EIKONA user interface is based completely on pull-down menus and dialog boxes. As a consequence, it is extremely easy to operate even for users not very familiar with image processing. Images are stored on image buffers. All that is needed to apply an image processing function to an image is to specify the source and destination image buffer and the related parameters.
Furthermore, implemented functions are grouped into categories according to the type of operation that they carry out, in order to facilitate the search for a specific task. The user can choose the image region where processing is to be performed. Multiple images can be displayed on the screen at the same time, a valuable feature when comparing the results of different processing functions on the same image. EIKONA supports TARGA, PostScript, JPEG, Microsoft Windows BMP, GIF and Postscript file formats, as well as binary (raw) images. Conversion from one image file format to another is possible.
