I have scanned some images on my Win98 PC and they are fine. I have just built a WinXP and the scanned images were written to CD and loaded in the X PC. They too were OK.
I installed my scanner on The XP machine and the installation was faulty, I was warned from the Visioneer [My Scanner] site that the software may not work on XP and that I should first create a System Restore Point which I did. I did not work correctly so I uninstalled it but there was no trace of the restore point that I had created.
Now I find that all my graphic as viewed in PhotoShop 6 and PaintShop Pro show that the aspect ratios have been reversed. An image which on the 98 PC has a print size of 5.063" x 3.487" is 3.487" x 5.063" on the XP PC. (They are too tall or too wide] I can re size them of course but it is not the solution and I have a large number of images.
I have saved the TIF image to JPG on a floppy and transferred it to the XP machine and the results where as above. Any ideas?
