finally gets a darker image. This pattern is symmetric, which means that the exchange base and the blend color get the same result.F (b) = AB, where a is the base color and B is a blend color.Filter--First, the pixel values of the two-layer images are complementary, then multiply them, and finally the complementary number. This is the opposite of the result from the multiply. It will get a brighter image.F (b) =1-(1-a) (1-b), where a is the base color and B is a blend color.Overlay-combines mul

As a reference for the realization of image recognition in the Java layer. It is best to find a hole in the JNI layer to extract the data. --leon Http://blog.csdn.net/chenji001/archive/2010/08/25/5836685.aspx In Android, if you want to process preivew data (such as face tracking), the callback function directly on the Java layer can cause frequent memory requests and copy, even with the latest Setpreviewcallbackwithbuffer functions, Memory co

The previous two blogs are all about Android 2D animations, what if you want to make a very cool 3D animation effect? Android does not provide 3D animation interface to the user, so we have to rewrite such a 3D interface animation ourselves.The interface is as follows:/* * @Title: My3danimation.java * @Description:todoThe sample code is as follows:Package Com.xjp.animator;import Com.xjp.animator.r;import An

Because the decode out of the picture is too small, smaller than the screen. As a result, the image is magnified slightly when displayed, causing the line shape to appear jagged.You can modify the size of the Getscreenimagesize method, such as 133, to make it larger.The specific changes are as follows:Modify Getscreenimagesize function in Filtershowactivity.java file about lines 507.private int getscreenimagesize () {Displaymetrics metrics = new Displaymetrics ();Display display = Getwindowmanag
