As(s)embler Plus VB Picture Processing Fun: by Robert Rayment. (Updated for XP)I like to have everything at my finger tips as the screen shot shows. If you prefer the minimalist approach see the excellent filter prog by Manuel Santos ( I have used a modification of a couple of his filters and have included his bitmap). Stephan Swertvaegher's picture handling prog is great for ideas and delicate changes to pictures ( I haven't seen Kevin Gadd's prog but which I believe is based on a dll written in C). The ripple effect is based on Didar ul Alam's prog. My prog has some of their features but also includes scrolling, shifting, rotation, zooming (plus anti-alias rotation and zooming), rectangle extraction, resizing and crazy mirrors. Looping is also included which can cycle through changes until stopped. All but a couple of things are duplicated in mcode. For some effects this is only included for completeness but has a dramatic effect on others. The programmer is usually the last person to find all the errors so - Constructive comments welcome.

Newton's Cradle & Metronome by Robert Rayment. (UPDATE using QueryPer... API) Simulates the known movement of balls in an idealized Cradle with variable speed & improved timing for the Metronome. Two progs. Win98 & WinXP Zip file 24 KB.

A PinBall Demo by Robert Rayment. UPDATED for XP, wayward pixels killed, scoring and ball capture improved. See notes in the Form. Zip file 116 Kb.

Demo Spheroid Wrapping by Robert Rayment. This takes any bitmap & wraps it around a sphere. This can then be moved, rotated and magnified. The prog can be run with VB or machine code. Controls are keys only for this demo. Win 98 Zip file 85 KB.

Interactive Filter Design by Robert Rayment. IMPROVED: Input, VB or ASM, some user filters by Malcom Ferris(NZ) included in a *.ufi file. I was in two minds about submitting this since it is really for my own use. Included are some 3x3 filters from Unlimited Realities and Manuel Santos. With this prog filters can be up to 5x5. What would interest me is whether anyone can find designs that are significantly different from the 3x3 filters with the filter formula I've used. Win98, Zip file 72KB.

NASM Editor, assembler & Tutorial by Robert Rayment. (Version 3.5) This is an MDI RTB editor specifically for creating and producing pure machine code and DLLs for use with VB. I've written it because nearly all the refs on the Web are for DOS-asm, C-asm and All asm Windows progs. These are mostly confusing and none of it is needed to write useful VB-asm progs. nasmw.exe is needed to make full use of this package (Latest Web refs for NASM are given (NB Can also be obtained from A1VBCODE.com)). In the pack there is a Help file (make sure to read Requirements about the placement of nasmw.exe and other progs), a Tutor file and a crib for all the NASM mnemonics. Bin files ( called in VB using CallWindowProc) and DLL files can be created with temporary files to clear errors and then permanent files. Starter stub files for Bins and DLLs are menued. There are also 5 Bin examples and 7 DLLs showing a variety of ways that these can be written, in particular the NASM syntax. Reference code for the editor was taken from all over the place. If you're a beginner there's still a lot of work to do before you can write useful asm progs but, hopefully, this will get you over the first hurdles. Good luck! Win98, Zip 120KB.

MMX Crib by Robert Rayment. (Updated 6 Mar 2006, tidy-up & added snippets) For those interested in mixing VB & assembler. Demonstrates all the MMX instructions plus a few snippets. Win98 (exe WinXP) Zip 18 KB.

Sphere by Robert Rayment. (Update with Latitude shift & Long for Byte Array) Demo of spherical wrap, rotate and tilt. Win98 (Zip 21 KB).

Despeckler by Robert Rayment.(Update Re-load added) This attempts to demonstrate some basic patching, dust & scratch removal, de-spotting, pixel painting, sharp, soft, dark & brightening for pictures. The operations can be for the whole picture or a selected area with varying blemish sizes and thresholds. Color selection and a magnifier help with correcting small areas. Example bitmaps are included. Can be run as VB or VB+ASM. The ASM makes extensive use of MMX. -------------------------------------------------- Optionally the use of i_view32.exe (freeware from www.irfanview.com) is demonstrated for loading and saving any image file format in VB....See Notes.txt. -------------------------------------------------- Thanks to VBAccelerator.com (Dialog class), VBSpeed (Timer class) and Ulli (ToolTips class - PSC CodeId=42051) (Exe tested on WinXP) Win98, Zip 205KB.

Extractor by Robert Rayment. Extracts a band of colors from a picture and shows them on a black & white picture which can be saved as a 1-bpp bmp mask. Also can extract rectangles or shapes plus a mask or resize to a rectangle. ASM can be toggled for large pictures. Win98 (exe WinXP) Zip 110 KB.

Dither by Robert Rayment. (Updated 26/11/02 Jump table used in ASM, 2-color saving corrected, improved scroll bars) This produces a 2-color bitmap from any original using a variety of methods and can be saved or printed. The program can be run in VB or VB+ASM. The structure of the asm file roughly follows that of the VB code and so should be useful for those new to assembler. The asm code is in a bin file but could be stored in a res file or made into a dll or a class (see buggy). See Notes.txt for more info. Zip 59KB, Win98 & exe tested on WinXP.

