A detailed explanation of bitmap and vector graphics in print design
The simplest difference between bitmap and vector is:
1. Vectors can be infinitely expanded without distortion. But not bitmaps.
2. The bitmap is made up of pixels. The loss map is made up of the loss line. This is a comparison of professional.
3. The bitmap can reflect more color contrast. The loss map is relatively small.
4. Vectors are more used for engineering drawings, such as ACD. However, bitmaps are more used in graphics, such as Photoshop. Book design bitmap and vector illustration
bitmap
Bitmaps use what we call pixel-by-cell dots to describe the picture. Your computer screen is a mesh that contains a large number of pixels. In the bitmap, the picture of the leaves we see above will be Determined by the position and color values of the pixels in each grid. The color of each point is fixed. When we watch the picture at a higher resolution, each small point looks like a mosaic of colors. Piece.
When you are doing a bitmap modification, originally you are in a little bit of the definition of the information of all the pixels in the picture, rather than the similar vector, you only need to define the general line segments and curves of the graph. Because the bits of the necessary scale Drawings are recorded little by little at a certain resolution, so the quality of these bitmap drawings is related to the resolution chosen when the drawing was generated. When the drawing is enlarged, it will appear on the edge of the drawing.
Vector illustration
Vectors use lines and curves to describe the image, so they are called vectors and they also contain color and position information. The leaves in the following example use a lot of points to connect curves to describe the outline of the leaves. Then according to the outline, Fill the inside of the image with a certain color.
When you edit vector graphics, you define the properties of the lines and curves that describe the shape of the graphic. These attributes will be recorded. Operations on vector graphics, such as moving, redefining dimensions, redefining shapes, or changing vectors The color of the graphics will not change the display quality of the vector graphics. You can also make a part of the graphics be hidden or change the transparency of the object through the overlapping of vector objects. The vector graphics are "resolution independent", which is Say, when you display or output an image, the quality of the image is not affected by the resolution of the device. In the example, the right image is a magnified vector image, and we see that the quality of the image is not affected.
Computers can display images in vector or bitmap format. Understanding the difference between the two can help you to better work efficiency. Fireworks lets you author images using a vector or bitmap tool in one piece of software, or import and process vector graphics and bitmap files generated by other applications. Fireworks provides bitmap editing mode and vector graphics editing mode.
