4、本概念 使用選框工具創(chuàng)建選區(qū)時(shí)，要清楚，像素是圖像的基本組成單元，制作選區(qū)時(shí)不可能選擇半個(gè)像素。另外，選區(qū)可以有256個(gè)級別，這和通道中256 級灰度是對應(yīng)的，因?yàn)橛谢叶燃墑e，所以選區(qū)也是有級別之分。3.1Basic Concept When you create a constituency using the Marquee tool, make clear that the image pixel is the basic unit of production of constituencies can not select half pixel. In addition, the co

6、sic method of creating selection In Adobe Photoshop, it is necessary to edit the image of the partial, first through a variety of ways to select, which is said to create selection. With the Marquee tool to select the area you want to edit, you can move, copy, fill colors, or perform some special eff

7、ects. Production method of choice there are many, according to the specific circumstances of the need to use the most convenient way to create a selection. 規(guī)則選框工具 規(guī)則選框工具包括矩形選框工具、橢圓選框工具、單行選框工具和單列選框工具。Rules Marquee Tool Rules Marquee tool, including the Rectangular Marquee Tool, Elliptical Marquee too

Figure 3-1-27 路徑是由錨點(diǎn)組成的。錨點(diǎn)是定義路徑中每條線段開始和結(jié)束的點(diǎn)，可以通過它們來固定路徑。 一條開放路徑的開始和最后的錨點(diǎn)叫做端點(diǎn)。 如圖3-1-28所示，左圖中的圓圈表示選中的曲線路徑，兩邊的曲線錨點(diǎn)有把手；右圖中的圓圈表示沒選中的錨點(diǎn)，是空心的正方形。如圖

37、3-1-29所示，左圖中的圓圈表示選中的端點(diǎn)，右圖中的圓圈表示選中的錨點(diǎn)，所有選中的錨點(diǎn)都是以實(shí)心正方形表示的。圖3-1-28圖3-1-29 Path is formed by the anchor. Anchor is to define the path beginning and ending of each segment points to a fixed path through them. An open path to the beginning and end of the anchor is called the endpoint. As shown in Figure 3

38、-1-28, left in the circle that the selected path curve, the curve on both sides of the anchor with the handle; picture on the right of the circle that did not select the anchor, a hollow square. As shown in Figure 3-1-29, left in the circle that the selected endpoint to the right by the circle that

39、the anchor selected, all selected anchor are indicated by solid square. Figure 3-1-28Figure 3-1-29繪制直線繪制方法如下。1選中工具箱中的鋼筆工具 ，在其選項(xiàng)欄中單擊 圖標(biāo)，如圖3-1-30所示，表示用鋼筆工具繪制路徑而不是創(chuàng)建圖形或形狀圖層。圖3-1-302通過單擊鼠標(biāo)確定第一個(gè)錨點(diǎn)。移動(dòng)鋼筆工具到另外的位置，再次單擊鼠標(biāo)，兩個(gè)錨點(diǎn)之間就會(huì)以直線連接。按住Shift 鍵可保證生成的直線是水平線、垂直線或?yàn)?5倍數(shù)角度的直線。Draw linesDrawn as follows: 1Select t

40、he Pen tool in the toolbox, click the icon in the Options bar, as shown in Figure 3-1-30, that draw the path with the Pen tool to create graphics or shapes instead of layers. Figure 3-1-302By clicking the mouse to determine the first anchor. Move the pen tool to another location, another click of th

41、e mouse, will be a straight line between two anchor points connected. Hold down the Shift key to ensure that the resulting line is horizontal, vertical or multiple angles for the 45 line. 3繼續(xù)單擊鼠標(biāo)可創(chuàng)建另外的直線段。最后添加的錨點(diǎn)總是一個(gè)實(shí)心的正方形，表示該錨點(diǎn)是被選中的。如圖3-1-31所示。4要結(jié)束一條開放的路徑，可按住Ctrl鍵并單擊路徑以外的任意處。要封閉一條路徑，可將鋼筆工具放在第一個(gè)錨點(diǎn)上，

42、當(dāng)放置正確時(shí)，在鋼筆工具筆尖的右下角會(huì)出現(xiàn)一個(gè)小的圓圈，單擊鼠標(biāo)即可使路徑封閉。圖3-1-313Continue to click the mouse to create another straight line. Finally add the anchor is always a solid square, indicating that the anchor is selected. As shown in Figure 3-1-31.4. To end an open path, press and hold Ctrl key and click anywhere on the pa

43、th outside. To close a path, the pen tool can be placed on the first anchor, when placed correctly, the pen tool in the lower right corner tip of a small circle will appear, click the mouse to make the path closed. Figure 3-1-31繪制曲線 使用鋼筆工具繪制曲線，在曲線段上，每一個(gè)選定的錨點(diǎn)都顯示一條或兩條指向方向點(diǎn)的方向線。方向線和方向點(diǎn)的位置決定了曲線段的形狀，如圖3-

