Vector images, also known as object-oriented images or drawing images, are mathematically defined as a series of points connected by lines. The graphic elements in a vector file are called objects. Each object is an independent entity with properties such as color, shape, outline, size and screen position. Because each object is an independent entity, it can move and change its properties many times without affecting other objects in the legend, while maintaining its original clarity and curvature. These characteristics make vector-based programs especially suitable for legend and three-dimensional modeling, because they usually require the ability to create and manipulate a single object. Vector-based drawing is independent of resolution. This means that they can be displayed on the output device at the highest resolution.
The biggest difference between vector diagram and bitmap is that it is not affected by resolution. Therefore, when printing, you can enlarge or reduce the graphics at will without affecting the clarity of the drawing.
2. How to enlarge a small picture without changing the pixels? Ask experts for advice.
In the Start menu at the bottom of the computer-All Programs-Accessories-find the "Drawing" tool and enter the operation. The steps are shown in the following figure: (The computer comes with its own software, so it is convenient to use E68A84E8A2AA68696416F313336376432, without downloading and installing).
Send the photos you want to upload to your computer through your mobile phone or camera, and then modify them in turn. Generally, the photos uploaded in the exam registration are all photos with red background, and the size will be specified. You can follow his rules. For example, it is required that the pixel is 1 14* 156, the occupied space is less than 15kb, and the graphic format is.
First, you need to select Resize on the main menu, and a dialog box of Resize and Distortion will pop up. Then, you can select a pixel in this dialog box, uncheck the "Keep Aspect Ratio", enter the pixel you want in the dialog box (as shown in Figure 3 below), and then click OK.
The following figure is the frame diagram of pixel 1 14* 156, and the result diagram after completing the above steps.
Save the above picture first, and then enter the drawing tool. In the file in the toolbar in the upper left corner, select "Open", and the computer desktop file and the software of each disk will appear. Select the photo you want to use. After importing, you can modify the photos accordingly, or change the photo pixels, as shown in the figure.
When finished, select Save As from the File menu, set the file name, and then select the save type.
You can save it on the desktop. Right-click the selected attribute to see its size and pixels, and you can see its approximate size and detailed pixels, as shown below.
If the size is larger than the previously specified 15kb, the space occupied by the picture can be reduced without changing the pixels. We have built a drawing tool before. You can open the front one and then open the one with the picture at the same time.
Select the second finished picture and copy it.
In the first completed picture, select the whole large frame in the same way, paste the copied picture into it, and then save it as, and you will find that the original file becomes smaller.
Don't change the pixels, just change the file size, that's all. You need to read it carefully.
3. How to enlarge the photo in space to make the pixels unchanged?
Use a magnifying glass. You can't change the pixels of the photo or the pixels of the monitor; You can only change the way it is displayed.
You can zoom in and look at the photos in the space. It seems that the pixels of the original photos have not changed or the definition has not changed because the pixels of the original photos have been
Beyond the pixel setting of the display screen, what you see is actually a "reduced" display mode; But it's still very clear after zooming in, because you can't see the pixels in the original display mode.
The photos in the space are usually compressed and uploaded. Because, limited by space capacity and display mode. Either set the size or set the file size. If you upload at the size or pixel of the original photo, some can only see part, and some just need to be cut. So what we see as "the photo is enlarged to make the pixels unchanged" is actually false and untrue.
4. How to increase the picture size without changing the picture pixels?
solution
1, open the original picture first, and want to enlarge this picture, but the clarity of the picture remains the same.
2. Open this picture in ps software, as shown in the figure.
3. After directly enlarging the picture, you can see that the picture is distorted. Can't use it.
4. Change the picture back to its original pixel size, and then open Image-Image Size-Resolution. Enter the resolution value in the resolution input box, and you can see that the image size changes with the increase of the resolution value until the image becomes the desired size.
5. After clicking OK, the screen is very clear.
5. Seriously ask how to enlarge photos without changing pixels.
There are three concepts in enlarging photos:
First, enlarge the pixels of the image.
Digital photos belong to bitmaps, and the basic unit of bitmaps is pixels. Enlarging pixels is at the expense of image quality. After enlarging the pixel, the image will be blurred, so in general, it is not easy to enlarge the pixel.
Second, enlarge the resolution of the image.
Resolution refers to the pixels per inch per unit length. The higher the density, the higher the printing quality. However, enlarging image resolution is at the expense of image size. The higher the resolution, the smaller the print size.
Third, enlarge the image size.
Image size refers to the physical size of printed or printed images. The larger the size, the lower the resolution, so the larger the size, the more blurred the image.
Principle and method of enlarging image size;
According to the formula: pixel = resolution * size
It is not difficult to see that the resolution is inversely proportional to the size. The higher the resolution, the smaller the size, the lower the resolution and the larger the size.
6. How to enlarge a large picture without enlarging the pixels?
Sometimes we need to enlarge some pictures or photos, but this time the problem comes. After enlargement, it often becomes blurred or even mosaic. Is there any way to solve this problem?
Here is a small software to solve this problem. Let your picture enlarge without distortion.
PhotoZoom Pro is a novel tool for technological revolution, which is used to enlarge digital photos. When ordinary tools enlarge digital photos, the picture quality will always decrease. This software adopts S-spline technology (patented technology with automatic adjustment and advanced interpolation algorithm), which can improve the quality of enlarged pictures as much as possible. The biggest feature of this program is that it can enlarge pictures without aliasing and distortion.
By downloading software
The software is downloaded as a compressed file, and can be run without installation after decompression. Double-click the startup program to enter the main interface of the software. We can see that the main interface of the software is very simple and clear, so that users can see at a glance how to operate it, even if you are a novice, you can get started quickly. As shown in figure 1.
Figure 1
Click the icon on the top left of the software interface to open the photo to be processed in the pop-up window. Here we take an icon of "2008 Beijing Olympic Games" as an example. As shown in figure 2.
Figure 2
When the picture is imported into the software, we can see that the current pixel of the picture is 300*239. As shown in figure 3.
Figure 3
Next, we will enlarge the picture to 1200*956 pixels, and the picture will not be distorted. We enter a new size under the "new size" column, and then choose the way to change the size (choose S-Spline XL). As shown in figure 4.

Ok, the picture has been enlarged according to your preset multiple. Is the effect unbelievable? Let's export the picture, click the "File/Save As" menu and enter the file name in the pop-up window. The software provides five formats for saving, users can choose according to their own needs, and then click the "Save" button. Let's look at the enlarged picture. Personally, I think the effect is really great! As shown in fig. 5.
