Python 从图像列表创建 PDF

Create PDF from a list of images

提问by Macabeus

Is there any practical way to create a PDF from a list of images files, using Python?

有没有什么实用的方法可以使用 Python 从图像文件列表中创建 PDF？

In Perl I know that module. With it I can create a PDF in just 3 lines:

在 Perl 中，我知道那个模块。有了它，我只需 3 行就可以创建一个 PDF：

use PDF::FromImage;
...
my $pdf = PDF::FromImage->new;
$pdf->load_images(@allPagesDir);
$pdf->write_file($bookName . '.pdf');

I need to do something very similar to this, but in Python. I know the pyPdfmodule, but I would like something simple.

我需要做一些与此非常相似的事情，但是在 Python 中。我知道pyPdf模块，但我想要一些简单的东西。

If you came through Google, here's the code:

如果你是通过谷歌来的，这里是代码：

from fpdf import FPDF
from PIL import Image
def makePdf(pdfFileName, listPages, dir = ''):
    if (dir):
        dir += "/"

    cover = Image.open(dir + str(listPages[0]) + ".jpg")
    width, height = cover.size

    pdf = FPDF(unit = "pt", format = [width, height])

    for page in listPages:
        pdf.add_page()
        pdf.image(dir + str(page) + ".jpg", 0, 0)

    pdf.output(dir + pdfFileName + ".pdf", "F")

Install FPDF for Python:

为 Python安装FPDF：

pip install fpdf

Now you can use the same logic:

现在您可以使用相同的逻辑：

from fpdf import FPDF
pdf = FPDF()
# imagelist is the list with all image filenames
for image in imagelist:
    pdf.add_page()
    pdf.image(image,x,y,w,h)
pdf.output("yourfile.pdf", "F")

You can find more info at the tutorial pageor the official documentation.

您可以在教程页面或官方文档中找到更多信息。

pgmagickis a GraphicsMagick(Magick++)binding for Python.

pgmagick是GraphicsMagick(Magick++)Python的绑定。

It's is a Python wrapper for for ImageMagick(or GraphicsMagick).

它是ImageMagick（或GraphicsMagick）的 Python 包装器。

import os
from os import listdir
from os.path import isfile, join 
from pgmagick import Image

mypath = "\Images" # path to your Image directory 

for each_file in listdir(mypath):
    if isfile(join(mypath,each_file)):
        image_path = os.path.join(mypath,each_file)
        pdf_path =  os.path.join(mypath,each_file.rsplit('.', 1)[0]+'.pdf')
        img = Image(image_path)
        img.write(pdf_path)

Windows 的 pgmagick iinstallation 说明：

1) Download precompiled binary packages from the Unofficial Windows Binaries for Python Extension Packages(as mentioned in the pgmagick web page) and install it.

1) 从用于 Python 扩展包的非官方 Windows 二进制文件（如 pgmagick 网页中所述）下载预编译的二进制包并安装它。

Note: Try to download correct version corresponding to your python version installed in your machine and whether its 32bit installation or 64bit.

注意：尝试下载与您机器上安装的python版本相对应的正确版本，无论是32位安装还是64位安装。

You can check whether you have 32bit or 64bit python by just typing python at your terminal and press Enter..

您可以通过在终端输入 python 并按 Enter 来检查您是否拥有 32 位或 64 位 python。

How about this??

这个怎么样？？

from fpdf import FPDF
from PIL import Image
import glob
import os


# set here
image_directory = '/path/to/imageDir'
extensions = ('*.jpg','*.png','*.gif') #add your image extentions
# set 0 if you want to fit pdf to image
# unit : pt
margin = 10

imagelist=[]
for ext in extensions:
    imagelist.extend(glob.glob(os.path.join(image_directory,ext)))

for imagePath in imagelist:
    cover = Image.open(imagePath)
    width, height = cover.size

pdf = FPDF(unit="pt", format=[width + 2*margin, height + 2*margin])
pdf.add_page()

pdf.image(imagePath, margin, margin)

destination = os.path.splitext(imagePath)[0]
pdf.output(destination + ".pdf", "F")

Some changes to make a pdf from the dir where the files are

从文件所在的目录制作 pdf 的一些更改

I take the code and made some slight change to make it useable as it is.

