The Blur effect (blureffect) and Shadow effect (Dropshadoweffect) are two very useful and commonly used two effects, such as in the development album, you can add a blur effect to the thumbnail image of the photo, Dynamically change the size of the photo and blur the transparency to achieve a magnified transparency as you zoom in on the photo.First, fuzzy effect
BlurSince the iOS system introduced the Blur effect, that is, the so-called frosted glass, blur effect, matte effect, the big system began to race to imitate, this is a kind of effect, we now look at some diagram:These are typical blur effects, and there are many more in iOS and MIUI, which are no longer mapped.RealizeThere are two main ways to achieve

In android, the effects of edge Blur are implemented through BlurMaskFilter, which defines an edge Blur radius and Blur effect (Blur ).
Blur has four Blur
Blur (blur) filters are used to soften a selection or image, and to dilute the boundaries of different colors in an image to mask the defect or create special effects.
1, Motion Blur (dynamic blur filter)
Function: Blur the image in the specified direction (-360 degree
First, install the PILPIL is the Python Imaging library abbreviation for processing pictures. PIL has a Gaussian blur processing class, but there is a bug (the latest 1.1.7bug still exists), that is, the fuzzy radius of the dead is 2, cannot be set. On the 160th line of source imagefilter.py:So, we can change it here by ourselves OK.Project Address: http://www.pythonware.com/products/pil/Second, the revised CodeThe code is as follows:#-*-coding:utf-8-
Many WIN8 systems prefer to install using 360 browser, when using the browser will inevitably encounter some problems. Recently, WIN8 system users reflect, open 360 browser found the text on the page became blurred, some text can not see clearly. But do not know what is the cause, how to do? Is there any way to solve this problem? In fact, the solution is very simple, the following small series of WIN8 system open 360 browser found the Web page font blur

More worrying is that hackers or curious users can now easily get a variety of reverse engineering tools. Microsoft itself provides an MSIL disassembler, called ILDASM, free of charge, and there is a source code open. NET Decompile tool Anakrino; and, of course, many other vendors offer a commercialized reverse-engineering tool.
First, modify the variable name
The most effective way to prevent the threat of such reverse engineering is to blur it. (A

Gaussian Blur is an image fuzzy filter that calculates the transformation of each pixel in an image with a normal distribution. N-dimensional normal distribution equation is
In a two-dimensional space defined as
where R is the fuzzy radius (r2 = u2 + v2), Σ is the standard deviation of the normal distribution. In a two-dimensional space, the contours of the surface generated by this formula are concentric circles that begin

Image surface blur is a new fun
I have been working on the implementation of Image Blur effects on android a few days ago!
I can't find a method until I can see that others call JNI, but I am not familiar with JNI!
I have to start from scratch! Here we will not talk about JNI platform construction, but only about the key code of JNI. I will share the specific project with you!
I did not find C ++ to blur images in JNI, so I had to write C
If you don't have the financial ability to buy a big aperture lens, you can play with the blur filter in Photoshop. Lens blur Filter is a very interesting filter, it can well simulate the depth of the lens effect. Do the lens blur to do layer mask or channel mask, otherwise and other fuzzy no difference. Below use two scenery photograph examples to explain lens
The recent project design needs to use a slightly more blurred picture, so I went to Baidu search, treatment is probably the use of the Artifact PS (Flowers thousand bones See more, hehe). But in the eyes of a program ape, code can do everything. Below I will implement an Android Gaussian blur.Gaussian Blur: Gaussian blur (Gaussian Blur) is an image processing so

In the practice of photography, the virtual background is a common means to highlight the main body. But because the actual focal length of the consumption-level DC lens is very short, it is more difficult to realize the shallow depth and blur the background. If we want to use a consumer-level DC can also achieve the virtual background of the main effect, then, Photoshop post-processing can be useful.
The above effect picture, is using Photosho
Write in frontNow, more and more apps are using the blur effect, which is called Gaussian Blur. As we all know, fuzzy rendering on the Android platform is a fairly CPU-intensive operation, which is unavoidable once it is handled poorly. In general, given the efficiency, the best way to render a picture is to use OpenGL, followed by the use of C++/C, where Java code is the least efficient and the slowest. Bu
