Hi! Sorry for the delay, I missed this... With version 1.10.1, you can now access fonts and images from the StructuredTextPage object. For example:

//Initialise the MuPDF context. This is needed to open or create documents.
using MuPDFContext ctx = new MuPDFContext();

//Open a PDF document
using MuPDFDocument doc = new MuPDFDocument(ctx, "path/to/file.pdf");

// Obtain a MuPDFStructuredTextPage from the first page of the document, preserving the images.
using MuPDFStructuredTextPage sTextPage = doc1.GetStructuredTextPage(0, preserveImages: true);

// Enumerate the MuPDFStructuredTextPage
foreach (MuPDFStructuredTextBlock block in sTextPage)
{
    // Image block
    if (block is MuPDFImageStructuredTextBlock imageBlock)
    {
        // Access the image.
        MuPDFImage image = imageBlock.Image;

        // Save it to a file
        image.Save(@"C:\Users\Giorgio\Downloads\test.png", RasterOutputFileTypes.PNG);

        // Get an RGB representation
        byte[] pixelBytes = image.GetBytes(PixelFormats.RGB);
    }
    // Text block
    else if (block is MuPDFTextStructuredTextBlock textBlock)
    {
        // Enumerate the lines in the text block.
        foreach (MuPDFStructuredTextLine line in textBlock)
        {
            // Enumerate the characters in the text block.
            foreach (MuPDFStructuredTextCharacter character in line)
            {
                // Each MuPDFStructuredTextCharacter contains a MuPDFFont
                MuPDFFont font = character.Font;

                // Useful properties you access on the font.
                string fontName = font.Name;
                bool bold = font.IsBold;
                bool italic = font.IsItalic;
                bool monospaced = font.IsMonospaced;
                bool serif = font.IsSerif;
            }
        }
    }
}
