@ImagePNG($image,"file.png");

[Jamesm]

I am trying to write a dynamic png image to disk on a shared freeBSD server running Apache.

umask();
@ImagePNG($image,"file.png");

I am guessing I need the umask() to change the file permissions. I have tried 0777 and 077 but still cant write.

Another way to the same end would involve

ImagePNG($image)

which writes to the screen from memory but this lies within a function in an include and I am not able to pass it as a variable and redisplay it..

ob_start();
ImagePNG($image);
$image_data = ob_get_contents();
ob_end_clean();
return $image_data;

How do I redisplay it.

Tried these!!
echo "<div class='box'><img src='$image_data'></div>";

or echo “$image_data”;

Thanks

James

What exactly are you trying to do? It seems a bit fuzzy.

Sounds silly but is a common mistake, have u set the permissions of the directory the images are created in to 777?

Yes I am an idiot!
umask(077) now allows me to write.

As an aside I also had a cache problem and read many complicated solutions but this works fine:
<div class='box'><img src='directory/file.png?".date("Gis")."'></div>

You can put anything after the ? , it just looks like a different file, so I used an hrs mins secs and the newly generated file is called but not from cache.
