Often see a friend asked how to make "Pixel brush light" (hey, I do not know whether the word is accurate), that is, do the pendant often do the kind of light point flow effect. Although I have seen a lot of related tutorials, but, personal feeling tutorials are a bit complicated and tedious; for example, if the pixel pattern is irregular, you have to do a dot of the same size, and then according to the direction of the pixel, by moving the dots one b

gradually changes the space equal dot, in order to simulate the continuous tonal, the eye then mixes these small dots into the smooth tonal, therefore any object which contains the continuous tone created in the AI can be simulated with the halftoning effect. Persistent tones are gradients, blends, and gradient meshes. In addition, the color halftone effect can also be applied to the photo.
Color is important when dealing with halftone. In a

To complete a carousel picture, the first thought should be ViewPager to use to achieve. ViewPagerThere's already a sliding function, we just let it roll itself. Plus the small dots below. So our custom controls are made up ViewPager LinearLayout of and stacked together.

computer screens. Hence the difference.The difference stems from the fact that labels are defined in point sizes (ex: Arial 10pt, etc). The graphic gurusOf the world have decided that 72 points = 1 inch. but what exactly is 1 inch on a screen? Well, that depends on the screen's DPI (DOTS-per-inch ). at 96 DPI, 1 inch = 96 dots. at 163 DPI, 1 inch = 163 dots. so
Box-shadow implementation of the DOT effect
Brief introduction
Box-shadow can theoretically generate arbitrary graphic effects, and of course, the loading effect of point points can be achieved.
Implementation principle

Implementation of loading an animation
I remember seeing an animation design above, and I tried to implement it. First, we can see that the animation is composed of two parts, one circle rotates clockwise, and the other is the linear movement of dots, there is a time difference between the dots, and the superposition of the two motion forms this rolling effect.

Pixel and millimeter conversions
The transformation also needs to know another parameter: DPI (how many dots per inch)
Number of pixels/DPI = inches
Number of inches * 25.4 = mm
There is a common way to display devices, whether they are printers or screens.
First with GetDeviceCaps (device handle, LOGPIXELSX)
Or
GetDeviceCaps (device handle, logpixelsy) gets the number of pixels per inch of the device
Note separately: px and py
One inch equals 25.4mm
When a page executes for a long time, such as a large amount of data query, and so on. You can use the following method to display prompts for the user.
Use case scenario:
Users to generate XML files to the National Bureau, and this amount of data is very large, query data for a while, write XML file also need a period of time, then how to give users a good hint that. If the escalation data is currently being analyzed. When the analysis is complete, prompt the user for "currently writing XML fil

Proper weight initialization can prevent gradients from exploding and disappearing. For Relu activation functions, weights can be initialized to:
Also known as "he initialization". For Tanh activation functions, the weights are initialized to:
Also known as "Xavier initialization". You can also use the following formula to initialize:
In the above formula, L refers to the first layer of the neural network, L-1 is the upper layer.
