I have written a script which sample a resized image and create a
copyrightstring on it. Then it should output the result on display. In
most of times its makes wonderfull, but sometimes its output incomplet
or empty images. Its happends every 10 times of try to load an image.
Here is the complete script:
function display_resized_image( $image, $newimage_extension,
$newimage_height,$newimage_width,$quality=80,$tmpimagetype="image/jpeg")
{
$image_size=getimagesize($image);
$image_width=$image_size[0];
$image_height=$image_size[1];
//### get image
$pathexploted=pathinfo($image);
$image_extension=$pathexploted["extension"];
if ($image_extension=="jpg" || $image_extension=="png" ||
$image_extension=="tmp")
{
if ($image_extension=="jpg")
{
$image_extension="jpeg";
}
if ($image_extension=="tmp")
{
$tmptype=explode("/",$tmpimagetype);
if ($tmptype[0]=="image")
{
switch($tmptype[1])
{
case "jpeg":
$image_extension="jpeg";
break;
case "jpg":
$image_extension="jpeg";
break;
case "png":
$image_extension="png";
break;
}
}
else
{
return -11;
}
}
$function="imagecreatefrom" . $image_extension;
$image = $function($image);
}
else
{
return -12;
}
//### calculate new size
if ($newimage_height==-1 && $newimage_width==-1)
{
$newimage_height=$image_height;
$newimage_width=$image_width;
}
else
{
if ($newimage_width==-1)
{
$newimage_width=($image_width*$newimage_height)/$image_height;
}
if ($newimage_height==-1)
{
$newimage_height=($image_height*$newimage_width)/$image_width;
}
}
//### create buffer image and sample resized image
$buffer = imagecreatetruecolor($newimage_width,$newimage_height);
imagecopyresampled($buffer,$image,0,0,0,0,$newimage_width
,$newimage_height,$image_width,$image_height);
if ($newimage_width>=250)
{
//### Copyrightbild erstellen
$cpbuffer = imagecreatetruecolor(300,30);
imagestring ($cpbuffer, 5, 45, 8, "(C)2002 www.shopforkids.de",
imagecolorexact($cpbuffer, 255, 255, 255));
//### alising line
$linebuffer = imagecreatetruecolor(300,2);
//### Copyrightbild einblenden
imagecopymerge($buffer,$cpbuffer,$newimage_width-300,$newimage_height-30,0,0,300,30,40);
imagecopymerge($buffer,$linebuffer,$newimage_width-300,$newimage_height-32,0,0,300,2,20);
}
//### shows images
if ($newimage_extension=="jpg" || $newimage_extension=="png" ||
$newimage_extension=="jpeg")
{
if ($newimage_extension=="jpg")
{
$newimage_extension="jpeg";
}
Header("Content-type: image/" . $newimage_extension);
$function="image" . $newimage_extension;
//$function="imagepng";
if ($function=="imagejpeg")
{
$function($buffer,"",$quality);
}
else
{
$function($buffer);
}
}
else
{
return -21;
}
imagedestroy($buffer);
imagedestroy($cpbuffer);
imagedestroy($linebuffer);
}
Im sorry for my bad english.
