Vector diagram, also called vector diagram, describes and records a graph with a series of computer instructions. A graph can be decomposed into a series of subgraphs composed of points, lines and faces. It records the geometric shape, line thickness and color of the object. The storage capacity of the generated vector diagram file is very small, and it is especially suitable for text design, pattern design, layout design, logo design, computer aided design (CAD), arts and crafts design, illustrations and so on.
Vector drawings can only represent figures composed of regular lines, such as engineering drawings, three-dimensional modeling or artistic words; For images (landscapes, figures, mountains and rivers) composed of irregular pixels, it is difficult to express them in mathematical form, so it is not suitable to use vector diagram format; Secondly, vector diagram is not easy to make colorful images, and the drawn images are not very real, which is not convenient for exchanging data between different softwares.
In addition, vector images cannot be obtained by scanning, and are mainly generated by design software. The vector drawing program defines (like mathematical calculation) the angle, arc, area and spatial direction relative to the paper, including the wireframe giving the filling and wheel features. Common vector graphics processing software includes CoreIDRAW, AutoCAD, Illustrator, FreeHand and so on.
Step 2 Bitmap
Bitmaps are also called bitmaps or pixel maps. The map on the computer screen is made up of luminous points (pixels) on the screen. Each point uses binary data to describe its color and brightness. These points are discrete, similar to a lattice. The tones of multiple pixels form an image, which is called a bitmap.
When the bitmap is enlarged to a certain extent, it will be found that it is composed of small squares, which are called pixel points, and a pixel is the smallest image element in the image. When dealing with bitmap images, pixels are edited instead of objects or shapes, and their size and quality depend on the number of pixels in the image. The more pixels per square inch, the clearer the image and the smoother the color mixture. Computer storage of bit images actually stores information such as the position and color data of each pixel of the image, so the clearer the image, the more pixels there are, and the greater the corresponding storage capacity.
Compared with vector images, bitmap images are more likely to imitate the real effect like photos. The main advantages of bitmap images are strong expressive force, delicacy, multi-level and many details, which can easily simulate the real effect like photos. Because the pixels in the image are edited, the clarity and smoothness of the image will be affected when the image is stretched, enlarged or reduced. Bitmap images can be obtained by digital camera, scanning or PhotoCD, and can also be generated by other design software.
Bitmap images, also known as dot matrix images or drawn images, are composed of individual points called pixels. When you enlarge the bitmap, you can see the picture elements that make up the image. Expanding the bitmap size means adding a single pixel, which will make the lines and shapes appear uneven. But if you go further,
From the position, the color and shape of bitmap images are continuous, which is the characteristic of bitmap. Vector images, also known as drawing images, are mathematically defined as a series of relationships between points. Vector image can be enlarged or reduced at will, and the image will not be distorted.
Question 2: The difference between bitmap and vector diagram.
Computers can display images in vector or bitmap format. Knowing the difference between them can help you improve your work efficiency. Fireworks allows you to create images with vector or bitmap tools in one software, or import and process vector and bitmap files generated by other applications. Fireworks provides bitmap editing mode and vector editing mode.
vectogram
Vector diagram is called vector because it uses line segments and curves to describe images. At the same time, the graph also contains color and position information. In the following example, the leaf describes the outline of the leaf by connecting a large number of points into curves. Then, according to the outline, fill some colors in the image.
When editing vector graphics, define the properties of lines and curves that describe the shape of the graphics, and these properties will be recorded. Operations on vector graphics, such as moving, redefining the size, redefining the shape or changing the color of vector graphics, will not change the display quality of vector graphics. You can also hide a part of a drawing or change the transparency of an object by overlapping vector objects. Vector graphics are independent in resolution. In other words, when you display or output an image, the image quality is not affected by the resolution of the device. In the example, the image on the right is an enlarged vector diagram, and we can see that the image quality is not affected.
bitmap
Bitmaps describe images with small points that we call pixels. Your computer screen is actually a grid with a lot of pixels. In the bitmap, the leaf image we see above will be determined by the position and color value of pixels in each grid. The color of each point is fixed. When we watch the image at a higher resolution, each point looks like a mosaic color block, as shown in the right picture in the following example.
When you edit a bitmap, you are actually defining the information of all the pixels in the image bit by bit, instead of just defining the contour lines and curves of the graphics like vector images. Because bitmap images of a certain size are recorded bit by bit with a certain resolution, the quality of these bitmap images is related to the resolution adopted when generating images. When the images are enlarged, they will appear at the edge of the image.
Their simplest difference is:
The loss diagram can be infinitely enlarged without distortion.
Bitmaps don't work.
So many friends' heads are distorted.
It doesn't look very comfortable ...
Hey hey. .....
What's more, bitmap is composed of pixels, while vector graph is composed of vector lines.
This is more professional.
Especially those friends who don't know what pixels are.
Ha ha.
Another difference is that bitmaps can display more colors.
However, there are relatively few loss graphs. ...
Therefore, the most basic thing is these differences.
Loss diagram is widely used in engineering drawing, such as ACD.
Bitmaps are more used in drawing, such as ps.
Therefore, we must master these basic knowledge to make further progress.
BMP didn't compress the picture.
JPG is compressed, but it is indistinguishable to the naked eye.

