[PHP-DB] How to compress a jpeg (qualitysetting) before saving it to the server?

[Andy]

Hi there,

I am uploading jpegs in my app. How can I control the compression setting
before saving?

Currently my code looks like:

########################################################################
  $inputImg = ImageCreateFromJPEG($image);

   # old size
   $srcX = imagesx($inputImg);
   $srcY = imagesy($inputImg);


  if ($same == true){ // Image must have the given size. Empty parts are
filled black.

   # new size
   $ratio = ($srcY / $dstY);
   $dstX = ($srcX / $ratio);

   $outputImg = ImageCreateTrueColor($maxX, $dstY);
   imagefill($outputImg, 0, 0, ImageColorAllocate($outputImg, 0, 0,0));
   imagecopyresampled($outputImg, $inputImg, (($maxX - $dstX) / 2),0,0,0,
$dstX, $dstY, $srcX, $srcY);
  }
  else{ // Image has a y ratio size. Results in not all images same y size.

   # new size
   $ratio = ($srcX / $maxX);
   $dstY = ($srcY / $ratio);

   $outputImg = ImageCreateTrueColor($maxX, $dstY);
   imagefill($outputImg, 0, 0, ImageColorAllocate($outputImg, 0, 0,0));
   imagecopyresampled($outputImg, $inputImg, 0,0,0,0, $maxX, $dstY, $srcX,
$srcY);
  }

  # save file
  imagejpeg($outputImg, $path.$name.".jpg");

########################################################################

Thanx for any help.

Cheers Andy
