# 创建 PdfDocument 对象并加载源文档
pdf = PdfDocument()
pdf.LoadFromFile("report.pdf")

# 创建附件对象
attachment = PdfAttachment("source-data.xlsx")

# 将附件添加到文档附件集合中
pdf.Attachments.Add(attachment)

# 保存更新后的 PDF 文档
pdf.SaveToFile("report-with-attachment.pdf")

# 创建多个附件
attachment1 = PdfAttachment("source-data.xlsx")
attachment2 = PdfAttachment("meeting-notes.docx")
attachment3 = PdfAttachment("architecture.png")

# 添加到文档附件集合
pdf.Attachments.Add(attachment1)
pdf.Attachments.Add(attachment2)
pdf.Attachments.Add(attachment3)

attachment_files = [    "source-data.xlsx",    "meeting-notes.docx",    "architecture.png"]

for file in attachment_files:
    pdf.Attachments.Add(PdfAttachment(file))

from spire.pdf import *
from spire.pdf.common import *

pdf = PdfDocument()
pdf.LoadFromFile("report.pdf")

# 获取目标页面（这里为第 1 页，索引从 0 开始）
page = pdf.Pages.get_Item(0)

# 读取附件文件
data_stream = Stream("source-data.xlsx")

# 设置图标在页面上的位置和尺寸
# 参数依次为：X 坐标、Y 坐标、宽度、高度
bounds = RectangleF(50.0, 100.0, 16.0, 16.0)

# 创建附件注释
annotation = PdfAttachmentAnnotation(
    bounds,
    "source-data.xlsx",
    data_stream
)

# 设置外观和提示文字
annotation.Color = PdfRGBColor(Color.get_Blue())
annotation.Flags = PdfAnnotationFlags.Default
annotation.Icon = PdfAttachmentIcon.Graph
annotation.Text = "双击打开原始数据表格"

# 将附件注释添加到页面
page.AnnotationsWidget.Add(annotation)

pdf.SaveToFile("report-with-page-attachment.pdf")

bounds = RectangleF(50.0, 100.0, 16.0, 16.0)

page = pdf.Pages.get_Item(0)

annotation.Icon = PdfAttachmentIcon.Paperclip

# 1. 在页面 Canvas 上绘制提示文字
label_text = "附件：生成该图表对应的原始数据"
font = PdfTrueTypeFont("Arial", 10.0, PdfFontStyle.Regular, True)

x_pos = 50.0
y_pos = 150.0

page.Canvas.DrawString(
    label_text,
    font,
    PdfBrushes.get_Black(),
    x_pos,
    y_pos
)

# 2. 获取文字实际宽度
text_width = font.MeasureString(label_text).Width

# 3. 将附件图标放在文字右侧 5 点的位置
icon_bounds = RectangleF(
    x_pos + text_width + 5.0,
    y_pos,
    16.0,
    16.0
)

# 4. 创建并添加附件注释
annotation = PdfAttachmentAnnotation(
    icon_bounds,
    "source-data.xlsx",
    data_stream
)

annotation.Icon = PdfAttachmentIcon.Paperclip
page.AnnotationsWidget.Add(annotation)

font.MeasureString(label_text).Width

from spire.pdf import *
from spire.pdf.common import *

pdf = PdfDocument()
pdf.LoadFromFile("report-with-attachment.pdf")

# 遍历文档级附件
for i in range(pdf.Attachments.Count):
    attachment = pdf.Attachments.get_Item(i)

    # 将附件保存到本地
    with open(attachment.FileName, "wb") as f:
        f.write(attachment.Data)

pdf.Close()
