save tif c#

I want to add SaveTIF and SaveMultiPageTIF() methods,TIFCompression property and add twain scan feature to image viewer control Could you do it? if yes, I will offer the project to you. I think [login to view URL] can save to tif and set the tif compression. If not ,please met me know what lib you will use. If set TIFCompression= 0, it will not have compression. If set TIFCompression= 1, it will use CCITTFAX3 compression. If set TIFCompression= 2, it will use LZW compression. If set TIFCompression= 3, it will use JPEG compression. e.g. I open multipage TIFF, e.g. it have 3 pages, You will see 3 images in thumbnail list. 1. if I call SaveTIF method, it will save the first page to TIF file. It will output single TIFF file, it have only 1 page. 2. if I call SaveMultiPageTIF method, it will save the 1-3 pages to TIF file. It will output single TIFF file, it have 3 page. if I open JPEG file, then call SaveTIF method or SaveMultiPageTIF method, It will output single TIFF file, it have only 1 page.
