//

//  Description: This program parses a BMP file and writes the

//  necessary image data to a Xilinx COE file.  The COE file

//  can be used to initialize any instantiated BRAM memory!

//

//  There is a significant difference between using binary vs hex COE files.

//  Be sure that you use the radix that will allow you to match the exact data

//  width (i.e. bits/color) of the LCD being used.

//

//  For instance using hex radix in the COE files for the lq057q3dc02 (6

//  bits/color) will result in 38 BRAMs being used to store the data since

//  the hex radix would result in 8 bits of data output to the COE file instead

//  of 6 bits.  There would be 2 extra unused bits of data storage required in

//  the BRAMs.

//

//  If we use binary radix instead we can match the data width of the LCD

//  exactly.  Using binary radix we use only 29 BRAMs.  For the Virtex-II Pro

//  this is a difference of 29*3/136 vs. 38*3/136.  Resulting in a 64% vs. 84%

//  BRAM usage.

//

//  The time required to generate the BRAM source files is also much less when

//  using binary instead of hex for the lq057q3dc02.  Generating the source files

//  with binary radix COE files only takes 5min 45sec per color while a hex

//  radix COE file requires approx 7 minutes.  This is mainly due to Java's

//  ridiculously slow I/O operations.

  //

  //[B  G  R ][B  G  R ][B  G  R ][P  P  P ]

  //The above is how the image data is stored in memory with 'bitmapImageData' referencing address

  //'00'. Each set of brackets represents one pixel.  But then why are there 4 sets of brackets?

  //I said that the image was 3 pixels wide didn't I?  Well, that's true, but the BMP

  //file format pads out all rows to be a multiple of 4 bytes wide.  3pixels x 3bytes/pixel = 9
