ASCII value for tag "Software" does not end in null byte.

[steelcrusher]

Hello!

I am converting .tiff to .png, the conversion works but it always display this message:

"ASCII value for tag "Software" does not end in null byte. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/922."


Thank you.

----More info----
in windows I used:

Code: Select all

convert 00000000.tif 00000000.png

in php I used:

Code: Select all

 
$image = new \Imagick($source.'.tif');
$image->setImageFormat('png');
$image->writeImage($source.'.png');

install latest Imagik on a Centos server and also have a 6.9.4-4 on my windows 10 machine and both display that error

also here is "identify -verbose" of the file
