What is a "vector"
Vector diagram is the use of mathematical vectors to draw patterns.

So the size of the drawn graph will not affect the size of the file (because the mathematical vectors are almost the same).

So the picture can be enlarged and reduced freely.

No serrations.

Affect the file size of vector diagram.

Usually it is the complexity of the objects in the picture.

The more objects, the more complex the pattern.

Will cause the vector graph file to become larger.

In engineering drawing

Or when making several combined patterns or simpler patterns.

Vector diagrams are all good choices.

The commonly used tool software is Coreldraw.

Vector drawing software

Illustrator

AutoCAD et al. 2006-11-0513: 49: 50 Supplement: Vector drawing: The size and quality can be easily changed by one group, and the lines and curves will not be deformed, with excellent effect. In order to mathematically define 2006-11-0513: 50: 01,vector drawing software such as Adobe Illustrator produces vector images, which are composed of lines and curves defined by mathematical objects called "vectors". Vectors describe graphics according to the geometric characteristics of images. For example, a bicycle tire in a vector image consists of a mathematically defined circle, which uses a specified radius, is located at a specific position, and is filled with a specified color. You can move the tire, change the tire size or change the tire color without affecting the image quality. A vector image has nothing to do with resolution, in other words, it can be scaled to any size and printed to any output device at any resolution without losing its details or clarity. Therefore, for words (especially fine print) or images with clear lines (such as trademarks), vector images are the best choice regardless of the scale.

Maybe I didn't answer in detail .. but if you can, you know there are two main plans in the computer. The first one is a bitmap. Sometimes you will see a D-pixel doll or personal CG. When I enlarge the bitmap, I will see that it is actually made up of a little bit.

And the number of standing points (fineness) is also determined by DPI. Many times, D-drawing is related to DPI, which affects the effect. Most images and photos are imported from bitmap frames! A vector diagram is different from a bitmap. Compared with the modern bitmap, the existing vector diagram accurately calculates the size of a pattern by numerical value. If you have used ILLUSTRATOR, it is well known that the existing drawings of AI are not very similar to those drawn by PHOTOSHOP. Because AI's existing drawings are composed of numbers and can make simple lines, it is very complicated to do ... Watercolor, like airbrush, doesn't have to be done with effect vector drawings, but it is very easy to use for LOGO or fonts. Although many fields are calculated by computer, they are not bitmaps, but just pictures of dots.

This is like putting a photo into a computer and calculating a vector diagram in the form of calculation. I wonder if I can try to draw the following picture with ILLUSTRATOR.

Reference: experience

Vector images use line segments and curves (called vectors) containing color and position information to present images. When editing a vector image, you can modify the attributes of line segments and curves that describe the shape of the image. Vector images are independent of resolution, that is, you can move, resize, modify shapes or change the color of vector images. You can also use output devices with different resolutions to display vector images without changing their appearance quality. A dot matrix image consists of dots (called pixels) arranged in a grid. When editing a dot matrix image, pixels are modified, not line segments and curves. The raster image is related to the resolution, that is, the data describing the image is fixed on a grid with a specified size. Enlarging the dot matrix graphics will redistribute the pixels in the grid, which usually leads to jagged edges of the image.

Bitmaps use pixels (or points) to describe images.

How big is the layout?

How many points will the computer save?

besides

The more colors a bitmap has.

For example, bit 16 or bit 32.

Larger than black-and-white or 256-color bitmap

Because when describing each point,

The more space you need.

So if at the time of application,

It just depends on how many colors you use.

Reduce the color of archived files.

The advantage of bitmap is that it can present complex photos and gradient effects.

There are many such file formats.

Such as jpeg

Extension of bitmap file

Label image file format.

Little painter, etc ... bitmap: a graphic file composed of pixel squares. If you zoom in, each pixel box will appear jagged. If you zoom out, you must delete some points to meet the smaller graphic size. Photoshop and other drawing and image editing programs with fixed resolution can generate raster images (also called raster images). A dot matrix image uses a small box called a pixel to present an image. Each pixel is assigned a specific position and color value. For example, a bicycle tire in a point array image is composed of a bunch of pixels collaged at this position. When processing raster images, you edit pixels, not objects or shapes. A raster image is related to resolution, in other words, it represents its image data with a fixed number of pixels. Therefore, if you enlarge at a high magnification or print at a too small resolution on the screen, the details of the dot matrix image may be lost and jagged. Dot-matrix images are the best choice for displaying subtle gradients in density and color (such as photos or dot-matrix drawing images). Vector drawing: It is composed of a set of vector drawing software such as Adobe Illustrator, which can easily change the size and quality, and the straight lines and curves will not be deformed, and the effect is excellent. In order to define vector drawing software mathematically and generate vector images, these images are composed of straight lines and curves defined by mathematical objects called "vectors". Vectors describe graphics according to the geometric characteristics of images. For example, a bicycle tire in a vector image consists of a mathematically defined circle, which uses a specified radius, is located at a specific position, and is filled with a specified color. You can move the tire, change the tire size or change the tire color without affecting the image quality. A vector image has nothing to do with resolution, in other words, it can be scaled to any size and printed to any output device at any resolution without losing its details or clarity. Therefore, for words (especially fine print) or images with clear lines (such as trademarks), vector images are the best choice regardless of the scale. Because the computer screen displays images in grid mode, both vector and dot matrix images are displayed on the screen in pixel mode.
