can not crop thumbnail of passed size - php

Question

I have an image whose size is "300X367" .
I have an image function which crop thumbnail by using this type
but this function crop thumbnail of "41X50". I think it crop thumbnail by scale of original image.
But I want accurate thumbnail size of passing parameter. I can't put code here of image.php as the size is too big.
If anyone have solution for passing size parameter in image tag & crop thumbnail. please tell me.

Try this example code
<?php
function getFileExtenction($image)
{
$imageAry = explode(".", $image);
return $imageAry[1];
}
$image = 'images/imageName.png'; //Your image location
$imageType = getFileExtenction($image); //check the image file type
if ($imageType == "png")
$src = imagecreatefrompng($image);
else if ($imageType == "jpg")
$src = imagecreatefromjpeg($image);
else if ($imageType == "gif")
$src = imagecreatefromgif($image);
else
{
}
list($width, $height) = getimagesize($image); //To get the image width and height
$newwidth = 41; //Give your thumbanail image width
$newheight = 50; //Give your thubnail image height
$tmp = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($tmp, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
$filename = "NewImagename." . $imageType;
/*========== if you want to store this file in a folder Ex: "thumbs" ==========
$filename = "thumbs/NewImagename." . $imageType;
*/
imagejpeg($tmp, $filename, 100);
imagedestroy($src);
imagedestroy($tmp);
?>
