Based on the current implementation of the GmailGetMessage tool in the LangChain framework, it does not support parsing of HTML content from emails. The tool is designed to only process plain text content and ignores HTML content or any other content type. This is evident from the following code snippet:

if email_msg.is_multipart():
    for part in email_msg.walk():
        ctype = part.get_content_type()
        cdispo = str(part.get("Content-Disposition"))
        if ctype == "text/plain" and "attachment" not in cdispo:
            message_body = part.get_payload(decode=True).decode("utf-8")
            break
else:
    message_body = email_msg.get_payload(decode=True).decode("utf-8")

In this code, ctype is the content type of the part and cdispo is the content disposition. If ctype is "text/plain" and "attachment" is not in cdispo, then the payload of the part is decoded and assigned to message_body. If the content type is not "text/plain" or if it is an attachment, then the part is ignored.

To fix this, you would need to modify the GmailGetMessage tool to also process parts with a content type of "text/html". This would involve adding an additional condition to check for "text/html" content type and then using an HTML parser to extract the text from the HTML content.

As for reading or extracting text from images in emails, this is a more complex task that would likely require the use of Optical Character Recognition (OCR) technology. Currently, the LangChain framework does not have built-in support for OCR. You would need to integrate an external OCR library into the GmailGetMessage tool to achieve this.

Please note that these modifications would require a good understanding of the LangChain framework and Python programming. If you are not comfortable making these changes yourself, you may want to consider hiring a professional developer or software development company to assist you.
