Sprite Sheet memory consumption

Solar2D General Questions/Discussion

Hello,

I am using sprite sheets with an alpha channel in my latest project. I am using Texture Packer to create the sprite sheets.
I was wondering if it matters if the source images have a transparent background which is larger than needed?
My tests regarding the memory consumption make me think that corona is smart enough to only render the parts of my sprites in memory which are not 100% transparent. So it doesn’t matter if you don’t carefully crop your image sequence before creating the sprite sheet.
Could someone please confirm this?

you still have to load the whole spritesheet .png file into memory to cut the parts out, so you should reduce the dead space where possible [import]uid: 6645 topic_id: 6104 reply_id: 20889[/import]

Texture Packer takes care of this. [import]uid: 4589 topic_id: 6104 reply_id: 20891[/import]
