What is a Screenshot?

Screenshots are visual images taken by a computer and displayed on a screen or other display device. Usually screenshots can be taken by the operating system or special screenshot software, and there are also external devices such as digital cameras. Screenshots are also divided into static screenshots and dynamic screenshots. The former screenshots get a bitmap file, such as BMP, PNG, JPEG. The latter gets a video file. The purpose of screenshots is usually to show program interface icons, game scenarios, etc. in a specific state.

Windows screenshot

Windows itself has

PrtScn button + drawing tool

Regardless of whether you are using a desktop or laptop computer, there is a PrintScreen button on the keyboard, but many users do not know what it is used for. In fact, it is the "shutter" of the screen capture! When you press it, the system will automatically Save the current full-screen image to the clipboard, as long as you open any graphics processing software and paste it, you can see it, of course, you can save or edit it.

Tip: The PrintScreen key is generally located to the right of F12.

Capture full screen

Grab full screen

Grabbing a full-screen picture is the simplest operation: directly press the PrintScreen key, then open the "Draw" (also can use PS), and then press Ctrl + V. There is no technical content here, just remember to prevent some "uninvited guests" from contaminating the screen, such as the status bar of the input method, the window control buttons of "Super Hero".

This kind of screen is relatively large. The average newspaper or magazine requires 300 pixels × 300 pixels, and the maximum does not exceed 500 pixels × 500 pixels (except for special needs, of course), which needs to be adjusted in PS or ACDSee.

Grab the current window

Sometimes because of some needs, just want to capture the current active window, using the full screen capture method is obviously inappropriate. At this time, you can hold down the Alt key and press the PrintScreen key to grab only the currently active window.

Notebook screenshot

Notebook and desktop computer screenshots are not the same. With the Fn key, full screen capture fn + PrintScreen; current active window capture fn + alt + PrintScreen

Grab the cascading menu

Screenshot --- 1

In the process of writing manuscripts, it is inevitable to "draw pictures with text", especially the narration of cascading menus. A screenshot is worth a thousand words. However, if you want to grab the cascading menu using the method of grabbing the current window: the menu will disappear when you press the Alt key. At this time, you can directly press the PrintScreen key to capture the full screen, and then paste it into the graphics processing software for later processing. If you use the drawing tool, you can use the square selection tool to "select" and "cut" the required part, and then press Ctrl + E to open the "Properties" interface and set the values in "Width" and "Height" Is very small, and then you can paste and save it.

If the value in "Properties" is larger than the cut out picture, a white background will appear after pasting, so you need to decrease its value.

Capture movie footage

If you like to use WMV or RealOne to enjoy movies and want to save the wonderful pictures, then you find that the PrintScreen button snap is only the player interface, and the playback window is completely black! What should I do? It is because the DirectDraw function is called to speed up the video when playing a movie, and DirectDraw itself does not support the use of PrintScreen to capture screens. At this time, just turn "hardware acceleration" to turn off acceleration in the "Properties Settings Advanced Troubleshooting" of the desktop, and then play the movie normally and then press the PrintScreen key to capture the picture.

If you feel that the image quality after you close DirectDraw is not enough, you can use "Super Hero" or MPC to play movies or capture images. These playback software comes with screenshot function, and it is super easy to use. In addition, if you are used to using the PrintScreen key, you can expand the following branches in turn in the Registry Editor: [HKEY_LOCAL_MACHINE \ Software \ Microsoft \ DirectDraw], create a new "DWORD" value in the right window, and rename "EnablePrintScreen". Double-click it to modify its value data to "1" in the pop-up edit dialog, and click the "OK" button.

Grab the game screen

Speaking of games, I believe that many friends will be enthusiastic. How can you save your "heroic" scene in the game? In fact, you can also use the PrintScreen key to capture. The picture below is the scene of StarCraft 2 captured by this method:

Some games rely on the DirectDraw function. If DirectDraw is turned off, the game may not run, especially some stand-alone games, but the online version of the game can capture screenshots smoothly, such as StarCraft 2 above . For those tricky games, you need to use professional capture software to help.

