ฉันอัปเดตสคริปต์เพื่อใช้ BackgroundLayer หลักของเอกสาร เพื่อให้ jpg แต่ละตัวที่ส่งออกนั้นถูกคอมไพล์ด้วย
คงจะดีมากถ้ามีคนเพิ่มแท็กลงในเลเยอร์เพื่อทำให้พวกเขาเป็นเลเยอร์หลักแทนการใช้ BackgroundLayer ;-)
สคริปต์แบบเต็ม:
// 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
