This allows images to be kept in a format that is appropriate for a particular usage but simplifies the APIs that use encoded image data. This interface can ony be implemented by classes that are a part of the QTJava library; applications are not able to extend or apply usage of this interface, but can use the image encoding options that are provided. <P> To use objects that implement this interface you use the instanceof operator. The library ships with three types of objects that implement this interface. <UL> <LI>RawEncodedImage - a select set of subclasses that can contain encoded images. <li>ByteEncodedImage - the image data is held in a java byte array. <LI>IntEncodedImage - the image data is held in a java int array. </UL> <P> The EncodedImage class contains no information about the encoding format of the image. The particular encoding format of the image data is described by the encoded image's accompanying ImageDescription object, which contains all of the metadata that is required to completely describe the format and characteristics of the encoded image data. <P> If you are looking at pixel values directly you should bear a couple of things in mind:<BR> you may need to deal with the endian issue - they will be in a native endian format.<BR> if the description describes the image data format to be something other than raw pixels then the get methods are probably not very useful as you will not be looking at pixel values. <P><P><DL><DT><B>See Also: </B><DD><A HREF="../../quicktime/std/image/ImageDescription.html"><CODE>ImageDescription</CODE></A>, <A HREF="../../quicktime/util/ByteEncodedImage.html"><CODE>ByteEncodedImage</CODE></A>, <A HREF="../../quicktime/util/IntEncodedImage.html"><CODE>IntEncodedImage</CODE></A>, <A HREF="../../quicktime/util/RawEncodedImage.html"><CODE>RawEncodedImage</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#kRowBytesUnknown">kRowBytesUnknown</A></B></CODE><BR> This value is returned by an EncodedImage class from the getRowBytes() method if the encoded image does not know how many bytes per row or the data does not contain any extra byte data beyond the image encoding</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> byte</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#getByte(int)">getByte</A></B>(int offset)</CODE><BR> Returns the byte at the specified offset.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#getInt(int)">getInt</A></B>(int offset)</CODE><BR> Returns the int at the specified offset.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#getRowBytes()">getRowBytes</A></B>()</CODE><BR> Returns either kRowBytesUnknown or the number of bytes per row that the encoded image data is comprised of.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> short</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#getShort(int)">getShort</A></B>(int offset)</CODE><BR> Returns the short at the specified offset.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> int</CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/util/EncodedImage.html#getSize()">getSize</A></B>()</CODE><BR> Returns the size in bytes of the EncodedImage data.</TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><A NAME="field_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Field Detail</B></FONT></TD></TR></TABLE><A NAME="kRowBytesUnknown"><!-- --></A><H3>kRowBytesUnknown</H3><PRE>public static final int <B>kRowBytesUnknown</B></PRE><DL><DD>This value is returned by an EncodedImage class from the getRowBytes() method if the encoded image does not know how many bytes per row or the data does not contain any extra byte data beyond the image encoding</DL><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="getSize()"><!-- --></A><H3>getSize</H3><PRE>public int <B>getSize</B>()</PRE><DL><DD>Returns the size in bytes of the EncodedImage data.
