[Lead] Bessel curve tool is a very important drawing tool for drawing software, but many people feel difficult to master. This tutorial briefly introduces the function and use of the pen tools in Photoshop, I believe that everyone will have help. In Photoshop, how to get the desired curve? How to draw a complex path? How to edit existing path curves? With such a question, we invite the protagonist of this tutorial - pen tools. (This article is "situated" in the PHOTOSHOP toolbox with the latest photoshop7.0, the mouse right click on the 5 buttons contained in the steel pen tool (Figure 1), through these 5 The button can complete the pre-path of the path.
figure 1
By the right click on the button, the button above the pen tool will also appear again (as shown in Figure 2), combined with the partial button in front of the front pen to edit and modify the plotted path curve, complete the path Post adjustment of the curve. Figure 2 If the canvas is the stage of the pen tool, the path tuning is the background of the pen tool. Draw a good path curve is in the path tuning board, we can see the name of each path curve and thumbnails in the path tuning board.
Let's take a closer look at these and path-related tools and talents. First, the pen tool selects the pen tool, and you can see the options bar of the pen tool below the menu bar. The pen tool has two creative modes: Create a new shape layer and create a new working path (Figure 3). Figure 3 Creating a shape layer mode Creating a shape layer pattern can not only create a new path in the Path panel, but also create a shape layer in the chamfer panel, so if you choose to create a new shape layer option, you can create The shape, mixing mode, and opacity of the opacity are set before the shape layer. Check the Auto Add / Delete option, allow us to add or delete an anchor in the process of drawing the path, click some point on the path to add an anchor point, click the original anchor Click to delete it. If this item is not checked, you can pass a point on the path by the mouse. Select Add an anchor or right-click the original anchor point in the pop-up menu, select Remove anchor point in the pop-up menu. To achieve the same purpose. Check the rubber band option, let you see the path formed by the next anchor to be defined, so it will feel intuitive during the drawing process. Creating a new work path Click Creating a New Work Path button, a continuous click on the canvas can draw a wiring, by the end of the clicking on the pen button in the toolbar, you can also hold down the Ctrl key at the same time. Click, if you want to draw a polygon, when you close, close the mouse arrow to the starting point, when a small circle is appeared next to the mouse arrow, click the mouse button to close the path and. If you click and drag and drag and drop a curvature when you create an anchor, the curvature of the cage of the anchor can be adjusted to draw the path curve. Second, the node on the path node type and the conversion point tool path: the node (angular point) of the curvature tag (angular point), the two sides of the adjusted node (smooth point) and the two sides of the curvature respectively adjusted nodes (smoothing point) (Figure 4). Figure 4 The three nodes can be converted using a conversion point tool. Select the conversion point tool, click the two sides of the curvature together to adjust the anchor of the two sides of the curvature, which can be converted to a curvature tag mode, click the anchor and hold down the mouse button to drag, can make it The conversion is a two-sided curvature to adjust the way, and then the conversion point tool is used to move the tag, but also convert it to both sides of the curvature. When drawing the path curve, the two-sided curvature of the anchor is difficult to control, and we will explain how to accurately create this adjustment method by drawing a curve shown in Figure 5. Select the pen tool, press the Alt key first, then click and drag on the canvas, define the first anchor, release the mouse button, release the Alt key, click the second anchor position and drag When the curvature is appropriate, press and hold the Alt to move upward, it can be seen that the anchor is changed to both sides of the curvature, respectively, and when the curvature is adjusted, release the mouse button first, then release the ALT key, The position of the last anchor point is clicked and dragged to complete the drawing of this path curve. Figure 5. 3, free-pen and magnetic pen tools use a free-pen tool, we can draw a path curve as drawing on the canvas with a brush. You don't have to define the position of the anchor point because it is automatically added, and further adjustments are made after drawing. The number of automatic adding anchor points is determined by the curves and parameters of the Free Pen Tools option. The smaller the number of parameter values, the larger the number of automatic adding anchor points, the smaller, the scope of the curve intensity, the range of 0.5 pixels to 10 pixels between. If the magnetic option is checked, the Free Pen Tool will be converted to a magnetic pen tool (Figure 6), and the magnetic option is used to control the sensitivity of the magnetic pen tool to the edge capture of the image.
The width is the distance that the magnetic pen tool can capture, the range is from 1 to 40 pixels; the contrast is the contrast of the image edge, the range is 0 to 100%; the frequency value determines the density of the anchor, the range is 0 to 100%. Figure 6 Next we learn the use of magnetic pen tools by drawing graphics in Figure 7. Figure 7 first holds the Alt key, so that the magnetic pen tool draws a straight line, then click the right angle point of the graphics, when drawing the last straight line, release the Alt key, move along the edge of the graph, anchor Automatically add, when you can't capture the graphic comparison, you can manually click to add an anchor. When you need to draw a straight line, you need to press the ALT key in advance, and the last effect is shown in Figure 8. Figure 8I: Adding an anchor tool and deleting an anchor tool Adding an anchor tool and deleting anchor tools are used to use when the ready-made or plotted path curve is adjusted. For example, we have to draw a very complex shape, it is impossible to draw a success at once, you should draw a rough profile, then we can combine the addition of an anchor tool and deleting anchor tools to refine the final effect until the final effect. V. Path Selection Tools and Direct Select Tools Path Selection Tools and Direct Select Tools in the process of drawing and adjusting the path curve. Path Selection Tools You can select different path components (as shown in Figure 9). Figure 9
Check the display set bound box (Figure 10), click the setup box, the options of the Path Selection Tool becomes the transform value input strip. When the at least two path curves are selected, then click the Combination button in the option bar to a path, you can also align (at least two paths) and arrangement for the selected path application (at least three paths).
Figure 10
Direct selection tools play a pivotable role in the process of adjusting the path curve, because the location and curvature of the most important anchor point for the path curve are adjusted with direct selection tools. Sixth, the path tuning will be the stage of the pen tool, the path tuning is nothing more than the backstage of the pen tool. Drawing a good path curve is in the path tuning, we can see the name of each path curve and its thumbnail, and the current path is in the path tuning. In the pop-up menu of the path tale, there is a new path, a copy path, a storage path, and other commands. For convenience, we can also click the button below the tuning board to complete the appropriate operation (Figure 11).
Figure 11
A- uses the foreground color fill path (the white portion in the thumbnail is the paddle fill area). B- with a brush stroke path. C- Load the path as the selection. D- Generate a working path from the selection. E- Create a new path. F - Delete the current path. Pen tools in Photoshop are very wide, small to basic geometric shapes, large to complex curves, and pen tools can be done, and more patience, we can use the pen tools better.
