寫這個工具是因為專案上有需要批次輸出圖層檔案
因為Krita 免費，又可以用Python撰寫
花了一些時間找了一些教學
總總約花了半天，寫出這樣的工具。
基本用途:
依開始的圖檔位置，自動建立一個存放輸出圖片的資料夾，並依圖層名層為檔案名稱。
目前每處理一個圖層都要按一次確定，因為管方文件好像有問題無法使用，所以也不確定要如何解決，但比起要手動一張一張輸出圖片，還是要方便跟輕鬆多了吧。
Python code: 下載位置

This tool is to export png per layer with baselayer, and make a folder for store all those exported pics.
It applys the name of the layer as a filename automatically.
Exported folder will be created under where the opened file is.

doc_dir = os.path.dirname( doc.fileName( ))#get the file path

#If folder doesn't exist then create the folder for export pics

#First: Go over all layer turn off it's visible except basic layer.

#Second: Trun on the visible of the layers one by one then exporting it.
