Research on computer graphic and image design method based on visual communication technology

: The current computer graphics and image design is not only limited to the performance of images, more attention to visual communication, enhance the performance of images and visual communication effect. With the development and application of intelligent technology, the application of visual communication technology in computer graphic design will improve the aesthetic feeling of design works, at the same time, continue to enhance the ability of design appreciation and perception. By analyzing the overview of computer graphics and image design and Visual communication definition, and combining the relevant design elements, the paper analyzes the method of computer graphics and image design based on visual communication technology.


COMPUTER GRAPHIC AND IMAGE DESIGN ELEMENTS BASED ON VISUAL COMMUNICATION TECHNOLOGY
A very important role in visual communication is the element of choreography, especially in the use of computational image technology. The arrangement is to achieve the artistic process of effective request communication according to the goal request of information communication, through scientific arrangement and organization of the above visual elements, balance and coordination of each component structure. The practical application category of arranging elements is very extensive, using the transformation, overlap, isomorphism, deconstruction and deformation of graphic elements by using the graphic image processing software such as Photoshop and Painter, etc. , not only can it be personalized, but it also allows designers to use their creativity to rearrange each image or piece of information that has nothing to do with each other, the use of software modification technology and replacement functions of the image for a series of stylized modification, so that it has a different change effect.
The most basic human vision is the shape of the object and the color it produces when the human eye reacts to visible light. Color always radiates the magic charm, so in the whole process of visual communication within the role of color is self-evident. Through the use of image technology, three-dimensional design of the object, so that the object to form a three-dimensional effect and its effective color adjustment, hue, contrast, transparency and purity to adjust to the best, visually present in People's visual field of vision, so that they can have a very clear understanding of the object. Through the operation of image design, the designer fully integrates his design concept into the designed products, and through the adjustment of color information, reveals the complex color impression in nature in a regular way, display in people's vision, so that people can more directly understand the image of the information conveyed by the content.
The realization value of graphic elements is generally represented by the image production and debugging and the specific division of the image. After a series of images are collected, image technology will import them for adjustment and processing. Generally, it will be adjusted from two aspects. The first aspect is to fully satisfy the design, make a series of changes to the picture, especially filter effect processing, color adjustment and composition, etc. . The second aspect is the use of computer graphics to draw graphics, graphics and images in the computer is a very clear definition, generally divided into bitmaps and vector graphics. Bitmaps, as the name implies, are used to draw icons by bits, and vector maps are used to digitally record elements of geometric graphics. Bitmaps can be used to design the brightness of an image well, a vector diagram can completely show the original outline of a thing. In the text design can also be very good good good to use graphic design, operation and very simple, in some commonly used vector graphics software such as: C oreIDRAW, Illustrator, general toolbar window will have"Font size", "Color" and so on, we want to enter the text into the selected area directly after the art processing. The image design after processing these words will change a lot, in the visual impact of the effect has been greatly enhanced, making more vivid, so that the audience can more intuitively accept.

COMPUTER GRAPHIC AND IMAGE DESIGN METHOD BASED ON VISUAL COMMUNICATION TECHNOLOGY
Text design is an important part of graphic design, but also the main form of conveying design information. In graphic design, text design has been occupying an important position, but its design center has long been placed on the aesthetic treatment of text, the lack of necessary artistic connotation. On the basis of visual communication, text design will take information transmission and artistic expression as the core, and text font, size, spacing, combination of forms are only for the design of the basic part of services. As a result, text design can be more widely used in all kinds of billboards, highlighting the delivery of advertising information.
For goods, beautiful and attractive packaging is often a driving force to stimulate consumers to buy, so when plan design is applied to the design of goods packaging, we must pay full attention to the Visual communication, so as to improve the attractiveness of packaging to consumers. In fact, the application of Visual communication design in packaging design has been more mature, and has gone deep into all aspects of packaging design. For example, magazine covers in newsstands, leaflets on the streets, moon cake gift boxes in shopping malls, and boxes of digital products are all based on Visual communication, the corresponding graphics and images are designed and processed by computer technology. These graphic images in as much as possible highlight the image itself beautiful at the same time, but also with the packaging itself, will focus on the performance of the information itself.
Film and television design has always been the main place of application of plan design. Whether it is the traditional film and animation, or television advertising is essential, or now the network video, the visual communication based on the design plan has a strong dependence. Movies, anime, TV series, network video, and so often need to have a certain degree of artistic and artistic conception, and the screen is to show its artistic and artistic conception of the main form. In film and television design, the use of graphic design to design and process the screen, including the composition of the screen, color, near and far, etc. , can play a very good role in enhancing the artistic effect of the screen, furthermore, it has positive promoting significance to the overall promotion of the artistic quality and creative artistic conception of the film and television. Of course, the combination of Visual communication and graphic design has been used in numerous TV and web advertising applications. The design of images and forms of advertising can further highlight the creativity of advertising, thus display the advertisement and the product characteristic, fully attracts the audience's attention.

CONCLUSION
In order to optimize the graphic design system, designers should pay attention to the effective integration of computer graphic design and Visual communication design, and it is fully used in architectural design, clothing design, text design and packaging design and other fields. This method can not only improve the three-dimensional and aesthetic sense of the design works, but also maximize the appreciation and perception of the design effect. It can be seen that the above two design techniques have very high application value and application prospects, worthy of further promotion and application.