Picture Collector by Robert Rayment.(UPDATE with New Look dialog (Thanks redbird77) and maintain aspect ratio) (Upgraded for WinXP - thanks Carles) I had a request to write a quick program to collect a selection of picture files (standard VB ones) from a folder and save them as thumbnails to a single bmp. Shows multi-selection dialog and parsing input string and - might be useful - could be embellished. Win98 Zip 6 KB.

Fast Bit-shifting Class Demo (Update + ASM files)by Robert Rayment. Thanks to David Fritts for highlighting this method on PSC (CodeId=45885). I've corrected the assembler and Ulli has recast it in his own inimitable style with some explanations. In fact the method is the self-same as that used by Dmitry (CodeId=11830) a few years ago. The main point is that, when comparing fast EXEs, this bitshifting class is over 10 times quicker than the standard VB way using functions of the form 2^p. This description is extended in Notes.txt.

Fancy Scrollbars by Robert Rayment. If wanted, the purpose here is to get away from the standard VB scrollbars and add other colors, shaping & effects. Lots of examples included to show almost unlimited design possibilities. One reusable bas Module provided & a set of short fixed Subs to include on the Form containing the scrollbars. No extra dependencies & just one recommended API (Sleep). Full instructions given. (exe WinXP) Win98, Zip 39 KB.

Doodle Bytes by Robert Rayment. (Updated) This shows a variety of animations using the technique of drawing to a byte array and blitting to the screen with a palette. Win98 (exe WinXP) 14 KB.

Layers Demo by Robert Rayment. (Update5 fileops correction) This started as a layers demo but grew a bit to include some effects and drawing tools. Individual pictures can be resized, clipped, lassoed, rotated have effects and drawn on and a merged picture can also have all these apart from lassoing and rotating. The transparency can be varied for each picture apart from the background...etc. Too many things to describe them all here so please read the Help. The screenshot was made with this prog but PSPro used to convert to jpeg. Difficult to be sure all bugs removed so comments welcome. (exe tested on WinXP) Win98, Zip 182 KB including some test pictures.

BmpToJpeg GDI+ version (Quality & Regions) by Robert Rayment. Converts bmp to jpeg. See effect of quality before saving. Selected regions can be of a different quality. Regions can be rectangle, rounded rectangle, oval or lasso. It appears that there are intermittent problems with ijl15.dll and Win2K. So this prog has used cut, paste & adapted code from Carles P V (CodeId=42376) & MrBoBo (CodeId=42488) for GDI+ which, if you haven't got it, can be downloaded at - www.microsoft.com/downloads/release.asp?releaseid=32738 - Install gdiplus.dll in your system or app folder. (Exe tested on XP Home) Win 2K, Win 98, Zip 241 KB (Couple of bmps included).

CUBOID CITY by Robert Rayment. Demo of what can be done with wire-frame cuboids, using pure VB & a couple of APIs for creating & animating scenes. Several thousand cuboids can be happily handled but make sure to compile the animation program!. Two progs, one to draw cuboid pictures (including random mazes) and the other to use the output files (*.ccc) and animate them. There are lots of options to help with drawing - too many to describe here. The animation program uses planar perspective for speed with mostly pure VB. Speed & direction set by distance of cursor from center of display, eye (camera) level and block heights changeable, collison detection and reaching the pyramid in the mazes explodes all. These progs provide a start for a full 3D wire-frame drawing program. Example ccc files included. See Notes. (Exe tested on WinXP) Win98. Zip 115 KB.

Brush Vectors by Robert Rayment. (Added binary input/output. Fast version, see Help for info on Fast redraw.) This is a vector drawing program using brushes with up to 8 widths, 4 directions, color & transparency. A brush stroke is started with a left-click(or space bar), move mouse to draw & left-click(or space bar) to end it. Each stroke is stored in a vector array which can be saved to a file. Colors can be parked and also saved to a file. The advantage of vectors is that they are full 24-bit color can be stretched/shrunk to a new canavs size. File format can be ASCII (.vec) or binary (.veb). Vec files are usually much smaller than BMP and veb files often smaller than GIF or JPEG. There aren't many aids to drawing yet apart from a fill tool and Shift & Ctrl keying to force vertical & horizontal drawing. So it needs some skill to produce nice pictures. Undo/Redo is almost unlimited, vectors can be deleted from the last drawn or clipped down to the last undo. Deleting any individual vector is not included yet. Important to read the help file to get the most out of this prog. (exe tested on WinXP), Win98, Zip 48KB.

Knob-Thumb-wheels & Skins Demo by Robert Rayment. An earlier version has been deleted. Three programs. The first develops and tests bmp strips from a starting image where, for knob wheels the central rotating part's radius and incremental angle can be set as well as, for thumb wheels, number of repeated images. The second program makes compressed True Color 2D arrays of images and masks using zlib.dll (version 1.1.4.0 from www.winimage.com/zlibdll/). For most efficient inflating zlib needs the original uncompressed size. For pictures the original width and height are needed and this is stored at the beginning of the compressed picture array, from which the uncompressed size can also be calculated. The third program uses zlib.dll to inflate the images from a resource file. This is a headerless form, skin, controls & fonts resizing demo using some standard methods (plus some WAV sounds also in the resource file) - a test bed for trying out things. There are 2 full skins but the demo also stores some bitmaps in image boxes, which then serve as buttons and source for tiled skinning. When compiled all the images are then contained within the exe.
