What I Did

I've made some simple PSD file using photoshop CS6 which has locked backgroud layer and one pasted png image, and empty layer which has nothing(just typed Shift+Ctrl+N and Enter). On photoshop, those are looks like below.

• layer 1
• background copy
• background (locked)

before nested_layers_to_psd(), pprint_layers() says that

< hello (10, 0, None, None) > - image layer just added
< Layer 1 (0, 0, 0, 0) > - totally empty layer, fully transparent.
< Background copy (50, 107, 290, 347) > - original psd has 240*240 png image on transparent layer
< Background (0, 0, 340, 454) >

layer tree on photoshop.

• hello
• background copy
• background (UNLOCKED)

Working well then I expected, but these minor issues exist. one empty layer disappeared, and background layer unlocked.

Additionally, above stacked.psd's file size changed after saving using photoshop. There might be some un-written-part.
