Sometimes we need to flip the picture (uiimage) vertically (upside down) or flip it horizontally (that is, mirroring). The following figure:
There are usually two ways.
Method One, changing the direction of the picture
1, the principle of realization
UIImage has a property called Imageorientation, which is an enumeration variable.
There is no function to flip objects in PowerPoint 2002, but setting two objects can simulate the flip of an object.
For example, the real line triangle shown in Figure 1 is flipped along the right angle AB to the dotted line, and the vertex letter C moves as follows:
Figure 1
Draw a triangle with a text box labeled with vertex letters, text boxes C and triangles, and then copy the same shape
When Microsoft developed Vista, it introduced the Aero flip and used Windows flip to quickly preview all open windows (for example, open files, folders, and documents) without having to click the taskbar.
Flip 3D displays an open window in a stack. At the top of the stack, you will see an open window. To see other windows, you can browse the stack. This feature
The rotation and rollover of pictures is also a common feature in Web projects, but this is two different concepts, the rotation of the picture is a specific angle to rotate the picture, and the flip of the picture is the content of the picture in a specific direction of the swap. The picture flips needs to write the function to implement by oneself, but the rotation picture can use directly with the Imagerotate () function which provides in the GD li
Preface:
From today onwards, this programmer began to focus on writing his own blog. Before, I collected a lot of good articles, whether from cnblog above or csdn above. I have benefited greatly from it. I think the knowledge belongs to everyone, I should also contribute my own ideas. So start with the simplest algorithm first.
I'm going to start with the string algorithm because string processing is something we often encounter in programming, such as substring, reverse string, and so o
A popular cartoon effect in Flash discussion: How to rotate or flip a flat card at a 360-degree angle. It is difficult to understand the method of this animation. It's not hard to imagine that Flash is a two-dimensional program, and it's impossible to add a three-dimensional instance unless the object is manually redrawn on the timeline. But using Flash, in all of the methods, it can't really achieve three-dimensional. Let's look at how to make a card
New Ket recently had a new employee fish, who always held an English magazine every morning and wrote some sentences in the book. Colleague Cat was interested in what Fish had written, and one day he borrowed it from fish to read it, but he couldn't understand what it meant. For example, "student." A am I ". It was later realized that the guy had flipped the order of the words in the sentence and the correct sentence would be "I am a student." Cat is not good at one by one flipping these words,

Notebook computer in the power-on state often flip screen to the notebook hurt?
1. If you're just flipping, it's perfectly fine. General notebook of the screen shaft before the factory has been tested, the life of the rotating shaft is often far more than the life of some major hardware, that is, as long as you do not often at hundreds of times per minute screen, generally until the notebook scrap will not have any problems, Although I also have enco
Do not know if this is not a new bottle of wine, in fact, flipping the page navigation is not a new idea, in the previous site has been used, but has not been a fire up, do not know will be like Ajax to regain new recognition?

Title DescriptionGiven a string, it is required to move several characters in front of the string to the end of the string, such as the string "ABCdef" before the 2 characters ' a ' and ' B ' moved to the end of the string, so that the original string into the string "Cdefab". Write a function that requires an O (n) time complexity for a string operation of length n and an O (1) space complexity.2:3-Step inversion method for analysis and solutionFor this problem, think for a different angle.Divi
In Linux use Sqlplus you will find: Backspace key can not be used normally (garbled), on the flip button can not normally display the historical function, very annoying!
In order to let the backspace bar and the rollover key in Sqlplus normal play its role, we must install a software-rlwrap
1. First, download the installation package from http://utopia.knoware.nl/~hlub/uck/rlwrap/and upload it to the Linux server
2. Extract the installation as root
Today, the result is a pure CSS3 effect--image 3D flip.See Effect: http://localhost:63342/webfront/PC/rotate.htmlThis effect is mainly the use of CSS3 transform deformation properties, and the previous effect is different, this is not an animation, so did not take the animation attribute, but the transition transition attributes. This property toggles the element between the two effects and produces a transition effect. Please see the code for details.HTML structure:1 DivID= "Content">2

There are two ways to implement a linked list flip: Create a new list, and then copy the node from the old list and use it as the head. The space complexity of O (N) in situ flip. Space Complexity of O (1)
