PHP Thumbnail Creation

Posted on 16th Feb 2014 07:03 pm by admin

Ok so i use this function to create thumbnails:

Code: function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode('.',$name);
$src_img=imagecreatefrompng($name);
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y)
{
$thumb_w=$old_x*($new_w/$old_y);
$thumb_h=$new_h;
}
if ($old_x == $old_y)
{
$thumb_w=$new_w;
$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);
if (preg_match("/png/",$system[1]))
{
imagepng($dst_img,$filename);
} else {
imagejpeg($dst_img,$filename);
}
imagedestroy($dst_img);
imagedestroy($src_img);
}
It works and all, but the problem is that for my gallery i need all the pictures to be exactly 150x150, but i also need the images to keep their aspect ratio (so they don't look ugly) so i was thinking i could add like borders that would fill up the space. Ok imagine the function resizes the image to 100x150 so i make the image centered and add 50px wide white black borders on each side of the picture, so it isn't stretched out (keeps it's ratio) and is also 150x150.

The question is, how do i do this?
