<divid=Content><divclass="CClass"><divclass=CTopicid=MainTopic><h1class=CTitle><aname="mxPrintPreview"></a>mxPrintPreview</h1><divclass=CBody><p>Implements printing of a diagram across multiple pages. The following opens a print preview for an existing graph:</p><blockquote><preclass="prettyprint">var preview = new mxPrintPreview(graph);
preview.open();</pre></blockquote><p>Use <ahref="../util/mxUtils-js.html#mxUtils.getScaleForPageCount"class=LFunctionid=link43onMouseOver="ShowTip(event, 'tt40', 'link43')"onMouseOut="HideTip('tt40')">mxUtils.getScaleForPageCount</a> as follows in order to print the graph across a given number of pages:</p><blockquote><preclass="prettyprint">var pageCount = mxUtils.prompt('Enter page count', '1');
}</pre></blockquote><h4class=CHeading>Additional pages</h4><p>To add additional pages before and after the output, <ahref="#mxPrintPreview.getCoverPages"class=LFunctionid=link44onMouseOver="ShowTip(event, 'tt36', 'link44')"onMouseOut="HideTip('tt36')">getCoverPages</a> and <ahref="#mxPrintPreview.getAppendices"class=LFunctionid=link45onMouseOver="ShowTip(event, 'tt37', 'link45')"onMouseOut="HideTip('tt37')">getAppendices</a> can be used, respectively.</p><blockquote><preclass="prettyprint">var preview = new mxPrintPreview(graph, 1);
preview.open();</pre></blockquote><h4class=CHeading>CSS</h4><p>The CSS from the original page is not carried over to the print preview. To add CSS to the page, use the css argument in the <ahref="#mxPrintPreview.open"class=LFunctionid=link46onMouseOver="ShowTip(event, 'tt22', 'link46')"onMouseOut="HideTip('tt22')">open</a> function or override <ahref="#mxPrintPreview.writeHead"class=LFunctionid=link47onMouseOver="ShowTip(event, 'tt30', 'link47')"onMouseOut="HideTip('tt30')">writeHead</a> to add the respective link tags as follows:</p><blockquote><preclass="prettyprint">var writeHead = preview.writeHead;
};</pre></blockquote><h4class=CHeading>Padding</h4><p>To add a padding to the page in the preview (but not the print output), use the following code:</p><blockquote><preclass="prettyprint">preview.writeHead = function(doc)
};</pre></blockquote><h4class=CHeading>Headers</h4><p>Apart from setting the title argument in the mxPrintPreview constructor you can override <ahref="#mxPrintPreview.renderPage"class=LFunctionid=link48onMouseOver="ShowTip(event, 'tt32', 'link48')"onMouseOut="HideTip('tt32')">renderPage</a> as follows to add a header to any page:</p><blockquote><preclass="prettyprint">var oldRenderPage = mxPrintPreview.prototype.renderPage;
};</pre></blockquote><p>The pageNumber argument contains the number of the current page, starting at 1. To display a header on the first page only, check pageNumber and add a vertical offset in the constructor call for the height of the header.</p><h4class=CHeading>Page Format</h4><p>For landscape printing, use <mxConstants.PAGE_FORMAT_A4_LANDSCAPE> as the pageFormat in <ahref="../util/mxUtils-js.html#mxUtils.getScaleForPageCount"class=LFunctionid=link49onMouseOver="ShowTip(event, 'tt40', 'link49')"onMouseOut="HideTip('tt40')">mxUtils.getScaleForPageCount</a> and <ahref="#mxPrintPreview.mxPrintPreview"class=LFunctionid=link50onMouseOver="ShowTip(event, 'tt1', 'link50')"onMouseOut="HideTip('tt1')">mxPrintPreview</a>. 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 <ahref="#mxPrintPreview.open"class=LFunctionid=link51onMouseOver="ShowTip(event, 'tt22', 'link51')"onMouseOut="HideTip('tt22')">open</a> to set the page format in the print dialog to landscape. However, this CSS directive seems to be ignored in most major browsers, including IE.</p><blockquote><preclass="prettyprint">@page {
}</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 <getDoctype> and provide the same DOCTYPE for the print preview if required. Here is an example for IE8 standards mode.</p><blockquote><preclass="prettyprint">var preview = new mxPrintPreview(graph);
