Python fpdf中图像的分页符

Question

I want to insert some lengthy images (each image can extend to 2 pages) using python fpdf. But the images don't continue to next page once a page break is triggered. How can I print the rest of the images into the next page starting from a given set_y value (header included)?

Answer 1

Although I believe there is a way with fpdf , I suggest you switch to pdfkit / wkhtmltopdf based solution.

I have many similar issues with reportlab , which is very like fpdf , then switched to wkhtmltopdf, feels much better.

With wkhtmltopdf, you could control layout with standard web stack, use CSS and javascript, use a favorite template engine, then convert HTML file to pdf, easier and much more powerful.

Answer 2

Just an example of my above comment,

from fpdf import FPDF
from PIL import Image

pdf = FPDF()
pdf.add_page()

im = Image.open('1.jpg')
width_img, height_img = im.size

#mm = (pixels * 25.4) / dpi
# - 25.4 millimeters in an inch
w = (width_img*25.4)/300
h = (height_img*25.4)/300

pdf.image('1.jpg',0,0,w,h)
pdf.output("yourfile.pdf", "F")

If your pdf-dataset is a data string you can start searching for the " \\r " and/or (multiple) ' \\n ' character(s) using the below code:

chrs = ['\r', '\n', '\n\n']

for item in chars:
     pdf-data.replace(item)

In case its formatted strings in a list:

list = pdaf-data

for list-item in list:
    for list-item in chars:
         pdf-data.replace(item)

In case you read directly from a file use "open file, etc" and readline() .
