I'm exporting PSD layers to PNGs for a game's texture atlases.
When I'm doing
Copy -> New File (RGB 8-bit) -> Save As PNG, the resulting PNG is quite heavy and Finder shows white background instead of transparent.
But when I'm using
Export Layers to Files (24-bit PNG), the resulting PNG is 70-95% smaller.
I don't need any compression by Photoshop - my texture creating software can do it well by itself. But I'd like to export layers by script instead of saving them manually.
- What makes
Saved AsPNG that heavy? Do exported images lose any color information or are reduced in quality?
- Why is transparency different?
