Vector graphics on the description of several concepts


FONT class = unnamed1 size =- 1> What are vector images?
Vector images, also known as object-oriented images or graphics images, a series of mathematically defined by a line connecting the points. Graphic elements vector file as an object. Each object is a self-contained entity, it has the color, shape, contour, size and screen position and other attributes. Since every object is a self-contained entity, it can maintain its original clarity and curvature, while many mobile and change its properties, without affecting the Legend of the other objects. These features make the vector-based program suitable for the legend and three-dimensional modeling, because they are usually required to create and manipulate a single object. Vector-based graphics has nothing to do with the resolution. This means that they can be the highest resolution display to the output device.
What are bitmap images?
And above compared to vector-based drawing program like Photoshop photo editing program that is used for processing the bitmap image. When you deal with a bitmap image, small details can be optimized to carry out significant changes, and enhancement. Bitmap images, also known as dot matrix image or draw images, is called pixels (picture elements) composed of a single point. These points can be arranged in different patterns and coloring to form. When the enlarged bitmap, you can see the whole image which constitutes the numerous single box. Expand the size of the effect of the bitmap more individual pixels, lines and shapes seem so uneven. However, if a little far from the location of watching it, bitmap image of the color and shape it seems is continuous. Since each pixel is individually dyed, you can order each time the frequency of operation of a pixel generated selected area near photo-realistic effects, such as the deepening shadows and add color. Will also reduce the size of original image bitmap distortion, because it is by reducing the pixels to make the entire image is small. Similarly, the bitmap image is a collection of pixels arranged in the form of created, it can not operate independently (eg, mobile) Office location map.
Why focus on when dealing with bitmap consider the resolution?
Handling bitmaps, the output quality of the image depends on the processing level of the beginning of the resolution settings. Resolution is a general term that refers to an image file contains the details and information, size, and input, output, or display device to generate the level of detail. Operation bitmap, the resolution will affect the quality of the final output will also affect the size of the file. Handling bitmaps need to think twice, because the choice of the resolution to image the entire process is usually accompanied by the document. Whether in a 300 dpi printer or a typesetting device a 2570dpi print bitmap file, the file is always to create the image size set by resolution printing, unless the sub printer encyclical real ideological choice between Tuo Yuan province H Farm Direct Quan 顛?M 顜?Kangzhangsuzhui female swan spring Tuiliaohuangxian Yunjingnanghuang 願?顑?knock plexus lie 顎?care ridge Bru skull Egypt 顑?weighbridges 顎?private Zhuanjiasongmu straight tube feces Yuan Huang 顑?Pufuzhiyuan hand 顔?Lai Yun Huang Tomb thereupon lazy O Karma off season rates cylinder Qin Huai NIE palpitations straw yo? br> about objects in CorelDRAW
CorelDRAW The object can be any basic drawing element or a line of text, such as line, ellipse, polygon, rectangle, mark the word line or line art, etc.. After you finish creating a simple object, you can define its characteristics, such as fill color, outline color, curve smoothness, etc., and special effects of its application. In this information, including the location of the object in the screen, create it in the order, and define the attribute values are described as part of the object. This means that when the operation object (such as moving objects), CorelDRAW will rebuild its shape and all the attributes.
Object can have a closed path or an open path. A group object is composed of one or more objects. When using the selection tool to select an object, you can select the frame around it to identify it. Elected in an object, select the box corner and the midpoint of the filling box will appear 8. Each individual object has its own selection box. When using the "group" command to two or more objects are combined, it will create a group, may take it as an object to select and operate. Objects from the path of composition, these paths form the contours and boundaries of its. A path constituted by a single or a few segments. Endpoint of each segment has a hollow box, called the node. Can use the shape tool to select an object node, thus changing its overall shape and bending angle.
Open path and closed path object object What is the difference?
Open path object is the intersection of the two endpoints. Closed path object is to constitute the two ends of a row that the path of the object. Open path object can be a straight line may be curved, for example, hand-painted tools to create lines, use the Bezier tool to create lines or thread tool to create the thread lines. However, with the "Hand Tools" or "Bezier curve tool" when to start and finish together can create a closed path. Closed path objects, including round, square, grid, natural document line, polygon and star and so on. Closed path object is filled, and open path to the object can not be filled.
