How to save an image in the compression type: JPEG (in tiff)

Sarmad Yousif

I am editing image using "System.Drawing.Imaging" The original image is .tiff compression type: JPEG (in tiff)

The output image doesn't save in same format. I tried this link

It makes me save it as a .jpeg not tiff.

Any help?

You can use the RasterImage class provided by the LEADTOOLS SDK to get the original composition of the file. Loading a file as a RasterImage will provide you access with both the file format and Bits-Per-Pixel which will allow you to retain the original integrity of the file. You can try using the following code for this
string path = @"C:\files\InputTif.tif";
using(var codecs = new RasterCodecs())
using(var img = codecs.Load(path);
codecs.Save(img, path,img.OriginalFormat, img.BitsPerPixel);
