<B>原理:</B><BR>利用自由形变（Ctrl+T）改变路径的宽、高、旋转角度、水平＆垂直斜切的值，然后利用Ctrl＋Shift＋Alt＋T（再次变换复制的象素数据并建立一个副本）来变换实现。<BR>现在从简到难举例如说明一下原理的应用，知道了原理应用，效果就是用心和创意的问题了。<BR><B>例一</B><BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016459.gif')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016459.gif" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>1 . 打开ps，建立一个800×600的图像，设“前景色”为白色，“背景色”为黑色（为了对比强烈），并新建“图层1”填充背景色（Ctrl+Delete）。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016999.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016999.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>2 . 选择“椭圆工具”，在选项栏中选择“路径”。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016349.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145016349.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>3 . 在“图层面板”中选择“路径”选项卡，新建“路径”，用“椭圆工具”画一个椭圆形“路径1”。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017550.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017550.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>4 . 选择“路径1”，“编辑”-&gt;“自由变换路径”（Ctrl+T）,并设置参数如图，点击确定（Enter）。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017663.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017663.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>5 . N次按Ctrl＋Shift＋Alt＋T，得到如图：<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017335.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017335.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>6 . 选择“路径选择工具”，选择所有途径。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017410.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017410.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017421.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017421.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>7 . 选择“图层”选项卡，新建“图层2”，再选择“路径”选项卡，“用画笔描边路径”。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017515.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017515.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>8 . 取消对“路径1”的选择，结果如例一图。 <BR>还有一种实现方法原理一样，只是利用“椭圆选择工具”选择椭圆区域，进行“描边”，Ctrl＋T设置参数，Ctrl＋Shift＋Alt＋T变换，结果如图：<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017897.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017897.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>大家会发现，利用描边得到的线性图形变形过程，图形本身的粗细发生了变形，所以两个有些区别，当然各有风味，用于不同的需求下。<BR><B>注意：</B>利用Ctrl＋Shift＋Alt＋T变换线性图形时，如果线性图形是被选择状态，则新生存的图形在原图形上，否则每次变换则复制变换数据且新建一个图层。<BR><B>例二</B><BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017280.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017280.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>1 . 选择“钢笔工具”。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017498.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145017498.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>2 . 新建“路径2”，并画直线路径，调整如图。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018306.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018306.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>3 . 选择所有路径，Ctrl＋T设置参数如图。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018130.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018130.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>4 . Ctrl＋Shift＋Alt＋T变换，新建“图层3”，运行“用画笔描边路径”，结果如例二图。 <BR>另一种方法，就是用“钢笔工具”画路径，然后“用画笔描边路径”，直接在线性图形上运行Ctrl＋T设置参数，Ctrl＋Shift＋Alt＋T变换，结果如图。这个时候就可以明显发现，外面的线条边的毛糙了。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018291.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018291.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR><BR><B>例三</B> <BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018824.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018824.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>1 . 选择“椭圆工具”，用“椭圆工具”画一个椭圆形“路径3”。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018220.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018220.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>2 . Ctrl+T,设置参数如图，注意“参考点位置”的设定。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018853.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018853.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>3 . 运行lCtrl＋Shift＋Alt＋T变换，结果如图。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018438.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018438.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>4. “视图”-&gt;“标尺”（Ctrl+R）,设置中心参考线如图。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018285.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018285.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>5 . 选择所有的路径，Ctrl+T，调整变换“参考点位置”，并设置参数如图。<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018567.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145018567.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019263.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019263.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>6 . 运行lCtrl＋Shift＋Alt＋T变换，然后新建图层，“用画笔描边路径”，结果如图：<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019106.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019106.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR>同样也存在利用“椭圆选择工具”选择椭圆区域，进行“描边”，Ctrl＋T设置参数，Ctrl＋Shift＋Alt＋T变换，结果如图：<BR><IMG onmousewheel="return imgzoom(this)" onmouseover="attachimg(this, 'mouseover')" onclick="attachimg(this, 'click', 'http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019115.jpg')" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200704/20070410145019115.jpg" onload="attachimg(this, 'load', 'Click here to open new window\nCTRL+Mouse wheel to zoom in/out')" border=0><BR><B>总结</B><BR>路径不仅控制了变换过程中线条出现的锯齿和变形，而且也有更多的灵活性，笔的样式多样可以产生多样的图形。 <BR>通过改变自由变换的参数，建立多种不同的图形组合，循环利用Ctrl＋T和Ctrl＋Shift＋Alt＋T，可以产生很多绚丽的线条效果。<BR><script language="JavaScript" src="http://www.16xx8.com/bbs/10.js"></script><BR>
