For example, a picture created under -Windows can be read on a Sun SPARC. -<p> Pictures are called meta-files on some platforms. -<p> TQt pictures use a proprietary binary format. Unlike native picture -(meta-file) formats on many window systems, TQt pictures have no -limitations regarding their contents. Everything that can be -painted can also be stored in a picture, e.g. fonts, pixmaps, -regions, transformed graphics, etc. -<p> TQPicture is an <a href="shclass.html">implicitly shared</a> class. -<p> Example of how to record a picture: -<pre> - TQPicture pic; - <a href="qpainter.html">TQPainter</a> p; - p.<a href="qpainter.html#begin">begin</a>( &pic ); // paint in picture - p.<a href="qpainter.html#drawEllipse">drawEllipse</a>( 10,20, 80,70 ); // draw an ellipse - p.<a href="qpainter.html#end">end</a>(); // painting done - pic.<a href="#save">save</a>( "drawing.pic" ); // save picture - </pre> - -<p> Example of how to replay a picture: -<pre> - TQPicture pic; - pic.<a href="#load">load</a>( "drawing.pic" ); // load picture - <a href="qpainter.html">TQPainter</a> p; - p.<a href="qpainter.html#begin">begin</a>( &myWidget ); // paint in myWidget - p.<a href="qpainter.html#drawPicture">drawPicture</a>( pic ); // draw the picture - p.<a href="qpainter.html#end">end</a>(); // painting done - </pre> - -<p> Pictures can also be drawn using <a href="#play">play</a>(). Some basic data about a -picture is available, for example, <a href="#size">size</a>(), <a href="#isNull">isNull</a>() and -<a href="#boundingRect">boundingRect</a>(). -<p> <p>See also <a href="graphics.html">Graphics Classes</a>, <a href="images.html">Image Processing Classes</a>, and <a href="shared.html">Implicitly and Explicitly Shared Classes</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQPicture"></a>TQPicture::TQPicture ( int formatVersion = -1 ) -</h3> -Constructs an empty picture. -<p> The <em>formatVersion</em> parameter may be used to <em>create</em> a TQPicture -that can be read by applications that are compiled with earlier -versions of TQt. -<ul> -<li> <em>formatVersion</em> == 1 is binary compatible with TQt 1.x and later. -<li> <em>formatVersion</em> == 2 is binary compatible with TQt 2.0.x and later. -<li> <em>formatVersion</em> == 3 is binary compatible with TQt 2.1.x and later. -<li> <em>formatVersion</em> == 4 is binary compatible with TQt 3.0.x and later. -<li> <em>formatVersion</em> == 5 is binary compatible with TQt 3.1. -</ul> -<p> Note that the default formatVersion is -1 which signifies the -current release, i.e. for TQt 3.1 a formatVersion of 5 is the same -as the default formatVersion of -1. -<p> Reading pictures generated by earlier versions of TQt is supported -and needs no special coding; the format is automatically detected. - -<h3 class=fn><a name="TQPicture-2"></a>TQPicture::TQPicture ( const <a href="qpicture.html">TQPicture</a> & pic ) -</h3> -Constructs a <a href="shclass.html">shallow copy</a> of <em>pic</em>. - -<h3 class=fn><a name="~TQPicture"></a>TQPicture::~TQPicture () -</h3> -Destroys the picture. - -<h3 class=fn><a href="qrect.html">TQRect</a> <a name="boundingRect"></a>TQPicture::boundingRect () const -</h3> -Returns the picture's bounding rectangle or an invalid rectangle -if the picture contains no data. - -<h3 class=fn><a href="qpicture.html">TQPicture</a> <a name="copy"></a>TQPicture::copy () const<tt> [protected]</tt> -</h3> -Returns a <a href="shclass.html">deep copy</a> of the picture. - -<h3 class=fn>const char * <a name="data"></a>TQPicture::data () const -</h3> - -<p> Returns a pointer to the picture data.
