== Introduction ==
OpenJUMP allows to save Raster Image Layers to a new file.

=== OpenJUMP before version NB 4397===

Select a Sextante Raster Layer and left click. Choose '''Save Raster Image as Image'''. 
This option allows to save a raster image to a TIFF file

=== OpenJUMP since version NB 4397===
Select a Sextante Raster Layer and left click. Choose '''Save Raster Image as Image'''. 
Depending if selected raster image layer is a single banded or a multiple banded layer there are two option: 
'''Multiple banded raster layer''' 
This option will save a selected multiband raster layer to TIF or to PNG file formats 
[[File:Save_Sextante_raster_02.png|600px]] 
'''Single banded raster layer''' 
This option will save a selected single banded raster layer to ASC, FLT or TIF file formats

Some image formats, such as GeoTIFF, and grids, store the georeferencing information in the header of the image file. Several other image formats (JPG, PNG, BMP, GIF and TIF) store this information in a separate text ASCII file, which has the same name as the image, with the letter w appended.
 
'''Sextante Raster Images''' since OpenJUMP version 4397
 
Loading in OpenJUMP image file with no georeferencing information opens a wizard dialog that allows to create a world file and to load the image into the view.
The default option allows to load the image into the current view, saving the original file image width/height ratio. The coordinates can be changed by the user - in this case width/height image ratio can be modified 
'''''A)''''' 
[[File:Sextante_NoWorldFile_01.png|600px]] 
'''''B)''''' 
[[File:Sextante_NoWorldFile_02.png|600px]] 

Enabling the option ''Warp image to fit current view'' will deform the image to fit the current view 
'''''C)''''' 
[[File:Sextante_NoWorldFile_03.png|600px]] 
'''''D)''''' 
[[File:Sextante_NoWorldFile_04.png|600px]] 
 
In both case a new world file will be created for the loaded image.
To reset the transformation delete the world file and reload the image
 
'''Sextante Raster Images''' before OpenJUMP version 4397
 
Loading in OpenJUMP image file with no georeferencing information opens a wizard dialog that allows only to deform the image to current view
 

'''Images loaded via Open File wizard'''
 
The image will be automatically loaded into the view, proportionally to its height/width proportions. The upper left corner of the image will be anchored to coordinates (0,0)
