can you help...i will be sending a picture via email i can only scan at 8 x 10 the recipient needs to print at 12 x 10 how can i do this so when they enlarge the image comes out proportionate
The recipient will need to use the print option "print to fit" or "scale to paper size". It will not be perfect as they are having to artificially enlarge the picture to fit the paper and so it may come out a little "blocky".
a4 is about 8.5x12 (8.57 x 12.12)
so it's not going to work on any level
the only way to maintain the aspect ratio is to overblow the image and then crop it
portrait to portrait 8x10 enlarges to 10x12.5
(on a4 9.7x12.13)
portrait to landscape is 12x15
(on a4 12.1x15.13)
