RE: [Digital BW] QTR(Gui) bug - A3 paper, 720ppi

2005-03-28 by Stephen Billard

Please download the TIFF tag viewer from
http://www.awaresystems.be/imaging/tiff/astifftagviewer.html. 

This software will let you see what the TIFF tags of the image file say.

My guess it that the image does not have a correct RESOLUTIONUNIT value.

Anyway, tell me what the values of:

RESOLUTIONUNIT, IMAGEWIDTH, IMAGELENGTH, XRESOLUTION, and YRESOLUTION are.
