A few enhancements in functionality have also occured:
- blockmean
- was given a new option -S to report the
sum of z-values inside a block rather than their average [Default].
- grdimage
- has a new option -T which will plot an image
without any interpolation. This is useful for categorical data where
interpolation is undefined.
- grdinfo
- was given a new option -F to report the
domain and increment in world mapping format.
- grdview
- has the same new -T option as grdimage .
- psimage
- was given new options -E to specify image resolution
in dots pr inch (instead of image size), and -F to draw a rectangular
frame around the image.
- psxy/psxyz
- can accept an optional %font appended to the -Sl
option which will select a particular font [Default is the anotation font].
The program will now also accept the -C option with
multisegment polygon files (-M). Then, polygon colors are assigned
by looking for a -Zval string in each multisegment header; this
val is then used to select the color via cpt lookup.
Finally, four Japanese font names were added to the list of fonts that
GMT recognizes (see Appendix F). However, like all other fonts, you need to have
the fonts installed on your system or printer to actually use them.
