Hi John, I just tested the csv2shp sample using the createFeatureType method rather than DataUtilities and it worked for me (don't you hate it when people say that ?). The only problem I found was that it didn't deal with empty lines in the input file, but that doesn't sound like the error that yo

Hello, It certainly is true that a lot less work is put into the docs than into the code. This is a syndrome that affects most projects and the root cause is that good docs take a long time to write, test and edit but generally nobody wants to fund this work. As a result pretty much all of the eff

Brian Ghigiarelli, I'm also finding it very difficult to learn GeoTools. The API is not easy and the documentation is incomplete and confusing. To create a single point on the map with an icon is very complex! As a user will be able to learn alone without good documentation it needs to use G

Yes; a couple of ways. - Draw the image as geotools is drawing into it... this is what uDig does. - Get a volatile image and use that to draw into. It is tricky Java 2D programming (because you need to redraw if windows are moved in front of your image) but it is effective. Jody On 07/05/2010,

As far as I know, default geotools drawing mode is to draw on offline buffer and then render this buffer to the screen. On the opposing side, OpenJump (for example) draws everythink it can draw immediately. This give user the feeling of more responsive interface, because hey - something is going
