我已经找到了一个功能,可以将一些图像复制到画布上并将其保存到文件中。我的代码位于帖子的底部。
当我尝试将15张图像复制到画布上时,代码工作正常,但是当我尝试复制30时,它就停止了。没有错误或例外......
我希望你们中的一个可以帮助我:)
$img = imagecreatefromjpeg( $image );
$imgWidth = imagesx($img);
$imgHeight = imagesy($img);
// CREATE CANVAS AND FILL WITH WHITE
$canvas = imagecreatetruecolor( $guidelines['canvasW'] * $dpi, $guidelines['canvasH'] * $dpi );
$color = imagecolorallocate( $canvas, 255, 255, 255 );
imagefill( $canvas, 0, 0, $color );
// COPY THE IMAGES ONTO THE CANVAS
foreach( $guidelines['imageGuide'] as $guide ):
$bestFit = bestFit( $imgWidth, $imgHeight, $guide['W'] * $dpi, $guide['H'] * $dpi );
if( $bestFit['rotate'] ) {
$output = imagerotate($img, 90, 0);
} else {
$output = imagerotate($img, 0, 0);
}
imagecopyresampled($canvas, $output, $guide['X'] * $dpi, $guide['Y'] * $dpi, 0, 0, $bestFit['x'], $bestFit['y'], imagesx($output), imagesy($output));
imagedestroy($output);
endforeach;
$ guidelines是一个数组。这是一个将16个图像复制到画布上的例子
$guidelines = array( 'canvasW' => 20,
'canvasH' => 30,
'imageGuide' => array(
array('W' => 18, 'H' => 13, 'X' => 1, 'Y' => 1.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 1.25, 'Y' => 15),
array('W' => 3.5, 'H' => 4.5, 'X' => 4.75, 'Y' => 15),
array('W' => 3.5, 'H' => 4.5, 'X' => 8.25, 'Y' => 15),
array('W' => 3.5, 'H' => 4.5, 'X' => 11.75, 'Y' => 15),
array('W' => 3.5, 'H' => 4.5, 'X' => 15.25, 'Y' => 15),
array('W' => 3.5, 'H' => 4.5, 'X' => 1.25, 'Y' => 19.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 4.75, 'Y' => 19.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 8.25, 'Y' => 19.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 11.75, 'Y' => 19.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 15.25, 'Y' => 19.5),
array('W' => 3.5, 'H' => 4.5, 'X' => 1.25, 'Y' => 24),
array('W' => 3.5, 'H' => 4.5, 'X' => 4.75, 'Y' => 24),
array('W' => 3.5, 'H' => 4.5, 'X' => 8.25, 'Y' => 24),
array('W' => 3.5, 'H' => 4.5, 'X' => 11.75, 'Y' => 24),
array('W' => 3.5, 'H' => 4.5, 'X' => 15.25, 'Y' => 24),
),
);

我猜你在这份工作中使用了太多内存。 ImageCopyResampled
必须通过这项工作为RAM写很多东西,而且图像会占用大量内存。检查php.ini文件中的memory_limit,尝试增加它,看看是否可以通过写入画布的更多/所有图像。祝你好运!
