<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> |
