hermes

Hermes is a graphics library designed to do a very limited number of things and do them very well. Is designed to convert a source buffer with a specified pixel format to a destination buffer with possibly a different format at the maximum possible speed. The long feature list includes things like palette handling and clearing surfaces to a specific color, conversion of images from one format to another and more.

HotLog

Logging component for Delphi and Lazarus. Version 3.3 (02-05-2019) Multithreaded, object oriented, buffered safe. The log file will be correctly written to disk, even if your application crashes. The logging/parsing/formating and optionnal visual feedback work don't consume your main thread's time. Logging environment to support debugging. Easy-to-use strings formating capabilities. Update of Olivier Touzot's HotLog component 2004,2005. Many Thanks to Olivier.

Motion Detector

The program is designed to measure and store on the HDD the amount of motion measured with the DirectX-compatible camera. The program also can capture video with sound and store them in compressed AVI files. The special feature of Motion Detector is its support of information exchange through UDP protocol. Motion Detector can send motion data in real time to other software for organizing real-time feedback in scientific behavioral experiments. It also can accept commands trough the network or from other software running on the same computer (through UDP) to start/stop video capturing. The program has a ring buffer in RAM to store prehistory - some amount of video before the UDP video capturing event can be saved in the file if needed. Name of the video file can be given in the UDP message or generated locally using auto-increment feature.
