Wrap text in PIL

Wrap text in PIL

To wrap text in an image using the Python Imaging Library (PIL), now known as Pillow, you can follow these steps:

  • Import the necessary libraries:
from PIL import Image, ImageDraw, ImageFont
  • Open an image or create a new one:
# Open an existing image or create a new one with a white background image = Image.new("RGB", (800, 600), "white")
  • Create an ImageDraw object to draw text on the image:
draw = ImageDraw.Draw(image)
  • Set the font and size:
font = ImageFont.truetype("path_to_font_file.ttf", font_size)

Make sure to replace "path_to_font_file.ttf" with the path to a TrueType font file on your system and specify the desired font size with font_size.

  • Define the text you want to wrap:
text = "This is a long text that you want to wrap in the image."
  • Set the maximum width for wrapping:
max_width = 400 # Adjust this value as needed
  • Define the line height and initial y-coordinate:
line_height = 30 # Adjust this value as needed y = 50 # Adjust this value as needed to control the vertical position
  • Use a loop to wrap and draw the text:
lines = [] current_line = [] for word in text.split(): test_line = current_line + [word] test_size = draw.textsize(" ".join(test_line), font=font) if test_size[0] <= max_width: current_line.append(word) else: lines.append(" ".join(current_line)) current_line = [word] # Append the remaining line lines.append(" ".join(current_line)) # Draw the wrapped lines on the image for line in lines: draw.text((50, y), line, fill="black", font=font) y += line_height

This code will wrap the text according to the max_width while maintaining the specified line height. Adjust the values of max_width, line_height, and y as needed for your specific layout.

  • Save or display the resulting image:
image.save("output_image.png") image.show()

Make sure to replace "output_image.png" with your desired output file name.

This code will wrap the text and draw it on the image. You can customize the font, size, colors, and layout as needed for your specific requirements.
