Open Raster Files
Old Raster framework
To open Raster Files click on Menubar>Layer>Add Image Layer (ecw deactivated) function or Menubar>Open Files..
Currently OpenJump can read GIF PNG JPG JPEG TIF and TIFF. ECW is actually deactivated. Other format can be supported using external files:
Reading additional image formats
Reading ECW image files
Reading MrSID image files
Reading JPEG2000 image files
New Raster framework (Sextante compatible)
Save Raster Files
OpenJUMp can save a project view to raster files.
To save the view to Raster file choose Menubar>File>Save View as Image...
Currently only PNG and JPG are supported.
OpenJUMP can save to georeferenced file with world file. To save to georeferenced file make sure that the option Write World File is enabled.
The Fence function in the Save as Image window allows to save as Image the part of project within a fence.
Raster Transparency
Basic OpenJUMP setup does not have support for Raster trasparency. However, if image files are loaded with "Sextante Raster Image" then this function is available. (This function has been copied from Pirols Raster Image Plugin=
Georeference Raster
See How to georeference rasters page
Raster Reprojection
Currently OpenJUMP does not support reprojection of Raster files.
You can use FWTools: a set of tools for Linux and Windowsto which can view/edit/save several raster and vector file formats.
Based on GDAL and OGR libraries, it includes the viewer OpenEV that provides access to the files with a graphic interface (see also GDAL Raster Formats and OGR Vector Format. There is also a tool to reproject raster files
See also [http://www.fsdeveloper.com/wiki/index.php?title=Working_with_FwTools_and_GeoTIFF_files

Some usefull information about raster reprojection software can be found in Leszek Pawlowicz's post Reprojecting Raster Imagery I and Reprojecting Raster Imagery II - ERDAS Viewfinder
Some usefull software for local or national coordinate raster reprojection: Traspunto (Gauss-Boaga, datum Roma40 - UTM, datum ED50 - UTM, datum WGS84)
Raster Filters
Image Plugin Enhancement, from Lenka Ferkova and Jan Kucharczyk, allows some filter operations on Image (edge, blur, inverse). User can define their own kernel filter.
