\node "mrg_horflip"
\title "Horizontal Flip"
\next "mrg_horflip"
\prev ""
This tool will flip the image information in the selected area horizontally.
Image distortion, potentialy desired, may occur if a rectangular area
selector is not used.

\next "mrg_rotclip"

This tool will flip the image information in the selected area vertically.
Image distortion, potentialy desired, may occur if a rectangular area
selector is not used.

\node "mrg_rotclip"
\title "Rotate Clip"
\next "mrg_motblur"
\prev "mrg_vertflip"
This tool will take the specified region, and rotate it a specified amount.
The rotated area will be placed into a new buffer.  You will also be able to
adjust the aspect ration of the rotated buffer.

Since not all images are created using square pixels, you may need to adjust
the aspect ratio of the clip.  The initial aspect ratio is a part of the
original buffer, and this can only be changed by using the \{ \tc 10 \ts i
Set Buffer Aspect & DPI \} in the \{ \tc 10 \ts i Buffer \} panel.  If the
image uses square pixels, then set the aspect ratio to 100.  This will not
change the aspect of the rotation, which is what you want.

You will need to compensate for any input images that are not square, but
have square output.  You may wish to \{ \ts i strech \} the image aspect so
that the area becomes square, and then rotate the area.

\node "mrg_motblur"
\title "Motion Blur"
\next "mrg_impexp"
\prev "mrg_rotclip"
This tool allsows you to create a \{ \ts i blur \} effect.  It is important
to remember that this is one of \{ \ts b Imagemaster R/t\} 's slowest, yet
most powerful tools. This function takes a  moderate amount of time to
accomplish.  You are also able to specify the length of the blur, and the
direction.
\endnode

\node "mrg_impexp"
\title "Implode/Explode"
\next "mrg_spiralblur"
\prev "mrg_motblur"
This allows you to create another type of blur.  If \{ \ts i implode \} is
selected the blur will be inward, and if \{ \ts i explode \} is selected the
blur will be outward.

\endnode

\node "mrg_spiralblur"
\title "Spiral Blur"
\next "mrg_mirror"
\prev "mrg_impexp"
This allows you to create a \{ \ts i spiraled \} blur effect.

\ce \{ \ts b Spiral Blur Example \}

\endnode

\node "mrg_mirror"
\title "Mirror"
\next "mrg_wavedist"
\prev "mrg_spiralblur"
This tool allows you to \{ \ts i mirror \} any horizontaly isolated side,
vertically isolated side, or any quadrant of the selected area.  The provided
controls allow for many variations on this theme.  The mirrored effect will
be totally enclosed in the specified region.

\ce \{ \ts b Mirror Example \}
\endnode

\node "mrg_wavedist"
\title "Wave Distort"
\next "mrg_caricat"
\prev "mrg_mirror"
This allows you to create an effect similar to those produced by "funhouse
mirror".  You can specify the bend and warp to be applied to the selected
area.

\node "mrg_caricat"
\title "Caricature"
\next "mrg_dome"
\prev "mrg_wavedist"
This distortion is similar to an optical distortion caused by a concave lens.

\endnode

\node "mrg_dome"
\title "Dome"
\next "mrg_zigzag"
\prev "mrg_caricat"
This distortion is similar to an optical distortion caused by a convex lens.

\ce \{ \ts b Dome Example \}
\endnode

\node "mrg_zigzag"
\title "Zig Zag"
\next "mrg_droop"
\prev "mrg_dome"
This tool will randomly zig and zag the image in both horizontal and vertical
directions.

\flushimage
\ce \{ \ts b Zig Zag Example \}

\endnode

\node "mrg_droop"
\title "Droop"
\next "mrg_realigncolor"
\prev "mrg_zigzag"
This tool will randomly droop the image in both the horizonyal and vertical
directions.  You may specify the maximum distance a droop can occur on either
axis, if an axis is set to 0 there will be no droop on that axis.

\endnode

\node "mrg_realigncolor"
\title "Re-align Color Guns"
\next "mrg_radialwave"
\prev "mrg_droop"
This tool can be used to correct misalignments caused by scanning errors, or
to create a 3-d glasses effect.  You can adjust all three of the color
componenets by as much as ten pixels with increments as small as 1/10 of a
pixel.

\endnode

\node "mrg_radialwave"
\title "Radial Wave"
\next "mrg_90rotate"
\prev "mrg_realigncolor"
This effect is similar to what occurs when  astone is dropped in a still
pond.  You can control the intensity (size of the stone), period (the size of
the ripples), and phase (the time ellapsed since the stone was dropped).

\image "clips/radwave.iff" c
\flushimage
\ce \{ \ts b Radial Wave Example \}

\endnode

\node "mrg_90rotate"
\title "90 Degree Rotate"
\next "mrg_perspective"
\prev "mrg_radialwave"
This allows you to rotate the image exactly 90 degrees clockwise or anti-
clockwise or do a 180 degree rotation.  This function is much faster than the
general rotation tool, and should be used if the desired effect is a
rectangular rotation.

\endnode

\node "mrg_perspective"
\title "Perspective Scale"
\next "mrg_xspecsoverunder"
\prev "mrg_90rotate"
This allows you to specify the rotation, translation, and scale for the X, Y,
and Z axis.  You will be presented with a rectangle that represents the image
after modification.  If you select the \{ \ts i \tc 10 Grab \} button, for
any of the modifications, you can use the mouse to change that aspect of the
image perspective.

\ce \{ \ts b Perspective Example \}

\endnode

\node "mrg_xspecsoverunder"
\title "X - Specs Over-Under"
\next "mrg_xspecsinter"
\prev "mrg_perspective"
This will take an image that is interleaved for the X - Specs glasses and
modifies it into the X - Specs Over-Under format.  This transition takes
place entirely in the primary buffer.

\endnode

\node "mrg_xspecsinter"
\title "X - Specs Interleave"
\next "mrg_xspecssep"
\prev "mrg_xspecsoverunder"
This will take an X - Specs image that is in Over-Under format, and changes
it into an interleaved format.  This transition takes place entirely in the
primary buffer.

\endnode

\node "mrg_xspecssep"
\title "X - Specs Seperate"
\next "mrg_roll"
\prev "mrg_xspecsinter"
This will take an interleaved X -Specs image and seperate the two fields into
two new buffers.  You may rename these buffers if you like, or they will be
specified with the current clip numbers.  It is important to remember that
the two new buffers will each need as much memory as the original buffer.

\endnode

\node "mrg_roll"
\title "Roll Image"
\next ""
\prev "mrg_xspecssep"
This tool allows you to roll an image in the horizontal, vertical, or both
directions.  Normal rolling goes down or right, and a negative roll will go
left or up.
