Version Graphics4VO - Graphics Development Kit Software
From Geo Tools
Graphics Development Kit for VO Visual Objects Development Kit (DLL) for Graphics. The Graphics Development Kit Graphics4VO is the graphics interface for the programming language Visual Objects with classes, methods and functions for the integration of graphics, images, charts and presentation for the display, printer, plotter, file and memory.
Graphics4VO - Version 10.01 - Latest update on 29 May 2016
The latest important changes
- New gradient and spot functions with color saturation.
- WINDOWS©10 certification after intensive test.
- Supports virtual (multiple) monitors.
- New function for 3D text.
- Font-smoothing (anti-aliasing) for text selectable.
- New round and rounded transparent and opaque Pushbuttons with text and images.
Graphics4VO adds rich graphics for display, printer, plotter, bitmap, metafile and memory bitmap to the programming language Visual Objects, which has rather modest built-in graphic capabilities. By overriding the window classes existing in Visual Objects and adding a method 'paint' it is very simple to equip programs with attractive graphics. Beside elementary pixel graphics and graphic primitives Graphics4VO offers a simple way of creating presentation and business graphics like bar and pie charts, linear diagrams, mathematical coordinates systems, function curves and fractals. With Grapics4VO graphics and scanned images in various graphic formats as well as ArcView Shapefiles can be used in Visual Object applications. The use of world coordinates systems will spare the programmer from doing complex calculations and guarantee image integrity across a wide range of output devices. Buttons and Controls of any shape and with transparent, colored or pictorial background are suitable for programming more interesting user interfaces.
Graphics4VO is developed for use with Visual Objects (Version 2.0 and higher). It is based on 32-Bit-WINDOWS-API. The Graphics Development Kit allows development of graphics oriented Visual Objects applications for 32-Bit Windows operating systems. The GUI classes made available by Visual Objects receive ability to graphic representation by Graphics4VO. Therefore The implementation of graphics into existing programs is very simple. Comprehensive English / German documentations as well as an extensive sample program with many code examples are included.
The Graphics Library Graphics4VO includes classes, methods and functions for integration of graphic elements into Windows applications. It could be used to add graphics to existing applications with minimum labor, or for new development. Knowledge of Windows graphics handling or of Windows API-programming is not required.
The Graphics Development Kit is based upon a very fast graphics display mechanism that allows an exceptionally quick screen drawing. Repainting of an uncovered window is performed from an internal image-bitmap at a speed that makes it not noticeable to the eye. There is no need for the subsequent reconstruction of graphics.
Graphics4VO is offered in two different implementations:
A Dynamic Link Library including the graphics must put down in the call directory of the graphic application that is using it, or in the directory CAVO\BIN. The access to the classes, methods and functions contained in the DLL is made by an interface library, which must be imported into the Visual Objects repository as an AEF-file.
In order to merge Graphics4VO directly into the development system, an AEF-file including the graphics must be imported into the Visual Objects repository. In this case all classes, methods and functions of the Graphics Development Kit are available as source code.
Download of a linkable DLL for testing
The linkable DLL of the Graphics Development Kit Graphics4VO with the detailed documentation can be form the internet as a ZIP packed file. For unpacking the download file you need an unzip program, which you can download
The download of the linkable DLL contains Graphics4VO DLLs for VO 2.0, 2.5, 2.6, 2.7 and 2.8, a in VO importable AEF with the interface to the Graphics4VO DLL, the documentation and an AEF with the compilable demo program including many programming examples. Using the Graphics4VO DLL and interface you can merge graphics into your own applications!
