Hello. I need to convert the IFormFile which I receive in a ASP.NET Core controller method into an Aspose.Pdf.Document without saving the file to my hard drive. How can i do this?

You can obtain the image stream from IFromFile in the controller method and it to generate a PDF from below code snippet:

try
{
    // Convert IFormFile to Stream
    using (Stream stream = imageFile.OpenReadStream())
    {
        // Create a new PDF document
        Aspose.Pdf.Document oPdf = new Aspose.Pdf.Document();
        Aspose.Pdf.Page oPage = oPdf.Pages.Add();

        // Set page margins to zero
        oPage.PageInfo.Margin.Bottom = 0;
        oPage.PageInfo.Margin.Top = 0;
        oPage.PageInfo.Margin.Left = 0;
        oPage.PageInfo.Margin.Right = 0;

        // Create an image object and add it to the page
        Aspose.Pdf.Image oImage = new Aspose.Pdf.Image();
        oPage.Paragraphs.Add(oImage);

        // Set the image stream from the IFormFile
        oImage.ImageStream = stream;

        // Save the PDF to the specified path
        oPdf.Save("{Path to save the PDF}");
    }

    return Ok("Image uploaded successfully");
}
catch (Exception ex)
{
    // Handle exceptions
    return StatusCode(500, $"Internal Server Error: {ex.Message}");
}
