Image Processing in VB. A complete rewrite of the 2001 version. Read all uncompressed BMPs, GIF, JPG and PNM files. Write BMP, GIF and PNM files. Also capture/return external Bitmaps and StdPics. Extended Color Depth/Palette options. Dithers enhanced. New Blue Noise Dither. More than 20 new operations - including alphablending and color combination, Sharpen, Blur, Edge, Equalization, and color correction. Particular support for very large BMPs >16M in size. The compiled .dll is many times quicker than in the IDE. Apps using previous (2001)version will require checking and recompilation.
This is an Integer only implementation of John Korejwa's CJPEG class (derived from v0.9) - about 30% faster when compiled with all optimisations. To test add it to his project.
Give your Gfx card a real workout. A DirectX8 scene manager with demos. Lights, camera and action for a wide range of 3D figures, you determine what they do and what they look like. The supporting engine (rvtDX.dll) in this archive. A good further tutorial in DirectX8. Obviously needs DX8 on your machine. (333k)

This is a first!. A Typelib and DLL for the use of Direct3D9 from VB6. Consult Readme and Doco for useage. Requires DirectX 9.0c to be operational on your machine. (163K)
A very simple but highly addictive solitare game where the object is to remove large connected blocks of tiles with the same color. Make your mark in the hall of fame. 16 combinations from small to huge, 3 to 6 colours. To clear the hall of fame delete the .DAT file.
A full implementation of Variable Length Integer and Variable Length Fractional Maths. This is a Global DLL so that functions are available as if they were standard VB. Contains a full range of functions incl. GCD, LCM and Factorials, all basic math functions, as well as Exp,Log, Sin, Cos, Tan and their inverses in Fractional Maths. Once compiled you only need to reference the dll to use it. No need to declare an instance of it.
Ever saved a JPG or GIF you loaded into your App and then looked at the result? - this will fix that problem. This submission features capture of any GDI object on your app with a hDC (say Form or PictureBox), lets you do some simple image processing on it (eg. Flip or Resize), then allows you to colormap it, dither it and save it as a BMP or a GIF. Yes a GIF! Entirely coded in VB and presented as a DLL with extensive demo program, this could be the beginning of a great togetherware gfx processor. Contains OctTree color quantization and Remapping to MS,New or Fixed colormaps, with or without Dithering. Serious bug or idea submissions (with explain and code snippets) welcome.
Multiple Slider, Scroller controls in one OCX. Now Mousewheel support has been added, in addition to MS properties so that it can be used as a drop-in replacement.
A very extensive(192K) VB dll for interacting with the GDI. Capable of scaling output to all (or part of) screen or printer. Plots, Lines, Rect, Ellipse, Polygon, Text. Fills and Outlines - Solid, Patterned, Gradient and Image. Wide, and patterned pens, Fancy text, scaling and mapping etc.etc. Plenty of meat to pick off this turkey.....
Evaluator consists of a Compiler & Execution class for EPrograms made by compiling a string containg regular expressions. Its quite extensible. Well documented and with a test program. Evaluator is designed as an Activex dll

This is a completely original Image format Encoder/Decoder implemented as a single class based on using a Wavelet Transform to compress an image. Similar to JPGs in approach, this can also save a LOSSLESS variety of file when Quality=100
