使用 python 将 tif 文件转换为 pdf

Question

Hi I have a folder with multiple.tif files that I'm trying to convert to individual pdf's. I'm trying to use python as they are more than 3000. I was able to convert a single one but when implementing a code I found for multiples is giving me an error "No such file or directory:" This is the code I'm using, thanks in advance.

from PIL import Image 
import os
directory = r'/Users/reynierDesktop/Drive/' 
for filename in os.listdir(directory): 
    if filename.endswith(".tif"): 
        prefix = filename.split(".tif")[0]
        im = Image.open(filename)
        im.save(prefix+'.pdf')  
    else: 
        continue

I was able to find something and it kind of works. It converts the tif files to pdf, but if the tiff files has more than 1 page it only converts the first one. Any idea how to go around this? Thanks.

from PIL import Image
import os

def makePdf(imageDir, SaveToDir):
    os.chdir(imageDir)
    for j in os.listdir(os.getcwd()):
           os.chdir(imageDir)
           fname, fext= os.path.splitext(j)
           newfilename = fname + ".pdf"
           im = Image.open(fname + fext)
           os.chdir(SaveToDir)
           im.save(newfilename, "PDF", resolution = 100.0)


imageDir = r'my directory path'
SaveToDir = r'where to save them'
makePdf(imageDir, SaveToDir)

jonathan, your directory may be /Users/reynierDesktop/Drive/ but your filename is only something.tif (you can see this if you print out the filename)

so when you Image.open(filename), you are looking for something.tif not /Users/reynierDesktop/Drive/something.tif

so one way around that would be to concat the directory with the filename when using Image.open or you could cd into /Users/reynierDesktop/Drive/ first and then just the filename will be found because you are in the correct directory.
