RLETOPAINT(1) 1 (Month X, YYYY) RLETOPAINT(1)
NAME
rletopaint - convert an RLE file to MacPaint format using
dithering
SYNOPSIS
rletopaint [ -l ] [ -r ] [ -g [ gamma ] ] [ -o outfile.paint
] [ infile ]
DESCRIPTION
Rletopaint converts a file from RLE(5) format to MacPaint
format. The program uses dithering to convert from a full
24 bit color image to a bitmapped image. If the RLE file is
larger than a MacPaint image (576x720) it is cropped to fit.
Because MacPaint files have their coordinate origin in the
upper left instead of the lower left, the RLE file should be
piped through rleflip(1)-v before rletopaint.
The resulting file can be downloaded to a Macintosh in
binary mode, and should be given a type of PNTG and a
creator of MPNT, so it will be recognized as a MacPaint
file.
OPTIONS
-l Use a linear map in the conversion from 24 bits to
bitmapped output.
-g [ gamma ]
Use a gamma map of gamma (gamma is 2.0 if not
specified).
-r Invert the sense of the output pixels (white on black
instead of black on white). For normal images, you
probably want this flag.
