tool to check if TIFF files compressed ?

<< < (2/12) > >>

skwire:
Can you post a few examples of both types of TIFF file?  Maybe there is something in the header that can be read to determine if it's compressed or not.

I have one word for you... clairvoyance.  Other than that, Irfanview's image properties can tell you compression state.

@tomos: maybe you can try this LibTIFF tool - tiffinfo.

tiffinfo
Display information about one or more TIFF files.

thanks all,
I'm only going to get a chance to look at IrfanView this evening - Library stuff looks technical but I've donwloaded and will look at it and see if I can figure it out

this site also has some info about the compression tags for TIFF.

Forgot to say compression is LZW.
I can post a couple of samples later as well
