How to maintain text clarity of image while zooming?

StackOverflow https://stackoverflow.com/questions/12279044

Domanda

I am developing an app for a magazine and simultaneously I am creating images for those magazines using photo shop.

But, when I zoom these images, the text quality is getting loosed. I have referred to other iPad magazines like India Today. In that, even though I zoom to maximum extent, text quality is too good.

how is that possible? My each image size is almost 800 KB. Even then, when I zoom, I loose the clarity of image. How to maintain the quality of text even when I zoom?

Is that something to do with photoshop editing or coding?

Because you are using raster graphics you are in a losing battle of file size vs. zoom quality. Text is natively vector and scales beautifully as you zoom, so you are much better off rendering text as text rather than generating text as an image in Photoshop. There are many ways to accomplish this, one being to have the image be a background layer and the text be a UILabel above the image.
