<p>Image is the primary object in Magick++ and represents
a single image frame (see <a href="http://www.imagemagick.org/Magick++/ImageDesign.html">design</a> ). The
<a href="http://www.imagemagick.org/Magick++/STL.html">STL interface</a> <b>must</b> be used to operate on
image sequences or images (e.g. of format GIF, TIFF, MIFF, Postscript,
&amp; MNG) which are comprised of multiple image frames. Individual
frames of a multi-frame image may be requested by adding array-style
notation to the end of the file name (e.g. "animation.gif[3]" retrieves
the fourth frame of a GIF animation.  Various image manipulation
operations may be applied to the image. Attributes may be set on the
image to influence the operation of the manipulation operations. The <a
 href="http://www.imagemagick.org/Magick++/Pixels.html"> Pixels</a> class provides low-level access to
image
pixels. As a convenience, including <tt><font color="#663366">&lt;Magick++.h&gt;</font></tt>
is sufficient in order to use the complete Magick++ API. The Magick++
API is enclosed within the <i>Magick</i> namespace so you must either
add the prefix "<tt> Magick::</tt> " to each class/enumeration name or
add
the statement "<tt> using namespace Magick;</tt>" after including the <tt>Magick++.h</tt>
header.</p>
<p>The preferred way to allocate Image objects is via automatic
allocation (on the stack). There is no concern that allocating Image
objects on the stack will excessively enlarge the stack since Magick++
allocates all large data objects (such as the actual image data) from
the heap. Use of automatic allocation is preferred over explicit
allocation (via <i>new</i>) since it is much less error prone and
allows use of C++ scoping rules to avoid memory leaks. Use of automatic
allocation allows Magick++ objects to be assigned and copied just like
the C++ intrinsic data types (e.g. '<i>int</i> '), leading to clear and
easy to read code. Use of automatic allocation leads to naturally
exception-safe code since if an exception is thrown, the object is
automagically deallocated once the stack unwinds past the scope of the
allocation (not the case for objects allocated via <i>new</i> ). </p>
<p>Image is very easy to use. For example, here is a the source to a
program which reads an image, crops it, and writes it to a new file
(the
exception handling is optional but strongly recommended): </p>
<pre class="code">
#include &lt;Magick++.h> 
#include &lt;iostream> 
using namespace std; 
using namespace Magick; 
int main(int argc,char **argv) 
{ 
  InitializeMagick(*argv);

  // Construct the image object. Separating image construction from the 
  // the read operation ensures that a failure to read the image file 
  // doesn't render the image object useless. 
  Image image;
  try { 
    // Read a file into image object 
    image.read( "girl.gif" );

    // Crop the image to specified size (width, height, xOffset, yOffset)
    image.crop( Geometry(100,100, 100, 100) );

    // Write the image to a file 
    image.write( "x.gif" ); 
  }

The following is the source to a program which illustrates the use of
Magick++'s efficient reference-counted assignment and copy-constructor
operations which minimize use of memory and eliminate unnecessary copy
operations (allowing Image objects to be efficiently assigned, and
copied into containers).  The program accomplishes the
following:
<ol>
  <li> Read master image.</li>
  <li> Assign master image to second image.</li>
  <li> Resize second image to the size 640x480.</li>
  <li> Assign master image to a third image.</li>
  <li> Resize third image to the size 800x600.</li>
  <li> Write the second image to a file.</li>
  <li> Write the third image to a file.</li>
</ol>
<pre class="code">
#include <Magick++.h> 
#include <iostream> 
using namespace std; 
using namespace Magick; 
int main(int argc,char **argv) 
{ 
  InitializeMagick(*argv);

