As a writer of several scientific image displaying tools I have always wanted a good general purpose image display widget. The goal of the GtkImageViewer widget is to fullfill that gap. Its interaction is a mixture of the user interfaces of Gimp and of xv. The widget itself handles zoom and panning. Additional functionality may be added through callbacks.
Considerable emphasis has been put into the speed and the memory requirements of the widget. While panning only the exposed areas are redrawn, and the zoomed up image outside the display area is never kept in memory.
The GtkImageViewer is perfectly suited to be used by any photo display program and will provide a uniform interface for interacting with images.
See the file gtk_image_viewer/test_wdg.c for a trivial example of the use of this widget.
