When iOS shrinks an image, does it clip/pixelate it? -

-

i have 2 relatively small pngs images inside uibuttons.

once our app finished, might want resize buttons , make them smaller.

now, can resizing button frame; system automatically re-sizes images smaller.

would system's autoresize cause image ugly after shrinking image? (i.e., clip pixels , make less smooth if shrink in photo editor myself?)

or better make image sizes intended be?

it best make images of correct size beginning. resize-functions have negative impact on end result. if scale larger image big different, if scale down smaller creating visible noise in image. let's have line of 1 pixel in image. scale down 90% of original size, line use 90% of pixel wide , other parts of images influence colors of same pixels.
