[gdal-dev] Tcl bindings for GDAL/OGR.

[Alexandros Stergiakis]

Hello all,

It was about time for Tcl to have its own GDAL/OGR bindings.
That was the main objective of my GSoC2009 project this summer.

A patch against gdal-1.6.1 can be downloaded from here:
http://tcl-map.googlecode.com/files/gdal-1.6.1-tcl_bindings.diff
It introduces all the necessary changes to the source tree to support
Tcl along with the other languages. These bindings are also SWIG generated.

This code is already somehow tested. A demo Tcl application that renders
Raster/Vector GIS files on a Tkzinc canvas can be found here:
http://code.google.com/p/tcl-map/downloads/list
This application doesn't support much at the moment. It renders the most
commonly found Raster band types (no support though for:
"Palette" -  "Cyan" - "Magenta" - "Yellow" - "Black" - "YCbCr_Y" -
"YCbCr_Cb" - "YCbCr_Cr")
and only a few features types: Polygon, Polygon25D and MultiPolygon.

Right now the paths for Tcl include and lib dirs and other compile time
flags are hardcoded in the GNUmakefile (swig/tcl/GNUmakefile), but it
would be better to fix this at some point, so that Tcl's own m4 macros
are called from within GDAL's autoconf scripts to do the job.
