6 unibmpbump - adjust a .bmp image for unibmp2hex processing

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

13 unibmpbump reads a Microsoft Bitmap Graphics (".bmp") graphics image
14 file and, if it appears to be in a known format, converts it for pro‐
15 cessing by unibmp2hex(1).
16 unibmpbump supports the following Device Independent Bitmap (DIB)
18 header byte lengths for input image files:
19 12 The BITMAPCOREHEADER format. This was the original Micro‐
21 soft Windows header format. It has not been encoutered,
22 and was added only as a subset of the formats that appear
23 below.
24 40 The BITMAPINFOHEADER format. This is the format that most
26 graphics creation programs support, and is the header for‐
27 mat that unibmp2hex expects.
28 108 The BITMAPV4HEADER format. This is the format that the
30 Image Magick convert program creates when converting a PNG
31 image to a BMP image using the "-monochrome" option.
32 124 The BITMAPV5HEADER format. This is the format that the
34 Image Magick convert program creates when converting a PNG
35 image to a BMP image without the "-monochrome" option;
36 convert will encode the image as a "grayscale" image, but
37 with only two colors: black and white.
38 unibmpbump is able to read files created by unihex2png that were subse‐
40 quently saved as BMP files, for example by the convert(1) program,
41 which is part of the Image Magick package. Images created by uni‐
42 hex2png(1) are 544 rows high by 560 columns wide. Images created by
43 unihex2bmp(1) are 544 rows high by 576 columns wide. Thus, if the in‐
44 put Bitmap Graphics file is 544 by 560 pixels, unibmpbump assumes that
45 the file was originally a Portable Network Graphics (".png") file cre‐
46 ated by unihex2png and realigns the glyphs so they are positioned as
47 unibmp2hex expects.
48
50 -i Specify an input Bitmaps Graphics (".bmp") file. If no input
51 file is specified, input is taken from stdin. The input file
52 must be either 544 rows by 560 columns (for a file created by
53 unihex2png originally) or 544 rows by 576 columns (for a file
54 created by unihex2bmp originally).
55 -o Specify an output Bitmaps Graphics (".bmp") file. If no output
57 file is specified, output is sent to stdout. The output file
58 will be 544 rows high by 576 columns wide with a 40 byte Device
59 Independent Bitmap (DIB) header, which is the format that
60 unibmp2hex expects.
61 -v, --verbose
63 Verbose output. Print information about the input file on
64 stderr.
65 -V, --version
67 Print the version of unibmpbump and exit.
68
70 Bitmap Graphics (".bmp") input and output files.
