Here is a solution that works with only the standard packages. <code>matplotlib</code> has a PDF backend to save figures to PDF. You can create a figures with subplots, where each subplot is one of your images. You have full freedom to mess with the figure: Adding titles, play with position, etc. Once your figure is done, save to PDF. Each call to <code>savefig</code> will create another page of PDF.

Example below plots 2 images side-by-side, on page 1 and page 2.

<pre><code>from matplotlib.backends.backend_pdf import PdfPages
import matplotlib.pyplot as plt
from scipy.misc import imread
import os
import numpy as np

files = [ "Column0_Line16.jpg", "Column0_Line47.jpg" ]
def plotImage(f):
 folder = "C:/temp/"
 im = imread(os.path.join(folder, f)).astype(np.float32) / 255
 plt.imshow(im)
 a = plt.gca()
 a.get_xaxis().set_visible(False) # We don't need axis ticks
 a.get_yaxis().set_visible(False)

pp = PdfPages("c:/temp/page1.pdf")
plt.subplot(121)
plotImage(files[0])
plt.subplot(122)
plotImage(files[1])
pp.savefig(plt.gcf()) # This generates page 1
pp.savefig(plt.gcf()) # This generates page 2
pp.close()
</code></pre>

PNG, GIF and JPG support (including transparency and alpha channel)

If you are familiar with LaTex you might want to consider <a href="https://jeltef.github.io/PyLaTeX/current/" rel="noreferrer">pylatex</a>

One of the advantages of pylatex is that it is easy to control the image quality. The images in your pdf will be of the same quality as the original images. When using reportlab, I experienced that the images were automatically compressed, and the image quality reduced. 

The disadvantage of pylatex is that, since it is based on LaTex, it can be hard to place images exactly where you want on the page. However, I have found that using the position argument in the Figure class, and sometimes Subfigure, gives good enough results.

Example code for creating a pdf with a single image:

<pre><code>from pylatex import Document, Figure

doc = Document(documentclass="article")
with doc.create(Figure(position='p')) as fig:
fig.add_image('Lenna.png')

doc.generate_pdf('test', compiler='latexmk', compiler_args=["-pdf", "-pdflatex=pdflatex"], clean_tex=True)
</code></pre>

In addition to installing pylatex (pip install pylatex), you need to install LaTex. For Ubuntu and other Debian systems you can run <code>sudo apt-get install texlive-full</code>. If you are using Windows I would recommend <a href="https://miktex.org/howto/download-miktex" rel="noreferrer">MixTex</a>

I use <a href="https://github.com/rst2pdf/rst2pdf" rel="noreferrer">rst2pdf</a> to create a pdf file, since I am more familiar with RST than with HTML. It supports embedding almost any kind of raster or vector images.

It requires <a href="https://www.reportlab.com/" rel="noreferrer">reportlab</a>, but I found reportlab is not so straight forward to use (at least for me).

It depends on what format your image files are in, but for a project here at work I used the tiff2pdf tool in LibTIFF from <a href="http://www.remotesensing.org/libtiff/" rel="nofollow noreferrer">RemoteSensing.org</a>.
Basically just used subprocess to call tiff2pdf.exe with the appropriate argument to read the kind of tiff I had and output the kind of pdf I wanted. If they aren't tiffs you could probably convert them to tiffs using PIL, or maybe find a tool more specific to your image type (or more generic if the images will be diverse) like ReportLab mentioned above.

I'm working on a project which takes some images from user and then creates a PDF file which contains all of these images.

Is there any way or any tool to do this in Python? E.g. to create a PDF file (or eps, ps) from image1 + image 2 + image 3 -> PDF file?

我在一个项目上工作，该项目需要从用户的一些图像，然后创建一个PDF文件，其中包含所有这些图像。在Python中有什么方法或工具可以做到这一点吗？例如，从image1 +图像2+图像3创建一个->文件？
