SketchBlock 3.4 - Digital Sketching For The Amiga

Smooth Tool

The smooth tool allows you to apply subtle smoothing effects. It applies a gausian blur the area of the brush stroke.

When the Smooth tool is active the settings for the tool can be modified via the settings panel in the Tools Window.(Shown Right)

The following attributes can be controlled.

Opacity: The degree to which the smudged colour overwrites the existing image is controlled by the opacity. Opacity varies from 0 to 100% with 100% completely covering the original, and 0% being completely transparent and making no change to the image. Values can be adjusted using the slider or directly entering a number into the adjacent integer gadget.
Scale: Increase the area to me smoothed.
Radius: The radius of the gaussian smmoth convolution more radius is more smoothing but slower.
Pressure: The next switches affect the behaviour of the erase tool when a tablet with pressure sensitivity is used.
- Opacity: Checkmarking this will enable the opacity to be varied with pressure, again in a range from 10% up to 100% of the value set with the opacity slider.
- Size: Vary the size of the smoothed area with pressure.
Progressive: If the progressive switch is enabled, then the smudge area builds up as the stylus / mouse moves back and forth during the same stroke, ie with lifting the stylus or releasing the left mouse button. For the effect to be noticable the opacity slider must be set to less than 100%. With a very low opacity and repeated strokes a very subtle gradient of colour intensity can be obtained.
Show Brush: whether to display the brush n the sketching area.

To pass ARexx commands to the Smooth tool you must use the SketchBlock ARexx command COMMANDTOOL

Sets the Smooth settings to the provided values.

Retrieves the current settings via a STEM varaible.

STEM/K: Pass the variable to which the settings will be added. The values will be added to the stem variable useing the name above with no index component. eg If the STEM var was FOO pressure size will be added as FOO.PRESSURESIZE
