The Magick++ 388bc3ab67d818204fe5f0fe1dc29b873d37360461CristyAPI is enclosed within the <i>Magick</i> namespace so you must either 398bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyadd the prefix "<tt> Magick::</tt> " to each class/enumeration name or 408bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyadd 418bc3ab67d818204fe5f0fe1dc29b873d37360461Cristythe statement "<tt> using namespace Magick;</tt>" after including the <tt>Magick++.h</tt> 428bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyheader.</p> 438bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy<p>The preferred way to allocate Image objects is via automatic 448bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallocation (on the stack). There is no concern that allocating Image 458bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyobjects on the stack will excessively enlarge the stack since Magick++ 468bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallocates all large data objects (such as the actual image data) from 478bc3ab67d818204fe5f0fe1dc29b873d37360461Cristythe heap. Use of automatic allocation is preferred over explicit 488bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallocation (via <i>new</i>) since it is much less error prone and 498bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallows use of C++ scoping rules to avoid memory leaks. Use of automatic 508bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallocation allows Magick++ objects to be assigned and copied just like 518bc3ab67d818204fe5f0fe1dc29b873d37360461Cristythe C++ intrinsic data types (e.g. '<i>int</i> '), leading to clear and 528bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyeasy to read code. Use of automatic allocation leads to naturally 538bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyexception-safe code since if an exception is thrown, the object is 548bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyautomagically deallocated once the stack unwinds past the scope of the 558bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyallocation (not the case for objects allocated via <i>new</i> ). </p> 568bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy<p>Image is very easy to use.

If an odd number of values is provided, 27598bc3ab67d818204fe5f0fe1dc29b873d37360461Cristythen the list of values is repeated to yield an even number of 27608bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyvalues.  A typical strokeDashArray_ array might contain the 27618bc3ab67d818204fe5f0fe1dc29b873d37360461Cristymembers 5 3 2 0, where the zero value indicates the end of the pattern 27628bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyarray.</font></td> 27638bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy </tr> 27648bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <tr> 27658bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <td> 27668bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <center><a name="strokeLineCap"></a> <font size="-1">strokeLineCap</font></center> 27678bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy </td> 27688bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <td><font size="-1">LineCap</font></td> 27698bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <td><font size="-1">void</font></td> 27708bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <td><font size="-1">LineCap lineCap_</font></td> 27718bc3ab67d818204fe5f0fe1dc29b873d37360461Cristy <td><font size="-1">Specify the shape to be used at the corners 27728bc3ab67d818204fe5f0fe1dc29b873d37360461Cristyof paths (or other vector shapes) when they are stroked.