For online war games, the exciting and fierce battle scenes are moments worth remembering forever.

Therefore, taking screenshots is very important during the game. Some games have a high-end built-in screenshot function, which makes it exciting.

Of games instantly doesn't depend on software other than games. For example, during the game, press the "F9" key on the keyboard during the game to successfully intercept the game moment.

HyperSnap

HyperSnap's screenshots can complete the several screenshot functions described above, which can capture still images, dynamic pages, DVD videos, 3D game screens, capture text, and these screenshots ^[3] can be easily completed. It also provides a variety of different screenshot methods. Area screenshots, fixed area screenshots, window screenshots, active window screenshots, full-screen screenshots, scroll area screenshots, scroll page screenshots, multi-region, free-hand screenshots, and these screenshot methods can be through the keyboard Shortcut to do it.

Screenshot provides shortcut key ^[4] operation, and hot keys can be customized.

It can also be directly linked to the printer to print out, and sent to other locations by E-mail. , You can directly set the screenshot as wallpaper.

SnagIt

Although the screen capture function of the PrintScreen key can meet our general applications, if there are slightly high requirements, there is nothing we can do, such as scrolling capture, capturing screen recordings, etc. When these requirements are needed, we must consider using professional capture software. . HyperSnap-DX can be said to be an old-fashioned software in this field, but the "new cutting-edge" SnagIt is constantly upgraded and has a great potential to surpass it. Check out some special features of SnagIt

new version of snagit

usage:

Scroll capture

In the process of capturing images, I often encounter pictures that exceed the desktop size. To view all the content, you must scroll the window. To capture all the objects, you need to use SnagIt to complete it: click "Scroll window", and click "Scroll window" on the main interface. You will see that the "Capture" button is ready on the right, but using this button is not convenient. The global shortcut key Ctrl + Shift + P has been prompted below. When the target window is the current window, just press this key combination to activate the capture function. According to the operation prompt, click the target window with the left mouse button, and then move the mouse to the scroll bar, and the scroll bar will automatically move down. When it moves to the bottom, it will automatically stop and save the capture result directly to " Capture Preview "interface, you can now edit or save directly.

Grab text

In order to prevent plagiarism, many websites have encrypted their web pages. Although there are many ways to crack its encryption, the text capture function provided by SnagIt can be described as "invincible": Click "Window Text", select "Auto Scroll Window" in "Input" in the right window, and switch to Press Ctrl + Shift + P to activate the capture function on the encrypted webpage. After clicking the left mouse button, the window will automatically scroll. After scrolling to the bottom, the result will be automatically saved in the Capture Preview. You can then save it by using a word processing software such as EmEditor.

Record screen video

The previous contacts are still pictures. What if I want to make a video of my operation and show it to others? No need to trouble DV, SnagIt can do it: click "Record a screen video", on the right Select "Screen" in "Input" in the side window, then minimize SnagIt, press Ctrl + Shift + P to activate the capture function, click "Start" in the pop-up window, and then perform the specific operation you want to record. The operation ends Then double-click the recorder icon in the taskbar to pause and call out the prompt window. Click "Finish" to complete the recording of this operation and save it as an AVI file. Click the play icon in the "Capture Preview" window to use Windows Media Player to Played.

I have only touched on some of the more distinctive features of SnagIt. For those commonly used functions, it is still simple to use the PrintScreen key. Of course, some other strange and alternative functions of SnagIt need to be tried by everyone. In addition, if you feel that the use of SnagIt is too complicated, and the function of the PrintScreen key is too simple, then you can try the QQ screenshot function.

QQ capture is also easy

Everyone on the planet knows that QQ is used for chatting. In fact, its picture capture function is also very good and practical: when you see any interesting pictures on the Internet, you can quickly use it to capture and send to chat friends, avoiding sending to Liaoyou link is suspected to be the embarrassment of QQ tail virus.

