I am designed a web based document preview module for my system. I have images at the size of about 2000 X 2000 pixels. For user convenience, I put in function to enable them to zoom in and zoom out on the image.
My users complain that when zoom down to 50%, the text on the image becomes unreadable. According to them, when a image is pasted into a MS Word document, and they scale the image down 50%, the text is still readable.
My Question is how to achieved a similar result such as the one on MS Word?
