TVARESID: Verb to add slice model residuals directly on TV
INNAME Image name (name)
INCLASS Image name (class)
INSEQ 0.0 9999.0 Image name (seq. #)
INDISK 0.0 9.0 Disk drive #
INVERS 0.0 46655.0 Version # of SL file. 0=>last
IN2VERS 0.0 46655.0 Version # of model. 0 => last
PIXRANGE Min,Max of image intensity
Max <= Min => entire range
BDROP 0.0 9999.0 Drop slice pts from beginning
EDROP 0.0 9999.0 Drop slice pts from end
GRCHAN 0.0 7.0 Graphics channel to use
Use: TVARESID will add a display of the residuals of a slice file and
a model file to a TV graphics plane. It simply plots the
residual data (slice - model) without clearing the graphics
plane or labeling the plot. TVRESID clears the graphics and
labels the plot as well as plotting the residual data.
Usage hint: Start with a TVINIT to clear the TV memory. Then
do a TVSLICE to one graphics plane, TVAMODEL and TVARESID to two
other graphics planes. This allows all three to be seen but in
different colors to aid recognition. When one or more of the
plots overlap additional complementary colors are used. One of
the parts of this display may be replaced with GRCLEAR and a new
TVAMODEL or TVARESID without deleting the other parts. GROFF
will make one part invisible without deleting it.
INNAME......Image name (name). Standard defaults.
INCLASS.....Image name (class). Standard defaults.
INSEQ.......Image name (seq. #). 0 => highest.
INDISK......Disk unit #. 0 => any.
INVERS......Version # of SL file. 0 => highest version #
IN2VERS.....Version # of model file. 0 => last version.
PIXRANGE....Min,Max of Image intensity. 0 => entire range of
the slice (not the image).
BDROP.......No of slice pts to omit from beginning of plot.
EDROP.......No of slice points to omit from end of plot.
Note that these are points in the slice not pixels in
the original image. Use INEXT='SL'; EXTLIST to see how
many points are in the slice.
GRCHAN......TV graphics plane to use. <= 0 -> 1
