Enlarge image without losing quality?


Recommended Posts

If you're adding pixels, you're going to lose quality. End of story.

The best you can hope for is for minimal impact on the original image. This will be a function of a number of factors:

1. How much the image is enlarged. Bigger enlargement = more pixels need to be 'made up' from the exisiting info.

2. What algorithm is used for the resampling (the 'making up' of the missing pixel data).
