This function will convert the selected area into a color negative, and then
the original image is placed over the original in a series of blocks.  The
blocks are randomly placed, and the size of the block can be selected.

\title "Line Art"
\next "mrx_pseudocol"

This tool allows you to create lines, in a selected area, where there are
edges in the original image.  The best way to learn about this function is
to experiment with it.

\node "mrx_pseudocol"
\title "Pseudo Color"
\next "mrx_mononeg"
\prev "mrx_lineart"
This function will change a selected regions color based on the image's
monochrome brightness.  The new colors range from \{ \ts i \tc 11 blue \}
(for cold), through \{ \ts i \tc 10 green \} (for warm), and finally to \{
\ts i \tc 9 red \} (for hot).

\endnode

\node "mrx_mononeg"
\title "Mono Negative"
\next "mrx_lumaneg"
\prev "mrx_pseudocol"
This function will create a Black & White negative.  This will use a
monochrome generator, (\{ \tc 9 Red \tc 1 + \tc 10 Green \tc 1 + \tc 11 Blue
\} )/3, and then taking the negative of this value.

\lab "abs" The Absolute value of a number \{ \ts i x \} is always the
positive value of that number.  The absolute value function is represented by
|\{ \ts i x\} |, where \{ \ts i x \} is any real number.  For example, if \{
\ts i x \} is -9, the absolute value would be: |-9| = 9, and if \{ \ts i x \}
is 9, the absolute value would be: |9| = 9.  A basic knowledge of absolute
values is necessary for understanding how a negative is created.

The negative is created by reversing each pixel's position on the brightness
scale.  This is accomplished by taking the pixel's brightness and subtracting
it from 255, and then taking the absolute value of this new number.  For
example, a white pixel (255) will become black (255 - 255 = |0| = 0), and a
black pixel (0) will become white (0 - 255 = |-255| = 255).

This will create a B&W negative using a monochrome generator, ( \{ \tc 9 Red
\} * .3) + ( \{ \tc 10 Green \} * .59) + ( \{ \tc 11 Blue \} * .11), and then
create a negative of this.

\node "mrx_colorneg"
\title "Color Negative"
\next "mrx_poster"
\prev "mrx_lumaneg"
This tool will create a full color 24 bit negative.  This function could be
used for special effects, or for changing a color negative back to a color
positive.  There are not color corrections for the three color componenets of
the image before the negative function is applied.

This effect will contour the selected region into a set number of levels.
You will be given a slide control gadget to select the number of posterize
levels.  This type of effect is commonly used on \{ \ts i Hard Rock \ts n and

\endnode

\node "mrx_solar"
\title "Solarize"
\next "mrx_pixel"

This function changes the image colors based on each pixel's monochrome
brightness.  The new colors will range from \{ \tc 9 Red \} for the dark
pixels, through \{ \tc 10 Green \} for the middle grey levels, and \{ \tc 11
Blue \} for the brightest pixels.

\title "Pixelize"
\next "mrx_colorderiv"

\node "mrx_colorderiv"
\title "Color Derivative"
\next "mrx_edgeline"
\prev "mrx_pixel"
The derivative is the rate of change in color from one pixel to the next.  If
this rate of change is high, bright colors will be produced in the selected
area, and if the rate is low, darker colors will be produced.  These new
colors are the result of the derivative being applied the component colors \{
\tc 9 Red\tc 1 , \tc 10 Green\tc 1 , and \tc 11 Blue\} .

This is an operation that swaps the \{ \tc 9 Red\tc 1 , \tc 10 Green\tc 1 ,
and \tc 11 Blue \} color components in the image.  This operation is \{ \ts i

will be re-obtained.

This tool will take the average brightness of a region, specified by you, and
then changes the entire area to this average brightness.  In adiition to this
the edges of this area will be set to a color, of your choosing.  The edges
will dither to the center color.

This will convert the image into a series of black lines.  These lines are
proportional to the brightness of the image in that area.  The brighter the

Warp morphing is one  of \{ \ts b Imagemaster R/t\} 's most interesting
tools.  This function allows you to transform a single image into a \{ \ts i
warped \} reproduction of the original image.  For example, if your image was
a face, you could \{ \ts i elongate \} the nose or \{ \ts i shrink \} the
eyes.  The only limit to how far an image can be changed and distorted
is your imagination and patience.

Morphing is not a very complex process.  This manual will provide morphing
definitions and tuorials for both warp and compose morphing, as well as a
section on morphing hints.  After studing these sections on morphing you
should be able to produce excelent quality morphs.  After the basics you will
also want to look at \{ \ts b Imagemaster R/t\} 's special morphing tools
that can turn an ordinary morph into a spectacular morph.
