To convert pdf files to images, we can use pymupdf library to do it. Here is an tutorial showing how to convert.
However, this way only can convert a pdf page to a small image. For example: here is a pdf file, which size is 8.50 * 11.00 in. PyMuPDF will convert pdf page to png with 612 * 792 pixel defautly.
If you want to convert pdf page to 1224 * 1584, which is 2 times than defaulty. How to do?
Load pdf file
import sys, fitz doc = None file =r'F:\1.pdf' try: doc = fitz.open(file) except Exception as e: print(e) if doc: doc.close() exit(0)
Get the first pdf page
first_page = doc
Set the pdf matrix with given scale
image_matrix = fitz.Matrix(fitz.Identity) image_matrix.preScale(2, 2)
(2, 2) means the size of page is 2 times in width and height. You also can set the value to be (2.5, 2.5) or others
Convert pdf page to image
pix = first_page.getPixmap(alpha = False, matrix=image_matrix) pix.writePNG('demo2.png')
Then you will get an image with 1224 * 1584.
