Resizing photos is easy. It is only important to choose your own, in which it is most convenient to work. The most affordable option for resizing images is to use a standard office tool. Microsoft application Office Picture Manager. To do this, open the folder with the desired photo, hover over it, click right click mouse and in the drop-down window select the “Open with...” option and check the pop-up panel on the right Microsoft Office Picture Manager. When your picture opens in the application, find and click the “Edit Pictures” button on the top toolbar. After that, in the window that opens on the right, select “Resize”. Then give the image required parameters. For convenience, you can use ready-made options. Select “Standard width and height” and specify the desired photo size. Or set a custom width and height.

To resize a photo, you can use another program that is available on every computer with the Windows operating system installed - Paint. Open the image using Paint, select the “Drawing” menu on the toolbar, and then select the “Attributes” option in the drop-down window. After which a new window will appear on the program desktop, in which the image dimensions will be indicated. Here you can set your parameters. In this case, do not forget to select the appropriate unit of measurement: inches, cm, points. Or simply drag the boundary change handles. Then save the result. Please note that this will change not only the image size, but also the photo itself: after all, you will crop parts of it.

If you have Photoshop installed on your computer, open the image you need to process using this program. Then, on the toolbar, click the Image button and select Resize Image. Set the required width and height, check the box next to “Maintain proportions” and save the finished result using the “Save As” functions in the “File” menu.

If you take a photo in high resolution, the resulting graphics can be printed in large format. Maximum size photography will depend on the capabilities of your camera.

Instructions

The size of a photo is determined in pixels and depends on the number of millions of pixels (megapixels) of your . So, a 2 megapixel camera can nice shot in a maximum resolution of 1600x1200 pixels, and without loss of quality, such a photograph can be printed on 10x15 cm photographic paper. A photograph of a 24 megapixel camera will have 5398x3602; it can be in ideal quality on photographic paper measuring 45x30 cm - this is a little more than A3, or two sheets of A4 format.
So, the more megapixels your camera has, the more opportunities you have to take a larger photo and then print it.

Useful advice

Please be aware that the pictures high resolution take up more space on the camera's memory card.

In most cases, the file is compressed information. It is compressed according to the format in order to reduce A object, this often leads to a loss of quality. In case of small size, it is convenient to use such files because they are downloaded and processed faster. But this also has a downside - some file hosting services may not accept our file because it is too small size, in this case it is necessary to increase the size.

Instructions

If you need a size, you can increase its area through the editor. Specific also increases size file. If we do not want to change the area of ​​the image, but want to change only the size itself, then we can save without compression by using formats that do not have compression, such as those with the ".bmp" extension.

In order to change the size of an audio track, it must be done through the editor. Once you open it, save it by setting the settings to a higher bitrate than what is in present moment. Quality file will not change, but due to the program settings, the size of the audio track will change. You can also save a track using the ".wav" extension, which is not a compression format, like the ".raw" format, respectively, due to this its size is also .

If you need to increase the size file, you must open it through a special editor, and then save it with higher quality settings and less compression. You can also change the one in which you save the file to the one that supports the lowest compression ratio.

If you find that your PC is using up all the virtual memory, you will have a reasonable desire to increase its size. Virtual memory in the environment operating system Windows is located in the page file (pagefile.sys). There are several ways to increase the volume of virtual memory.

Instructions

So, if you are using Windows XP, open Control Panel, then go to the System window and select the Advanced tab. Next you will see the “Performance” section. Click the “Options” button in it and in the “Performance Options” window, activate the “Advanced” tab. The total file size (volume available at a given time) on all disks will be indicated in the section called “Virtual”. Click on the “Edit” button to proceed to editing the paging file settings.

The initial size of the paging file in the system is 2048 MB. It can be expanded twice. There are three options for setting the volume of virtual memory:- The size of the paging file at the choice of the system allows the OS to manage the size of the virtual memory;- Special size allows you to enter the maximum size of the paging file. It is better to set both of these values ​​based on the physical operational memory(1.5 and 2 times more). That is, with an RAM volume of 2 GB, the initial size of the paging file should be set to 3072 MB, and the maximum - 4096 MB; - The third option is distinguished by the absence of a paging file. Use it if you have a large amount of RAM and you know for sure that you will not need memory.

In Vista OS, the amount of virtual memory can be increased in a similar way. But there is more convenient option– use ReadyBoost technology. Just connect the flash memory to the USB connector of your PC. A window will pop up indicating that a removable storage device has been connected to the system. Now you just need to select the “System acceleration” option. In the ReadyBoost settings page that opens, select “Use this”. Now use the slider to select the desired volume memory.

To understand the processes that occur in the system and are associated with its performance, you need to know the meaning of two concepts - virtual memory and the paging file. A page file is a file in disk space (as opposed to RAM, which is a separate device) that the system uses to store data that does not fit in RAM. Virtual memory is RAM together with the page file. Checking it involves a number of simple measures.

Instructions

Diagnose the state of virtual memory. Typically, the system independently sets the optimal amounts of virtual memory, and it is enough to solve most tasks, but in the case of running applications that require large amounts of RAM, the amount of virtual memory can and should be increased. If such a need arises, the system will display a warning about insufficient virtual memory.

By clicking on the “My Computer” icon, open the context menu and select “Properties”. In it, go to the “Advanced” tab, where in the “Performance” section, click on the “Options” button. In the window that opens, click on the “Advanced” tab, and in the “Virtual Memory” section, select “Change”.

Click the “Custom Size” option in the “Swap File Size” list in the window that opens. In the "Original" and "Minimum" text boxes, select a range of paging file sizes from its minimum to its maximum. The minimum size should not be less than one and a half times the size of RAM. The new virtual memory size will be set.

