Try out image4j - Image Library for Java

The image4j library allows you to read and write certain image formats in 100% pure Java.

Currently the following formats are supported:

  • BMP (Microsoft bitmap format - uncompressed; 1, 4, 8, 24 and 32 bit)
  • ICO (Microsoft icon format - 1, 4, 8, 24 and 32 bit [XP uncompressed, Vista compressed])

With the library you can easily decode your ico file

List<BufferedImage> image = ICODecoder.read(new File("input.ico"));
