Hi Michael,
just a couple of issues and proposals for further discussions:
- Proposal 1 -
Move "Toogle visibility" to the bottom of menu
In sextante raster image menu the tool "Toogle visibility" is located at the
top of the menu. I experience that if I click on a Sextante visible file on the
layer list, this tool inadvertently actives itself and the file becomes not
visible.
Can we move this tool at the bottom of the popup menu? It would be more
pratical and similar to the other "Toogle visibility" tool in vector file popup
menu.
I did this on my prebuild version of OJ only modifying
LoadSextanteRasterImagePlugIn.
- Proposal 2-
x,y max, min can be useful in sometimes, but I image that an extra menu where
people can write the worldfile od of the loaded file would be better. This
could be useful to set position of the file and any possible x,y rotation (see
hidden tool)
- Hidden Tool -
Using "Warp image to fence"
This is an hidden and useful tool in ex-pirol functionalities.
Actually, using this tool together with Edgar's CTS tool, I can make reasonable
re-projections of raster files. The only limit is that the "reprojection" works
only with y and x translations and no rotations. I
In many case it is not useful, for instance reproject from geografic to
cartesian where there is always a rotation of the axis.
But in other situation is extremely useful within cartesian reprojections: it
works very well when I have to reproject between WGS84 and any Italian local
CRS (Gauss-Boaga, etc) which I cam configure with Edgar's CTS, even better than
standard GIS like GvSIg.
Within the limitations of "rotation", it is possible also to "georeference"
raster files. In this case it requires the usage of Warping tools in stead of
CTS.
Mohammed, this could be a base to study a "reproject" and "georeferecing" tool
for Openjump which do not invoke other libraries except java ones (no gdal or
similar) and using only embedded libs.
I can write down more details about this hidden tool if needed.
- bug or strange behavior-
in Sextante popup menu there is a "Save raster to image" tool. This tool has a
random strange behaviour:
1) using on any color image,
It works fine and the saved file can be reopen with no problems.
2) using on a TIF file black and white file, where white is a NO-DATA area.
it saves the file as a negative. When I try to reload the saved file, it is not
displayed.
3) Using on a grid file (tested on TIF or ASC). The file is saved with 0 byte
dimension and
It shows this error message:

_____________________________________________________
Point 1 is probably the heritage of original Pirol raster tool. But point 2 and
3 came out probably when raster pirol was extended to other image format files
(grid etc).
It would be interesting to correct if possible.
In all the 3 case, under Ubuntu, when I save the file it shown the message on
bottom bar "file not found", the TFW file is correctly saved.

Peppe
