tkimggdal is a photo image format handler using the Geospatial Data Abstraction Library (GDAL). GDAL is a translator library for raster geospatial data formats released by the Open Source Geospatial Foundation (see ).

The two main features of this handler are:

  • Provides access to all the raster formats supported by the GDAL library which includes standard types of images such as TIFF, PNG, GIF, JPG as well as popular GIS formats such as ECW (ERMapper Compressed Wavelets) and MrSID (Multi-resolution Seamless Image Database). For a full list checkout .
  • Unlike Tk's builtin handlers and those in the Img extension, it is very quick at reading subsections of very large image files because the GDAL library doesn't read the entire image into memory.

wgm 24Jan07 -- Version 0.5 has been released and is now available at . The release includes the Critcl 2 source file and binary packages for i686 Linux and Windows. To build or use the binary packages you will need to install the FWTools package (see ). This version still only supports reading images from file.

LV I always wondered why someone hadn't collected image format handlers up and made them generally available. I thought that Img was going to do that, but there doesn't seem to have been new formats added there in a while.