  Image master("horse.jpg"); 
  Image second = master; 
  second.resize("640x480"); 
  Image third = master; 
  third.resize("800x600"); 
  second.write("horse640x480.jpg"); 
  third.write("horse800x600.jpg"); 
  return 0; 
}
</pre>
During the entire operation, a maximum of three images exist in memory
and the image data is never copied.
<p>The following is the source for another simple program which creates
a 100 by 100 pixel white image with a red pixel in the center and
writes it to a file: </p>
<pre class="code">
#include <Magick++.h> 
using namespace std; 
using namespace Magick; 
int main(int argc,char **argv) 
{ 
  InitializeMagick(*argv);
  Image image( "100x100", "white" ); 
  image.pixelColor( 49, 49, "red" ); 
  image.write( "red_pixel.png" ); 
  return 0; 
}
</pre>
If you wanted to change the color image to grayscale, you could add the
lines:
<pre class="code">
image.quantizeColorSpace( GRAYColorspace ); 
image.quantizeColors( 256 ); 
image.quantize( );
</pre>
</p>
<p>or, more simply: </p>
<pre class="code">
 image.type( GrayscaleType );
</pre>
<p>prior to writing the image. </p>

<h2> <a name="BLOBs"></a> BLOBs</h2>
<div class="doc-section">
While encoded images (e.g. JPEG) are most often written-to and
read-from a disk file, encoded images may also reside in memory.
Encoded
images in memory are known as BLOBs (Binary Large OBjects) and may be
represented using the <a href="http://www.imagemagick.org/Magick++/Blob.html">Blob</a> class. The encoded
image may be initially placed in memory by reading it directly from a
file, reading the image from a database, memory-mapped from a disk
file, or could be written to memory by Magick++. Once the encoded image
has been placed within a Blob, it may be read into a Magick++ Image via
a <a href="Image++.html#constructor_blob">constructor</a> or <a href="Image++.html#read">read()</a>
. Likewise, a Magick++ image may be written to a Blob via <a
 href="Image++.html#write"> write()</a> .
<p>An example of using Image to write to a Blob follows: <br>
  </p>
<pre class="code">
#include <Magick++.h> 
using namespace std; 
using namespace Magick; 
int main(int argc,char **argv) 
{ 
  InitializeMagick(*argv);

  // Read GIF file from disk 
  Image image( "giraffe.gif" );
  // Write to BLOB in JPEG format 
  Blob blob; 
  image.magick( "JPEG" ) // Set JPEG output format 
  image.write( &blob );

  [ Use BLOB data (in JPEG format) here ]

  return 0; 
}
</pre>
<p><br>
likewise, to read an image from a Blob, you could use one of the
following examples: </p>
<p>[ <font color="#000000">Entry condition for the following examples
is that <i>data</i> is pointer to encoded image data and <i>length</i>
represents the size of the data</font> ] </p>
<pre class="code">
Blob blob( data, length ); 
Image image( blob );
</pre>
or
<pre class="code">
Blob blob( data, length ); 
Image image; 
image.read( blob);
</pre>
some images do not contain their size or format so the size and format must be specified in advance:
<pre class="code">
Blob blob( data, length ); 
Image image; 
image.size( "640x480") 
image.magick( "RGBA" ); 
image.read( blob);
</pre>

<h2> <a name="Image Manipulation Methods"></a> Image Manipulation Methods</h2>
<div class="doc-section">
<i>Image</i> supports access to all the single-image (versus
image-list) manipulation operations provided by the ImageMagick
library. If you
must process a multi-image file (such as an animation), the <a
 href="http://www.imagemagick.org/Magick++/STL.html"> STL interface</a> , which provides a multi-image
abstraction on top of <i>Image</i>, must be used.
<p>Image manipulation methods are very easy to use.  For example: </p>
<pre class="code">
Image image; 
image.read("myImage.tiff"); 
image.addNoise(GaussianNoise); 
image.write("myImage.tiff");
</pre>
adds gaussian noise to the image file "myImage.tiff".

