Hi,
I’m about to publish app for iOs and later for Android.
I use 2 fullscreen pictures in app to show Intro page with some instructions and than info page anytime user needs recalls it.
I have both done as GUI elements and pics are used as fullscreen backround.
Both are retina quality pics png and have size about 200k each. When I import it it has 2 Megs as GUI texture using compressed (which seems to me not being applied). Only way to make is smaller in size I can do to change it to type texture. than it is probably compressed but scaled up to 1024px square which seems to me quite strange to do if i want to show it as GUI pic. And still it has about 700kb.
Is there anything I can do about it? it’s quite bad to have app size up by 1.5 Meg just because of 2 pics.
Nope, there’s no way around it. High resolution full screen images are always going to be like that. This is one of the reasons why you see a lot of mobile games creating a scene based menu around assets that already exist in their games. Not only is it more attractive to see an animated menu on mobile devices, it is also recycling stuff instead of using a huge high res picture.