Question 4: What are the concepts of vector and bitmap in 4:PS? Bitmaps consist of pixels. Disadvantages: it's not clear if you zoom in too much. Advantages: convenient processing and wide application range.
Vector diagram is composed of mathematical functions, which will not affect the clarity after amplification. They are usually used in large drawing systems.
Question 5: What's the difference between bitmap and vector diagram? We should pay attention to the resolution when dealing with bitmaps. When processing bitmaps, the quality of the output image depends on the resolution set at the beginning of the processing. Resolution is a general term, which refers to the size of details and information contained in an image file, as well as the level of details that can be produced by input, output or display devices. When manipulating bitmaps, the resolution will affect the quality of the final output and the file size. Before dealing with bitmaps, you need to think twice, because the resolution chosen for the image is usually accompanied by the file in the whole process. Whether you print a bitmap file on a 300 dpi printer or a 2570dpi phototypesetting device, the file is always printed at the resolution set when the image is created, unless the resolution of the printer is lower than that of the image. If you want the final output to look the same as that displayed on the screen, you need to know the relationship between the resolution of the image and the resolution of different devices before you start working. Obviously, vector diagrams don't need to be considered so much. Vector diagram is also called object-oriented image or drawing image, and the traditional version is called vector diagram, which is 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. Vector diagrams are mostly geometric figures, which can be infinitely enlarged, not discolored or blurred. Commonly used in the design of patterns, signs, VI, words and so on. Commonly used softwares include Coreldraw, Illustrator, Freehand, XARA, etc.
Question 6: What is a vector diagram? What is a bitmap? What's the difference between them? Bitmaps are images composed of points (pixels). A point is a pixel, and each point has its own color. Bitmaps are directly related to resolution. The high-resolution bitmap has high definition and the magnification increases accordingly. However, when the magnification of bitmap exceeds its optimal resolution, mosaic and jagged edge will appear in the image!
Vector diagram records images in the form of mathematical vectors, and the contents are mainly lines and color blocks. The vector diagram has nothing to do with resolution, and can be enlarged at will under the same definition, and there will be no mosaic and jagged edge!
Question 7: What is a vector diagram? Bitmap? Vector diagram? What is the difference? Vector diagram is a vector diagram calculated by formula, no matter how enlarged, it will not affect the clarity.
Representative software artificial intelligence
Vector images can be converted into bitmaps by ps.
Bitmaps consist of points. If you put them big enough, they will become blurred.
Representative software PS
Question 8: What does vector diagram mean? Graphics displayed in a computer can generally be divided into two categories: bitmap and vector.
The photos taken at ordinary times are bitmaps, which are composed of pixels and then enlarged into mosaics.
Vector graphics can only be generated by software, that is, images created by designers, whose element objects can be edited. Enlarging or reducing the image will not affect the resolution of the image, that is, mosaic or sawtooth will not appear no matter how enlarged. Because it is originally a graphic created by people with software.
Question 9: What's the difference between graphics, images, vector diagrams and bitmaps? (1) Image corresponds to "Image" in English. It is similar to a photograph. Because there are many points arranged in rows and columns, when each point is small enough, a photo looks very clear from a macro perspective.
(2) Graphics corresponds to "graphics" in English and is more similar to logical concepts, such as triangles, circles or curves. They are all called graphics, not images.
Why are these two words sometimes mixed? Because graphics exist in logic, it must exist in some display medium, such as a display or printed on paper, and once the graphics are "displayed" on the display, they become images.
So you should know that graphics and images are different.
Step 2 solve
The resolution here refers to how many pixels an image contains in the horizontal and vertical directions. For example, the resolution of a digital camera is 3 million pixels. 3 million pixels means that the photo it takes contains 3 million points. Of course, the 3 million here is an approximation. To be precise, there are 2048 pixels in the horizontal direction and 1536 pixels in the vertical direction. The rectangular area formed by them includes 2048 x 1536 = 3 1536.
3. Bitmap pixels
With the above foundation, we can understand the following two concepts more deeply, namely bitmap image and vector graphics. Pixel grid. In bitmap, the image is determined by the position and color value of each pixel in the grid. Each point is given a color, and these points are put together like stickers in a mosaic to form an image.
The advantage of bitmap image is that it can ensure the details of the image, so the photo is a typical position image. One of the characteristics of bitmap is that it will become blurred after enlargement.
When editing bitmap graphics, pixels are modified, not lines and curves. Bitmap graphics are related to resolution, which means that the data describing the image is fixed in a grid of a specific size. As mentioned earlier, enlarging a bitmap image will redistribute these pixels in the grid, which usually makes the edges of the image jagged. Displaying a bitmap image on an output device with a resolution lower than the image itself will also reduce the image quality.
4. Vector graphics
Suitable graphics use lines and curves called "vectors" (containing color and position information) to present images. It uses a series of curves to describe the circular outline and stroke outline of Chinese characters. The color of a figure is determined by the color of its outline and the color of the area around the outline.
When editing a vector diagram, you can modify the properties of lines and curves that describe its shape. Vector graphics have nothing to do with resolution, which means that in addition to being displayed on output devices with different resolutions, you can also perform operations such as moving, resizing, changing shapes or colors without changing its appearance quality.
The disadvantage of vector graphics is that it can't express details, for example, every point in a photo can't form a curve that can be described by mathematical equations.
