Interface Controls

This page aims to give an overview of the control system used within Knald to configure the various settings of the program. If you are having some issues in this regard, then this page should be your first port of call.

Push Buttons The push buttons within Knald are used to confirm that you wish to proceed with certain actions, such as loading a normal/derivative map for processing, updating to the Intergrator or saving preferences etc.

Sliders One of the first thing you will probably notice about Knald are the sliders and how many of them there are.

Each slider within Knald has 2 states:-

The first is un-highlighted, which mean the slider is not currently in use.

The second is highlighted to show that the slider is currently active and may be used to adjust values.

Using the sliders is simple and you can adjust many of the settings within Knald simply by moving the corresponding slider to the left or right to increase and decrease its value, which is shown within a spinner.

Spinners Spinners are used to show the current value of their corresponding slider. You can increase and decrease this value by using the up/down arrows on the right hand side of each spinner or by double clicking the box and adding the number manually.

There are two types of values that use spinners in Knald:

Decimal based value

Percentile based value

The decimal based value ranges from 1-100 with an exception of the Max Iterations option, which goes to 1000.

The percentile based value ranges from 0-1000% and is used to control the intensity of various options where a greater range is of benefit.

Checkboxes The checkboxes within Knald are used to toggle various settings which are often simple yes/no selection. When the checkbox is marked with a check mark/tick, the option is active.

Drop-down Menus The drop-down menus within Knald are used as a container for settings where there are multiple options available that all relate to the same setting. Clicking on the drop-down and selecting an option will make that option active.

Input Fields The input fields within Knald are used to enter the path of a file which is to be saved, or to add or change a variable such as a suffix to the saved file.

Toolboxes The toolboxes within Knald are used to open a dialog box or save window in which the desired location of the final saved image can be chosen.
