TVRESID: Verb to display 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
LTYPE -410.0 410.0 Type of labeling: 1 border,
2 no ticks, 3 standard, 4 rel
to center, 5 rel to subim cen
6 map pixels, 7-10 as 3-6 but
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: TVRESID will display the residuals of a slice and a model file
directly to TV graphics plane without going through a plot file.
It erases the specified graphics plane, labels the plot, and
then draws the slice residual (slice - model) data. TVARESID
draws slice residuals without the erasure and labeling.
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.
LTYPE.......Labelling type, see HELP LTYPE for details:
1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
relative to ref. pixel, 5 or 9 = relative to subimage
(BLC, TRC) center, 6 or 10 = pixels. 7-10 all labels
other than tick numbers and axis type are omitted.
Add n * 100 to alter the metric scaling.
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
