Java BMP Reader

JDeli includes a BMP Reader to read BMP images into Java. The BMP Decoder is written in 100% Java with no dependencies.

Key information:

• 100% Java solution. No dlls or dependencies on native code
• Supports Bilevel, Grayscale and RGB images

Quick start:

JDeli can automatically detect the file type and will use the BMP File Reader

BufferedImage image = JDeli.read(bmpImageFile);

or

BmpDecoder decoder = new BmpDecoder();
BufferedImage image = decoder.read(bmpData);

See the full Javadoc.

Performance comparisons:

These figures were generated using jmh (as documented on our blog) with a standard set of images (also documented). They should be easy to replicate if you wish to validate, the code is on GitHub.

The higher the number, the better.
