I searched this topic in the forum and there's a few hits, but they're old and I don't really get them. I have a few pictures I took with my digital camera and I want to print them and put them in a frame that is 11.5cm * 7.7cm. So, I need to adjust their size to print them that size. I don't have a colour printer, so I'm printing off a library computer in colour, so I can't print them directly off my mac. I'm going to need to transfer them on a usb and open them in windows on a library computer. The pictures are in .JPG format since I uploaded them. -So I went to Preview (program) and Tools > Adjust size. -I typed in 7.7cm for width and it gave me a locked length of 11.1cm as that would probably keep the pictures proportionate. I'm alright with that. But then, when I look at my picture, it's much smaller that the actual dimensions of 7.7cm. Then when I zoom in, it is pixelated. That'd odd because I'm actually reducing the dimensions of my picture. How do I adjust their size so they print to 11.1 cm * 7.7 cm?
