如果你想在这样的框中添加文本


你可以使用 ​AnnotationBuilder​：

from PyPDF2 import PdfReader, PdfWriter
from PyPDF2.generic import AnnotationBuilder

# Fill the writer with the pages you want
pdf_path = os.path.join(RESOURCE_ROOT, "crazyones.pdf")
reader = PdfReader(pdf_path)
page = reader.pages[0]
writer = PdfWriter()
writer.add_page(page)

# Create the annotation and add it
annotation = AnnotationBuilder.free_text(
    "Hello World\nThis is the second line!",
    rect=(50, 550, 200, 650),
    font="Arial",
    bold=True,
    italic=True,
    font_size="20pt",
    font_color="00ff00",
    border_color="0000ff",
    background_color="cdcdcd",
)
writer.add_annotation(page_number=0, annotation=annotation)

# Write the annotated file to disk
with open("annotated-pdf.pdf", "wb") as fp:
    writer.write(fp)

文本注释如下所示：


Line

如果你想添加这样一行：


你可以使用 ​AnnotationBuilder​：

pdf_path = os.path.join(RESOURCE_ROOT, "crazyones.pdf")
reader = PdfReader(pdf_path)
page = reader.pages[0]
writer = PdfWriter()
writer.add_page(page)

# Add the line
annotation = AnnotationBuilder.line(
    text="Hello World\nLine2",
    rect=(50, 550, 200, 650),
    p1=(50, 550),
    p2=(200, 650),
)
writer.add_annotation(page_number=0, annotation=annotation)

# Write the annotated file to disk
with open("annotated-pdf.pdf", "wb") as fp:
    writer.write(fp)

Rectangle

如果你想像这样添加一个矩形：


你可以使用 ​AnnotationBuilder​：

pdf_path = os.path.join(RESOURCE_ROOT, "crazyones.pdf")
reader = PdfReader(pdf_path)
page = reader.pages[0]
writer = PdfWriter()
writer.add_page(page)

# Add the line
annotation = AnnotationBuilder.rectangle(
    rect=(50, 550, 200, 650),
)
writer.add_annotation(page_number=0, annotation=annotation)

# Write the annotated file to disk
with open("annotated-pdf.pdf", "wb") as fp:
    writer.write(fp)

如果要填充矩形，请使用 ​interiour_color="ff0000"​ 参数。

此方法使用 PDF 格式的“方形”注释类型。
