在reportlab user guide(第79页)中,这是图像插入表格的方式。
I = Image('../images/replogo.gif')
I.drawHeight = 1.25*inch*I.drawHeight / I.drawWidth
I.drawWidth = 1.25*inch
P0 = Paragraph('''
<b>A pa<font color=red>r</font>a<i>graph</i></b>
<super><font color=yellow>1</font></super>''',
styleSheet["BodyText"])
P = Paragraph('''
<para align=center spaceb=3>The <b>ReportLab Left
<font color=red>Logo</font></b>
Image</para>''',
styleSheet["BodyText"])
data= [['A', 'B', 'C', P0, 'D'],
['00', '01', '02', [I,P], '04'],
['10', '11', '12', [P,I], '14'],
['20', '21', '22', '23', '24'],
['30', '31', '32', '33', '34']]
t=Table(data,style=[('GRID',(1,1),(-2,-2),1,colors.green),
('BOX',(0,0),(1,-1),2,colors.red),
('LINEABOVE',(1,2),(-2,2),1,colors.blue),
('LINEBEFORE',(2,1),(2,-2),1,colors.pink),
('BACKGROUND', (0, 0), (0, 1), colors.pink),
('BACKGROUND', (1, 1), (1, 2), colors.lavender),
('BACKGROUND', (2, 2), (2, 3), colors.orange),
('BOX',(0,0),(-1,-1),2,colors.black),
('GRID',(0,0),(-1,-1),0.5,colors.black),
('VALIGN',(3,0),(3,0),'BOTTOM'),
('BACKGROUND',(3,0),(3,0),colors.limegreen),
('BACKGROUND',(3,1),(3,1),colors.khaki),
('ALIGN',(3,1),(3,1),'CENTER'),
('BACKGROUND',(3,2),(3,2),colors.beige),
('ALIGN',(3,2),(3,2),'LEFT'),
])
基于上面的用户指南,我假设要将图像插入表中,我所要做的就是使用PIL,图像模块,加载图像导入图像,并将其用作表格的数据。
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import A4, cm,landscape
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import Paragraph, Table, TableStyle
from reportlab.lib.enums import TA_LEFT, TA_CENTER
from reportlab.lib import colors
from PIL import Image as im
a=im.open("temp.jpg")
data=[['1',a],['3','4']]
c = canvas.Canvas("Reportlabtest.pdf", pagesize=landscape(A4))
table = Table(data, colWidths=200, rowHeights=50)
table.setStyle(TableStyle([
('INNERGRID', (0,0), (-1,-1), 0.25, colors.black),
('BOX', (0,0), (-1,-1), 0.25, colors.black),
('BACKGROUND',(0,0),(-1,2),colors.lightgrey)
]))
table.wrapOn(c, 200, 400)
table.drawOn(c,20,50)
c.save()
但不是将图像插入表中,而是在pdf“PIL.Jpegimageplugin.JPEGImageFile mode = RGB size = 200x200 at 0x179B1E8”上创建了此消息
可能是什么问题?

您可以使用ReportLab的图片代替PIL而不是PIL ..希望它对您有所帮助。我已将您的代码修改为以下内容。
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import A4, cm,landscape
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import Paragraph, Table, TableStyle, Image
from reportlab.lib.enums import TA_LEFT, TA_CENTER
from reportlab.lib import colors
from reportlab.lib.units import inch
a = Image.open("path/to/temp.jpg")
a.drawHeight = 2*inch
a.drawWidth = 2*inch
data=[['1',a],['3','4']]
c = canvas.Canvas("Reportlabtest.pdf", pagesize=landscape(A4))
table = Table(data, colWidths=200, rowHeights=50)
table.setStyle(TableStyle([
('INNERGRID', (0,0), (-1,-1), 0.25, colors.black),
('BOX', (0,0), (-1,-1), 0.25, colors.black),
('BACKGROUND',(0,0),(-1,2),colors.lightgrey)
]))
table.wrapOn(c, 200, 400)
table.drawOn(c,20,50)
c.save()

您不设置drawHeight
&amp;代码中的drawWidth
。
