i try to make the icons of this theme Blue Matrix for iPhone by ~shoowack on deviantART that they looks like retina. For example the phone icon. But if i change the pixel/inch resolution the icon grows and if i reduce it on 60x60 or 114x114 its stay so big and dont look very sharp.
Changing the DPI of an image does nothing, this only applies to printing the picture on paper. Resizing it bigger will not magically make a sharp, bigger image. You are just doubling up pixels, you can't get new information from what's not there.
1. You don't, and wait for a new version to come out.
2. Make everything you want to be higher resolution from scratch going off the style you want to copy.
ok now i made a icon by my self. 800 x 800, 400dpi, but its still looks pixelized... i put it in my theme... in the oroginal theme with the phote button u have 2 versions the normal name.png and the @2x.png but if in put this ending in the high resulution icon it dont change it :S
EDIT:
i made it
and yes you can change the resolution and it works for the ratina display
