Simple Image Reducer is an GTK application to easily reduce and rotate images. It can be useful for processing digital photos before sending by email or uploading on the Web. Image files can be supplied to the application from the file manager using the context menu "Open with...", or dragging files to the main window.
The Common Pipeline Library provides a highly robust set of functions for manipulating signals and images. It is primarily intended for the building of VLT instrument pipelines, but is also useful for generic data handling. It includes a number of useful low-level data types, medium-level data access methods, standard implementations of commonly-used signal processing and data reduction tasks, and dynamic loading of "recipes" for data processing.
