In HTML5, you can determine whether the landscape screen is portrait or not.
We often encounter horizontal and vertical screen problems on mobile terminals. How should we judge or write different codes for horizontal and vertical screens.
There are two methods:I. CSS determines whether a landscape screen is portrait
Written in the same CSS
@ Media screen and (orientation: portrait) {/*
As a fan of vector materials, I believe designers like free vector backgrounds and vector graphics materials. These materials can help them quickly complete design projects, saving time, and has good results. The following are 50 + exquisite webpage vector backgrounds and vector
Vector of C ++ sequential containers, vector of sequential containers
What is container
Container, as its name implies, is a place for storing things. C ++ containers store certain data structures for data search or sorting or other special purposes. As we all know, common data structures are similar to arrays.Array, Linked listList, TreeTreeStackStack, QueueQueue, HashHash Table, SetSet, I

It is well known that SVM is a global optimal solution by solving a two-time programming problem, which leads to a lot of memory and time in practical applications. Most of the existing methods reduce support vectors by reducing training samples, which speeds up training. This article is from Li Qing and other paper "Support vector machine pre-selection based on vector projection".
The basic idea is that M
Vector
Vectors are collections of objects of the same type. Each object in the collection has a corresponding index. Vectors are often referred to as containers (container).To use vectors, you need to:
#include
The vector is a class template (classes template). C + + has functional templates and class templates. The template itself is not a function or class, it must be instantiated by the co
DescriptionAs the popularity of the West Lake in Hangzhou is further improved, the garden planning expert Yao hopes to design a new classic sightseeing line. according to the instructions of MA xiaoteng, the new landscape line is best built into a ring, if there is no condition to build a ring, the longer the building, the better.
Now N locations have been determined for construction, and m routes can be designed and their lengths have been determined
First, androidmanifest.xml configuration1. Add the android:screenorientation= "Landscape" attribute to the Androidmanifest.xml activity (activity required to disable steering) (Landscape is landscape, Portrait is Portrait)Or 2. by calling Setrequestedorientation (Activityinfo.screen_orientation_landscape) in the inside, you can set the horizontal screen, the sam
screens on different platforms, we recommend that you store images of different versions in different folders as needed.
3. Landscape Screen
The following steps are circulated on the Internet, but I used to implement this configuration through a graphical interface, which is the same in different ways. I will paste the image when I have time.
Note: Each activity has this screenorientation attribute. You must set this attribute for each activity. Yo
The oncreate method will be re-called when switching between landscape and landscape screens. You can use the following method to call the oncreate method during the switchover process. If you need to use different layout files for landscape and landscape screens, this method may not work. After I write code for testin

In the Gaussian mixture model, I mentioned the general process of feature processing:
In fact, the Gaussian mixture model completes the task of K-means, then through the Gaussian mixture model clustering, also uses the general distance based method to carry On feature encoding. No, the Gaussian mixture model is usually used in conjunction with Fisher Vector. Now let's make a brief introduction to Fisher Vector
Vector C ++, VectorVector container typeA vector container is a template class that can store any type of objects (but must be the same class object ). The vector object can efficiently add elements at runtime, and the elements in the vector are continuously stored.Vector ConstructionFunction prototype:Template Explici

You can set the paper orientation to landscape by using Control Panel \ Hardware and sound \ Devices and printers, right-clicking on the Pdffactory Pro printer, and printing preferences.After setting up AutoCAD, if AutoCAD is turned on at setup, it needs to be reopened, but the effect of printing is not what we want.This is because "pdffactory Pro" requires that the defined paper orientation be consistent with the actual paper orientation, such as a w
This tutorial is to share ps to my friends at the foot of the House to add a realistic cloud feeling to the landscape photos. the tutorials are relatively basic and the added cloud effects are extremely lifelike. we recommend that you come over, let's take a look at it. this tutorial is to share ps with my friends to add a realistic cloud-like way to the landscape photos and add a "fairy" feeling to the pic
In this tutorial, I will share with my friends how to add the sunlight beam effect to the landscape. The tutorial is really good, and the effect of the beam produced is very three-dimensional and realistic, let's take a look. this tutorial is to share with my friends how to add the sunlight beam effect to the landscape. The tutorial is really good, and the produced beam effect is very three-dimensional and
Recently, I am writing about camera.CodeThe images displayed on the screen are rotated after 90 degrees, but the photos are normal.
So I tried to rotate the screen 90 degrees, but I didn't expect it to be done.
The following describes the two methods to landscape screen (the default is landscape screen ).
1. Modify manifest. xml and add
