Task
Prepare for the lesson. Check which operating systemoperating systemoperating system is installed on your home computer and on your school computer.

Think for what purpose do you capture the imageimageimage from the monitor. Are the captured images of good quality? What does this quality depend on?

Proceduremff636156f6f63382_1528446435040_0Procedure

While you are working on the computer, you may need to save the image which is displayed on the monitor (as a single photo or video) in the memory of your computer. It is not as difficult as it seems, although in different operating systems (Windows, Linux, MacOS and others) you can do this in different ways. Due to the common use of the MS Windows system, we will focus on capturing the image in this operating system family.mff636156f6f63382_1527752263647_0While you are working on the computer, you may need to save the image which is displayed on the monitor (as a single photo or video) in the memory of your computer. It is not as difficult as it seems, although in different operating systems (Windows, Linux, MacOS and others) you can do this in different ways. Due to the common use of the MS Windows system, we will focus on capturing the image in this operating system family.

The basic type of images that we may want to capture are static images, i.e. single „photos”. The mechanism of capturingcapturingcapturing static images (also called „screenshots”) is provided by the operating systemoperating systemoperating system itself, and the „Print Screen” key is used for that purpose. On some keyboards the description can be found in a short form of „PrtScr”. All you need to do is to press this key shortly and the system will save the imageimageimage of the entire screen (workspace) to the clipboard from which you can paste it into a graphic program or a text editor. Pressing the key and saving the imageimageimage will not be signaled by any sound or any other form of message. Having a captured image in the clipboard it is sufficient to paste it into the graphic program by using the appropriate function (this function often appears under the keyboard shortcutkeyboard shortcutkeyboard shortcut „Ctrl + V”). The saved imageimageimage does not contain the mouse cursor, so we do not have to worry that the cursor will overshadow, for example, a fragment of the picture. We must remember that such picture will have the resolutionresolutionresolution identical with that displayed on our monitor. Thus, if we are going to display, for example, a photo or a map hoping to get a picture of high resolutionresolutionresolution, the quality of the picture will be exactly of the quality that our monitor provides.

If we want to capture only a fragment of the entire work screen, after pasting the screenshot into the graphic program which we use, we need to cut out this fragment we are interested in. If the current work window is the part we are interested in, then we can simplify the procedure by using the „Alt + Prtint Screen” shortcut, which will capture only the current window instead of the whole work area.mff636156f6f63382_1527752256679_0If we want to capture only a fragment of the entire work screen, after pasting the screenshot into the graphic program which we use, we need to cut out this fragment we are interested in. If the current work window is the part we are interested in, then we can simplify the procedure by using the „Alt + Prtint Screen” shortcut, which will capture only the current window instead of the whole work area.

In the case of screenshots of websites, the most common problem is that the page is long and cannot fit the screen, so the screenshotscreenshotscreenshot will not cover the whole page. Producers of some browsers have noticed this problem and they have developed add‑ons that enable the user to capture whole pages, including very long ones. In the Chrome browser, you can install the „Full Page Screen Capture” add‑on which, by the „Alt + Shift + P” shortcut captures the whole page screenshot and displays it in the newly opened browser tab. We can save such a picture on the disk or copy it to the clipboard. However, this plugin will not work on pages with proprietary content. If you use Firefox, you can use the „FireShot” add‑on (you can also find it under the name „Full Web Page Screenshots”). In this case, you can use the shortcut „Shift + Ctrl + Y” to copy the window. Regardless of the browser add‑ons, you can use „Site Shoter” application. You can find it at nirsoft.net. This softwaresoftwaresoftware enables capturingcapturingcapturing a screenshotscreenshotscreenshot of any website (or page list) by saving its imageimageimage to disk. Unlike the above mentioned add‑ons, in this program it is possible to specify many parameters in the configuration, including the imageimageimage format and the degree of compression, as well as to use a differentdifferentdifferent browser window resolutionresolutionresolution than the one we actually use.

In other systems we capture images in the same way but using different keyboard shortcuts. In Linux we press PrtSc or PrtSc + Ctrl to save the whole screen image or Alt + PrtSc to save the image of the active window. In the Mac OS operating system the Shift + cmd + 3 shortcut is used to save the entire screen image or the Shift + cmd + 4 shortcut is used to keep the image of the active window.mff636156f6f63382_1527712094602_0In other systems we capture images in the same way but using different keyboard shortcuts.

To capture the imageimageimage from the monitor, appropriate keyboard shortcuts should be used. For Windows the PrtSc button should be used to save the entire screen image or Alt + PrtSc to save the imageimageimage of the active windowactive windowactive window. In the Linux system, the screenshotscreenshotscreenshot is captured in the same way. DifferentdifferentDifferent abbreviations are used in the Mac OS operating systemoperating systemoperating system.

After capturingcapturingcapturing the image, it should be pasted into any raster graphics editor and saved in the memory of the computer.
