How to enlarge a picture to a specif size
I have tried enlarging an image to measure 20inches by 66. I took the image to Kinkos and they were able to zoom it out which is not what I'm look for. Since, then the image is distorted. They said that they can print it but I have to take them the file in PDF form already enlarged to the size I want it. So, how can I achieve that?
I'm using it to create a stencil in which I'm planning to use it to etch a glass door. If you have any pointers I would be so glad to hear them.
