The <a href="Picture.html#sourceRect">sourceRect</a> property allows the programmer to specify a rectangular area of the source image that the Picture should display.</p> <p>The <a href="Picture.html#imageStretch">imageStretch</a> property allows an image to be resized inside of its bounding box.

This is useful in instances where images cannot be guaranteed to work, such as with user specified input. The error function can set the <a href="Picture.html#source">source</a> to a known good value, but care should be taken to avoid error infinite loops when doing so.</p> </div> </section> <section class="tsd-panel-group tsd-index-group"> <h2>Index</h2> <section class="tsd-panel tsd-index-panel"> <div class="tsd-index-content"> <section class="tsd-index-section "> <h3>Constructors</h3> <ul class="tsd-index-list"> <li class="tsd-kind-constructor tsd-parent-kind-class"><a href="Picture.html#constructor" class="tsd-kind-icon">constructor</a></li> </ul> </section> <section class="tsd-index-section "> <h3>Properties</h3> <ul class="tsd-index-list"> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#element" class="tsd-kind-icon">element</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#errorFunction" class="tsd-kind-icon">error<wbr>Function</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#flip" class="tsd-kind-icon">flip</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#imageAlignment" class="tsd-kind-icon">image<wbr>Alignment</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#imageStretch" class="tsd-kind-icon">image<wbr>Stretch</a></li> <li class="tsd-kind-get-signature tsd-parent-kind-class"><a href="Picture.html#naturalBounds" class="tsd-kind-icon">natural<wbr>Bounds</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#source" class="tsd-kind-icon">source</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#sourceCrossOrigin" class="tsd-kind-icon">source<wbr>Cross<wbr>Origin</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#sourceRect" class="tsd-kind-icon">source<wbr>Rect</a></li> <li class="tsd-kind-accessor tsd-parent-kind-class"><a href="Picture.html#successFunction" class="tsd-kind-icon">success<wbr>Function</a></li> </ul> </section> <section class="tsd-index-section "> <h3>Methods</h3> <ul class="tsd-index-list"> <li class="tsd-kind-method tsd-parent-kind-class"><a href="Picture.html#redraw" class="tsd-kind-icon">redraw</a></li> <li class="tsd-kind-method tsd-parent-kind-class"><a href="Picture.html#reloadSource" class="tsd-kind-icon">reload<wbr>Source</a></li> </ul> </section> </div> </section> </section> <section class="tsd-panel-group tsd-member-group "> <h2>Constructors</h2> <section class="tsd-panel tsd-member tsd-kind-constructor tsd-parent-kind-class"> <a name="constructor" class="tsd-anchor"></a> <h3> constructor </h3> <ul class="tsd-signatures tsd-kind-constructor tsd-parent-kind-class"> <li class="tsd-signature tsd-kind-icon">new <wbr>Picture<span class="tsd-signature-symbol">(</span><span class="tsd-signature-symbol">)</span><span class="tsd-signature-symbol">: </span><a href="Picture.html" class="tsd-signature-type">Picture</a></li> </ul> <ul class="tsd-descriptions"> <li class="tsd-description"> <div class="tsd-comment tsd-typography"> <p>The constructor creates a picture that shows nothing until the <a href="Picture.html#source">source</a> or <a href="Picture.html#element">element</a> is specified.
