write python code to take in a png picture and write a sentence on it in bold and in white
Here is an example of Python code that uses the Pillow library to open a PNG image, write a sentence on it in bold white text, and save the resulting image:
```
from PIL import Image, ImageDraw, ImageFont

# Open the image file
image = Image.open('input.png')

# Create a font object
font = ImageFont.truetype('arial.ttf', 24)  # use a bold font
font.bold = True

# Create a draw object
draw = ImageDraw.Draw(image)

# Set the text color to white
text_color = (255, 255, 255)

# Set the text to write
text = "Hello, World!"

# Calculate the text width and height
text_width, text_height = draw.textsize(text, font=font)

# Calculate the x and y coordinates to center the text
x = (image.width - text_width) / 2
y = (image.height - text_height) / 2

# Write the text on the image
draw.text((x, y), text, font=font, fill=text_color)

# Save the resulting image
image.save('output.png')
```
Here's how the code works:

1. We open the input PNG image using `Image.open`.
2. We create a font object using `ImageFont.truetype`, specifying the font file (`arial.ttf` in this case) and font size (24). We also set the `bold` attribute to
  Here is an example of how you can use Python to take a PNG picture and write a sentence in bold and white using the `Pillow` library:
```
from PIL import Image

# Load the image
image = Image.open("image.png")

# Define the text to be written
text = "This is a bold and white sentence."

# Define the font and color properties
font = ImageFont.truetype("arial.ttf", 24)
color = (255, 255, 255)

# Draw the text on the image
image.text((10, 10), text, font=font, fill=color)

# Save the modified image
image.save("output.png")
```
This code will load the image file `image.png`, define the text to be written, and then use the `ImageFont` and `Image.text` methods to draw the text on the image. The `ImageFont` method is used to specify the font to use, and the `Image.text` method is used to draw the text on the image at the specified position. The `fill` parameter is used to specify the color of the text. In this case, we are using white text by setting the color to `(255, 255, 255)`.
