    $targ_w = $targ_h = 150; //保存的图片的大小
    $jpeg_quality = 90;
    $src = '/image/abc.jpg';
    $img_r = imagecreatefromjpeg($src);
    $dst_r = ImageCreateTrueColor( $targ_w, $targ_h );
    imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
    $targ_w,$targ_h,$_POST['w'],$_POST['h']);
    header('Content-type: image/jpeg');
    imagejpeg($dst_r,null,$jpeg_quality);
    ImageDestroy($dst_r);

Copy after login

现在图片可以正常显示了
1:但是如何自动保存在服务器abc123.jpg
2:要想再保存个50*50的缩略图怎么做abc123456.jpg


------解决方案--------------------
不输出,保存为文件,只需修改 imagejpeg()的第二个参数为文件名,那么自然也不需要 Header()声明输出流。
保存缩略图,参见 imagecopyresampled() 函数
------解决方案--------------------
1,
bool imagejpeg ( resource $image [, string $filename [, int $quality ]] )
第二个参数指定文件。

2,
bool imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )

C++ program to convert double type variable to int type C++ program to convert double type variable to int type Aug 25, 2023 pm 08:25 PM

In C++, variables of type int can only hold positive or negative integer values; they cannot hold decimal values. There are float and double values ​​available for this purpose. The double data type was created to store decimals up to seven digits after the decimal point. Conversion of an integer to a double data type can be done automatically by the compiler (called an "implicit" conversion), or it can be explicitly requested by the programmer from the compiler (called an "explicit" conversion). In the following sections, we'll cover various conversion methods. Implicit conversions The compiler performs implicit type conversions automatically. To achieve this, two variables are required - one of floating point type and the other of integer type. When we simply assign a floating point value or variable to an integer variable, the compiler takes care of all the other things
