Problem with embed Python plot in email showing blank-CodePudding

I'm trying to send an email with embedded plots with Python. I can't use "cid" to embed the plots due to the fact that some recipients won't be able to see them that way.

I tried to embed the plot via setting the property by SchemaName, but when I send the email the plot show as blank.

My code is the following:

import win32com.client as win32
import seaborn as sns
import matplotlib.pyplot as plt

sns.lineplot(x='Date', y='Total',hue = "Company", 
             data=df1)
plt.savefig('C:/MyDocs/Plot1.jpg')

sns.lineplot(x='Date', y='Total',hue = "City", 
             data=df2)
plt.savefig('C:/MyDocs/Plot2.jpg')

sns.lineplot(x='Date', y='Total',hue = "Name", 
             data=df3)
plt.savefig('C:/MyDocs/Plot3.jpg')

plot1 = 'C:/MyDocs/Plot1.jpg'
plot2 = 'C:/MyDocs/Plot2.jpg'
plot3 = 'C:/MyDocs/Plot3.jpg'

outlook = win32.Dispatch('outlook.application')
mail = outlook.CreateItem(0)
mail.To = myemail
mail.Subject = Testing
attachment = mail.Attachments.Add(plot1, 0x5, 0, "display name1")
attachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "MyId")
attachment = mail.Attachments.Add(plot2, 0x5, 0, "display name2")
attachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "MyId2")
attachment = mail.Attachments.Add(plot3, 0x5, 0, "display name3")
attachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "MyId3")

mail.HTMLBody = html
mail.Send()

But when I receive the email, the outline of the plots are there, but the plots show as blank. I've tried using base64 encoding but the same happens

Thanks!

Embedding images is the most reliable way of transferring images between clients.

Outlook doesn't support Base64 encoded images as well as plots. You can read more about supported and unsupported HTML elements, attributes, and cascading style sheets properties in the Word HTML and CSS Rendering Capabilities in Outlook article.

CodePudding user response：

Your signature images use vml conditionals - you need to force the standard img tags instead of shape\imagedata. Replace <!--[if gte vml 1]> with <!--[if gte vml 9]> and <![if !vml]> with <![if !vmlxyz]> to disable the vml conditionals. It is crude, but it works.
