The ivTools include the ivReader and the ivWriter.
The ivReader is a browser-like software for displaying images. If the image is an iv image, the ivReader can display the messages which are hidden in the image by clicking the button with "eyes".
The ivWriter is used to make iv images, which can edit text or draw something, such as, lines, rectangles, circles, etc..
The iv image is an image in which some messages are hidden, such as the title, the names of people, locations, time, copyright, explanations or simply drawing etc.
The iv image uses popular formats (currently support PNG, BMP, RGB and TIFF formats). It is convenient to keep the notes and the image in one file and to display the notes at exact positions on the image. When the image is copied, transferred, or saved, the notes are never lost.
ivTools will allow you to easily view and create iv images.
