透過指令轉換krita檔案格式

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

krita 指令使用範例:

/Applications/krita.app/Contents/MacOS/krita 挖.png --export --export-filename 挖.kra

說明:把「挖.png」轉換成「挖.kra」


krita 指令詳細用法:

Usage: /Applications/krita.app/Contents/MacOS/krita [options] [file(s)]

Options:
  -v, --version                                Displays version information.
