Bitmap: A bitmap image uses points of different colors in each grid to describe image attributes. These points are what we often call pixels. Bitmap images are not resolution independent because the data describing the image is for the image in a raster of a specific size. Therefore, editing a bitmap will change its display quality, especially scaling the image, because the image is in the raster. The redistribution within the grid results in rough image edges. Displaying the image on an output device that has a lower resolution than the bitmap image itself also reduces the display quality of the image.
Bitmaps are also called bitmaps, which are composed of many dots. These dots are called pixels and can produce colorful pictures, but they will be distorted when enlarged and require a large space. In contrast, Vector graphics. There will be no distortion when enlarging, but you cannot create colorful pictures. They take up less space.
Vector graphics: Graphics displayed on computers can generally be divided into two categories - vector graphics and bitmap graphics. picture. Vector graphics use straight lines and curves to describe graphics. The elements of these graphics are points, lines, rectangles, polygons, circles, arcs, etc., which are calculated through mathematical formulas. For example, a vector graphic of a flower is actually an outline of an outer frame formed by line segments. The color of the outer frame and the color enclosed by the outer frame determine the color of the flower. Since vector graphics can be obtained through formula calculation, the file size of vector graphics is generally small. The biggest advantage of vector graphics is that they will not be distorted no matter how much they are enlarged, reduced or rotated; the biggest disadvantage is that it is difficult to express realistic image effects with rich color levels.
Vector graphics will not be distorted no matter how large they are. Once the bitmap is enlarged, there will be obvious distortion, and pixels will appear one by one! Illustrator software introduction:
Adobe Illustrator is the industry standard vector illustration software for publishing, multimedia and online images. Whether you are a designer and professional illustrator producing line drawings for print publication, an artist producing multimedia images, or a producer of Internet pages or online content, you will find that Illustrator is more than just an art product tool. The software provides unparalleled precision and control over your line art, suitable for producing anything from small designs to large, complex projects.
As the world's most famous graphics software, Illustrator has occupied the majority of global vector editing software with its powerful functions and considerate user interface. According to incomplete statistics, 67 designers around the world are using Illustrator for artistic design! Especially based on the use of Adobe's patented PostScript technology, Illustrator has completely occupied the field of professional printing and publishing. Whether you are a line drawing designer and professional illustrator, an artist who produces multimedia images, or a producer of Internet pages or online content, after using Illustrator, you will find that its powerful functions and simple interface design style are superior to other similar ones. Software cannot compare! With the continuous development of network technology, Adobe is constantly adjusting the development direction of its products, and the many new features of Illustrator 10 have greatly strengthened its position in web design. Whether it is the final output of images on a web page or the release of vector graphics on a web page (SVG technology), it reflects Adobe's emphasis on network development!
Design and Drawing CorelDraw is a drawing and typesetting software. It is widely used in many fields such as trademark design, logo production, model drawing, illustration drawing, typesetting and color separation output. As a powerful drawing software, the fact that it is so popular is illustrated by the fact that almost all PCs used for commercial design and art design have CorelDraw installed!
CorelDraw is a software color based on vector graphics. Its functions can be roughly divided into two categories: drawing and typesetting.
CorelDraw has a well-designed interface and meticulous operation.
It provides designers with a complete set of drawing tools including circles, rectangles, polygons, squares, and spirals, and with shaping tools, more changes can be made to various basics, such as rounded rectangles, arcs, sectors, Star etc. At the same time, special brushes such as pressure pens, writing pens, sprayers, etc. are also provided to make full use of the computer's large amount of information processing and high random control capabilities.
To facilitate design needs, CorelDraw provides a complete set of graphics precise positioning and deformation control solutions. This brings great convenience to designs such as trademarks and logos that require accurate dimensions.
