@calistasoft,

I have observed your requirements and like to share that you need to traverse the pixel by pixels to identify any certain area bearing certain RGB value can be considered as blank area. There is no other option available other than this to achieve the goal as from Aspose.Imaging perspective all pixels bear some RGB and that you need to verify.