Capturing still pictures

Screenshot --- 2

Click the "Capture Screen" icon in the chat window, and a "Screenshot" prompt window will appear at the top of the screen, which shows how to do it. Now just hold down the left mouse button in the area of the screen you want to capture, carefully drag out a rectangular box, and include the required content in it. Finally, double-click the left mouse button in this rectangular box to execute the screenshot, then paste it directly into the chat window and send it to the other party. You can also open the system's own drawing, select "Paste" under "Edit", and use some drawing tools to perform Simple editing process, copy and paste to the chat window and send it to the other party.

Its upper tip: "Current pixel RGB (number)", this is the color code of the screen the mouse is pointing at! If you find a good color, you can write this number down and apply it to your own programming or web page production .

If you want to activate the QQ screen capture function, you need to open the chat window first, and the mouse can't perform other operations at the same time, which is very inconvenient. In fact, QQ also provides shortcut keys: Ctrl + Alt + A. When the desired content is in the best capture position, you can press this fast-cut key to activate this function, just press the above operation. If you are capturing content with a cascading menu, pressing this shortcut will make the menu disappear. In fact, you can press Ctrl + Alt + Shift + A first, then activate the cascading menu, release the Shift key to activate the capture function, and the operation is the same as the previous introduction.

Capture movie

In addition to the function of capturing static pictures, QQ can also capture still movies and dynamic movies. However, in order to get a better capture effect, you can set it first: select "Movie Snapshot Settings" in the "Capture Screen" drop-down menu, you can set the width of the captured dynamic picture in detail, the number of frames per capture, and the time of each frame Interval and playback speed of moving pictures. You only need to make a few adjustments. If you adjust too much, although the effect of the movie is better, the system's resource occupation and transmission speed must be slow.

Just select the corresponding function in the "Capture Screen" drop-down menu, and then play the movie normally. Press the ScrollLock key in a wonderful place, and the constantly refreshing movie screen will appear in the chat window. Just press "Send" to let Liaoyou also appreciated. It should be noted that this feature only supports movies played by Windows MediaPlayer, not movies played by RealOne. Of course, it also supports DV movie short films and supports RM and other formats, but you need to install a plug-in that supports RM format files for your WMP.

If you right-click on the received video and select "Save As", you can save it as a GIF image, and of course, save the animation effect.

Easy DOS screen capture

Screenshot

The above are screenshots under Windows, but what if you want to capture pictures in pure DOS? This is not complicated! Just use PIXELPOP software to achieve it.

Extract the downloaded file to a partition, such as under F: \ aa. Enter the pure DOS state, use the "CD" command to enter the folder, type "INSTALL" to install the software under "F: \ PIXELPOP". Enter the folder, enter "PP" to run the pp.dat file and start running. According to the screen prompts, the shortcut key for capturing screenshots is "Shift + PrintScreen". When the required screen appears, just press this shortcut key to enter GIF files starting with SCREEN are generated in the software installation directory. Each time a hot key is pressed, a GIF file is generated, and the serial number starts from 00, such as SCREEN00.GIF, SCREEN01.GIF, etc. (see Figure 7).

When this software is not needed, you can enter "PP / R" to uninstall from memory.

Virtual machine: grab everything

The previous screenshot methods under Windows and DOS, but there are still some screenshots that cannot be achieved, such as pictures of the BIOS setting interface, BIOS refresh interface, and Windows system installation process. Since these pictures do not run under the desktop operating system, they can only be performed with the help of virtual machine software.

Screenshot --- 3

There are two kinds of most common virtual machine software: Virtualpc and VMware. As long as the virtual machine software is used, the above-mentioned screenshots are easily solved: When the required screen appears, you can use the PrintScreen key to directly capture the picture! In addition In VMware, you can click the menu "File Capture Screen Image" command to save the special interface such as the startup screen, BIOS interface, and operating system installation interface.

There are no more questions about how to grab certain pictures and how to post-process them. "Teaching people to fish is worse than teaching people to fish". When you understand the basic methods of capturing pictures, I believe everyone can learn from each other and continue to explore more, better and faster methods of capturing pictures.
