How can create an image from a single page of a multi-page TIFF without ingesting the whole file?

ILYA

I have a huge multi-page TIFF file and all I need is to access and display a single page. If I do something like this:

Image myImg = System.Drawing.Image.FromFile("c:\myimage.tif");
int iPage = 5;
myImg.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page,iPage);

I am still going to load the whole image into memory first. i want to avoid this. Is there a way of ingesting just one page into memory using either standard .NET libraries or some freeware open-source third-party libraries?

Thanks much!

You can use LEADTOOLS Imaging Pro SDK technology in your application.
https://www.leadtools.com/help/sdk/v20/dh/co/rastercodecs.html
You can leverage the RasterCodecs class to load in the desired single page of the multi-page TIF file and then export the single page RasterImage to any image format supported by LEADTOOLS.
Here is some sample code:
using (RasterCodecs codecs = new RasterCodecs())
{
    string inputPDF = @"FILE PATH TO INPUT TIF";
    string outputFile = @"FILE PATH TO OUTPUT IMAGE";
    // Load just the first page of the multi-page TIF
    using (RasterImage image = codecs.Load(inputFile, 24, CodecsLoadByteOrder, 1, 1))
        // Export single page to file
        codecs.Save(image, outputFile, RasterImageFormat.Tif, image.BitsPerPixel);
}

so you need to break up all the pages into single, something like will work.
