[Resolved] How do I set only the thumbnail's width??

[mband2000]

I've finally got my upload script to create images, add water marks to them... create seperate thumbs and add picture info to the database.... BUT ... I've come to one speed bump.

I've found there's no why in my script that I can leave the height of the thumbnail size blank... The reason I want the height blank is because, if I upload a file long in height.. it will looked squished when the thumbnail is mabe because the set WxH is 115x80

Here is my function code... what should I change?

In the function code below $dest_y .. defines the height... and $dest_x .. defines the width.

<? 

function resizeImage($sSourcefile, $dest_y, $dest_x, $sTargetfile, $jpegqual, $gd) { 
global $img;
global $logged_in_user;

            if(!(is_readable($sSourcefile))) { 
                printf("<br /><script language=javascript>alert('Temporary file doesn't exist.');</script><br />");} 
            else { 

                touch($sTargetfile); 
                chmod ($sTargetfile, 0755); 

                if(!(is_writable($sTargetfile))) { 
                    printf("<br /><script language=javascript>alert('No write-permission to new file.');</script><br />");} 

                else { 

                        $img_src_size=getimagesize($sSourcefile); 

                        $img_src=imagecreatefromjpeg($sSourcefile);   

                        $img_dst=($gd < 2 ? imagecreate($dest_x,$dest_y) : imagecreatetruecolor($dest_x,$dest_y));// Choose the proper command depending on the gd-lib version 
                        $gd < 2 ? imagecopyresized($img_dst, $img_src, 0, 0, 0, 0, $dest_x, $dest_y, $img_src_size[0], $img_src_size[1]) : imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, $dest_x, $dest_y, $img_src_size[0], $img_src_size[1]); 
                        imagejpeg($img_dst, $sTargetfile, $jpegqual); 
                        imagedestroy($img_dst); 
                        imagedestroy($img_src); 

                        if(!(file_exists($sTargetfile))) { 
                            return false; } 
                        else { 
                            return true; } 
                } 
            } 
    }
?>

I hope this helps you.

Could you not use an include file?

<?php
define ("HEIGHT",60);
define ("WIDTH",60);
?>

You could then include the .inc file at the top of your script.

eg include("size.inc");

Hope this helps you.

thanks for the reply... but the thing is... I don't want to define the height.. I want the height to be proportionate to the original file deminsions when I reduce the width.

I don't think I'm making sense...🙁

for example....

If the original image is 500 x 400 and I set the width to 100 .... then the height should automatically become 80. So the final thumbnail will be 100x80 .. and deminsions will be proportionate.

Am I still not making sense?? .... :queasy:

Oh... I finally resolved the problem... I just did an indept search again on HotScripts.com and came upon this code.... works like a charm.

If anyone else is running into this problem.. here is the code:

<?php 
function thumbnail($i,$nw,$p,$nn) { 
    $img=imagecreatefromjpeg("$i"); 
    $ow=imagesx($img); 
    $oh=imagesy($img); 
    $scale=$nw/$ow; 
    $nh=ceil($oh*$scale); 
    $newimg=imagecreatetruecolor($nw,$nh); 
    imagecopyresized($newimg,$img,0,0,0,0,$nw,$nh,$ow,$oh); 
    imagejpeg($newimg, $p.$nn); 
    return true; 
} 

#thumbnail(filetouse,newwidth,newpath,newname); 
?>