我接受了代码并进行了一些细微的更改，以使其可以按原样使用。

from fpdf import FPDF
from PIL import Image
import os # I added this and the code at the end

def makePdf(pdfFileName, listPages, dir=''):
    if (dir):

    cover = Image.open(dir + str(listPages[0]))
    width, height = cover.size

    pdf = FPDF(unit="pt", format=[width, height])

    for page in listPages:
        pdf.add_page()
        pdf.image(dir + str(page), 0, 0)

    pdf.output(dir + pdfFileName + ".pdf", "F")


# this is what I added
x = [f for f in os.listdir() if f.endswith(".jpg")]
y = len(x)

If you use Python 3, you can use the python module img2pdf

如果使用 Python 3，则可以使用 python 模块img2pdf

install it using pip3 install img2pdfand then you can use it in a script using import img2pdf

使用安装它pip3 install img2pdf然后你可以在脚本中使用它import img2pdf

sample code

示例代码

import os
import img2pdf

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert([i for i in os.listdir('path/to/imageDir') if i.endswith(".jpg")]))

I had the same problem, so I created a python function to unite multiple pictures in one pdf. The code (available from my github page, uses reportlab, and is based on answers from the following links:

The best method to convert multiple images to PDF I have tried so far is to use PILpurely. It's quite simple yet powerful:

到目前为止，我尝试过的将多个图像转换为 PDF 的最佳方法是PIL纯粹使用。它非常简单但功能强大：

from PIL import Image

im1 = Image.open("/Users/apple/Desktop/bbd.jpg")
im2 = Image.open("/Users/apple/Desktop/bbd1.jpg")
im3 = Image.open("/Users/apple/Desktop/bbd2.jpg")
im_list = [im2,im3]

pdf1_filename = "/Users/apple/Desktop/bbd1.pdf"

im1.save(pdf1_filename, "PDF" ,resolution=100.0, save_all=True, append_images=im_list)

Just set save_allto Trueand append_imagesto the list of images which you want to add.

只需将和设置save_all为要添加的图像列表。Trueappend_images

You might encounter the AttributeError: 'JpegImageFile' object has no attribute 'encoderinfo'. The solution is here Error while saving multiple JPEGs as a multi-page PDF

您可能会遇到AttributeError: 'JpegImageFile' object has no attribute 'encoderinfo'. 解决方案在这里将多个 JPEG 保存为多页 PDF 时出错

Note:Install the newest PILto make sure save_allargument is available for PDF.

注意：安装最新版本PIL以确保save_all参数可用于 PDF。

**** Convert images files to pdf file.****
from os import listdir
from fpdf import FPDF

path = "/home/bunny/images/" # get the path of images

imagelist = listdir(path) # get list of all images

pdf = FPDF('P','mm','A4') # create an A4-size pdf document 

x,y,w,h = 0,0,200,250

for image in imagelist:

    pdf.add_page()
    pdf.image(path+image,x,y,w,h)

pdf.output("images.pdf","F")

I know the question has been answered but one more way to solve this is using the pillow library. To convert a whole directory of images:

我知道问题已得到解答，但解决此问题的另一种方法是使用枕头库。要转换整个图像目录：

from PIL import Image
import os


def makePdf(imageDir, SaveToDir):
     '''
        imageDir: Directory of your images
        SaveToDir: Location Directory for your pdfs
    '''
    os.chdir(imageDir)
    try:
        for j in os.listdir(os.getcwd()):
            os.chdir(imageDir)
            fname, fext = os.path.splitext(j)
            newfilename = fname + ".pdf"
            im = Image.open(fname + fext)
            if im.mode == "RGBA":
                im = im.convert("RGB")
            os.chdir(SaveToDir)
            if not os.path.exists(newfilename):
                im.save(newfilename, "PDF", resolution=100.0)
    except Exception as e:
        print(e)

imageDir = r'____' # your imagedirectory path
SaveToDir = r'____' # diretory in which you want to save the pdfs
makePdf(imageDir, SaveToDir)

For using it on an single image:

在单个图像上使用它：

From PIL import Image
import os

filename = r"/Desktop/document/dog.png"
im = Image.open(filename)
if im.mode == "RGBA":
    im = im.convert("RGB")
new_filename = r"/Desktop/document/dog.pdf"
if not os.path.exists(new_filename):
    im.save(new_filename,"PDF",resolution=100.0)

It's not a truly new answer, but - when using img2pdf the page size didn't come out right. So here's what I did to use the image size, I hope it finds someone well:

这不是一个真正的新答案，但是 - 使用 img2pdf 时，页面大小不正确。所以这是我使用图像大小所做的工作，我希望它能很好地找到某人：

assuming 1) all images are the same size, 2) placing one image per page, 3) image fills the whole page

假设 1) 所有图像大小相同，2) 每页放置一张图像，3) 图像填满整个页面

from PIL import Image
import img2pdf

with open( 'output.pdf', 'wb' ) as f:
    img = Image.open( '1.jpg' )
    my_layout_fun = img2pdf.get_layout_fun(
        pagesize = ( img2pdf.px_to_pt( img.width, 96 ), img2pdf.px_to_pt( img.height, 96 ) ), # this is where image size is used; 96 is dpi value
        fit = img2pdf.FitMode.into # I didn't have to specify this, but just in case...
    )
    f.write( img2pdf.convert( [ '1.jpg', '2.jpg', '3.jpg' ], layout_fun = my_layout_fun ))
