Code to merge images using php shell command

Copy the code The code is as follows:

#!/usr/local/bin/php -q
author:freemouse
// The following is the description.
print ("This program is used for merging 2 640x480 size .n");
print ("Picture and convert it into a 400x300 size .n");
print ("Need to specify to store the pre-synthesis picture (a.jpg, b.jpg) The default directory n");
print ("The generated image will be saved as c.jpgn");
//Default directory, edit it yourself^_^
$d="/home/freemouse/Desktop";
print ("The current directory is: $dn");
print (" Image a.jpg offset, 0-100: ");
$fp = fopen("php://stdin", "r");
$a = fgets($fp,255);
print (" Image b.jpg offset, 0-100: ");
$b = fgets($fp,255);
fclose($fp);
$ a=$a*3.2;
$a=floor($a);
$b=$b*3.2;
$b=floor($b);
// Scale the two images to 640x480 size
exec( "Scale to 640x480 - quality 95 " . $d . "/a.jpg");
exec("Scale to 640x480 - quality 95 " . $d . "/b.jpg");
$aa = "Convert- Quality 90 - Size 320x480+";
$ab = " " . $d . "/a.jpg";
$bb = " " . $d . "/b.jpg";
$ac = " " . $d . "/aa.jpg";
$cc = " " . $d . "/bb.jpg";
// Save the scaled a.jpg as aa.jpg
$yy = $aa . $a . $ ab . $ac;
print ("$yyn");
exec($yy);
// Save the scaled b.jpg as bb.jpg
$zz = $aa . $b . $bb . $cc ;
print ("$zzn");
exec($zz);
// Merge two pictures into c.jpg.
$adjoin = "Synthesis-quality 80 ";
$adjoin .= $d . "/ aa.jpg ";
$adjoin .= $d . "/bb.jpg ";
$adjoin .= $d . "/c.jpg";
print ("$adjoinn");
exec($adjoin) ;
//Resize c.jpg to 400x300 and add borders.
$edge="Scale to 400x300 -quality 75 -raise 4x4 -sharpen 1x1 " . $d . "/c.jpg";
print ("$edgen ");
exec($edge);
?>

The above has introduced the code for using the php shell command to merge images, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
