什么样的记者可用于展示<img>标签？

可以使用ImageReporter类，该类是ReportKit库的一部分。它将图像数据转换为Base64编码，并插入HTML模板中的<img>标签中。以下是示例代码：

from reportlab.lib import colors
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle
from reportlab.platypus import Paragraph, Image
from reportlab.lib.styles import getSampleStyleSheet

from reportlab.lib.enums import TA_CENTER
from reportlab.lib.units import inch

from reportlab.graphics.shapes import Drawing, String
from reportlab.graphics import renderPDF

from io import BytesIO
from base64 import b64encode

class ImageReporter:
    def draw(self, data):
        img = Image(BytesIO(data))
        img.hAlign = 'CENTER'
        return img

    def render(self, result_set):
        buffer = BytesIO()

        doc = SimpleDocTemplate(buffer, pagesize=letter)
        elements = []

        data = [
            ['Name', 'Age', 'Gender', 'Picture'],
            ['John Doe', '25', 'Male', self.draw(open('john.jpg', 'rb').read())],
            ['Jane Doe', '26', 'Female', self.draw(open('jane.jpg', 'rb').read())],
        ]

        table = Table(data)
        table.setStyle(TableStyle([('BACKGROUND', (0,0), (-1,0), colors.grey),
                                    ('TEXTCOLOR', (0,0), (-1,0), colors.whitesmoke),
                                    ('ALIGN', (0,0), (-1,-1), 'CENTER'),
                                    ('FONTNAME', (0,0), (-1,0), 'Helvetica-Bold'),
                                    ('FONTSIZE', (0,0), (-1,0), 14),
                                    ('BOTTOMPADDING', (0,0), (-1,0), 12),
                                    ('BACKGROUND', (0,1), (-1,-1), colors.beige),
                                    ('TEXTCOLOR', (0,1), (-1,-1), colors.black),
                                    ('FONTNAME', (0,1), (-1,-1), 'Helvetica'),
                                    ('FONTSIZE', (0,1), (-1,-1), 12),
                                    ('BOTTOMPADDING', (0,1), (-1,-1), 8),
                                    ('BACKGROUND', (3,1), (3,-1), colors.white),
                                    ('GRID', (0,0), (-1,-1), 1, colors.black),
                                    ]))

        styles = getSampleStyleSheet()
        title=Paragraph("Sample Report with Images", styles["h1"])
        elements.append(title)
        elements.append(table)

        doc.build(elements)
        pdf_data = buffer.getvalue()

        return b64encode(pdf_data).decode('utf-8')

此代码将生成一个 PDF 报告，其中包含用于每个人的个人资料的名称、年龄、性别和照片。 照片将插入到 HTML 模板的  <img> 标记中，并在报告中显示为图片。
