If I use this below to write a tiff that started as single strip tiff, there
is no problem. But when I try to write an image that started out
as multiple strips it crashes. Do I "need" to save the image multiple
strips? And if I do, can someone help in the right direction (I have
experimented to try and force multiple strips with a group 4 image, with no
luck).
