Using the options box
The options display on the left of the toolbar is a combination of a
combo-box as well as plus and minus adjusting buttons. Pressing the buttons will
change the currently displayed option.

The value of the currently displayed option can be altered by clicking
on the plus and minus buttons. To change a new option or to just look
at the current value of all the options just drop down the combo-box and click
on the value to be changed.
All the values are saved between IconPainter sessions so it is always
wise to check such values as transparency and line width when
creating a new icon. Beginning a new icon will not reset the values. Here are some
explanations of some of the options.
Anti-aliasing
When drawing straight or curved lines (and text) with anti-aliasing switched on will
mean that subtle shading is automatically done to give the illusion of line smoothness.

IconPainter implements anti-aliasing by making the assumption that the
line is being drawn on the background color. For the most part this shouldn't
cause problems but it may detract from the quality of the lines in some situations.
Line width
The line width is self-explanatory. It indicates the width in pixels of any lines
drawn including lines drawn around shapes which are both filled and outlined.
Also see transparency and
color gradient shading.
Shadowing
The shadow option performs a basic shadow operation that
follows the same convention that's used for
color gradient filling.
The default is for shadowing to be off and by pressing the plus button, compass directions
(North,NorthEast..) can be selected to indicate which way the shadow is to be drawn.
The shadow offset indicates the number of pixels of offset to be used when drawing the
shadow in the specified direction. The shadow color is the same color that is
used for drawing the grid lines over the grid window.