44、1-32所示。 方向線總是和曲線相切的。每一條方向線的斜率決定了曲線的斜率，移動(dòng)方向線可改變曲線的斜率，如圖3-1-33所示。每一條方向線的長度決定了曲線的高度或深度。圖3-1-32圖3-1-33Draw curve Using the pen tool for drawing curves, in the curve segment, each selected anchor are shown one or two points the direction to point the direction of line. Direction lines and direction point

45、s determines the location of the shape of curve segments, as shown in Figure 3-1-32. Direction lines and curves are always tangent. The slope of each line determines the direction of the slope, direction of movement can alter the slope line, as shown in Figure 3-1-33. The length of each direction li

46、ne determines the height or depth curve. Figure 3-1-32Figure 3-1-33 如圖3-1-34所示，左圖中的實(shí)心正方形表示的錨點(diǎn)是平滑點(diǎn)，右圖中的實(shí)心正方形表示的錨點(diǎn)是角點(diǎn)。 當(dāng)移動(dòng)平滑點(diǎn)上的一條方向線時(shí)，該點(diǎn)兩邊的曲線同時(shí)被調(diào)整。相反，當(dāng)移動(dòng)角點(diǎn)上的方向線時(shí)，只有和方向線一邊的曲線才進(jìn)行調(diào)整，如圖3-1-35所示。圖3-1-34圖3-1-35 As shown in Figure 3-1-34, left in the solid square that anchors a smooth point to the right by t

47、he solid square that anchors a corner. When moving a point in the direction of smooth lines, the point is adjusted at the same time on both sides of the curve. On the contrary, when the moving direction of the corner on the line, only one side of the curve and direction of line only to adjust, as sh

48、own in Figure 3-1-35. Figure 3-1-34Figure 3-1-35添加、刪除和轉(zhuǎn)換錨點(diǎn) 可以在任何路徑上添加或刪除錨點(diǎn)。添加錨點(diǎn)可以更好地控制路徑的形狀。同樣，可以刪除錨點(diǎn)來改變路徑的形狀或簡化路徑。如果路徑中包含太多的錨點(diǎn)，刪除不必要的錨點(diǎn)可減少路徑的復(fù)雜程度，這對簡化文件非常有幫助。 移動(dòng)和調(diào)整路徑 可以通過移動(dòng)兩個(gè)錨點(diǎn)之間的路徑片段、路徑上的錨點(diǎn)、錨點(diǎn)上的方向線和方向點(diǎn)來調(diào)整曲線路徑。 若要在繪制路徑時(shí)快速調(diào)整路徑，可在使用鋼筆工具的同時(shí)按住Command/Ctrl鍵，即可切換到箭頭狀的選擇工具，選中路徑片段或錨點(diǎn)后可直接進(jìn)行路徑調(diào)整，釋放Command/C

49、trl鍵就可恢復(fù)到鋼筆工具。Add, delete, and convert anchor Any path can be added or removed anchor. Add anchor can better control the shape of the path. Similarly, you can delete the anchor point to change the shape of the path or streamline the path. If the path contains too many anchors, remove unnecessary anc

50、hor can reduce the complexity of the path, which simplify the document very helpful. Move and adjust the path By moving the path between the two anchor segments, path anchor, anchor on the line and direction point the direction to adjust the curve of the path. To quickly adjust the path when drawing

51、 a path can use the pen tool, hold down the Command / Ctrl key, you can switch to the arrow-like selection tool, select the path segments or anchor points to adjust the path directly after the release of Command / Ctrl keys can be restored to the pen tool. 自由鋼筆工具 自由鋼筆工具的用法和使用鉛筆工具在紙上畫線一樣。路徑調(diào)板的使用 執(zhí)行“窗

52、口路徑”命令，就會(huì)出現(xiàn)“路徑”調(diào)板。 如圖3-1-36所示，在路徑調(diào)板的最下面有一排小圖標(biāo)，從左到右分別為：用前景色填充路徑、用畫筆描邊路徑、將路徑作為選區(qū)載入、從選區(qū)建立工作路徑、創(chuàng)建新路徑、刪除當(dāng)前路徑。圖3-1-36Free Pen tool Free use of pen tool and use the pencil tool to draw lines in the same paper.The use of the path palette Execute the window path command, will be a path palette.

54、 繪制好路徑后，可將路徑轉(zhuǎn)換成浮動(dòng)的選擇線。轉(zhuǎn)換的方法是直接用鼠標(biāo)將路徑調(diào)板中的路徑拖到調(diào)板下面的“將路徑作為選區(qū)載入”圖標(biāo)上。 也可在路徑調(diào)板右上角的彈出菜單中選擇“建立選區(qū)”命令，在出現(xiàn)的對話框中選擇“羽化半徑”的程度，如圖3-1-37所示。如果當(dāng)前圖像中已有選擇區(qū)域，可在“操作”選項(xiàng)區(qū)中選擇轉(zhuǎn)化后的選區(qū)和現(xiàn)有選區(qū)的相加、相減和相交。Choice between the path and the conversion Draw a path, the path can be converted into a floating selection line.
