<｜begin▁of▁sentence｜>### Instruction:
How can you calculate the layout for a given text, starting at a specific point on a Cairo canvas, with constraints on the width and the option to wrap text if it does not fit?
### Response:
from igraph.drawing.text import CairoTextDrawer
import cairo

# Create a cairo surface and context
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 600, 50)
context = cairo.Context(surface)

text_drawer = CairoTextDrawer(context, halign='left')
layout = text_drawer.get_text_layout("This is a sample text", x=50, y=20, width=200, wrap=True)

# Print the calculated text layouts
for x, y, line in layout:
    print(f'Text at ({x}, {y}): {line}')

# Save the surface to a file
surface.write_to_png('text_layout.png')
