NAME
infotopam - convert Amiga .info icons to PAM

SYNOPSIS
infotopam [-forcecolor] [-numcolors numcolors] [-selected] [index color ...] [filename]

Minimum unique abbreviation of option is acceptable. You may use double hyphens instead
of single hyphen to denote options. You may use white space in place of the equals sign
to separate an option name from its value.

EXAMPLES
By default, infotopam converts the first icon in a .info file:

infotopam amiga.info > amiga.first.pam

Use the -selected option to convert the second icon in a .info file. Here infotopam reads
from Standard Input:

infotopam -selected < amiga.info > amiga.second.pam

Use the -forcecolor option to force color conversion for a 1 bit-plane .info file:

infotopam -forcecolor bw.info > bw.pam

Use -numcolors to override colors for indexes 0 and 3. Notice the two ways to specify the
color:

infotopam -numcolors 2 0 green 3 #FF0000 icon.info > icon.pam

Since Amiga monitors do not use square pixels, some icons may appear squished. Filtering
the output through pamscale can fix this:

infotopam squish.info | pamtopnm | pamscale -yscale 1.7 > normal.pnm

DESCRIPTION
This program is part of Netpbm(1).

infotopam converts an Amiga .info (icon) file to a PAM image. infotopam reads a .info
file from filename, or from Standard Input if you do not specify a file name, and writes
the converted PAM image to Standard Output.

infotopam currently handles 1 and 2 bit-plane icons. If the .info icon only has 1 bit-
plane, infotopam generates a bitmap (black&white) PAM image; otherwise it generates a
color PAM image. You can force infotopam to convert 1 bit-plane images to color PAM
images by using the -forcecolor option.

OPTIONS
-forcecolor

Forces infotopam to convert 1 bit-plane icons to color PAM
images instead of bitmap PAM images. infotopam uses the index 2
color for black and the index 1 color for white (more on this
below).

-numcolors numcolors

Tells infotopam how many colors to override. Pixels in the
Amiga .info files are assigned an index value rather than a specific color.
The standard colors for a 2 bit-plane icon are:

Index 0: Blue (00, 55, AA)
Index 1: White (FF, FF, FF)
Index 2: Black (00, 00, 20)
Index 3: Orange (FF, 8A, 00)

To override the colors, first specify how many colors to override using
-numcolors, then specify an (index color) pair for each color
you want to override, where index is a value from 0 to 3 and
color the new color for that index. Specify color as
described for the ppm_parsecolor() argument <libppm.html#colorname> .

-selected

Tells infotopam to convert the selected (second) icon instead of
the normal (first) icon. Each Amiga .info icon file contains two icon
images. The first image is the normal, unselected icon, and the second
image is the selected icon. By default infotopam converts the first
icon. You can tell infotopam to convert the second icon by using the
-selected option.

All options can be abbreviated to their shortest unique prefix.
