<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Image</title> <link type="text/css" rel="stylesheet" href="../fpdf.css"> </head> <body> <h1>Image</h1> <code>Image(<b>string</b> file [, <b>float</b> x [, <b>float</b> y [, <b>float</b> w [, <b>float</b> h [, <b>string</b> type [, <b>mixed</b> link]]]]]])</code> <h2>Description</h2> Puts an image. The size it will take on the page can be specified in different ways: <ul> <li>explicit width and height (expressed in user unit or dpi)</li> <li>one explicit dimension, the other being calculated automatically in order to keep the original proportions</li> <li>no explicit dimension, in which case the image is put at 96 dpi</li> </ul> Supported formats are JPEG, PNG and GIF. The GD extension is required for GIF. <br> <br> For JPEGs, all flavors are allowed: <ul> <li>gray scales</li> <li>true colors (24 bits)</li> <li>CMYK (32 bits)</li> </ul> For PNGs, are allowed: <ul> <li>gray scales on at most 8 bits (256 levels)</li> <li>indexed colors</li> <li>true colors (24 bits)</li> </ul> For GIFs: in case of an animated GIF, only the first frame is displayed.<br> <br> Transparency is supported.<br> <br> The format can be specified explicitly or inferred from the file extension.<br> <br> It is possible to put a link on the image.<br> <br> Remark: if an image is used several times, only one copy is embedded in the file. <h2>Parameters</h2> <dl class="param"> <dt><code>file</code></dt> <dd> Path or URL of the image. </dd> <dt><code>x</code></dt> <dd> Abscissa of the upper-left corner. If not specified or equal to <code>null</code>, the current abscissa is used. </dd> <dt><code>y</code></dt> <dd> Ordinate of the upper-left corner. If not specified or equal to <code>null</code>, the current ordinate is used; moreover, a page break is triggered first if necessary (in case automatic page breaking is enabled) and, after the call, the current ordinate is moved to the bottom of the image. </dd> <dt><code>w</code></dt> <dd> Width of the image in the page. There are three cases: <ul> <li>If the value is positive, it represents the width in user unit</li> <li>If the value is negative, the absolute value represents the horizontal resolution in dpi</li> <li>If the value is not specified or equal to zero, it is automatically calculated</li> </ul> </dd> <dt><code>h</code></dt> <dd> Height of the image in the page. There are three cases: <ul> <li>If the value is positive, it represents the height in user unit</li> <li>If the value is negative, the absolute value represents the vertical resolution in dpi</li> <li>If the value is not specified or equal to zero, it is automatically calculated</li> </ul> </dd> <dt><code>type</code></dt> <dd> Image format. Possible values are (case insensitive): <code>JPG</code>, <code>JPEG</code>, <code>PNG</code> and <code>GIF</code>. If not specified, the type is inferred from the file extension. </dd> <dt><code>link</code></dt> <dd> URL or identifier returned by AddLink(). </dd> </dl> <h2>Example</h2> <div class="doc-source"> <pre><code>// Insert a logo in the top-left corner at 300 dpi $pdf->Image('logo.png',10,10,-300); // Insert a dynamic image from a URL $pdf->Image('http://chart.googleapis.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World',60,30,90,0,'PNG');</code></pre> </div> <h2>See also</h2> <a href="addlink.htm">AddLink</a> <hr style="margin-top:1.5em"> <div style="text-align:center"><a href="index.htm">Index</a></div> </body> </html>
