  33.             Image is the primary object in Magick++ and represents
    34. 

  34.             a single image frame (see <a href="https://imagemagick.org/Magick++/ImageDesign.html">design</a> ). The
    35. 

  35.             <a href="STL.html">STL interface</a> <b>must</b> be used to operate on
    36. 

  36.             image sequences or images (e.g. of format GIF, TIFF, MIFF, Postscript,
    37. 

  37.             &amp; MNG) which are comprized of multiple image frames. Individual
    38. 

  38.             frames of a multi-frame image may be requested by adding array-style
    39. 

  39.             notation to the end of the file name (e.g. "animation.gif[3]" retrieves
    40. 

  40.             the fourth frame of a GIF animation.&#160; Various image manipulation
    41. 

  41.             operations may be applied to the image. Attributes may be set on the
    42. 

  42.             image to influence the operation of the manipulation operations. The <a href="Pixels.html">Pixels</a> class provides low-level access to
    43.

    45. 

  45.             is sufficient in order to use the complete Magick++ API. The Magick++
    46. 

  46.             API is enclosed within the <i>Magick</i> namespace so you must either
    47. 

  47.             add the prefix "<tt> Magick::</tt> " to each class/enumeration name or
    48. 

  48.             add
    49. 

  49.             the statement "<tt> using namespace Magick;</tt>" after including the <tt>Magick++.h</tt>

    53. 

  53.             The preferred way to allocate Image objects is via automatic
    54. 

  54.             allocation (on the stack). There is no concern that allocating Image
    55. 

  55.             objects on the stack will excessively enlarge the stack since Magick++
    56. 

  56.             allocates all large data objects (such as the actual image data) from
    57. 

  57.             the heap. Use of automatic allocation is preferred over explicit
    58. 

  58.             allocation (via <i>new</i>) since it is much less error prone and
    59. 

  59.             allows use of C++ scoping rules to avoid memory leaks. Use of automatic
    60. 

  60.             allocation allows Magick++ objects to be assigned and copied just like
    61. 

  61.             the C++ intrinsic data types (e.g. '<i>int</i> '), leading to clear and
    62. 

  62.             easy to read code. Use of automatic allocation leads to naturally
    63. 

  63.             exception-safe code since if an exception is thrown, the object is
    64. 

  64.             automagically deallocated once the stack unwinds past the scope of the
    65. 

  65.             allocation (not the case for objects allocated via <i>new</i> ).
