Tôi đã cập nhật tập lệnh để sử dụng BackgroundLayer cốt lõi của tài liệu. Vì vậy, mỗi jpg mà xuất khẩu được biên dịch với nó.
Sẽ thật tuyệt nếu ai đó thêm gắn thẻ vào các lớp để biến chúng thành các lớp Master thay vì BackgroundLayer mặc định ;-)
kịch bản đầy đủ:
// NAME:
// SaveLayers
// DESCRIPTION:
// Saves each layer in the active document to a PNG or JPG file named after the layer.
// These files will be created in the current document folder (same as working PSD).
// REQUIRES:
// Adobe Photoshop CS2 or higher
//Most current version always available at: https://github.com/jwa107/Photoshop-Export-Layers-as-Images
// enable double-clicking from Finder/Explorer (CS2 and higher)
#target photoshop
