一段圖片處理代碼PHP代碼轉C#代碼

把下面代碼轉換成?C#代碼

$res?=?json_decode(stripslashes($_POST['jsondata']),?true);

/*?get?data?*/

$count_images?=?count($res['images']);

/*?the?background?image?is?the?first?one?*/

$background?=?$res['images'][0]['src'];

$photo1?=?imagecreatefromjpeg($background);

$foto1W?=?imagesx($photo1);

$foto1H?=?imagesy($photo1);

$photoFrameW?=?$res['images'][0]['width'];

$photoFrameH?=?$res['images'][0]['height'];

$photoFrame?=?imagecreatetruecolor($photoFrameW,$photoFrameH);

imagecopyresampled($photoFrame,?$photo1,?0,?0,?0,?0,?$photoFrameW,?$photoFrameH,?$foto1W,?$foto1H);

/*?the?other?images?*/

for($i?=?1;?$i?

$insert?=?$res['images'][$i]['src'];

$photoFrame2Rotation?=?(180-$res['images'][$i]['rotation'])?+?180;

$photo2?=?imagecreatefrompng($insert);

$foto2W?=?imagesx($photo2);

$foto2H?=?imagesy($photo2);

$photoFrame2W=?$res['images'][$i]['width'];

$photoFrame2H?=?$res['images'][$i]['height'];

$photoFrame2TOP?=?$res['images'][$i]['top'];

$photoFrame2LEFT=?$res['images'][$i]['left'];

$photoFrame2?=?imagecreatetruecolor($photoFrame2W,$photoFrame2H);

$trans_colour?=?imagecolorallocatealpha($photoFrame2,?0,?0,?0,?127);

imagefill($photoFrame2,?0,?0,?$trans_colour);

imagecopyresampled($photoFrame2,?$photo2,?0,?0,?0,?0,?$photoFrame2W,?$photoFrame2H,?$foto2W,?$foto2H);

$photoFrame2?=?imagerotate($photoFrame2,$photoFrame2Rotation,?-1,0);

/*after?rotating?calculate?the?difference?of?new?height/width?with?the?one?before*/

$extraTop=(imagesy($photoFrame2)-$photoFrame2H)/2;

$extraLeft=(imagesx($photoFrame2)-$photoFrame2W)/2;

imagecopy($photoFrame,?$photoFrame2,$photoFrame2LEFT-$extraLeft,?$photoFrame2TOP-$extraTop,?0,?0,?imagesx($photoFrame2),?imagesy($photoFrame2));

}

//?Set?the?content?type?header?-?in?this?case?image/jpeg

header('Content-type:?image/jpeg');

imagejpeg($photoFrame,?$targetfile);

imagedestroy($photoFrame);

------解決方案--------------------

//使用圖片為水印

public?static?string?ReSizePhoto(string?filePath,?string?LogoPath,?int?width,?int?height)

{

string?fileName?=?System.IO.Path.GetFileName(filePath).ToLower();

string?fileExtension?=?System.IO.Path.GetExtension(filePath).ToLower();

string?document?=?System.IO.Path.GetDirectoryName(filePath)?+?"\\";

bool?check?=?false;

switch?(fileExtension)

{

case?".jpg":?check?=?true;

break;

case?".gif":?check?=?true;

break;

default:?check?=?false;

break;

}

//圖片按比例縮放算法

if?(check)

{

string?saveName?=?Squirrel.Component.doEncrypt.SMD5(Guid.NewGuid().ToString().Replace("-",?"")).Replace("-",?"").ToLower().Substring(8,?16)?+?fileExtension;

System.Drawing.Image?image?=?System.Drawing.Image.FromFile(filePath);

double?h?=?Convert.ToDouble(image.Height.ToString());

double?w?=?Convert.ToDouble(image.Width.ToString());

double?bl?=?h?/?w;
