To embark on this creative journey, we will explore: – Loading custom font files into Pycairo. – Leveraging distinct typefaces to enhance visual appeal.

By harnessing the power of custom fonts, we can breathe life into our designs and add a touch of individuality to our projects.

Code

import cairo

# Initialize Cairo surface
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 200, 100)
context = cairo.Context(surface)

# Load custom font file - replace 'CustomFont.ttf' with actual font file path
font_path = "CustomFont.ttf"
custom_font = cairo.ToyFontFace(font_path)

# Set the context's font face to the loaded custom font
context.set_font_face(custom_font)

# Draw text with custom font at position (x=10, y=50)
context.move_to(10, 50)
context.show_text("Hello World!")

# Save the output image
surface.write_to_png("custom_font_output.png")