<div class="doc-section">
Image attributes are set and obtained via methods in Image. Except for
methods which accept pointer arguments (e.g. c<tt>hromaBluePrimary)</tt>
all methods return attributes by value.
<p>Image attributes are easily used. For example, to set the resolution
of the TIFF file "file.tiff" to 150 dots-per-inch (DPI) in both the
horizontal and vertical directions, you can use the following example
code: </p>
<pre class="code">
string filename("file.tiff"); 
Image image; 
image.read(filename); 
image.resolutionUnits(PixelsPerInchResolution); 
image.density(Geometry(150,150));   // could also use image.density("150x150") 
image.write(filename)
</pre>
The supported image attributes and the method arguments required to
obtain them are shown in the following table: <br>

The channel modulus depth represents the minimum number of bits

depth
modifies the channel (i.e. discards resolution) if the requested
modulus
depth is less than the current modulus depth, otherwise the channel is
not altered. There is no attribute associated with the modulus depth so
the current modulus depth is obtained by inspecting the pixels. As a
result, the depth returned may be less than the most recently set
channel depth. Subsequent image processing may result in increasing the
channel depth.<br>

<h2> <a name="Raw Image Pixel Access"></a> Low-Level Image Pixel Access</h2>
<div class="doc-section">
Image pixels (of type <i><a href="http://www.imagemagick.org/Magick++/PixelPacket.html">PixelPacket</a> </i>)
may be accessed directly via the <i>Image Pixel Cache</i> .  The
image pixel cache is a rectangular window into the actual image pixels
(which may be in memory, memory-mapped from a disk file, or entirely on
disk). Two interfaces exist to access the <i>Image Pixel Cache.</i>
The
interface described here (part of the <i>Image</i> class) supports
only
one view at a time. See the <i><a href="http://www.imagemagick.org/Magick++/Pixels.html">Pixels</a> </i>
class for a more abstract interface which supports simultaneous pixel
views (up to the number of rows). As an analogy, the interface
described
here relates to the <i><a href="http://www.imagemagick.org/Magick++/Pixels.html">Pixels</a> </i> class as
stdio's gets() relates to fgets(). The <i><a href="http://www.imagemagick.org/Magick++/Pixels.html"> Pixels</a>
</i>class provides the more general form of the interface.
<p>Obtain existing image pixels via <i>getPixels()</i>. Create a new
pixel region using <i>setPixels().</i></p>
<p>In order to ensure that only the current generation of the image is
modified, the Image's <a href="Image++.html#modifyImage">modifyImage()</a> method
should be invoked to reduce the reference count on the underlying image
to one. If this is not done, then it is possible for a previous
generation of the image to be modified due to the use of reference
counting when copying or constructing an Image.<br>
</p>
<p>Depending on the capabilities of the operating system, and the
relationship of the window to the image, the pixel cache may be a copy
of the pixels in the selected window, or it may be the actual image
pixels. In any case calling <i>syncPixels()</i> insures that the base
image is updated with the contents of the modified pixel cache. The
method <i> readPixels()</i> supports copying foreign pixel data
formats
into the pixel cache according to the <i>QuantumTypes</i>. The method <i>writePixels()</i>
supports copying the pixels in the cache to a foreign pixel
representation according to the format specified by <i>QuantumTypes</i>.</p>
<p>The pixel region is effectively a small image in which the pixels
may be accessed, addressed, and updated, as shown in the following
example:
<pre class="code">
<p><img class="icon" src="../../api/Cache.png" name="Graphic1" width="254" border="0" /></p>
Image image("cow.png"); 
// Ensure that there are no other references to this image.
image.modifyImage();
// Set the image type to TrueColor DirectClass representation.
image.type(TrueColorType);
// Request pixel region with size 60x40, and top origin at 20x30 
ssize_t columns = 60; 
PixelPacket *pixel_cache = image.getPixels(20,30,columns,40); 
// Set pixel at column 5, and row 10 in the pixel cache to red. 
ssize_t column = 5; 
ssize_t row = 10; 
PixelPacket *pixel = pixel_cache+row*columns+column; 
*pixel = Color("red"); 
// Save changes to underlying image .
image.syncPixels();
  // Save updated image to file.
image.write("horse.png");
</pre>
</p>
<p>The image cache supports the following methods: <br>
