在python中将png图像转换为一个pdf [英] png images to one pdf in python
本文介绍了在python中将png图像转换为一个pdf的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个.png图像列表.我需要将它们全部转换为一个pdf，每页9张图像，而不是将它们垂直垂直放置，而是填满所有宽度，然后再继续下一行. 每次的图片数量可以不同(12，... 15)
我尝试过fpdf
from fpdf import FPDF
list_of_images = [1.png, 2.png, ... 15.png]
w = 70
h = 60
pdf = FPDF(orientation = 'L')
for image in list_of_images:
pdf.image(image, w=sizew, h=sizeh)
pdf.output("Memory_usage.pdf", "F")
，还有wkhtmltopdf
template = Template('''<!doctype html>
<html>
<body>
<div style="display: flex; flex-direction: row">
{% for image in images %}
<img src="{{ image }}" />
{% endfor %}
</div>
</body>
</html>''')
list_of_images = [1.png, 2.png, ... 15.png]
html = template.render(images=list_of_pict)
with open("my_new_file.html", "wb") as fh:
fh.write(html)
p = subprocess.Popen(['wkhtmltopdf', '-', 'Memory_usage.pdf'], stdin=subprocess.PIPE, universal_newlines=True)
p.communicate(html)
p.wait()
但他们俩都将每张图片放在另一张图片下
解决方案
只需使用FPDF将每个图像放置在所需的坐标上即可:
pdf.image(image, x=50, y=100, w=sizew, h=sizeh)

I have a list of .png images. I need to convert all of them into one pdf, 9 images per page , but not to place them one after another vertically, but fill in all the width, and only then continue to next row. Amount of pictures can be different each time (12, ... 15)
I have tried fpdf
from fpdf import FPDF
list_of_images = [1.png, 2.png, ... 15.png]
w = 70
h = 60
pdf = FPDF(orientation = 'L')
for image in list_of_images:
pdf.image(image, w=sizew, h=sizeh)
pdf.output("Memory_usage.pdf", "F")
and also wkhtmltopdf
template = Template('''<!doctype html>
<html>
<body>
<div style="display: flex; flex-direction: row">
{% for image in images %}
<img src="{{ image }}" />
{% endfor %}
</div>
</body>
</html>''')
list_of_images = [1.png, 2.png, ... 15.png]
html = template.render(images=list_of_pict)
with open("my_new_file.html", "wb") as fh:
fh.write(html)
p = subprocess.Popen(['wkhtmltopdf', '-', 'Memory_usage.pdf'], stdin=subprocess.PIPE, universal_newlines=True)
p.communicate(html)
p.wait()
but both of them place each picture one under another
解决方案
Just place each image at required coordinates using FPDF:
pdf.image(image, x=50, y=100, w=sizew, h=sizeh)
