ReportLab將頁面大小設置爲字母

我試圖將我的頁面大小設置爲字母，同時仍添加可流動的樣式。請幫我改進我的代碼。ReportLab將頁面大小設置爲字母

# Sample platypus document 
# From the FAQ at reportlab.org/oss/rl-toolkit/faq/#1.1 

# Import some constructors, some paragraph styles and other conveniences from other modules. 
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer 
from reportlab.lib.styles import getSampleStyleSheet 
from reportlab.rl_config import defaultPageSize 
from reportlab.lib.pagesizes import letter 
from reportlab.lib.units import inch 
from reportlab.platypus import Image 
from reportlab.lib.utils import ImageReader 
from reportlab.pdfgen import canvas 


PAGE_HEIGHT = defaultPageSize[0] 
PAGE_WIDTH = defaultPageSize[0] 
defaultPageSize = letter 
styles = getSampleStyleSheet() 
Title = "Comparison Index" 
pageinfo = "platypus example" 
Image3 = 'BTALogo.png' 



# Define the fixed features of the first page of the document 
def myFirstPage(canvas, doc): 
    canvas.saveState() 
    canvas.setFontSize(22) 
    canvas.setFont('Helvetica-Bold', 36) 
    canvas.drawString(50, 670, 'Health & Welfare') 

    canvas.setFont('Helvetica-Bold', 24) 
    canvas.drawString(50, 625, 'Benchmark Comparison Report') 

    canvas.setFont('Helvetica', 16) 
    canvas.drawString(50, 550, 'Prepared for:') 

    canvas.setFont('Times-Roman', 12) 
    canvas.drawString(inch, 0.25 * inch, "First Page/%s" % pageinfo) 
    canvas.restoreState() 

# Since we want pages after the first to look different from the first we define an alternate layout for 
# the fixed features of the other pages. 
# Note that the two functions use the pdfgen level canvas operations to paint the annotations for the pages. 
def myLaterPages(canvas, doc): 
    canvas.saveState() 
    canvas.setFont('Times-Roman', 23) 
    canvas.drawString(inch, 0.75 * inch, "Page %d %s" % (doc.page, pageinfo)) 
    canvas.restoreState() 

def myThirdPages(canvas, doc): 
    canvas.saveState() 
    canvas.setFont('Times-Roman', 9) 
    canvas.drawString(inch, 0.75 * inch, "Page %d %s" % (doc.page, pageinfo)) 
    canvas.restoreState() 


# Create a story and build the document 
def go(): 

    doc = SimpleDocTemplate("Comparison Index.pdf", pagesize=letter) 
    Story = [Spacer(1, 2 * inch)] 
    style = styles["Normal"] 
    for i in range(3): 
     bogustext = ("Paragraph number %s. " % i) * 4 
     p = Paragraph(bogustext, style) 
     Story.append(p) 
     Story.append(Spacer(1, 0.2 * inch)) 

    logo = "PlanOffered.jpg" 
    im = Image(logo, 7 * inch, 2 * inch) 
    Story.append(im) 

    logo = "BTALogo.png" 
    im2 = Image(logo, 4 * inch, 4 * inch) 
    Story.append(im2) 

    doc.build(Story, onFirstPage=myFirstPage, onLaterPages=myLaterPages) 


if __name__ == "__main__": 
    go()

目標是能夠添加流量但不能改變頁面的大小。我們需要這份報告的大小。

問題是什麼嗎？運行這個爲我生成一個帶有字母大小頁面的文檔 –

是的，我意識到這一點。我修好了它。 –

試試這個....

def PrintID(request,std_id): 
    response = HttpResponse(content_type='application/pdf') 
    response['Content-Disposition'] = 'attachment; 
    filename="somefilename.pdf"' 
    buffer = BytesIO() 

    p = canvas.Canvas(buffer) 
    p.setFont('Helvetica-Bold', 36) 

    p.setPageSize((400, 400)) 
    p.drawString(100, 100, "Hello world.") 

# Close the PDF object cleanly, and we're done. 
    p.showPage() 
    p.save() 
    pdf = buffer.getvalue() 
    buffer.close() 
    response.write(pdf) 
    return response

它的工作原理........
