Hi All,
I am currently doing a website redesign. I only have 1 problem.
The website has a large gallery inwhich the picures are uploaded and resized
into a thumbnail, medium size and a larger size. All without a watermark.
Now the problem is the medium sized picture. Due to the redesign the area
where the picture is desplayed, the picture doesn't fit :(
I use the following script to display the image :
<?
require("../../dbfuncs.php");
$sql = "SELECT ID, imgname FROM modgalimg WHERE ID='$id'";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_array($result);
$subID=144;
if(!isset($nolog)) logEntry("modgalimg", $id, "imgname");
if(strstr($row['imgname'], ".jpg")) $im =
imagecreatefromjpeg("$datastore/".$row['imgname']);
if(strstr($row['imgname'], ".png")) $im =
imagecreatefrompng("$datastore/".$row['imgname']);
$logo = imagecreatefrompng(dirname($SCRIPT_FILENAME)."/logo.png");
$src_w = ImageSX($im);
$src_h = ImageSY($im);
$can_img = imagecreatetruecolor($src_w, $src_h);
ImageColorTransparent($logo, imagecolorat($logo,0,0));
imagecopy($can_img, $im, 0,0,0,0, $src_w, $src_h);
imagecopymerge($can_img, $logo,
$src_w-ImageSX($logo),$src_h-ImageSY($logo),0,0, ImageSX($logo),
ImageSY($logo),100);
ImageJPEG($can_img,'',100);
imagedestroy($logo);
imagedestroy($im);
imagedestroy($can_img);
?>
Now I need to resize the picture in this script without saving the actual
size. The image which needs to be resized is image stored in the $datastore
directory. ofcourse it needs to be resized in correct proportions.
I have tried different options but I only get black images either with or
without the watermark.
So if anybody can be of any assistance, it will make me a very happy person
;-)
Kind regards,
Willem-Jan
