The QDGraphics from... calls will return the existing destination graphics of the first supplied object. For the fromNativeGraphics this will always be an on screen graphics (in traditional QuickDraw parlance a CGrafPort). For the other calls the type of the QDGraphics returned is dependant on the destination graphics of the object that the application has established.<P><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/qd/QDGraphics.html#kDefaultPixelFormat">kDefaultPixelFormat</A></B></CODE><BR> This is the default pixel format that is used to create offscreen graphics contexts when no format is used.</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/qd/QDGraphics.html#kNativeSize">kNativeSize</A></B></CODE><BR> This is the size (the number of bytes) that are required for this class</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../quicktime/qd/QDGraphics.html">QDGraphics</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/qd/QDGraphics.html#scratch">scratch</A></B></CODE><BR> This holds a reference to the scratchGWorld that you can use manually in calls such as Movie.setGWorld.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../quicktime/qd/QDGraphics.html">QDGraphics</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../quicktime/qd/QDGraphics.html#validScratch">validScratch</A></B></CODE><BR> This holds a reference to the scratchGWorld that you can use as a temporary destination graphics and still be considered as a valid destination graphics by QTDrawable objects.</TD></TR></TABLE> <A NAME="fields_inherited_from_class_quicktime.jdirect.QuickTimeLib"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface quicktime.jdirect.<A HREF="../../quicktime/jdirect/QuickTimeLib.html">QuickTimeLib</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../quicktime/jdirect/QuickTimeLib.html#JDirect_MacOSX">JDirect_MacOSX</A>, <A HREF="../../quicktime/jdirect/QuickTimeLib.html#libraryInstance">libraryInstance</A>, <A HREF="../../quicktime/jdirect/QuickTimeLib.html#name">name</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_quicktime.jdirect.QTStreamingLib"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface quicktime.jdirect.<A HREF="../../quicktime/jdirect/QTStreamingLib.html">QTStreamingLib</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../quicktime/jdirect/QTStreamingLib.html#JDirect_MacOSX">JDirect_MacOSX</A>, <A HREF="../../quicktime/jdirect/QTStreamingLib.html#libraryInstance">libraryInstance</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../quicktime/qd/QDGraphics.html#QDGraphics(quicktime.std.qtcomponents.ImageCompressionDialog, quicktime.qd.QDRect, int)">QDGraphics</A></B>(<A HREF="../../quicktime/std/qtcomponents/ImageCompressionDialog.html">ImageCompressionDialog</A> d, <A HREF="../../quicktime/qd/QDRect.html">QDRect</A> rp, int flags)</CODE><BR> Creates an offscreen QDGraphics based on the current compression settings.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../quicktime/qd/QDGraphics.html#QDGraphics(quicktime.std.image.ImageDescription, int)">QDGraphics</A></B>(<A HREF="../../quicktime/std/image/ImageDescription.html">ImageDescription</A> id, int flags)</CODE><BR> Creates an offscreen QDGraphics object from the width, height, depth, and color table of a specified image description structure.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../quicktime/qd/QDGraphics.html#QDGraphics(int, quicktime.qd.QDRect)">QDGraphics</A></B>(int pixelFormat, <A HREF="../../quicktime/qd/QDRect.html">QDRect</A> bounds)</CODE><BR> An offscreen graphics world in Color QuickDraw contains a GWorld -
