在Report Lab - Python中创建4 x 5网格的图像

from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

c = canvas.Canvas("grid.pdf", pagesize=letter)

rows = 4
cols = 5

grid_width = letter[0] / cols
grid_height = letter[1] / rows

for i in range(rows):
    for j in range(cols):
        x = j * grid_width
        y = i * grid_height
        c.rect(x, y, grid_width, grid_height)

c.save()
