Simple but useful (for somebody) utility for stripping ID3v1 and ID3v2 tags from any file. It's API based and much faster than version 1.0. It removes tags from all files inside selected folder (or subfolders).
Some cool animations with some useful techniques like antialiasing, SafeArray, dynamic creating of picture objects using API, partial window redrawing and other. Code is relatively fast but can be much faster using assembler optimizations (maybe later).
Generator of sine and square signal through DirectSound + Oscilloscope. Amplitude and frequency (1 to 22050 Hz) modifier + amplitude modulator included.
Shows various image resampling (resizing) interpolation filters like: Nearest Neighbor (Box, Point), Bilinear (Triangle, Tent, Bartlett), Bicubic Cardinal spline, Bicubic B-spline, Bicubic BC-spline (Mitchell & Netravali) with an interactive diagram and Windowed Sinc with these windows: Bartlett, Blackman, Blackman-Harris, Bohman, Cosine, Gauss, Hamming, Hann, Kaiser, Lanczos, Parzen, Rectangular, Welch. For all interpolation filters is shown spatial domain. Everything is developed under Visual Basic using SafeArray technique to access image pixels. Application is also able to extend edges if the filter demands that by copying edges content out of bounds. Sample pictures are included.

Shows various image resampling (resizing) area interpolations like: Nearest Neighbor (Box, Point), Bilinear (Triangle, Tent, Bartlett), Bicubic cardinal spline, Bicubic B-spline, Bicubic BC-spline (Mitchell & Netravali) with an interactive diagram, Bell, Gaussian and Windowed Sinc with these windows: Bartlett, Blackman, Blackman-Harris, Bohman, Connes, Cosine, Gaussian, Hamming, Hann, Kaiser, Lanczos, Parzen, Rectangular, Welch. All interpolation filters are shown in spatial domain. Stair interpolation and normalization are also supported. Everything is developed under Visual Basic using SafeArray technique to access image pixels. Application is also able to extend edges if the filter demands that by copying edges content out of bounds. Sample pictures are included.
This editor is only GUI application for Netwide Assembler. You can build binary file, dynamic-link library (DLL) or executable file (EXE). It has good compiler and linker error handlers (error line is highlighted after compiling). You can get help for any instruction or directive by pressing F1 (just like in Visual Basic). Project has some executables not allowed on PSC, so download here (+ help + libs + samples +++): http://flashlight.webpark.cz/eindex.htm
