[mapserver-users] PHP $imgObj->saveImage(null) sends headers

[Pavel Iacovlev]

Oh sorry, your code is correct thought you used ob_end_clean and you
are using ob_get_clean. But the snippet works for me with out any
phpmapscript modification.

> $image->saveimage('');

> ob_end_clean();
> imagepng($image);
