Read e-book online Seam Framework: Experience the Evolution of Java EE PDF

No longer a foul ebook, to be reasonable, yet from a sophisticated developer's standpoint, i have to say: "just one other tutorial". The authors take us at the traditional journey from effortless to medium complicated examples, protecting a few flooring that's generally fascinating for builders who're simply starting with Seam.

What they're (almost) no longer doing is to take the reader behind the curtain and canopy a few complex issues. Many chapters gave the impression of a blown content material of the on hand on-line documentation to me, not anything quite new, not anything rather unique.

"Seam in motion" by means of Dan Allen is the much better deal. He offers an perception from a Seam center developer's viewpoint, that is by means of way more interesting.

If i would not comprehend "Seam in Action", i'd suggest this e-book to newcomers in Seam.

I certainly don't suggest the booklet to an individual in desire of discovering solutions to complicated issues (architectures, styles, pass slicing matters in advanced company scenarios).

Callback in our activity. This allows our activity to be notified when the Surface is created, when it changes and when it is destroyed. To implement the Callback, we’ll add the following methods. public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {} public void surfaceCreated(SurfaceHolder holder) {} public void surfaceDestroyed(SurfaceHolder holder) {} CHAPTER 2: Building Custom Camera Applications To finish up, we’ll need to tell our SurfaceHolder to use this activity as the Callback handler.

In fact, this method exists for all of the parameters that have getter and setter methods and should be used to ensure that the capability requested is available before being used. Parameters object to see what effects are supported through the getSupportedColorEffect method. EFFECT_SOLARIZE. Parameters object, passing in the solarize constant. EFFECT_SOLARIZE in action. 29 30 CHAPTER 2: Building Custom Camera Applications Figure 2–3. Parameters class:  EFFECT_NONE  EFFECT_MONO  EFFECT_NEGATIVE  EFFECT_SOLARIZE  EFFECT_SEPIA  EFFECT_POSTERIZE  EFFECT_WHITEBOARD  EFFECT_BLACKBOARD  EFFECT_AQUA Similar constants exist for antibanding, flash mode, focus mode, scene mode, and white balance.

PreviewCallback: Defines a method, onPreviewFrame(byte[] data, Camera camera) , which is called when preview frames are available. A byte array that holds the current pixels of the image may be passed in. There are three different ways that this callback can be used on a Camera object. PreviewCallback with this method ensures that the onPreviewFrame method is called whenever a new preview frame is available and displayed on the screen. The data byte array that is passed into the onPreviewFrame method will most likely be in YUV format.
