Information about the .coo (coo) file type

Below is all the information we have available on file about the .coo (coo) file type.

.coo
(Bounding) Coordinates file. Contains information to geo-code an image (showing where the image exists in Cartesian space.)

.coo files are generated and used by AutoCAD, and are also known as cookie files where each cookie file will relate to a single raster file.

A .coo file is a text editable file, and contains the bounding coordinates for a geocoded image/raster file in Cartesian space (for use when for example loading into a mapping system.)

A coo file contains 9 lines, such as:

File name: 5154.tif
File type: TIFF B&W PACKBITS
LLX:       96000
LLY:       133000
URX:       100000
URY:       136000
Resolution 0.2
Columns    20000
Lines      15000

Each line provides the following information:

Line 1: File name The name of the image/raster file. In the example above the image file is a .tif file but it could be other types of image file or a .dwg file.
Line 2: File type  
Line 3: LLX X-Coordinate (or Easting) of the pixel at the lower left corner.
Line 4: LLY Y-Coordinate (or Northing) of the pixel at the lower left corner.
Line 5: URX X-Coordinate (or Easting) of the pixel at the upper right corner.
Line 6: URY Y-Coordinate (or Northing) of the pixel at the upper right corner.
Line 7: Resolution Scale, indicating the effective height/width of each pixel in physical units. In the example above, each pixel corresponds to an area of 0.2m2
Line 8: Columns The width of the image in pixels.
Line 9: Lines The height of the image in pixels.

Where this is available we would like to include file format information on .coo files, as well as information on how to view or open files of type .coo. If you know of any information which we have missed then please let us know.
