<div id=Content><div class="CClass"><div class=CTopic id=MainTopic><h1 class=CTitle><a name="mxPrintPreview"></a>mxPrintPreview</h1><div class=CBody><p>Implements printing of a diagram across multiple pages.&nbsp; The following opens a print preview for an existing graph:</p><blockquote><pre class="prettyprint">var preview = new mxPrintPreview(graph);
preview.open();</pre></blockquote><p>Use <a href="../util/mxUtils-js.html#mxUtils.getScaleForPageCount" class=LFunction id=link24 onMouseOver="ShowTip(event, 'tt23', 'link24')" onMouseOut="HideTip('tt23')">mxUtils.getScaleForPageCount</a> as follows in order to print the graph across a given number of pages:</p><blockquote><pre class="prettyprint">var pageCount = mxUtils.prompt('Enter page count', '1');
if (pageCount != null)
{
var scale = mxUtils.getScaleForPageCount(pageCount, graph);
var preview = new mxPrintPreview(graph, scale);
preview.open();
}</pre></blockquote><h4 class=CHeading>Headers</h4><p>Apart from setting the title argument in the mxPrintPreview constructor you can override <a href="#mxPrintPreview.renderPage" class=LFunction id=link25 onMouseOver="ShowTip(event, 'tt20', 'link25')" onMouseOut="HideTip('tt20')">renderPage</a> as follows to add a header to any page:</p><blockquote><pre class="prettyprint">var oldRenderPage = mxPrintPreview.prototype.renderPage;
mxPrintPreview.prototype.renderPage = function(w, h, dx, dy, scale, pageNumber)
{
var div = oldRenderPage.apply(this, arguments);
var header = document.createElement('div');
header.style.position = 'absolute';
header.style.top = '0px';
header.style.width = '100%';
header.style.textAlign = 'right';
mxUtils.write(header, 'Your header here - Page ' + pageNumber + ' / ' + this.pageCount);
div.firstChild.appendChild(header);
return div;
};</pre></blockquote><h4 class=CHeading>Page Format</h4><p>For landscape printing, use &lt;mxConstants.PAGE_FORMAT_A4_LANDSCAPE&gt; as the pageFormat in <a href="../util/mxUtils-js.html#mxUtils.getScaleForPageCount" class=LFunction id=link26 onMouseOver="ShowTip(event, 'tt23', 'link26')" onMouseOut="HideTip('tt23')">mxUtils.getScaleForPageCount</a> and <a href="#mxPrintPreview.mxPrintPreview" class=LFunction id=link27 onMouseOver="ShowTip(event, 'tt1', 'link27')" onMouseOut="HideTip('tt1')">mxPrintPreview</a>.&nbsp; Keep in mind that one can not set the defaults for the print dialog of the operating system from JavaScript so the user must manually choose a page format that matches this setting.</p><p>You can try passing the following CSS directive to <a href="#mxPrintPreview.open" class=LFunction id=link28 onMouseOver="ShowTip(event, 'tt17', 'link28')" onMouseOut="HideTip('tt17')">open</a> to set the page format in the print dialog to landscape.&nbsp; However, this CSS directive seems to be ignored in most major browsers, including IE.</p><blockquote><pre class="prettyprint">@page {
size: landscape;
}</pre></blockquote><p>Note that the print preview behaves differently in IE when used from the filesystem or via HTTP so printing should always be tested via HTTP.</p><p>If you are using a DOCTYPE in the source page you can override &lt;getDoctype&gt; and provide the same DOCTYPE for the print preview if required.&nbsp; Here is an example for IE8 standards mode.</p><blockquote><pre class="prettyprint">var preview = new mxPrintPreview(graph);
preview.getDoctype = function()
{
return '&lt;!--[if IE]&gt;&lt;meta http-equiv=&quot;X-UA-Compatible&quot; content=&quot;IE=5,IE=8&quot; &gt;&lt;![endif]--&gt;';
};
