JNI SWIG bindings:
------------------
$ gcc -shared -fPIC -fno-strict-aliasing -O2 \
-I/path/to/your/jdk/includes \
libwebp_java_wrap.c \
-lwebp \
-o libwebp_jni.so
-------------------------------------- BEGIN PSEUDO EXAMPLE
import com.google.webp.libwebp;
import java.lang.reflect.Method;
public class libwebp_jni_example {
static {
System.loadLibrary("webp_jni");
}
/**
* usage: java -cp libwebp.jar:. libwebp_jni_example
*/
public static void main(String argv[]) {
final int version = libwebp.WebPGetDecoderVersion();
System.out.println("libwebp version: " + Integer.toHexString(version));
System.out.println("libwebp methods:");
final Method[] libwebpMethods = libwebp.class.getDeclaredMethods();
for (int i = 0; i < libwebpMethods.length; i++) {
System.out.println(libwebpMethods[i]);
}
}
}
-------------------------------------- END PSEUDO EXAMPLE
$ javac -cp libwebp.jar libwebp_jni_example.java
$ java -Djava.library.path=. -cp libwebp.jar:. libwebp_jni_example
Python SWIG bindings:
---------------------
$ python setup.py build_ext
$ python setup.py install --prefix=pylocal
-------------------------------------- BEGIN PSEUDO EXAMPLE
import glob
import sys
sys.path.append(glob.glob('pylocal/lib/python*/site-packages')[0])
from com.google.webp import libwebp
print "libwebp decoder version: %x" % libwebp.WebPGetDecoderVersion()
print "libwebp attributes:"
for attr in dir(libwebp): print attr
