Hi all,
I keep getting the issue where my text does not fit in the margin lines when I want Julius to create a report for me via a PDF. It does not allow the text to wrap around and stay within the page, it just kind of continues on and gets cut off.
If anyone has found a solution to this, I’d love to hear it.
Hey,
Great question! I’ve had some success with manually explaining what I want via font type, spacing and such. I’ve found, in python at least, if you define the margin and width in the code that it helps. Additionally, if you add the draw_wrapped_text function that it also makes sure that your text wraps around, but that is the furthest I’ve gotten as of right now.
From the code below you get this:
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
from reportlab.lib.units import inch
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont
# Create a PDF file
file_name = "example_thesis_reportlab.pdf"
c = canvas.Canvas(file_name, pagesize=letter)
# Define margin and width
margin_left = 50
margin_top = 750
max_width = 4 * inch
line_height = 20
# Function to wrap text
def wrap_text(text, max_width, font_name, font_size):
words = text.split()
lines = []
current_line = []
for word in words:
test_line = ' '.join(current_line + [word])
width = pdfmetrics.stringWidth(test_line, font_name, font_size)
if width <= max_width:
current_line.append(word)
else:
lines.append(' '.join(current_line))
current_line = [word]
if current_line:
lines.append(' '.join(current_line))
return lines
# Function to draw wrapped text
def draw_wrapped_text(c, text, x, y, max_width, font_name="Helvetica", font_size=12):
c.setFont(font_name, font_size)
lines = wrap_text(text, max_width, font_name, font_size)
for line in lines:
c.drawString(x, y, line)
y -= line_height
return y # Return the new y position
# Title Page
c.setFont("Helvetica-Bold", 16)
c.drawString(margin_left, margin_top, "Title: The Impact of Climate Change on Global Agriculture")
c.setFont("Helvetica", 12)
c.drawString(margin_left, margin_top - line_height, "Author: John Doe")
c.drawString(margin_left, margin_top - 2 * line_height, "Date: September 9, 2024")
c.showPage()
# Abstract
c.setFont("Helvetica-Bold", 14)
c.drawString(margin_left, margin_top, "Abstract")
abstract_text = "This thesis explores the various impacts of climate change on global agriculture, including changes in crop yields, water availability, and pest dynamics.

I then adjusted the max_width section to 7*inches and got this:

c = canvas.Canvas(file_name, pagesize=letter)

margin_top = 750
max_width = 7 * inch
line_height = 20

def wrap_text(text, max_width, font_name, font_size):
words = text.split()
lines = []
current_line = []
for word in words:
test_line = ' '.join(current_line + [word])
width = pdfmetrics.stringWidth(test_line, font_name, font_size)
if width <= max_width:
current_line.append(word)
else:
lines.append(' '.join(current_line))
current_line = [word]
if current_line:
lines.append(' '.join(current_line))
return lines
# Function to draw wrapped text
def draw_wrapped_text(c, text, x, y, max_width, font_name="Helvetica", font_size=12):
c.setFont(font_name, font_size)

c.drawString(x, y, line)

return y # Return the new y position

But I still want to play around with the function to see what I can achieve.