preview.open();</pre></blockquote><!--START_ND_SUMMARY--><div class=Summary><div class=STitle>Summary</div><div class=SBorder><table border=0 cellspacing=0 cellpadding=0 class=STable><tr class="SMain"><td class=SEntry><a href="#mxPrintPreview" >mxPrintPreview</a></td><td class=SDescription>Implements printing of a diagram across multiple pages. </td></tr><tr class="SGroup SIndent1"><td class=SEntry><a href="#mxPrintPreview.Functions" >Functions</a></td><td class=SDescription></td></tr><tr class="SFunction SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.mxPrintPreview" id=link1 onMouseOver="ShowTip(event, 'tt1', 'link1')" onMouseOut="HideTip('tt1')">mxPrintPreview</a></td><td class=SDescription>Constructs a new print preview for the given parameters.</td></tr><tr class="SGroup SIndent1"><td class=SEntry><a href="#mxPrintPreview.Variables" >Variables</a></td><td class=SDescription></td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.graph" id=link2 onMouseOver="ShowTip(event, 'tt2', 'link2')" onMouseOut="HideTip('tt2')">graph</a></td><td class=SDescription>Reference to the <a href="mxGraph-js.html#mxGraph" class=LClass id=link3 onMouseOver="ShowTip(event, 'tt3', 'link3')" onMouseOut="HideTip('tt3')">mxGraph</a> that should be previewed.</td></tr><tr class="SVariable SIndent2"><td class=SEntry><a href="#mxPrintPreview.pageFormat" id=link4 onMouseOver="ShowTip(event, 'tt4', 'link4')" onMouseOut="HideTip('tt4')">pageFormat</a></td><td class=SDescription>Holds the <a href="../util/mxRectangle-js.html#mxRectangle" class=LClass id=link5 onMouseOver="ShowTip(event, 'tt5', 'link5')" onMouseOut="HideTip('tt5')">mxRectangle</a> that defines the page format.</td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.scale" id=link6 onMouseOver="ShowTip(event, 'tt6', 'link6')" onMouseOut="HideTip('tt6')">scale</a></td><td class=SDescription>Holds the scale of the print preview.</td></tr><tr class="SVariable SIndent2"><td class=SEntry><a href="#mxPrintPreview.border" id=link7 onMouseOver="ShowTip(event, 'tt7', 'link7')" onMouseOut="HideTip('tt7')">border</a></td><td class=SDescription>The border inset around each side of every page in the preview. </td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.y0" id=link8 onMouseOver="ShowTip(event, 'tt8', 'link8')" onMouseOut="HideTip('tt8')">y0</a></td><td class=SDescription>Holds the vertical offset of the output.</td></tr><tr class="SVariable SIndent2"><td class=SEntry><a href="#mxPrintPreview.autoOrigin" id=link9 onMouseOver="ShowTip(event, 'tt9', 'link9')" onMouseOut="HideTip('tt9')">autoOrigin</a></td><td class=SDescription>Specifies if the origin should be automatically computed based on the top, left corner of the actual diagram contents. </td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.printOverlays" id=link10 onMouseOver="ShowTip(event, 'tt10', 'link10')" onMouseOut="HideTip('tt10')">printOverlays</a></td><td class=SDescription>Specifies if overlays should be printed. </td></tr><tr class="SVariable SIndent2"><td class=SEntry><a href="#mxPrintPreview.borderColor" id=link11 onMouseOver="ShowTip(event, 'tt11', 'link11')" onMouseOut="HideTip('tt11')">borderColor</a></td><td class=SDescription>Holds the color value for the page border.</td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.title" id=link12 onMouseOver="ShowTip(event, 'tt12', 'link12')" onMouseOut="HideTip('tt12')">title</a></td><td class=SDescription>Holds the title of the preview window.</td></tr><tr class="SVariable SIndent2"><td class=SEntry><a href="#mxPrintPreview.pageSelector" id=link13 onMouseOver="ShowTip(event, 'tt13', 'link13')" onMouseOut="HideTip('tt13')">pageSelector</a></td><td class=SDescription>Boolean that specifies if the page selector should be displayed. </td></tr><tr class="SVariable SIndent2 SMarked"><td class=SEntry><a href="#mxPrintPreview.wnd" id=link14 onMouseOver="ShowTip(event, 'tt14', 'link14')" onMou
