PixelConverter.Rgbx

Class Overview

Subclasses of PixelConverter. These subclasses are specific to surface types where we can definitively calculate the conversions. Note that some conversions are lossy; that is, we cannot necessarily convert a value and then convert it back and wind up with the original value. For example, an rgb value that has an alpha != 1 cannot be converted to an Xrgb pixel without losing the information in the alpha component. The conversion strategies associated with the ThreeByte* and FourByte* surface types swap the components around due to the ordering used when the bytes are stored. The low order byte of a packed-byte pixel will be the first byte stored and the high order byte will be the last byte stored. For example, the ThreeByteBgr surface type is associated with an Xrgb conversion object because the three bytes are stored as follows: pixels[0] = b; // low order byte of an Xrgb pixel pixels[1] = g; pixels[2] = r; // high order byte of an Xrgb pixel

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
