We have an issue with some TIFF images that we can't display with a normal Windows image viewer.

For some reason the image is malformed or unstructured.

Tiffinfo returns values that appear normal however (tags, etc.).

The output of tiffinfo would be quite useful in order to understand your image.

Is there any way to know if an image is all right from a display standpoint using some libtiff utility?

You could use 'tiffcp' to convert it to another TIFF file and check if the program returns an error or not.

Also, is there some way to know if an image all white, or all black, using some libtiff utility?

Not that I am aware of.
