Hello. Thanks for your bug report. I apologize for taking almost two months to respond to you. I try to stay on top of bugs, but this one somehow slipped through the cracks. I will need a sample file to do anything useful with. I'd like to test this with the just released beta of libtiff 4.0.0 and, if it doesn't work with that beta, create a report that I can post to the libtiff maintainers' bug database. I would be able to extract the relevant header information and create a file that doesn't contain any of the original image data. Please reply if you can provide the image. We can be in touch separately from the bug report to deal with exchanging the image. I can give you a place to ftp it to, or you can let me know a private location where I can download it from without posting the details to the bug report. As I said, I will make sure that I don't post the image to any public location where the photographer's rights would be violated. Thanks again for the report. -- Jay Berkenbilt <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