In addition, it may be necessary to completely clear the virtual memory - this procedure is useful if the user works with valuable and confidential data, since their remains are often stored in the virtual memory.

Type “secpol.msc” in the Start menu search bar. This action will launch the Local Security Policy utility.

Go to the “Security Settings” submenu of the “ Local policies» section "Security Settings". In the list of options on the right side of the window, find the line “Shut down: clear the paging file” and click on it. In the window that opens, set the switch on the “Local Security Option” tab to the “Enabled” position. Now, every time you shut down, the contents of virtual memory will be destroyed.

The operating system needs a paging file when there is no longer enough RAM. Very often, when playing a new video game, you can find yourself in a situation where a notification appears that the game does not have enough memory and you need to increase the page file. Also, if for some reason you run several large programs at the same time, you may notice that your computer begins to work much slower. To normalize PC operation, you need to set the paging file to a larger size.

You will need

• - a computer with Windows OS (XP, Windows 7).

Instructions

To set the paging file size yourself, follow these steps. Owners of computers with the Windows XP operating system need to act this way. Right-click on “My Computer”. From the context menu, select Properties. After that, go to the “Advanced” tab. In it, find the “Performance” section and click the “Options” button. Now select "Advanced" again. Next, find the “Virtual Memory” section and select “Change”.

A window will appear in which you can manually set the size of the paging file. In this window, find the line “Special size” and mark it with the left mouse button. You can now assign the page file size. There are two lines available to you: “Original size” and “Maximum size”. The same value must be entered in these lines. If the RAM size is two gigabytes, then it is recommended to set the value to 4096 megabytes, but if the memory size is two or more gigabytes, then 2048 should be enough. After this parameter has been specified, click “Set” and OK at the bottom of the window. Close all windows by clicking OK one at a time.

In the case of the Windows 7 operating system, it is only in its final stages. When you open the “Virtual Memory” window, you will need to uncheck the box next to “Automatically select paging file size”. After this, check the “Specify size” checkbox and write the same value in two lines. Click OK. The window will close. Thus close all other windows. Also at the bottom of the “Virtual Memory” window, you can see the system’s recommendations on the amount of paging file that should be installed.

Useful advice

Please note that memory for the paging file is reserved on the system disk by default. Therefore, make sure that there is enough free memory on it.

Typically in files obtained using digital cameras or scanners have a very large pixel size. Images transmitted via the Internet, including photos, are pre-reduced to save traffic, so the need to increase their size arises quite often.

The main problem associated with increasing size raster images, is that the graphic editor has nowhere to get information about the color of the pixels that are added to the picture to enlarge it. The program copies existing pixels and as a result, the enlarged image is much inferior in quality to the original image. If it is impossible to avoid increasing the linear dimensions of the file, the image must be adjusted after the transformation is completed.

You will need

• - Photoshop program.

Instructions

Most known method increasing the size of a picture using regular Photoshop tools consists of successively changing the size by ten percent using the Image Size option from the Image menu. To use this method, open the size settings window and change the pixels in the Pixel Dimentions panel. In any of the fields in this panel, enter the value 110%. Select Bicubic as the interpolation method and click OK.

If you need to enlarge the picture by ten to twenty percent, the image quality will not suffer much. However, view the edited image by zooming in to one hundred percent in the Navigator panel. It may turn out that the color noise present in the original image has become more noticeable along with the picture. Remove noise using the Reduce Noise filter from the Noise group of the Filter menu.

If compression artifacts become noticeable in certain areas of the image, if possible, remove them using the Clone Tool. To do this, place the cursor on a fragment of the image that is colored the same color as the area being edited, but does not contain artifacts. Hold down the Alt key and click on this area with the mouse. Click on the editable portion of the image. Pixels from the area that was selected as the cloning source will be copied onto it.

Duplicate the layer using the Duplicate Layer option from the Layer menu. Sharpen the duplicate layer by first converting it to color mode Lab using the Lab option from the Mode group of the Image menu. In the dialog box that appears, click the Don't Merge button to save the layers.

In the Channels tab, click on the Lightness channel and apply the Unsharp Mask filter to it. To see the result of applying a filter to a color image, click on the Lab channel.

Change the picture back to RGB mode. Adjust the opacity of the filter layer to achieve the optimal combination of sharp and blurry images.

Save the enlarged image to a jpg file using the Save As option in the File menu.

The “System Properties” window will appear on the screen, in which go to the “Advanced” tab and click the “Options” button in the “Performance” section. In the window that opens, go to the “Advanced” tab and click the “Change” button.

The “Virtual Memory” window will appear on the screen. This window allows you to set file parameters that are more optimal for your work. swap than the default settings that the operating system uses.

File swap located on a hard computer disk, the reading speed of which decreases from its beginning to its end. Therefore, to get maximum file speed swap, place it, if possible, on the very first partition of the hard drive. To do this, select all other sections from the list located in the upper half of the window, check the “Without file” checkbox for them swap" and click the "Set" button.

You can also change the file size swap, making it more optimal. By default, the Windows operating system itself chooses the file size swap. First, it sets its size to the smallest possible size in order to save as much free space on the hard drive as possible. As soon as the size specified by the operating system becomes small, it automatically increases it. At this point, the computer may freeze for several seconds. If the size increases often enough, working with the computer becomes uncomfortable.

You can disable automatic file resizing swap, immediately setting for him suitable size. To do this, select in the list the partition on which the file is located swap and check the “Specify size” checkbox. Specify the minimum file size in megabytes swap, which will not require its frequent increase while working in the “Original size” field.
