The material library website was founded on April 20th, 20th14. Is a large-scale comprehensive design China material website, which aims to provide free downloads of vector materials, icon materials, PSD materials, PS materials, flash materials, design appreciation, web page special effects, etc. for China webmasters. Provide vector graphics and vector materials, including ai, eps, cdr and other formats, exquisite and practical, free download.
Graphic matter, graphics are usually geometric maps of points, lines, surfaces and spaces, also known as vector maps. Vector diagram uses a set of instructions to describe the position, size and shape of all primitives, such as lines, circles, arcs, rectangles and curves. It has the characteristics of small volume, not easy to distort, concise and intuitive.
relevant information
Generally speaking, the graphics displayed in a computer can be divided into two categories-vector graphics and bitmap. Vector diagram uses straight lines and curves to describe graphics. The elements of these graphs are points, lines, rectangles, polygons, circles and arcs. , are calculated by mathematical formulas. For example, the vector diagram of flowers is actually the outline formed by line segments.
The color of flowers is determined by the color of the outer frame and the color surrounded by the outer frame. Because vector graphics can be calculated by formulas, the volume of vector graphics files is generally small. The greatest advantage of vector graphics is that it will not be distorted regardless of enlargement, reduction and rotation; The biggest drawback is that it is difficult to express realistic image effects with rich color levels.
