The problem of losing the image when you play Flatten

[mhkim8282]

Hello.
I used Spire.PDF to play Flatten with Python, but it's becoming Flatten with the image gone.
I want to play Flatten without the image disappearing, what should I do?

Hello

Below is the source code that downloaded the PDF file and flattened the PDF file again.

If there is an existing image, the image does not come out.

Thank you.

Code: Select all

    def download_file(url, file_path, flatten_file_path=None, type=None):
        try:
            response = requests.get(url, stream=True)
            if response.status_code == 200:
                with open(file_path, 'wb') as f:
                    for chunk in response.iter_content(chunk_size=1024):
                        if chunk:
                            f.write(chunk)

                if type == "form":
                    doc = PdfDocument()
                    # Load a PDF file
                    doc.LoadFromFile(file_path)
                    doc.Form.IsFlatten = True
                    doc.SaveToFile(flatten_file_path)

                    doc.Close()
           
                return True
            else:
                return False

        except Exception as e:
            raise e

Hello,

Thanks for your feedback.
I simulated a pdf file with image and form fields. After flattening, the image is not lost. I uploaded this file for your reference. The problem should be related to the file, so please provide us with your result document so that we can investigate more accurately. Thanks in advance.

Hello

Thank you for your answer.

Attached is the original PDF and the PDF file processed by Flatten.
The original PDF has an image, but the image disappears when the platten processing is performed.

Is there a way to deal with it?

Thank you.

Have a nice day.
