Subject: Help on imaging...


To: All who can help...

I am in need of a image converter.  I deal with a proprietary format that is
generated by
Digital Photogrammetric instrument, also known as Softcopy. The image is a
tiff "base" with
some additions to the header.  As to my understanding, it has an ASCII header
followed by
binary, raw image data. 

Excerts from the documentation sent to me is as follows:

The ASCII header begins with the physical size of the header, followed by
miscellaneous 
information about the ortho data following the header.  Below is an example
of the ASCII 
data contained in a typical ortho file header.

4096 XXXXX_ORTHO
XXXXXXXX Systems International, Inc.
==================================

Byte ordering: big endian

Rows: 710
Cols: 711

North boundary: 2.6321430000000000e+06
South boundary: 2.6179390000000000e+06
East boundary:  5.1104900000000000e+05
West boundary:  4.9682800000000000e+05

Pixel size (ground units): 2.0000000000000000e+01

Input TIN file name:  /optcl/moa10.xyz.tin
Input image file name:  ./100-10.til
------------------------------------------------------------------------------

The before mentioned "4096" represents the file header size in bytes.

Continuing:

Following the ASCII header data is the binary, raw image data.  This data
consists of 
'Rows'x'Cols' bytes of 8 bit pixel data.  This data is arranged by row, with
no 'white space' 
between pixels or rows.

END DOCUMENTATION...

I've been working with images like this for about 2 years.  I've never tried
to write my own 
converter or viewer.  My biggest problem with these images is the size.  They
usually range
from 300-500 mb+ so they eat enormous amounts of disk.

My goal is to get this image into a format like TIFF or COT (Continuous Tone
Image from 
Intergraph Coporation) and the like.

Any suggestions would be greatly appreciated.

If anyone can help with coding or advice please contact me:
