Hi everyone.
Lets see if someone can tell me what could be wrong.
I am working with:
MapServer version 4.4.0 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER INPUT=EPPL7 INPUT=GDAL INPUT=SHAPEFILE
I am using java servlets.
when I use shapefiles :usa1.map it works but when I want to include a tif file it doesn't work: usa3.map, nitelti020l.tif
The instructions I use are:
for the first case that works:
...
mapObj map = new mapObj("/mypath/usa1.map");
imageObj img = map.draw();
img.save("/mypath/usa1.png", map);
...
out.println("<BR><IMG SRC=http://webbrowserpath/usa1.png>");
For the second case with raster that doesn't work:
...
mapObj map = new mapObj("/mypath/usa3.map");
imageObj img = map.draw();
img.save("/mypath/usa3.png", map);
...
out.println("<BR><IMG SRC=http://webbrowserpath/usa3.png>");
And here are the mapfiles:
