my code :class OriginalImageSaving(IImageSavingCallback):

    def image_saving(self, args: ImageSavingArgs) -> None:
        # if args.current_shape.is_image:
        #     originalImageFile = args.image_file_name
        #     shape = args.current_shape
        #     shape.image_data.save(f"{originalImageFile}")
        print()      
    document = aw.Document(source_file)
    saveOptions = aw.saving.MarkdownSaveOptions()
    a = saveOptions.image_saving_callback()
    saveOptions.image_saving_callback = OriginalImageSaving()
    document.save(f"{result}.md", saveOptions)

The error you are encountering, TypeError: type 'aspose.words.saving.IImageSavingCallback' is not an acceptable base type, suggests that there may be an issue with how you are implementing the IImageSavingCallback interface in your code.

To resolve this issue, ensure that your class correctly implements the IImageSavingCallback interface. Here’s a basic example of how to implement this interface in C#:

using Aspose.Words;
using Aspose.Words.Saving;

public class ImageShapePrinter : IImageSavingCallback
{
    private int mImageCount;

    public void ImageSaving(ImageSavingArgs args)
    {
        args.KeepImageStreamOpen = false;
        Console.WriteLine($"Image #{++mImageCount} is being saved.");
        // Additional logic for saving the image can be added here
    }
}

// Usage
Document doc = new Document("path/to/your/document.docx");
HtmlSaveOptions options = new HtmlSaveOptions();
options.ImageSavingCallback = new ImageShapePrinter();
doc.Save("output.html", options);

Make sure that your implementation of IImageSavingCallback is correctly defined and that you are using the appropriate namespaces. If you are using Python, ensure that the Aspose.Words library is correctly installed and that you are following the correct syntax for implementing interfaces in Python.

If you continue to face issues, please check the version of the Aspose.Words library you are using, as there may be compatibility issues with the interface implementation.

If you need further assistance, feel free to provide more details about your implementation or any additional error messages you are encountering.

@alexey.noskov Hello! How’s it going? We need to get the original image and not the compressed image.LLM has requirement for image clarity. :sob:

@David_Matin Unfortunately, there are no news regarding this feature. And it is not likely to be resolved any time soon.
Will it resolve the problem if we provide an option that will allow setting image resolution in MarkdownSaveOptions? This will allow you to control the images quality.

@alexey.noskov Hi! That sounds great!I think it will solve the current problem.If an option exists to restore the quality of the image when converting to markdown, then image recognition becomes more usable!

@David_Matin Thank you for additional information. This will be much easier to implement.
