利用Python 將 PDF 單頁轉 JPG

步驟:

1.需要安裝ImageMagick

2.安裝Ghostscript (GS)

3.安裝Wand

開始實現:

1.安裝ImageMagick (由於brew預設7.x會有問題，所以強制安裝6.x)

brew install imagemagick@6

2.連結6.x版本

 brew link imagemagick@6 --force

3.設定export環境變數

 echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.bash_profile

4.安裝GS與wand

 brew install gs

pip3 install wand

5.撰寫&執行

from wand.image import Image

filename = "./檔案名稱.pdf"

def convert_pdf_to_jpg(filename):
    with Image(filename=filename) as img :
        print('pages = ', len(img.sequence))

        with img.convert('jpeg') as converted:
            converted.save(filename='./page.jpeg') //轉出格式名稱
convert_pdf_to_jpg("./檔案名稱.pdf")
