Hi there
We have an application called Document Viewer that retrieves TIF images off a filesystem for viewing via Internet Explorer. IE opens the TIF image, and calls the default TIF file association to display the image (we're currently using Windows Picture and Fax Viewer). Some of the images are faxed documents, where the orientation of the document is incorrect, so the users need to be able to rotate the document.
This functionality worked fine in IE6, but it seems like MS$ have changed IE7 - the Temporary Internet Files folder is now a hidden system folder. It seems like IE7 is thus opening the TIF's in read-only mode, and thus when users try to rotate the images, the Picture and Fax Viewer cannot then resave the TIF image in it's rotated format. So when you rotate the image the dimensions are all messed up and the image is unreadable. In fact the Picture and Fax Viewer throws an error about the image being in read-only mode:-
Because this image is read-only, the rotated version cannot be saved using the same file name. To save it, click Copy To and give it a new file name.
I've tried installing hotfix 896269 (
http://support.microsoft.com/kb/896269).
If I copy the image out of Temporary Internet Files, and double click to open in Windows Picture and Fax Viewer, I can rotate it fine. The permissions on the actual Temporary Internet Files folder and subfolders is fine - the user i'm using has Full Control and I can create files/edit files without a problem. So it's just when IE7 opens the files that it's a problem.
There are very few free TIF viewers out there that can handle multiple page TIF's, that are free for commercial use. We've look at AlternaTIFF, IrfanView etc but they require licenses for corporate use, and we'd like to try get away with a free one if possible as we have roughly 400 workstations.
Any ideas?
thanks
