public final class Registry extends Object
|Modifier and Type||Field and Description|
The GeoTools product name (used to register operations in JAI)
The JAITools product name (used to register operations in JAI)
|Modifier and Type||Method and Description|
Forcefully registers the specified rendered operation in the JAI registry
Register the "SampleTranscode" image operation to the operation registry of the specified JAI instance.
Allows or disallow native acceleration for the specified operation on the default JAI instance.
Allows or disallow native acceleration for the specified operation on the given JAI instance.

public static void setNativeAccelerationAllowed(String operation, boolean allowed, JAI jai)
"Affine"operation on an image with float data type, bilinear interpolation and an
ImageLayoutrendering hint cause an exception in medialib native code. Disabling the native acceleration (i.e using the pure Java version) is a convenient workaround until Sun fix the bug.
Implementation note: the current implementation assumes that factories for
native implementations are declared in the
com.sun.media.jai.mlib package, while
factories for pure java implementations are declared in the
package. It work for Sun's 1.1.2 implementation, but may change in future versions. If this
method doesn't recognize the package, it does nothing.
