeli.convert(File inFile, EncoderOptions outputOptions, File outfile);

Batch convert PNG to BMP from command line

Convert images from command line or bash, bat, and powershell scripts. This method can also be used to invoke JDeli from any programming language that allows you to create a child process.

java -jar jdeli.jar --convert bmp "inputFileOrDir" "outputDir"
