• Rotation — defines the angle of head rotation in degrees
• Head Tracking — controls whether the tool head bends around
the path of the user’s stroke, or remains at a fixed angle
• Style — determines the behavior of the Colored Pencil tool tip
when using a stylus
Choose Tilt to change the style through a linear progression based
upon the stylus tilt. Choose Tip to mimic using the very tip of a
pencil. Choose Edge to mimic using the pencil’s edge.
• Softness — defines the softness of the pencil lead, controlling
how easily pressure or velocity break up the lead and cause it to
powder into the canvas dents, or to smudge when applied
• Trace check box — allows the Colored Pencil tool to select the
pigment color by sampling the data below the center of the tool
Important! When you hold down the mouse button to begin the
stroke, note that a single sample is performed and the resulting
color is used for the duration of the stroke.
Using the Marker tool
The Marker tool
lets you apply pigment that resembles drawing
with a marker on a canvas. Marker pens are a slightly wet medium,
though generally not wet enough to interact with other wet media.
The pigment goes on the canvas with a multiply function, simulating
the interaction of using a pen repeatedly on the same spot. Pens
generally have a very sharp fall-off at the stroke edge, and there is full
canvas penetration even at light pressure.

Using the Watercolor Brush tool
You can use the Watercolor Brush tool
to simulate the transparent
strokes of watercolor painting. Watercolor brushstrokes reveal the
canvas texture and are wet in terms of how they interact with other
strokes when you smear or mix them together. For more information
see “To dry or wet an Art Media layer” on page 632.
To reload the Watercolor Brush tool with color, you can

• reload the brush by sampling from the Mixer page

Watercolor Brush tool options include
• Shape — defines the shape of the brush tip
• Size — defines the size of the tool head in pixels
• Thickness — defines the aspect ratio of the tool head. This setting
is active only when the Fixed angle Head Tracking option is
chosen.
• Rotation — defines the angle of head rotation in degrees
• Head Tracking — determines whether the tool head bends around
the path of the user’s stroke, or remains at a fixed angle
• Viscosity — defines the rate at which the material on the brush is
applied, and thus the length of the stroke before your paint runs
out
• Firmness — defines the amount of splay in the brush, how the
rendered line gets wider with more pressure, and how well it
penetrates the surface on to which it is painting
• Bristle size — affects the underlying noise function for texture and
application of paint
• Auto Clean check box — cleans the brush and reloads it with fresh
paint at the start of a new stroke
Note: When unmarked, the brush head is not cleaned at the start
of the stroke. Instead, the dirty head has a small amount of the
current color added to whatever dirty head state exists from the
previous stroke.
• Clean button — cleans the head and start the next stroke with
fresh paint or pigment
• Trace check box — allows the current Art Media tool to select the
pigment or paint color by sampling the data below the center of
the brush regardless of the layer type.

Using the Palette Knife tool
The Palette Knife tool
interacts with the medium on the canvas.
Generally, you use it with strokes placed by the Oil Brush tool as this is
the only tool that applies large amounts of its medium. As the mass of
the medium reduces in a spot, there is less to smear and using the
Palette Knife tool has less effect. This means that the Crayon tool,
which applies very little medium, is only slightly affected by the Palette
Knife tool.
The method of loading or cleaning the Palette Knife tool is similar to
the Oil Brush tool. You can clean it automatically after each stroke,
retain the color picked up from the canvas, or allow manual cleaning.
You can use the Palette Knife tool to apply pigment or smear it.
Paint strokes applied by the Palette Knife tool are wet in terms of how
strokes interact with other strokes by smearing or mixing together. For
more information, see “To dry or wet an Art Media layer” on page 632.

Using the Smear tool
The Smear tool lets you smear existing pigment, including pigment
that has no volume on the canvas, such as pencil strokes. The tool
simulates the effects of dragging a cloth or finger through chalk or
pencil strokes on a canvas.
You can use the Smear tool to create a smudging effect on dry
pigment, or to create a smearing effect on wet pigment.

Working with advanced
color features
Corel PaintShop Pro has many advanced color features that let you
work with color in many ways. For example, you can change the color
depth of your images to prepare them for printing or the Web. You
can control how your monitor displays colors and manage colors for
output. You can also split images into color channels.
This section presents the following topics:
• Understanding color depth
• Viewing color depth information
• Increasing the color depth of an image
• Decreasing the color depth of an image
• Understanding color reduction methods
• Understanding palette options
• Working with image palettes
• Understanding color and color models
• Understanding how monitor colors and print colors differ
• Calibrating your monitor
• Working with color management
• Using color channels
Understanding color depth
Color depth, also called bit depth, refers to the number of colors each
pixel in an image can display. As the color depth increases, the number
29
654
Corel PaintShop Pro X8 User Guide
of colors an image can display increases. Each pixel’s color information
is stored in a certain number of computer bits — from 1 bit to 48 bits.
In a 1-bit image, each pixel can display only one of two colors — black
or white. In images with greater bit depth, each pixel can display one
of an increasingly large number of colors. High-end digital camera
photos saved in the camera’s RAW format contain the most colors, but
they also require more hard drive space, and more system memory to
display and work on them.
In Corel PaintShop Pro, you can use the following color depths:
• 2 colors
• 16 colors
• 256 colors
• 8-bit per channel RGB
• 8-bit per channel Grey
• 16-bit per channel RGB
• 16-bit per channel Grey
Before you change the color depth of your image, consider the
following:
• Many effect and correction commands work on higher color
depth images only. After you finish working on an image, you can
decrease its color depth and save it in another format.
• Computer monitors also have a color depth that is determined by
the monitor’s capabilities as well as the selected color setting. If
you display an image with a higher color depth than the monitor
can display, the image has some color distortion.
• Some file formats limit the number of supported colors so that
images display correctly on a variety of monitor types. For
29

example, GIF images, a popular format for the Web, contain up to
256 colors (8-bit depth).
Viewing color depth information
You can use Corel PaintShop Pro to view the color depth information
for images. You can also check the color depth of a monitor to ensure
it supports the color depth of the images with which you are working.
The number of colors actually used in an image is usually less than the
color depth. For example, a 16 million-color image is capable of
displaying that many colors, but may only use 50,000 colors. You can
use Corel PaintShop Pro to view the number of colors used in an image
or layer.
To view the color depth of an image
Edit workspace
• Choose Image Image Information.
The Current Image Information dialog box appears. The color
depth value for the image is displayed in the Pixel Depth/Color
field in the Image group box.
You can also view the color depth information on the Status
bar. The color depth information appears after the two
numbers that display the pixel dimensions of the image.
You can also view color depth information on Overview palette
by pressing F9, clicking the Info tab, and viewing the Color
Depth field.

Increasing the color depth of an image
If an image has a color depth of less than 24-bit, you may want to
increase the color depth so you can use a wider range of effect and
correction commands, many of which only work on images with 16
million colors. Depending on the color depth of your image, you can
also increase an image to 16 colors (4-bit) or 256 colors (8-bit).
To increase the color depth of an image
Edit workspace
• Choose Image Increase Color Depth, and choose one of the
following:
• 16 color palette
• 256 color palette
• RGB - 8 bits/channel
• RGB - 16 bits/channel
Color depths not available for the active image are grayed out.
