PHP Imagick queryFormats()用法及代碼示例

Imagick::queryFormats()函數是PHP中的內置函數，用於獲取Imagick支持的格式。

用法:

array Imagick::queryFormats( string $pattern = "*" )

參數：此函數接受單個參數$pattern，該參數保存要與格式匹配的模式。

返回值：此函數返回一個數組，其中包含Imagick支持的格式。

異常：該函數在錯誤時引發ImagickException。

下麵給出的程序說明了PHP中的Imagick::queryFormats()函數：

程序1:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Get all the formats 
$formats =  $imagick->queryFormats('*'); 
print("<pre>".print_r($formats, true)."</pre>"); 
?>
