NAME

       unibmpbump - adjust a .bmp image for unibmp2hex processing

SYNOPSIS

       unibmpbump [-iinput-file.bmp] [-ooutput-file.bmp] [-v|--verbose] [-V|--version]

DESCRIPTION

       unibmpbump  reads  a  Microsoft  Bitmap  Graphics  (".bmp") graphics image file and, if it
       appears to be in a known format, converts it for processing by unibmp2hex(1).

       unibmpbump supports the following Device Independent Bitmap (DIB) header byte lengths  for
       input image files:

              12    The  BITMAPCOREHEADER format.  This was the original Microsoft Windows header
                    format.  It has not been encoutered, and was added only as a  subset  of  the
                    formats that appear below.

              40    The  BITMAPINFOHEADER format.  This is the format that most graphics creation
                    programs support, and is the header format that unibmp2hex expects.

              108   The BITMAPV4HEADER format.  This is the format that the Image Magick  convert
                    program  creates  when  converting  a  PNG  image  to  a  BMP image using the
                    "-monochrome" option.

              124   The BITMAPV5HEADER format.  This is the format that the Image Magick  convert
                    program  creates  when  converting  a  PNG  image  to a BMP image without the
                    "-monochrome" option; convert will encode the image as a  "grayscale"  image,
                    but with only two colors: black and white.

       unibmpbump is able to read files created by unihex2png that were subsequently saved as BMP
       files, for example by the convert(1) program, which is part of the Image  Magick  package.
       Images  created by unihex2png(1) are 544 rows high by 560 columns wide.  Images created by
       unihex2bmp(1) are 544 rows high by 576 columns wide.  Thus, if the input  Bitmap  Graphics
       file  is  544  by  560  pixels, unibmpbump assumes that the file was originally a Portable
       Network Graphics (".png") file created by unihex2png and realigns the glyphs so  they  are
       positioned as unibmp2hex expects.

OPTIONS

       -i    Specify  an  input  Bitmaps  Graphics (".bmp") file.  If no input file is specified,
             input is taken from stdin.  The input file must be either 544 rows  by  560  columns
             (for a file created by unihex2png originally) or 544 rows by 576 columns (for a file
             created by unihex2bmp originally).

       -o    Specify an output Bitmaps Graphics (".bmp") file.  If no output file  is  specified,
             output is sent to stdout.  The output file will be 544 rows high by 576 columns wide
             with a 40 byte Device Independent Bitmap (DIB) header,  which  is  the  format  that
             unibmp2hex expects.

       -v, --verbose
             Verbose output.  Print information about the input file on stderr.

       -V, --version
             Print the version of unibmpbump and exit.

FILES

       Bitmap Graphics (".bmp") input and output files.
