[GRASS5] XML fun with --interface-description's...

Eric_G_Miller · June 24, 2001, 9:25am

FYI,
  Been making a little progress using XSL Transforms on the output of

  $ <grass-cmd> --interface-description 1> <grass-cmd>.xml

Anyway, if you're interested http://www.jps.net/egm2/grass/xml

  Note: The "task" thingies uses a little bit of CSS for formatting.
  Apparently Netscrape doesn't handle it well, so you might want to turn
  off stylesheets (looks much better in Mozilla, or any text browser!).

When I figure out a more usable "package", I'll see about adding it to
CVS.

Eric,
the output looks quite nice under galeon.
Maybe the red stars and the attributes of the parameters can
be displayed a little bit more compact.

I'm open to suggestions. Maybe little icons for each of "type",
"required", and "multiple"? I might be able to combine the "default"
and "options" a little too (getting rid of the list altogether). I had
it in tables before which was more compact, but I had left out the
"default" and "options". Having them as table cells was too much, but
maybe I can just squeeze them under the description? I've spent most of
the time fighting with the weird constructs of XSLT and XPATH
languages...

Nah, icons are hard to understand. Maybe colors.

Some table and color options probably help.
I know that XSLT and XPATH are well complicated.
That is why I am still not sure if they are under- or overrated in
the public eye.

Okay, I'm not big on icons either. They're rarely intuitive.

Okay, I've updated to use tables. Finally I found a way to
conditionally separate "flags" vs. parameters with arguments. I kept
having problems with order dependencies... <*sigh*>. I'm in total
agreement about all this XML stuff being way overrated. It'll be useful
in some contexts, but just look how badly something like gnumeric
performs with large spreadsheets. XML wants to be able to load
everything into memory for parsing, but what if your "document" is
256MB? Perhaps the libraries will get better about this...

Anyway, have a look at the new output (baby blue and light grey
colorings...).

looking at this picture , I have being working on this for quite sometime ,
I have being able to use freetype font rendering engine to generate
bitmaps which then i can throw on the screen using raster methods.
More enhancements can be done on this .What say people.

Hi Somesh,

as freetype support is on the wish list for a long time, it would
be excellent to have it in GRASS!

Hi all,

I have found a display/color problem in d.his:

Today I have done some calculation in northern Italy DEM (GLOBE DEM) and
created an aspect map using r.slope.aspect. Unfortunately moire appears at
Garda lake: all pixels have 0.0 aspect as the lake is flat in DEM, but
appear in different gray values in GRASS monitor.

A screenshot is here:
http://www.geog.uni-hannover.de/users/neteler/tmp/monitor

I have made the map using the command:

d.his i=aspect h=red_map

The red_map doesn't cover the entire area, so the lake area is only affected
by "i=aspect".

Any help would be welcome to fix d.his,

Markus

Markus,

I have attached a version of d.his that I modified a while back. I found
that color tables from floating point rasters were reduced to integers,
giving undesirable results.

The version that I have attached has a couple of extra flags (-o) to
overwrite output file if it exists, and bit= to set the bit depth in the
output (i.e. 8=255, 12=4096, etc).

You will have to edit the makefile and change BIN_AGC to BIN_CMD.

that's nearly real-time response! A suggestion: perhaps the "bit" parameter
can be controled by the Xserver color depth? There fill be such a function.

Unfortunately the moire in identical aspect areas is still there.

Anyway, you update will be improving the existing module, will you update
in CVS?

Hi again on d.his,

there is a simple test to see what I mean with "moire patterns":

r.mapcalc map1=44
r.mapcalc map2=100
d.his i=map1 h=map2

I would expect a homogenous color, but there are irregular patterns.

If you use:

d.his i=map1 h=map2 out=his
r.univar his

you will find a range of values although it should be one value overall.
It looks like a precision problem to me.

Markus
