I have an arraylist with images (System.drawing.Images). Each of these images are 24bpp with full color.
I need to save 1 arraylist to 1 file (so I'll need a multipage Tiff). But they also have to be compressed with Group4 compression.
I'm using C#.NET

I've been reading the documentation for some time now, but I can't figure out how to do this.

If you are trying to go from a System.Drawing.Image object, you will need to create a byte array or MemoryStream and load it into a LEADTOOLS object that way.

Once you have created a RasterImage (assuming you are using our .NET libraries), you can use the RasterCodecs.Save() method to save this to a file as a 1bpp Tiff CCITT Group 4 image.

As for combining them into a multipage image, you can either use the Append Save mode when saving the image, or use the RasterImage.AddPage method and then call Rastercodecs.Save only once for the multipage RasterImage object.
