CS 686

PROJECT 1		               Due Date: 7pm Thursday 08 Sep 2005

     The purpose of this project is to acquaint students with some common
graphics file-formats and image-compression techniques, and to provide an
initial encounter with systems programming issues involved in the display
of SVGA graphic images in a contemporary Linux environment.
 

                        PROJECT STATEMENT

     Design an application program named 'bmpphoto.cpp' that will display
the scanned color photograph, stored in a file (named 'fwright.bmp') that
you can download from our course website.  (For this you can just imitate 
the same basic steps as in our 'pcxphoto.cpp' demo-program, although some
significant changes will be needed to accommodate the larger-sized image,
the different layout of .bmp file-data, plus absence of RLE compression.)  
You can use 'google' to find detailed information about .bmp file-format. 
(The photograph you will display shows the interior of 'Hollyhock House',
located at 4800 Hollywood Boulevard in Los Angeles, designed by acclaimed
architect Frank Lloyd Wright in 1917 and donated to the city in 1927; you
can find more information at <http://www.hollyhockhouse.net>). 


                          EXTRA CREDIT   

     Write an application program (named 'bmp2pcx.cpp') that will convert 
the 'fwright.bmp' image-file into a .pcx file (called 'fwright.pcx'), and
submit a modification of our 'pcxphoto.cpp' application that will display
your .pcx version of this remarkable image.  (You will see a reduction in
the file's size as you convert from .bmp to .pxe format, a result of your 
using RLE data-compression.) 


			 WHAT TO SUBMIT

     Copy your program source-files (including your header-files) to your
CS 686 '/submit' directory, along with your compiled 'executables'.  This
will enable the Instructor to perform testing of your program-code.  Also
turn in to the Instructor's mailbox (in HRN-208) a paper printout of each 
source-file you authored.  This will enable the instructor to easily read
your code and add handwritten comments that can be returned to you.      

   Turn in printout of 'bmpphoto.cpp' (for basic project-requirements)
   Turn in printout of 'bmp2pcx.cpp' and 'pcxphoto.cpp' (extra credit)

  NOTE: Please use our 'ljpages.cpp' utility to print your source files!
