Draw Shapes, Convert Pictureformats, Design Pictures: You can do everything you would do with an Paintprogram directly from the Commandline with Imagemagick (http://www.imagemagick.org).
With this Codeunit you can draw all primitives directly in Navision (Lines, Triangles, Quaders, Text, Pie-charts) directly in Navision.
This Nav-functions show the basics to work with Imagemagick, the screenshot attached to the ZIP is drawn with this functions, the example Code is inside for demonstration purposes. In combination with my Math-Codeunit you can also draw Piecharts and much more with Sin/Cos/Arc calculation. It is only one single Codeunit w/o any Sidefect. The CU is written in 4.03, but should run on Navision 1.3 till 5/2009.
Things to do: You could speed up the Functions by
a) using Script-Batchfiles instead of drawing every single Function
b) Using the Automation server. If you install the DLL-ImageMagick, you get an Automation server which ist working in Navision. This would also reduce the working time. This will not work for the older Navision-versions.
Feel free to optimize, speed up, expand the functions, as long as you let my name in the Documentation part and publish your extensions to the comunity.
The Function generates a *.bmp with lowest possible size which can be directly imported into Navision-BLOB as shown in the Screenshot.
