矢量圖像

矢量圖像是一個收集個人的物體,而不是畫面元素。 A vector image can be composed of points connected by lines, or nodes (control points) connected by Bezier curves.矢量圖像可以組成點連線線,或節點(控制點)的連線, bezier曲線。
Vector Images: Advantages
用通俗的話語來說 就是矢量圖像最大的特點是不易失真 而缺點是 容量大 易損壞 顏色單調
矢量圖像:優勢
Each individual object contained in a vector image is defined by a mathematical equation.每個對象包含在矢量圖像是指由一個數學方程。 This means that vector images are not resolution dependent.這意味著載體的影像並不是第依賴性。 Thus, each vector object is scalable and can generally be resized without any loss of image quality.因此,每個矢量對象是可擴展性和大致可resized沒有任何損失的圖像質量。 As such, vector images are ideal for graphics such as maps and company logos that often require scaling.這樣,矢量圖像,非常適合圖形如地圖和公司標識,往往需要縮放。 However, it must be noted that when the sizes of some vector images are reduced too drastically, fine lines may disappear.但是,必須指出的是,當尺寸有些矢量圖像,減少過於急劇,細紋可能就此消失。 Too much enlargement can also make drawing mistakes apparent.太多的擴大也可以借鑑失誤明顯。
Each individual object may be edited to contain attributes such as outline, color and fill.每個對象可編輯包含屬性,例如大綱,顏色和填土。 Modifying the object's attributes will not change the basic object.修改對象的屬性是不會改變的基本對象。 The size of the object can also be transformed or shaped by using and adjusting its control points.大小的物體也可以被改造或塑造出來的使用和調整其控制點。
Vector images have no white pixel backgrounds.矢量圖像有沒有白紙像素的背景。 This means that you can put a vector object above another without blocking out the object underneath.這意味著你可以把一個向量對象上面又沒有堵出物體底下。
Vector images typically have small file sizes because one such file contains only the mathematical equations that determine the Bezier curves that define the image.矢量圖像通常有檔案較小,因為這樣一個檔案包含只有數學方程決定bezier曲線界定形象。 A vector image file does not contain the image itself.矢量圖像檔案不包含圖像本身。
Vector Images: Disadvantages
矢量圖像:缺點
Vector images, though they are highly defined, are not appropriate for use in producing realistic-looking photos and images.矢量圖像,雖然他們是非常確定的,並不適合用在生產實際看照片和圖像。 Vector images have solid color and gradient attributes but they are not conducive to uninterrupted sequences of subtle color tone and shade variations.矢量圖像有深厚的色彩和梯度屬性,但它們是不利於不間斷序列的微妙色調明暗變化。
There have been improvements to vector drawing software which enables users to approximate photorealistic vector objects.有改進的矢量繪圖軟體,使用戶能夠近似真實感矢量對象。 Attributes such as transparency can now be adjusted using vector imaging tools.屬性,如透明,現在可以調整使用矢量成像工具。 Bitmap textures can now also be applied to vector objects.點陣圖紋理,現在也可以套用於矢量對象。 Shading and blending are also some of the new vector imaging tools' functionalities.遮蔭和交融,也有一些的新載體成像工具的功能。 Still, most vector images look like sharply drawn cartoon images.儘管如此,美國多數矢量圖像樣子急劇得出的卡通形象。
Working with Vector Images
工作與矢量圖像
Vector images can be made through vector imaging software such as Adobe Illustrator, Corel Draw and Macromedia Freehand among others.矢量圖像可通過矢量成像軟體如adobe插畫, corel draw和macromedia的徒手畫等。 You can also scan pictures and graphics then convert it to vector images by using vector conversion software.您也可以掃描照片和圖表,然後轉換為矢量圖像採用矢量轉換軟體。
Vector images can be converted to bitmap images.矢量圖像可以轉換為點陣圖圖像。 Save the vector image first then specify the output bitmap image's resolution through the rasterizing process.拯救矢量圖像,然後先指定輸出點陣圖圖象的決議,通過生成的過程。 Pixel size, anti-aliasing and dithering of the output bitmap image are determined through this process.像素大小,抗鋸齒和抖動的輸出,點陣圖圖像有決心通過這個過程。 After conversion, it is best to save it in GIF or PNG formats if the resulting bitmap image is going to be used in the Web.經過換算,它是最好的挽救它在gif或png格式,如果由此產生的點陣圖圖像,是要用來在網站上。
Vector Images Formats
矢量圖像格式
There are various file formats for saving vector images.有各種檔案格式為節省矢量圖像。 EPS or Encapsulated PostScript format is the most versatile vector file format and is thus the most commonly used. eps或壓縮的postscript格式,是最多才多藝的矢量檔案格式,並因此是最常用的。 Another widely used vector image file format is PDF or Portable Document Format that was developed by Adobe.另一種廣泛使用的矢量圖像檔案格式是pdf或可攜式檔案格式,是由上市銷售。 One other file format for saving vector images is PICT which was developed by Macintosh.另一項檔案格式為節省矢量圖像pict ,這是由麥金塔。
矢量地圖被廣泛地運用於地理信息系統、移動信息服務、移動計算、車輛導航、網路製圖等研究和套用中。矢量地圖的存儲尤其是大比例尺矢量電子地圖的存儲對於提高移動終端的數據存儲量、加快矢量地圖的繪製速度、減少網路傳輸時間具有十分重要的作用。
