jbig-android

This is a JBIG codec toolkit in Android platform.

implementation detail

jbig-android is a android level wrapper above the JBIG-KIT. So it include JBIG-KIT's source code inside of it in Android's JNI level.

API document

 # encode code
    Bitmap[] bitmaps = ...;

    JbigCodec jbigCodec = JbigCodecFactory.getJbigCodec(JbigCodecFactory.CODEC.JNI_CODEC);
    byte[] jbigData = jbigCodec.encode(bitmaps);

Above code is what I said jbig encoding from multiple layers of Bitmaps.

    # jbigData is the above byte[] jbigData.

    JbigCodec jbigCodec = JbigCodecFactory.getJbigCodec(JbigCodecFactory.CODEC.JNI_CODEC);
    Bitmap[] bms = jbigCodec.decode(jbigData);

And this is the decoder part, the reverting process of above encoding part, here it decode the jbigData byte array into multiple layers of Bitmaps.

Sample app ScreenShot

Include into your project

for Android Studio or Gradle user

allprojects {
    repositories {
        jcenter()

        maven {
            url  "http://dl.bintray.com/suzp1984/maven"
        }
    }
}

Add my bintray repo into your root build.gradle.

dependencies {
  compile(group: 'org.jacob.lib.jbig', name: 'jbig-android', version: '1.0', ext: 'aar')
}

Then, add above line into your modules's dependencies scope.
