A quick way to select a tool in &kolourpaint; is to press the single key shortcut associated with it,
documented below and in the <interface>Tool Box</interface> tooltips. You can also hold
<keycombo action="simul">&Alt;&Shift;</keycombo> while pressing the key, which is necessary when you are
writing text (as the single key shortcuts will be disabled). For example, to select the brush, press
<keycombo action="simul">&Alt;&Shift;<keycap>B</keycap></keycombo> or just B (when not writing text).

<para>The Color Box has 3 main sections: the Color Tablet, the Color Palette

<para>The Color Tablet shows the current foreground color as a square on top

&RMB; the background color is used (except for the <link

arrow to swap the foreground and background colors.  </para>

<para>The Color Palette shows a selection of colors for you to choose
from. The translucent pyramid represents the transparent color. Left-click
on a color to set the foreground color and right-click on a color to set the

Tablet squares. To edit a color in the Color Tablet or Palette, double-click
on it. The <link linkend="tool-color-picker">Color Picker</link> tool allows
you to select a color from the image.  </para>

<para>Color Similarity allows you to work more effectively with dithered
images and photos, in a comparable manner to the <quote>Magic Wand</quote> feature of other paint programs. It applies to transparent selections, as well as the
<link linkend="tool-flood-fill">Flood Fill</link>, <link
linkend="tool-eraser-clr">Color Eraser</link> and <link
linkend="image-autocrop">Autocrop / Remove Internal Border</link> tools. Double-click on the Color
Similarity Selector to choose how similar colors must be to be considered
identical. When using selections in Transparent mode, any color in the
selection that is similar to the background color will also be made
transparent.</para>

<para>
The left picture shows the example image. The right pictures demonstrate the use of a flood fill, with Color Similarity settings of 5%, 15% and 30%. In this example, with a Color Similarity setting of <guilabel>Exact</guilabel>, a flood fill at (80, 100) would only fill one pixel, as the surrounding pixels are similar but not identical. As Color Similarity is increased, more pixels that are similar in color are considered identical, hence the fill extends further.

<para>To quickly invert all channels, you do not need to use this dialog. You can instead

<inlinemediaobject>
<imageobject>
<imagedata fileref="image_reduce_colors.png" format="PNG"/>
</imageobject>
</inlinemediaobject>
</para>

<para>
This reduces the number of colors used by the image or selection, with or without dithering.
</para>

<para>
Dithering generally provides better quality results, however, you may wish to disable it for artistic effects;
<abbrev>e.g.</abbrev> using <guilabel>Monochrome</guilabel> instead of
<guilabel>Monochrome (Dithered)</guilabel> gives a silhouette effect.
</para>

<para>
Another important distinction is that while <guilabel>Monochrome (Dithered)</guilabel> will always reduce the entire image or selection to black and white, <guilabel>Monochrome</guilabel> will do this only if the image or selection contains more than 2 colors.
</para>

<tip>
<para>For a quick, dithered monochrome image or selection, use the <link linkend="image-monochrome">Reduce to Monochrome (Dithered)</link> item of the <guimenu>Image</guimenu> or <guimenu>Selection</guimenu> menu.
</para>
</tip>

<note>
<para>
Changing the number of colors here has no effect on the color depth of the file format. If you want to
change the color depth, you should select it in the file saving dialogs. Note that, confusingly, changing
the color depth also changes the number of colors.

</para>

<para>Resizing the image changes the dimensions of the image without
applying a transformation to the existing contents. Scaling the image will
stretch the existing contents to the new dimensions. <guibutton>Smooth Scale</guibutton>
generally provides better quality results than Scaling, by blending neighbouring colors.</para>

<para>You can express the new dimensions in pixels, or as a percentage of
the original size. If you select <guilabel>Keep aspect ratio</guilabel>, the
width and height will be scaled by the same percentage.</para>

<tip>
<para>
You can free-form <guibutton>Resize</guibutton> the entire image or <guibutton>Smooth Scale</guibutton> the selection using the corresponding handles.
