Empty Gloves White Wolf: Windows Image Capture Guide

After Lingling bought the computer, she learned very hard and mastered some basic knowledge and operation skills. Many students called to ask her! However, many of the questions are unclear, and the phone does not understand for a long time. If you can look at the picture to compare, it will be much better.

Lingling once again found a free man brother. After listening to her thoughts, the free man replied: "It's very simple, just take a screenshot of the current screen. However, when you save the file, you need to have a certain understanding of the image format, I will give you a comprehensive talk."

a screen shot with the image format knowledge

1. Screen capture operation guide

"To cut out the current computer screen, the most common method is to press the Printscreen button on the keyboard (Figure 1). Then open any image processing software, create a new file, in the menu Or select "Paste" in the right-click option, the screen will come out (note that if the image processing software, do not open the Notepad program to paste it).

Figure 1
"Common image processing software comes with Windows The drawing program also has the famous PhotoShop and so on. The drawing program can be used by clicking “Start → Programs → Accessories → Drawing” (Fig. 2), creating a new file, then selecting “Paste” in the editing area, or holding down the Ctrl key, then pressing the V key (Fig. 3).

"Note that, this is a full screen Printscreen are taken down, and sometimes there will pop up a program For several levels of menus, if you only need a screen of a certain dialog box, you can activate the screen first (make it in front and be selected), then hold down the Alt key, then press Printscreen to "paste" into the drawing program. "Yes."

"Free man brother, why do I want to use the Printscreen button you introduced to take a screenshot when I watch a movie, but I found it to be black?"

"That's because Windows uses Direct X drawing mode for dynamic video files. It is different from static images. In general, unless the playback software itself supports screenshots, you need to use a special screenshot software such as HyperSnap (download address) :http://dl.pconline.com.cn/html/1/1/dlid=581&dltypeid=1&pn=0&.html
) to complete the operation (for details, please refer to Help documentation for such software).

"If installed on your computer More than one kind of playback software, there is another method - first open a player, play any file, pause, do not close, then open another player, play the video file you want to capture, you can use the Printscreen button or The Alt+Printscreen key is taken directly. Paste and other operations are the same as described above. "

"Why do you have such a special operation?" "

"Because the first playback software called the Direct X drawing function, it was not closed, and the second playback software was opened again. Windows cannot use the Direct X method." At this point, the image can be captured in the usual way.

2. Basic knowledge of image format

After the screen is intercepted, we have to save the file. Only save the file to the netizen. For example, in PhotoShop, We can see that there are a variety of save formats (Figure 4). Of course, the most common one is to save the format of the extension JPG, which is called Joint Photograhic Experts Group, which uses a distortion method to compress and compress the image. The ratio is usually between 10:1 and 40:1. Such images take up less space and are suitable for network transmission.

Others Common formats are:

TIFF format: The extension is TIF, the full name is Tagged Image File Format. It is a non-distorting compression format that preserves the color and level of the original image, but takes up The space is very large. A 2 megapixel image takes up almost 6 MB of storage capacity, so TIFF is often used for more professional purposes, such as book publishing, posters, etc., and is less used on the Internet.

BMP format: English Bitmap (bit Shorthand for illustration. It is the standard image file format in Windows, which is widely used with the popularity of Windows. The default storage format of the "drawing" program that comes with Windows is this. It contains more complete image information, but The disk space occupied is also quite large.

There are many other image formats, such as FPX, RAW, TGA, etc., which are used in printing, photography, etc., and there are not many opportunities in daily life. It doesn't mean much for beginners, so I won't list them one by one.

"Oh, this way! We should choose JPG format to save, right? "

"Yes, usually select JPG, and other formats of images, you can also use the above saved operation to become JPG format to reduce the size. When saving JPG, PhotoShop professional software usually has image quality grades for you to choose (Figure 5). If you just want to send a schematic to the other party and do not pursue precise results, usually choose 3 to 5 files. Yes; if you want to maintain the original picture, you must choose 7 to 10 files to ensure the image is clear. The lower the grade, the smaller the volume, the smaller the hard disk space occupied, and the faster the network transmission.

"Then I also saw some small icons on the Internet. What kind of format is this?"

" This is called the GIF image format. It combines several to dozens of images into one file, and when it is opened, it plays like a slideshow, achieving dynamic effects. During the compression process, the pixel data of the image is not lost. However, the color will be lost. The GIF format can only store up to 256 colors, so it is usually used to display simple graphics and fonts. Generally speaking, do not use PhotoShop, drawing and other programs to edit GIF files, or it will become static graphics after saving. To maintain a dynamic effect, you should use a special GIF editing software, such as Advanced GIF Animator (download address: http://dl.pconline.com.cn/html/1/8/dlid=10558&dltypeid= 1&pn=0&.html
), etc. for processing.”

Second, about wallpaper and commonly used viewing software

1. Set wallpaper learned

"free man his brother, a classmate asked me, after she set wallpaper, windows 98 startup time, how not to see the photograph of the new wallpaper set, but appeared old Wallpaper, and then refreshed into a new one?"

"This is because your classmates use JPG format wallpaper, while Windows 98 desktop uses Web mode, Windows 98 supports Web mode is not perfect So this happens. Just convert the JPG format to BMP and load it directly. In Windows 2000 and XP, this situation has been improved and there is no need to specifically convert the format."

2. Browse software recommendation and batch conversion format

"Oh, it seems that the learning in the image format is really a lot! Then, I have collected a lot of pictures, what is better to browse and manage?"

"I recommend using ACDSee this software (download address: http://dl.pconline.com.cn/html/1/1/dlid=1&dltypeid=1&pn=0&.html
), it can not only view pictures in full screen, play slides, etc., but also convert image formats in batches, select the files you want to convert, click on the tool options, click on "Convert Image Format" (Figure 6), A pop-up menu will let you choose the format to be generated. After you select it, you can start the conversion (Figure 7). There are many other useful functions that are easy to use and you can learn by yourself." br>
