The combination graphic is Microsoft Office.
A graphic processing function in Word software, which can combine multiple independent shapes into a graphic object, and then move and modify the size of the combined graphic object.
A graph uses a set of instructions to describe the content of the graph, such as describing the position dimension and shape of various primitives that make up the graph. The description object can be scaled at will without distortion.
On the display side, graphics use special software to convert instructions describing graphics into shapes and colors on the screen. It is suitable for describing objects with uncomplicated contours and rich colors, such as geometric figures, engineering drawings, CAD and 3D modeling software.
Extended data
The connection between graphics and images:
In computer science,
There is a difference between graphics and images: graphics generally refer to pictures drawn by computers, such as straight lines, circles, arcs, arbitrary curves, charts and so on; An image refers to an actual scene picture captured by an input device or an arbitrary picture stored in digital form.
The image consists of some arranged pixels, and the storage formats in the computer are BMP, PCX, TIF, GIFD, etc. Generally, the amount of data is relatively large. It can not only show real photos, but also show some details of complex paintings, which is flexible and creative.
Different from images, the graphics file only records the algorithm of generating graphics and some characteristics of graphics, which is also called vector diagram.
. When the computer is restored, many specific small straight lines are used to connect adjacent features to form a curve. If the curve is a closed figure, you can also use the coloring algorithm to fill the color.
Its biggest advantage is that it is easy to move, compress, rotate and distort, and it is mainly used to represent wireframe drawings and engineering drawings.
, calligraphy, etc. Commonly used vector graphics files are 3DS (for 3D modeling), DXF (for CAD), WMF (for desktop publishing) and so on.
Graphics only save algorithms and feature points, so it takes up less storage space than a lot of data in bitmap (image). However, because the screen needs to be recalculated every time, the display speed is not as fast as that of the image.
In addition, when printing and enlarging, the graphic quality is high, and the bitmap (image) is often distorted. Graphics refer to two-dimensional space.
Several spatial shapes can be divided by contour lines, and graphics are part of space and have no spatial extensibility.
This is a limited recognizable shape.
