[Gvsig_english] RES: Raster support on GVSIG

Edson,

I don't use gvSIG Mobile. There are manuals on the web.

>From my understanding you have to install a plugin into gvSIG Desktop,
which is used to generate a 'project' file that is used by gvSIG Mobile.

Dear all,

I also need to display those images on gvSIG mobile. I uploaded the
image with the jpw and rmf files that were generated by gvSIG Desktop
and added a new layer on the mobile pointing to the jpg image, but it
was not put on the correct position. The Desktop works fine, but the
mobile do not. Does the mobile version need more metadata files or
something?

Regards,

Edson,

The latest version of gvSIG is 1.9. Spanish manuals are available at
http://www.gvsig.org and English versions are being prepared.

The manual for the earlier version, version 1.1.2, is available at
http://www.gvsig.org/web/docusr/manuales-en and discusses the basic
concepts.

gvSIG can display and manipulate jpeg, jpg, gif, png, bmp and svg (+
more). Although some require header files containing georeferencing data
to be displayed correctly.

gvSIG can also connect to GeoDB, WCS, ArcIMS, WMS, Annotation and WFS
internet services that can contain image data.

Usually JPG or PNG files require header files that contain the
coordinates of the upper left corner and the pixel size. A typical
example can be seen below.

For a file called "JPG_Image.jpg" you would have a corresponding file
called "JPG_Image.jpgw". gvSIG also creates an "aux.xml" and "rmf" file
with the same data.

The content of the different files look like this...

*JPGW*
