I am using ReportLab to make a pdf using Python. I want to add a shape to the canvas, and have that shape act as a hyperlink. What is the simplest way to make the rectangle in the following example link to google.com?
from reportlab.pdfgen import canvas
from reportlab.lib.units import inch
c = canvas.Canvas("hello.pdf")
# move the origin up and to the left, draw square
c.translate(inch,9*inch)
# How do I make this rectangle link to google.com?
c.rect(inch,inch,1*inch,1*inch, fill=1)
c.showPage()
c.save()
解决方案 Call linkURL
on the Canvas:
c.linkURL('http://google.com', (inch, inch, 1*inch, 1*inch), relative=1)
The rectangle is the clickable area, so you'd have to match that to the drawn rectangle.
