有些重覆性的操作，使用手動操作實在很花時間，最好可以透過指令的方式，有機會可以因此自動化處理，以提升效率。指令行的操作語法：
krita importfilename --export --export-filename exportfilename
實際測試，效率太差，每一個圖片檔案都要處理很久，較佳的解法是改手 .psd 格式，可以使用 ImageMagick CLI 程式來轉換，操作語法：
Usage: magick tool [ {option} | {image} … ] {output_image}
Usage: magick [ {option} | {image} … ] {output_image}
magick [ {option} | {image} … ] -script {filename} [ {script_args} …]
magick -help | -version | -usage | -list {option}
Convert single PSD to PNG or JPG
If your file name is psd-file.psd then you need to specify the name along with a [0] as shown below to export the PSD into image. If you don’t add [0] to the file name, all the objects and layers will get exported. To specify the output format, simply use the right extension in the output file name as shown below
$ magick 'psd-file[0].psd' png-file.png $ magick 'psd-file[0].psd' jpg-file.jpg
Batch convert PSD to PNG or JPG
To batch convert a set of PSD files, you can use an ‘*’ to match all the PSD files in the current directory. Additionally, specify ‘%03d’ to the output file name to generate out files in numbered fashion such as out-file-001.png, out-file-002.png, out-file-003.png and so on.
$ magick '*[0].psd' out-file-%03d.png
