Resize Problem Any suggestions?

Hey,

i am basically dynamically displaying images onto a page using PHP, the problem is i need them to displayed at a much smaller size and in proportion. here is a snippet of the code.

	
echo '<a href="'. $auction_link .'"><img src=';
echo ((!empty($main_image)) ? 'thumbnail.php?pic=' . $main_image . '&w=' . $layout['hpfeat_width'] . '&sq=Y' : 'themes/' . $setts['default_theme'] . '/img/system/noimg.gif');

echo '" height="80" width="60" border="0" alt="' .$item_details[$counter]['name'] . '"></a><br><br>';

Code (markup):

as you can see at the moment to resize the image i am having to add in the height="80" width="60" which means that some images are totally out of proporotion. can anyone think of a little hack around this?

 

do a simple crop in thumbnail.php to the size 80x60

 

Do you have a snipprt of code to help me?

Oops its simpl
Have a look here http://articles.sitepoint.com/article/image-resizing-php

 

Usually I use this function:

$sSource - file-source
$sDest - file-destination
$iMaxX - max width
$iMaxY - max height
$iRGB - the color of filling
$iQuality - the quality of jpg image, that we get as a result
*/
function SaveResized ($sSource, $sDest, $iMaxX, $iMaxY, $iRGB=0xFFFFFF, $iQuality=80){
  if (!file_exists($sSource)) return -1; //file not found
  $aImgSize = getimagesize($sSource);
  if ($aImgSize === false) return -2; //getimgsize error
  $sMime = strtolower(substr($aImgSize['mime'], strpos($aImgSize['mime'], '/')+1));
  $fcImageCreateFrom = "imagecreatefrom" . $sMime;
  if (!function_exists($fcImageCreateFrom)) return -3;  //unknown format
  $fXRatio = $iMaxX / $aImgSize[0];
  $fYRatio = $iMaxY / $aImgSize[1];
  $fRatio       = min($fXRatio, $fYRatio);
  $fUseRatio = ($fXRatio == $fRatio);
  $iNewWidth   = $fUseRatio  ? $iMaxX  : floor($aImgSize[0] * $fRatio);
  $iNewHeight  = !$fUseRatio ? $iMaxY : floor($aImgSize[1] * $fRatio);
  $iNewLeft    = $fUseRatio  ? 0 : floor(($iMaxX - $iNewWidth) / 2);
  $iNewTop     = !$fUseRatio ? 0 : floor(($iMaxY - $iNewHeight) / 2);
  $rImg = $fcImageCreateFrom($sSource);
  $rImgDest = imagecreatetruecolor($iMaxX, $iMaxY);
  imagefill($rImgDest, 0, 0, $iRGB);
  imagecopyresampled($rImgDest, $rImg, $iNewLeft, $iNewTop, 0, 0,
    $iNewWidth, $iNewHeight, $aImgSize[0], $aImgSize[1]);
  imagejpeg($rImgDest, $sDest, $iQuality);
  imagedestroy($rImg);
  imagedestroy($rImgDest);
  return true;
}

PHP:

 

Oops Post a Finished Sample Code hre!
Else they may confuse RGB with iRGB and others

 

OK. Here is the example of using this function:

  $myfil =$_FILES['photo']['tmp_name'];
  if (is_uploaded_file($myfil)) 
		SaveResized ($myfil, "../images/content/brand_img$id.jpg",89, 30);

PHP:

 

Oops!
I mean this structure

$iRGB - the color of filling
$iQuality - the quality of jpg image, that we get as a result

PHP:

 

i thought you're a programmer, you don't even know how to use that function..

 

Oops!
If i need to solve this is the solution

$iRGB='e8edf0';
$iQuality=80;
