鉴于JPG图像,在水平方向切断它,使得spic的大小约为100K
任何提示?

过去使用此功能对我来说效果很好......
这将获取一个输入文件并创建指定大小的图块...
function makeTiles($name, $imageFileName, $crop_width, $crop_height)
{
$dir = "source dir";
$slicesDir = "target dir";
// might be good to check if $slicesDir exists etc if not create it.
$inputFile = $dir . $imageFileName;
$img = new Imagick($inputFile);
$imgHeight = $img->getImageHeight();
$imgWidth = $img->getImageWidth();
$cropWidthTimes = ceil($imgWidth/$crop_width);
$cropHeightTimes = ceil($imgHeight/$crop_height);
for($i = 0; $i < $cropWidthTimes; $i++)
{
for($j = 0; $j < $cropHeightTimes; $j++)
{
$img = new Imagick($inputFile);
$x = ($i * $crop_width);
$y = ($j * $crop_height);
$img->cropImage($crop_width, $crop_height, $x, $y);
$data = $img->getImageBlob();
$newFileName = $slicesDir . $name . "_" . $x . "_" . $y . ".jpg";
$result = file_put_contents ($newFileName, $data);
}
}
}
