我正在使用 ReportLab 生成一个非常简单的报告。它有一些文本、大约 15 张小图像和一些自定义元数据。它可以正常生成并在 Chrome 或 Edge 上打开，但不会在 Acrobat 或 Reader 中打开。当在后两者之一中打开时，它会说“期望一个 dict 对象”，然后只为每一页显示一个空白的白色方块。

我根本没有使用鸭嘴兽，只是 reportlab.pdfgen.canvas。我将在此处放置代码的匿名版本。另外，我对一般编程很陌生，所以请不要评判我的菜鸟错误（就像字面上设置一个变量i来增加；即使我知道一个人很懒（也请忽略表格是图像；那是因为...原因））。

from datetime import datetime
from reportlab.pdfgen import canvas
import pdf_report_utils as pu
import plotly.graph_objects as go

def create_pdf_canvas(year_int, month_int):
    # Create PDF and give PDF a document title
    start_as_date = datetime. strptime(start, '%Y-%m-%d %H:%M:%S')
    month_name = start_as_date.strftime('%B')
    year_name  = start_as_date.strftime('%Y')
    pdf = canvas.Canvas('pdfs/OSP Monthly Summary Report DRAFT - ' +
                        year_name + ' ' + month_name + '.pdf',
                        pagesize='letter'
                        )
    pdf.setTitle('Company Inc Monthly Summary Report')

    # Setting metadata
    pdf.setAuthor("Someone via ReportLab in Python")
    pdf.setTitle("Company Inc Monthly Summary Report DRAFT - " +
                    year_name + " " + month_name)
    pdf.setSubject("An auto-generated report of various data.")
    
    # Making title backdrop

        if i+1 <= len(section_titles): # This keeps it within the list dims
            if px - section_title_height - table_height[i]/2 < 50:
                pdf.showPage()
                pdf.setFontSize(size=14)
                pdf.drawString(50, 700, 'Summary Tables (cont.)')
                pdf.setFontSize(size=10)
                px = 680 # resetting px to top of page
        px = px - section_title_height
        pdf.drawString(50, px, title)
        px = px - table_height[i]/2 - 5
        pdf.drawImage('images/table'+ str(i+1) +'.jpg', 
                        50, px, 510, table_height[i]/2)
        i = i+1
