the right hand side of &chalk;'s main window. There are three palettes which

The <guilabel>Opacity</guilabel> slider and spin box are used to set the
|
||
|
|
opacity when drawing (opacity is the opposite of transparency, i.e. 100%
|
||
|
|
opaque is 0% transparent, and vice versa).

</para><para>
|

In the <guilabel>Mode</guilabel> drop down box, you can choose a drawing
|
||
|
|
mode. This changes the actual effect that results from drawing on the image
|
||
|
|
(for example, only changing the saturation or lightness).

</para><para>
|

|
|
With the <guilabel>Paint direct</guilabel> option, you can determine whether
|
||
|
|
you want to paint directly on the current layer, or on a temporary layer which
|
||
|
|
is then composited onto the actual layer. This makes a difference especially
|
||
|
|
when using relative low opacity values.</para>

The <guilabel>Ratio</guilabel> setting defines the shape of the

star. A ratio of 0% will create a star with no inner area (when drawing the
|

|
|
star, the two lines that make up a star point, overlap). Increasing the ratio
|
||
|
|
will slowly make the star more outlined (the two lines are <quote>pulled
|
||
|
|
apart</quote>). A star with a ratio of 100% is a regular polygon.

The setting in the <guilabel>Threshold</guilabel> slider and spin box
|
||
|
|
determines how near the color of a point should be to the color of the
|
||
|
|
starting point of the fill, in order for the fill to spread out over the
|
||
|
|
former point. A higher threshold will therefore fill areas that have less
|
||
|

similar colors, a lower threshold limits the spread.

strength</guilabel> influences how much paint you will apply to the canvas,

and <guilabel>Wetness</guilabel> determines how wet the paint is when it is

applied. You can dry the paint later.

On the top left, you can select what blending mode should be used for the
|
||
|
|
selected layer. These are the same possibilities as you can choose from for
|
||
|
|
drawing modes.

The slider/textbox at the top right determines the opacity of the selected
|
||
|
|
layer. 0% opacity corresponds to 100% transparency, and vice versa.

The list shows all layers and their names, and offers various controls for each
|
||
|
|
layer. The eye icon toggles whether the layer is visible or not. The link icon
|
||
|
|
is used to link layers together. The lock icon determines if the layer is
|
||
|
|
locked or not. Locked layers cannot be edited.
|
||
|
|
</para><para>
|
||
|
|
Below the layer list, there are some other controls. You can create a new
|
||
|
|
layer, move the current layer up or down, show the layer's properties and
|
||
|
|
delete it.

There are some more handy tricks you can do with the mouse within the list.
|
||
|
|
Right-click on the layer list and select <guilabel>New Folder</guilabel> to
|
||
|
|
create a new layer folder, which you can use to group layers in. You can also
|
||
|
|
drag and drop layers to change their order. To do so, click on the bottom part
|
||
|
|
of the list item representing the layer, drag the mouse, and release the mouse
|
||
|
|
button at the desired position. If you click at the top part of the list item
|
||
|
|
instead, you will get a text field so that you can rename the layer.
