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.
