Vector graphics use mathematical vectors to draw graphics
Therefore, the size of the drawn image will not affect the file size (because the mathematical vectors are similar)
Therefore, the image can be freely enlarged and reduced
without aliasing
What affects the size of the vector image file
is usually the complexity of the objects in the image
The more objects there are, the more complex the graphics will be.
This will cause the vector file to become larger.
In engineering drawings
or when making geometry diagrams. When it comes to large or simple graphics
Vector graphics are a better choice

Visio

To define 2006-11-05 13:50:01 Supplement: Vector drawing software such as Adobe Illustrator produces vector images, which are composed of straight lines and curves defined by mathematical objects called "vectors". Vectors describe graphics according to their geometric properties. For example, a bicycle tire in a vector image consists of a mathematically defined circle that uses a specified radius, is positioned at a specific location, and is filled with a specified color. You can move the tire, change its size, or change its color without affecting image quality. A vector image is resolution independent; in other words, it can be scaled to any size and printed to any output device at any resolution without losing its detail or clarity. Therefore, vector images are the best choice for text (especially small fonts), or images that must have clear and distinct lines regardless of scaling (such as trademarks).
Maybe I didn’t answer in detail... But I can tell you that there are two main types of floor plans in computers. The first one is bitmap. Many times I see a D PIXEL doll or a person. CG are all bitmap images. If you zoom in, you will see that they are actually composed of dots
And the number of dots (delicacy) is also determined by DPI. Many times when you take a D image out, the PAINTOUT will have the same DPI. Most of the images and photos that affect the quality of the results are imported using bitmap graphics! Vector graphics are different from bitmap graphics. They are the first graphics that appeared in modern times. Vector graphics use numerical values ??to accurately calculate the size of a pattern. If you have used ILLUSTRATOR, you know that AI drawings are not like drawing with PHOTOSHOP. Because AI drawings are drawn with numbers, they can make relatively simple lines, so it is very complicated to do it... just like an airbrush. The effect of vector graphics such as watercolor and watercolor may not be achieved, but it is very easy to use when making LOGO or fonts. Although many computers are used to calculate bitmaps, bitmaps are not calculated by the computer, only dots are calculated. *** Make a picture
Just like a photo put into the computer, the vector diagram is calculated in the form of calculation. You can try using ILLUSTRATOR to draw the picture below.
Reference: Experience
Vector images represent images using line segments and curves (called vectors) that contain color and position information. When editing a vector image, you can modify the properties of the line segments and curves that describe the shape of the image. Vector images are resolution-independent, which means you can move, resize, modify the shape, or change the color of the vector image. You can also display the vector image on output devices with different resolutions without changing its appearance quality. . Bitmap images are made up of dots (called pixels) arranged in a grid. When editing bitmap images, you modify pixels, not line segments and curves. Bitmap images are resolution-dependent, that is, the data describing the image are fixed to grid lines of a specified size. Magnifying a bitmap redisperses the pixels in the grid, often resulting in jagged image edges.

Bitmap uses pixels (or points) to depict an image
How big is the layout?
The computer will store as many points as possible
In addition
The more colors the bitmap has, such as 16bits or 32bits
It is larger than black and white or 256-color bitmaps
Because more space is used when drawing each point
So if When archiving
Just measure the amount of color you use
Lower the archiving color
The advantage of bitmap is that it can present complex photos and gradients Effect
There are many such file formats
such as jpeg
bmp
tif
psd, etc.< /p>
Common tools such as photoshop
paint
Little painters, etc... Bitmap: a graphic composed of squares of pixels (Pixels) If the file is enlarged, each pixel grid will appear jagged. If the file is reduced, some image points must be cleared to fit the smaller graphic size. Photoshop and other drawing and image editing programs have fixed resolutions. , can produce bitmap images (also called "bitmap images"). Bitmap images use a grid of small squares called "pixels" to represent images. Each pixel is assigned a specific position and color value. For example, a bicycle tire in a bitmap image is composed of a bunch of pixels collaged at this location. When working with bitmaps, you edit pixels, not objects or shapes. Bitmap images are related to resolution, in other words, they represent their image data with a fixed number of pixels. Therefore, if viewed at high magnification on a screen or printed at a resolution that is too small, bitmap images may lose detail and become aliased. Bitmap images are the best choice for expressing fine gradations of intensity and color, such as in photographs or bitmap images. Vector graphics: a group of graphics that can be easily changed in size and quality. Lines and curves will not be deformed. The effect is excellent. Vector graphics software such as Adobe Illustrator uses mathematical methods to define vector images, so it is called "Vector" is a mathematical object defined by straight lines and curves. Vectors describe graphics according to their geometric properties. For example, a bicycle tire in a vector image consists of a mathematically defined circle that uses a specified radius, is positioned at a specific location, and is filled with a specified color. You can move the tire, change its size, or change its color without affecting image quality.

Therefore, vector images are the best choice for text (especially small fonts), or images that must have clear and distinct lines regardless of scaling (such as trademarks). Since computer screens display images in a grid format, vector and bitmap images are displayed in pixel format on the screen.
