Reportlab新线在长线上

Question

我需要一个新行,所以我可以在PFD中看到一种格式,我尝试添加页面宽度,但它没有工作,我使用/ n的其他东西,它不起作用.这是我的代码.我可以手动添加一个格式,因为我需要显示从数据库获取的信息,并在一个长行中获取信息.

def PdfReportView(request):
    print id
    # Create the HttpResponse object with the appropriate PDF headers.
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'filename="PatientReport.pdf"'
    c = canvas.Canvas(response, pagesize=letter)
    t = c.beginText()
    t.setFont('Helvetica-Bold', 10)
    t.setCharSpace(3)
    t.setTextOrigin(50, 700)
    t.textLine("Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.")
    c.drawText(t)
    c.showPage()
    c.save()
    return response

Answer 1

您可以使用textLines(),如果你有\n在你的文字输入:

t.textLines('''Lorem Ipsum is simply dummy text of the printing and 
typesetting industry. Lorem Ipsum has been the industry's standard dummy text 
ever since the 1500s, when an unknown printer took a galley of type and 
scrambled it to make a type specimen book.''')

如果你的文字是一行,你可以使用textwrap模块将它分成几行:

from textwrap import wrap

text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book."

wraped_text = "\n".join(wrap(text, 80)) # 80 is line width

t.textLines(wraped_text)
