  • Imagick::readImageFile()

    (PECL imagick 2.0.0)

    Reads image from open filehandle

    说明

    Imagick::readImageFile(resource $filehandle[,string $fileName= NULL]): bool

    Reads image from open filehandle

    参数

    $filehandle
    $fileName

    返回值

    成功时返回TRUE

    错误/异常

    错误时抛出 ImagickException。

    An example of reading an image file from a URL, using a handle returned by fopen():
    <?php
    $handle = fopen('http://example.com/foo.jpg', 'rb');
    $img = new Imagick();
    $img->readImageFile($handle);
    $img->resizeImage(128, 128, 0, 0);
    $img->writeImage('images/foo.jpg');
    ?>
    
    The second parameter will update the result of getFilename() if set. Otherwise the result of getFilename() will retain its original value, prior to calling readImageFile().
