PureBasic is a new "high level" programming language based on established BASIC rules. PureBasic is similar to any other BASIC compiler you may have used, whether for the Amiga or PC. Learning PureBasic is very easy! PureBasic has been created for the beginner and expert alike. Compilation time is really fast. We have put a lot of effort into its realization to produce a fast, reliable and system friendly language.
The syntax is simple but the possibilities are endless with PureBasics advanced features, such as pointers, structures, procedures, dynamically linked lists and much more. The experienced coder will have no problem in gaining access to any of the legal OS structures or API objects.
PureBasic is a portable programming language which currently works on AmigaOS (680x0 and PowerPC), Linux, MacOS X (PowerPC) and Windows computer systems. This means that the same code can be compiled natively the three systems and still use the full power of each. There are no bottlenecks like a virtual machine or a code translator; the generated code produces highly optimized executables regardless of the OS on which it is compiled. The external libraries are mainly written in hand optimized assembler, which produces very fast commands, often much faster than the C/C++ equivalent.
Main features:
- Huge set of internal commands (800+) to quickly and easily build any application or game
- All BASIC keywords are supported
- Very fast compiler which creates highly optimized executables
- No external DLLs, runtime interpreter or anything else required when creating executables
- Procedure support for structured programming with local and global variables
- Access to full OS API for advanced programmers
- Easy but very fast 2D game support trough dedicated libraries (DirectX, SDL, ...)
- Easy and high quality 3D support based on OGRE
- Optimal use of the available hardware by using highly optimized (assembly) commands
- Source code is portable between AmigaOS, Windows, MacOS X and Linux, for games and applications
- Dedicated editor and development environment
- Integrated debugger to easily trace programming bugs.
Technical Features:
- 486, Pentium (Pro, II, III) support
- Built-in arrays, dynamically linked lists, complex structures, pointers and variable definitions
- Supported types: Byte (8 bits), Word (16 bits), Long (32 bits), Float (32 bits) and also user defined types (structures)
- Built-in string types (characters)
- Constants, binary and hexadecimal numbers supported
- Expression reducer (grouping constants and explicit numbers together)
- Standard arithmetic support in respect of sign priority and parenthesis: +, -, /, *, and, or, lsl, asl, lsr, asr
- Very fast compilation (about 300 000 lines/min on a P200)
- Procedure support for structured programming with local and global variables
- All Standard BASIC keywords: If-Else-EndIf, Repeat-Until, etc.
- External library support to manipulate objects like BMP pictures, windows, gadgets, SDL, etc.
- External libraries are fully written in hand optimized assembler for maximum speed and compactness
- The Linux API functions are fully supported as if they were BASIC keywords
Inline assembler
- Precompiled structures with constants files for extra fast compilation
- Configurable CLI compiler
- System friendly, easy to install and use

DespeckleHelper is the process of removing speckles from images (especially bitmaps created using a scanner). Speckles are artifacts which are extra pixels (or collections of extra pixels) that can occur in scanned images because of imperfections in the scanner hardware, or because of dust or dirt being present on the camera, scanning surface or even the document being scanned.
The document structure analysis and character recognition are usually done in several phases:
- scanning
- thresholding
- skew detection and correction
- despeckle or speckle removal
- line removal
- border removal
- detection of preprinted elements (like boxes)
- page orientation detection and correction
- layout analysis
- classification
- character recognition
Each step must be completed well enough for the performance of the sequence and result to be successful. Steps that follow the despeckle are inefficient if the correction fails.
DespeckleHelper provides a successful method for automatically improving the quality of document images and a marked decrease in OCR error rates. The method is easy to use - we view it as a pre-OCR cleanup operation, and it takes a very small amount of the computational effort of the OCR process itself.
DespeckleHelper expects as input a monochrome image.

Parallels VM Compressor is a powerful, easy to use virtual hard disk management tool that helps users to significantly reduce the virtual disk size!

Compressor works with all major virtualization solutions, including Parallels Workstation, VMware Workstation, Server or GSX Server, or Microsoft Virtual PC or Virtual Server.

LinesHelper can remove the noise lines from faxed documents.

Faxed documents often contain annoying horizontal lines due to communication noise on the telephone line. Scanned document in some cases, also have horizontal or vertical lines due to the banding or folding of papers. By utilizing LinesHelper these lines can automatically be removed.

The document structure analysis and character recognition are usually done in several phases:

scanning
thresholding
skew detection and correction
despeckle or speckle removal
line removal
border removal
detection of preprinted elements (like boxes)
page orientation detection and correction
layout analysis
classification
character recognition

Each step must be completed well enough for the performance of the sequence and result to be successful. Steps that follow the line removal are inefficient if the correction fails.

LinesHelper finds and removes horizontal and vertical lines and repairs overlapping text and graphics on binary images. The line removal filter can also be configured to reconstruct horizontal and vertical lines, redrawing them straight with smooth edges. LinesHelper expects as input a monochrome image.
