New iPad Graphics Making App Three Times Larger

Games
#1

I’ve been putting in the new graphics into the current app I’ve been building, and it’s exploded the size from around 30M to upwards of 90+ (probably will end up closer to 120). My basic background image sizes are for the iPad 1 & 2 (1024x768), and now I’m putting in graphics for the New iPad (2048x1536).

I’m just looking for some feedback from the community as to what you all are doing about this.

Do you/can you create separate apps in the app store for standard def and HD?
Or do you just bundle the whole thing, and hope for the best? [import]uid: 115606 topic_id: 23906 reply_id: 323906[/import]

most games went from example " the Bat" to “the Bat HD”
so i would assume that to comply with the NEW iPad you would need to go to RHD? :wink: its a very pertinent question. If size matters then i would create 2 versions.

as for why its going up from 30 - 90
i would assume its because you now have 2 types of images saved within your folder

here is a quick example:
normal img1 = 3mb
@2x img1 = 6 mb
total app => normal + @2x => 9mb

good luck would love to know what you end up choosing.

Hey SoloSebo,

Yes, It turns out that graphics are closer to 4X larger, since you’re doubling both the width and the height.

We’re ending up restructuring the app itself to implement certain graphics more often, but we’re going to be bundling the whole thing. It looks like, even after our restructuring, we’re still going to end up at about 120MB, but it’s going to look good on that Retina display.

If anyone else has any feedback as to what they’re doing, it would be greatly appreciated. [import]uid: 115606 topic_id: 23906 reply_id: 96575[/import]

I found an app called PNGenie that will make PNG files smaller. I had mixed results with it… all of my images shrank with the app but sometimes the resulting PNG didn’t work in Corona.

You could try using this to see how much space it saves you on the larger files. For the ones that don’t work after compressing, just revert to the originals.

Hello,

Did you try “jpeg”? I am not sure how it would look like but for certain large background images it maybe good enough.

Just a suggestion.

Agree with lemsim.
Any images that don’t require transparency, you can use JPG to save a lot of space (way less than half of PNG size).
Use high quality JPG setting and you will not be able to tell the difference from PNG. [import]uid: 39031 topic_id: 23906 reply_id: 96645[/import]

This is probably obvious to most developers, but for those using primarily PNGs, remember to choose the proper color “depth” when you export/save. Graphics applications might specify this differently… Adobe Fireworks uses “PNG 8”, “PNG 24” and “PNG 32” for example. This choice can vastly affect your file sizes. PNG 8, for “flat” images with no transparency, can be less than half the size of the other depths.

For a detailed explanation of the different in PNG color depth, read the Wiki:
