字符串绘制是操作PDF的基本功，本文将给大家介绍几种常用的绘制函数
- 标准绘制函数canvas.drawString(80, 700, 'Standard String')
- x轴右对齐绘制函数canvas.drawRightString(80, 680, 'Right String')
- 轴对称绘制函数canvas.drawAlignedString(60, y, str(number))
- 中心对称绘制函数canvas.drawCentredString(width / 2, 550, 'Centered String')
demo 源码
# string_alignment.py
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter
def string_alignment(my_canvas):
width, height = letter
my_canvas.drawString(80, 700, 'Standard String')
my_canvas.drawRightString(80, 680, 'Right String')
numbers = [987.15, 42, -1,234.56, (456.78)]
y = 650
for number in numbers:
my_canvas.drawAlignedString(60, y, str(number))
y -= 20
my_canvas.drawCentredString(width / 2, 550, 'Centered String')
my_canvas.showPage()
if __name__ == '__main__':
my_canvas = canvas.Canvas("string_alignment.pdf")
string_alignment(my_canvas)
my_canvas.save()
