Thanks for the post but while I am trying to use deskew in R , its throwing
error while installation. But I have a work around which gave somewhat
similar results. The magick package has image_deskew but that didn't seem
to work. The output is generating a '|' and 'CATHODEFULL'. and I am not
sure why. Is there any way out?
Code:
library magick
image=image_read_pdf('https://www.hindustancopper.com/Upload/Reports/0-637189269505122500-AnnualReport.pdf')
text=image %>%
image_rotate(3)%>%
image_ocr()