preview.open();</pre></blockquote><!--START_ND_SUMMARY--><divclass=Summary><divclass=STitle>Summary</div><divclass=SBorder><tableborder=0cellspacing=0cellpadding=0class=STable><trclass="SMain"><tdclass=SEntry><ahref="#mxPrintPreview">mxPrintPreview</a></td><tdclass=SDescription>Implements printing of a diagram across multiple pages. </td></tr><trclass="SGroup SIndent1"><tdclass=SEntry><ahref="#mxPrintPreview.Functions">Functions</a></td><tdclass=SDescription></td></tr><trclass="SFunction SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.mxPrintPreview"id=link1onMouseOver="ShowTip(event, 'tt1', 'link1')"onMouseOut="HideTip('tt1')">mxPrintPreview</a></td><tdclass=SDescription>Constructs a new print preview for the given parameters.</td></tr><trclass="SGroup SIndent1"><tdclass=SEntry><ahref="#mxPrintPreview.Variables">Variables</a></td><tdclass=SDescription></td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.graph"id=link2onMouseOver="ShowTip(event, 'tt2', 'link2')"onMouseOut="HideTip('tt2')">graph</a></td><tdclass=SDescription>Reference to the <ahref="mxGraph-js.html#mxGraph"class=LClassid=link3onMouseOver="ShowTip(event, 'tt3', 'link3')"onMouseOut="HideTip('tt3')">mxGraph</a> that should be previewed.</td></tr><trclass="SVariable SIndent2"><tdclass=SEntry><ahref="#mxPrintPreview.pageFormat"id=link4onMouseOver="ShowTip(event, 'tt4', 'link4')"onMouseOut="HideTip('tt4')">pageFormat</a></td><tdclass=SDescription>Holds the <ahref="../util/mxRectangle-js.html#mxRectangle"class=LClassid=link5onMouseOver="ShowTip(event, 'tt5', 'link5')"onMouseOut="HideTip('tt5')">mxRectangle</a> that defines the page format.</td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.scale"id=link6onMouseOver="ShowTip(event, 'tt6', 'link6')"onMouseOut="HideTip('tt6')">scale</a></td><tdclass=SDescription>Holds the scale of the print preview.</td></tr><trclass="SVariable SIndent2"><tdclass=SEntry><ahref="#mxPrintPreview.border"id=link7onMouseOver="ShowTip(event, 'tt7', 'link7')"onMouseOut="HideTip('tt7')">border</a></td><tdclass=SDescription>The border inset around each side of every page in the preview. </td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.marginTop"id=link8onMouseOver="ShowTip(event, 'tt8', 'link8')"onMouseOut="HideTip('tt8')">marginTop</a></td><tdclass=SDescription>The margin at the top of the page (number). </td></tr><trclass="SVariable SIndent2"><tdclass=SEntry><ahref="#mxPrintPreview.marginBottom"id=link9onMouseOver="ShowTip(event, 'tt9', 'link9')"onMouseOut="HideTip('tt9')">marginBottom</a></td><tdclass=SDescription>The margin at the bottom of the page (number). </td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.x0"id=link10onMouseOver="ShowTip(event, 'tt10', 'link10')"onMouseOut="HideTip('tt10')">x0</a></td><tdclass=SDescription>Holds the horizontal offset of the output.</td></tr><trclass="SVariable SIndent2"><tdclass=SEntry><ahref="#mxPrintPreview.y0"id=link11onMouseOver="ShowTip(event, 'tt11', 'link11')"onMouseOut="HideTip('tt11')">y0</a></td><tdclass=SDescription>Holds the vertical offset of the output.</td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.autoOrigin"id=link12onMouseOver="ShowTip(event, 'tt12', 'link12')"onMouseOut="HideTip('tt12')">autoOrigin</a></td><tdclass=SDescription>Specifies if the origin should be automatically computed based on the top, left corner of the actual diagram contents. </td></tr><trclass="SVariable SIndent2"><tdclass=SEntry><ahref="#mxPrintPreview.printOverlays"id=link13onMouseOver="ShowTip(event, 'tt13', 'link13')"onMouseOut="HideTip('tt13')">printOverlays</a></td><tdclass=SDescription>Specifies if overlays should be printed. </td></tr><trclass="SVariable SIndent2 SMarked"><tdclass=SEntry><ahref="#mxPrintPreview.printControls"id=link14onMouseOver="ShowTip(event, 'tt14', 'link14')"onMouseOut="HideT
