Release Notes Version 4.00
Part of HEAsoft 5.1 - July 26, 2001
Changes in version 4.00
- Tcl interface
- New /xtk device provides GUI facilities
- Multiple image maps (up to nine) may be loaded in memory at once
- Real maps are fully supported, allowing negative and null values as well
- Overlayed contours are automatically transformed to underlying coordinates
New commands
- map -
Image map information and manipulation

Calculate background levels (mainly for internal use by contour/statistic)
- gencolor -
Extracts red, green, and blue ranges from event file, then spawns
external tool, mkcolor, to generate color image, and displays
- draw -
Draw shapes (mainly for internal use)
- pimage -
Plot image (mainly for internal use by display)
- pcontour -
Plot contours (mainly for internal use by contour)
New options
- colors
- null -
Specify color index with which to draw null pixels
- contour
- mapid -
Plot contours for specified map
- nocoortrf -
Disable automatic coordinate transformation on overlay
- statistic -
Contour based on background statistics
- sigma_levels -
Contour based on sigma levels based on background statistics
- mult_levels -
Contour based on multiples of background
- background -
Specify value for background
- cpd
- leaveopen -
Leave /xtk device open when changing device (mainly for internal use)
- display
- mapid -
Plot image for specified map
- hotspot
- angle -
Specify angle of text
- just -
Specify justification of text
- iminfo
- widscale -
Specify width of image scale bar
- label
- clip -
Turn on clipping, so labels outside viewport aren't plotted
- text -
Specify label text with qualifier
- levels
- histo -
Calculate levels based on histogram equalization
- linear -
Calculate levels based on linear scaling
- log -
Calculate levels based on logarithmic scaling
- sqrt -
Calculate levels based on square-root scaling
- minlevel -
Set minimum level in calculation
- maxlevel -
Set maximum level in calculation
- list -
Enter levels as Tcl list, e.g. {1 2 3 4} or "1 2 3 4"
- read_image
- mapid -
Read image into specified map
- tcol -
Set time column
- smooth
- real -
Retain real values after smoothing instead of truncating to integers
- sosta
- bgregion -
Specify background with region
- srcregion -
Specify source with region
- surface
- xmin,xmax,ymin,ymax,refresh -
Added to allow zooming in on /xtk device (mainly for internal use)
- viewport
- switch -
In combination with number, selects the viewport to which
all coordinate retrieval refers
- info -
Print information on the contents of displayed viewports
- vplabel
- text -
Specify label text with qualifier
- write_image
- mapid -
Write specified map to a file
- nonull -
Zero out null values in output image
Altered commands and options
- alias
- (all options removed) -
Only supported syntax: alias <newcmd> <oldcmd>
- centroid
- plot -
Removed as new default is to plot centroid location
- contour
- coordsaved -
Removed as coordinate transformation is now automatic on overlay.
Old
procedure: read;disp;save;read;cont/over/coordsaved
New equivalent:
read;disp;save;read;cont/over
- extract
- regionfile=@filename -
When preceded by @, filename is assumed to be list of regionfiles to perform color extraction on
- info->iminfo
- (name change) -
Tcl's info command conflicts, so ximage info command is now iminfo
- keywords (aka ?)
- (modified behavior) -
Now takes user to keywords prompt, like help
- levels
- ldshow -
Removed as show and ldshow now correspond to same levels
- pixel_to_radec
- plot -
Removed as new default is to plot specified location
- sosta
- cursor -
Removed - Now default
- loop -
Removed
- no_of_boxes -
Removed
- size_of_boxes -
Removed
