In the reportlab user guide (page79), this is how the images are inserted into the table.
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'),
])
So based on the above user guide, i assume that to insert images into tables, all i have to do is import image using PIL, image module , load image and use it as data for table.
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()
But instead of inserting the image into the table, i had this message created on the pdf "PIL.Jpegimageplugin.JPEGImageFile mode=RGB size=200x200 at 0x179B1E8"
What could be the problem?
You can use the Image of the ReportLab for image purpose instead of PIL.. hope it helps you. I have modified your code to below.
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()
EDIT: to import cm function, we should use:
from reportlab.lib.pagesizes import A4, landscape
from reportlab.lib.units import cm
