Image Processing with GoDot


The (by far) biggest part of the available program modules is meant for processing 4Bit data. These are activated inside of the window "Image Operators" by clicking the gadget "Execute".

Standard modules can give a strange touch to a picture, enhance it, change its type, can combine several pictures, sever parts from a picture, move it, enlarge it, scale it down, add colors, or take colors away. The results of this processing can be printed, but may also be an intermediate product to process other pictures.

An other part of the modules facilitates work with the system itself and with connected peripheral devices. Modules of this type produce another dot in their names which is shown as first character inside of GoDot. These modules are called "system modules".

Some of the modules work according to the principles of convolution. We gathered them up in an own list. Please read there to get an idea of what 'convolution' means.

Several modules do change the 4Bit area but allow however to withdraw an action by engaging a module a second time. Some of the modules are referring to colors at their work, others to shades of gray. Finally there are modules that intensify their effects when used more than once. In our description of the modules we show these properties.

To picture to you the changes a module can cause, we confined ourselves to two example pictures. The original of the colored picture below was created by the rather known illustrator NAGEL. We imported the 8 color picture from an Amiga with ldr.IFF. The other picture was produced by Wolfgang and has allusions to very famous standards (King Tut of DPaintII). Even this picture was originally created on an Amiga. However, all pictures you'll see on our web pages actually are C64 pictures. They descend from a C64 memory exactly as they can be seen here.
