Currently it supports animated GIF only, but in the nearest future we plan to add multipage TIFF support and migrate AVI Processor to the Graphics Mill architecture. Those who worked with AVI Processor will find animated GIFs in Graphics Mill familiar. To read animated GIF files, you should use GifReader class, to save it - GifWriter. Each GIF frame is presented with GifFrame class. GifReader contains a collection of GifFrames. So to read GIF frames, you should just iterate through the collection either with For Each statement: Code: `Dim objReader As New GifReader objReader.OpenFile "c:\animagif.gif" Dim objFrame As GifFrame For Each objFrame In objReader.Frames objFrame.Bitmap.SaveToFile "c:\frame_" & objFrame.Index & ".gif" Next objReader.Close` or just get necessary frame by index: Code: `If I < objReader.Frames.Count Then objReader.Frames(I).Bitmap.SaveToFile "c:\frame.gif" End If` Writing animated GIF is a piece of cake too. You should create a frame or get it from GifReader and pass it to the AddFrame method: Code: `Dim objReader As New GifReader Dim objWriter As New GifWriter Dim objFrame As GifFrame objReader.OpenFile "c:\animagif.gif" objWriter.OpenFile "c:\result.gif" For Each objFrame In objReader.Frames objWriter.AddFrame objFrame Next objReader.Close objWriter.Close` These code samples are pretty basic and they intended only to give an idea about capabilites of the Graphics Mill in processing of animated GIF files. More detailed code sample you can find in attachments. If you have any problems with it, please feel free to let us know.
