"""
|
||||
ppl2psd.py — Convert Photo Editor (dev.macgyver, com.iudesk.android.photo.editor)
|
||||
multi-layer project files (.ppl) to Adobe Photoshop PSD.
|
||||
|
||||
.ppl is a ZIP archive containing:
|
||||
- layers.ini : INI-style description of every layer (bitmap/shape/text)
|
||||
- *.img : layer bitmaps as PNG (referenced via uri=@name.img)
|
||||
|
||||
The converter rasterizes every layer (bitmaps, gradient rounded-rect shapes,
|
||||
text rendered with the original custom fonts when available), then writes a
|
||||
valid PSD with one independent layer per project layer, preserving order,
|
||||
position, opacity, visibility and blend mode.
|
||||
|
||||
Usage:
|
||||
python ppl2psd.py input.ppl [-o output.psd] [--preview preview.png]
