Some image formats, such as ERDAS IMAGINE, BSQ, BIL, BIP, 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, whichthe same name as the image, with the letter w appended.

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 allowas to load the image into the current view, saving the original file image width/height ratio
A)
Sextante NoWorldFile 01.png
B)
Sextante NoWorldFile 02.png

Enabling the option Warp image to fit current view will deform the image to fit the current view
C)
Sextante NoWorldFile 03.png
D)
Sextante NoWorldFile 04.png

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
