使用pytesseract从类型为'PIL.PpmImagePlugin.PpmImageFile'的图像中提取文本时出现错误

Question

trying to extract text from image whose type is 'PIL.PpmImagePlugin.PpmImageFile' using pytesseract . The code and the error is as below

from pdf2image import convert_from_path
pages = convert_from_path('D:/pdf_csv/HealthCare/eRDS - ML/eRDS - ML/2001468/2001468,69,70.pdf',poppler_path='C:/Users/Hp/poppler-0.68.0/bin')
text = pyt.image_to_string(Image.open(pages[0]), lang='eng')

Error I am getting:

AttributeError: 'PpmImageFile' object has no attribute 'read'

Or Is there any method to convert the PpmImageFile to 'jpg' or 'png' format

Answer 1

Add fmt='jpeg' or fmt='png' to your function call to get non-PPM images from pdf2image.

In you example, change

pages = convert_from_path('D:/pdf_csv/Health....001468,69,70.pdf',poppler_path='C:/Users/Hp/poppler-0.68.0/bin')

to

pages = convert_from_path('D:/pdf_csv/Health...001468,69,70.pdf', fmt='jpeg', poppler_path='C:/Users/Hp/poppler-0.68.0/bin')
