私は、私はいくつかのサイズにこの画像をトリミングしたい
この画像をトリミングするには?
、このイメージを持っているため、私はこれが
function thumbanail_for_image($Id, $newfilename, $size=NULL) {
$file_extension = substr($newfilename, strrpos($newfilename, '.') + 1);
$arr = explode('.', $newfilename);
$thumb1 = LOCAL_FOLDER . $arr[0] . "_" . $Id . "." . $file_extension;
$thumb2 = LOCAL_FOLDER . $arr[0] . "_" . $Id . "b" . "." . $file_extension;
$old = LOCAL_FOLDER . $newfilename;
$newfilename = LOCAL_FOLDER . $newfilename;
$srcImage = "";
$sizee = getimagesize($newfilename);
switch ($sizee['mime']) {
case "image/jpeg" :
$srcImage = imagecreatefromjpeg($old);
break;
case "image/png":
$srcImage = imagecreatefrompng($old);
break;
case "image/gif":
$srcImage = imagecreatefromgif($old);
break;
}
$srcwidth = $sizee[0];
$srcheight = $sizee[1];
if ($srcwidth > $srcheight || $srcwidth < $srcheight) {
$destwidth1 = 65;
$rat = $destwidth1/$srcwidth;
$destheight1 = (int) ($srcheight * $rat);
}
elseif ($srcwidth == $srcheight) {
$destwidth1 = 65;
$destheight1 = 65;
}
if ($srcwidth > $srcheight || $srcwidth < $srcheight) {
$destwidth2 = 300;
$rat = $destwidth2/$srcwidth;
$destheight2 = (int) ($srcheight * $rat);
}
elseif ($srcwidth == $srcheight) {
$destwidth2 = 300;
$destheight2 = 300;
}
$destImage1 = imagecreatetruecolor($destwidth1, $destheight1);
$destImage2 = imagecreatetruecolor($destwidth2, $destheight2);
imagecopyresampled($destImage1, $srcImage, 0, 0, 0, 0, $destwidth1, $destheight1, $srcwidth, $srcheight);
imagecopyresampled($destImage2, $srcImage, 0, 0, 0, 0, $destwidth2, $destheight2, $srcwidth, $srcheight);
if ($sizee['mime'] == "image/jpeg") {
imagejpeg($destImage1, $thumb1, 80);
imagejpeg($destImage2, $thumb2, 80);
} elseif ($sizee['mime'] == "image/png") {
imagepng($destImage1, $thumb1, 80);
imagepng($destImage2, $thumb2, 80);
} elseif ($sizee['mime'] == "image/gif") {
imagegif($destImage1, $thumb1, 80);
imagegif($destImage2, $thumb2, 80);
}
imagedestroy($destImage1);
imagedestroy($destImage2);
chmod($destImage1, 0777);
chmod($destImage2, 0777);
return $destImage1;
}
LOCAL_FOLDERを機能 - 使用ローカルへの可変パスです
私が見た問題は、私は$ _FILESを印刷するとき、それについての情報が
[type] =>image/jpeg
を示し、私はgetimagesize()関数を印刷するとき、それは
[mime] => image/png
を印刷している、 感謝
