Gray Image 23 Cpp

Attached is a Mac distribution of a new, 2.3, version of grayimage - a grayscale image processing class library and verification code The new version is more portable: besides a Mac, the source code compiles and correctly runs on various UNIX boxes (Sun/Solaris, HP 9000/7xx, FreeBSD), a BeBox, and even Win95/WinNT. Besides portability and safety embellishments, there are more substantial enhancements: - non-separable (truly 2D) 3x3 convolutions (very optimized and very fast) - much improved handling of TIFF files - non-deterministic filtration - a cuter algorithm for generating fractal clouds. Now, you may easily add your own private (non-obligatory) tags to a TIFF file, and/or look them up. BTW, the code that writes TIFF files shows off an important concept of a safe, one-purpose pointer: a pointer that _physically_ cannot be misused (miscast, left dangling, etc), yet just as efficient as a regular, unprotected C pointer. What: A C++ class library to do many boring and exciting things with grayscale images Keywords: image arithmetics, median filtration, morphological filtration, convolution, lazy image, TIFF, plasma fractals, nondeterministic filter, C++, class library Hot points: - all standard algebra/arithmetics on an image/image slices - LazyImages, and PixelAction iterators, and image streams for fast sweeping actions; - very *fast* convolutions, median filtration, and lookup table substitutions - morphological filtration - assigning an image of _really_ any size to another image _to fit_ - Fractal clouds generator (as an example of a Lazy Image) - non-deterministic filtration (averaging) - reading/writing XWD/PGM/grayscale_TIFF files with automatic input file format recognition The user may now add/look up private and other non-mandatory tags, and iterate over/clone TIFF IFD entries - with a validation code to verify everything - with a commented source and CW9 projects A README file gives more details.
