ppmtowinicon(1) General Commands Manual ppmtowinicon(1)NAME
ppmtowinicon - convert 1 or more portable pixmaps into a Windows .ico file
SYNOPSIS
ppmtowinicon [-andpgms] [-output output.ico] [ppmfiles...]
DESCRIPTION
Reads one or more portable pixmaps as input. Produces a Microsoft Windows .ico file as output.
A Windows icon contains 1 or more images, at different resolutions and color depths.
Microsoft recommends including at least the following formats in each icon (size and bits-per-pixel):
16 x 16 - 4 bpp
32 x 32 - 4 bpp
48 x 48 - 8 bpp
Default I/O is STDIN/STDOUT.
OPTIONS -andpgms
If this option is given, every second file is read as an "and mask" to be used by windows for transparency data for the previous
image. (These are set to fully opaque by default). The and mask is a PGM image, where any pixel with maxval intensity means opaque
and any other pixel means not opaque. Note that as with all Netpbm programs, you may use a PBM file here and it will be used as if
it were the equivalent PGM.
The and mask is like an alpha mask, except for what it signifies in the "not opaque" areas. In the usual case, the foreground image
is black in those areas, and in that case the areas are fully transparent -- the background shows through the icon. But in general,
a not opaque pixel signifies that the background and foreground should be merged as follows: The intensities of the color components
in the forgeground and background are represented as binary numbers, then corresponding bits of the background and foreground inten-
sities are exlusive-or'ed together. So there is a sort of reverse video effect.
-output output.ico
File to write. By default, the icon is written to stdout.

icotool - Convert and create Win32 icon and cursor files
SYNOPSIS
icotool [OPTION]... [FILE]...
DESCRIPTION
This manual page document describes the icotool command.
The icotool program converts and creates icon (.ico) and cursor (.cur) files. At the moment icons can only be created from and extracted
into PNG files. This is done using libpng.
Icon and cursor files are used mainly on the Microsoft Windows(R) platform. Each icons or cursors file may contain multiple images of vari-
ous resolutions and with different number of colors. Cursor files differ from icon files in that they also contain information about the
hotspot of each image.
Recent versions of Microsoft's Internet Explorer use icons for small site logotypes. The browser fetches a file called favicon.ico from a
web site, and uses the images in this file to represent the site in menus and site lists. (This file is placed in the web site's root
directory, like any other file.) Browsers like Galeon have copied this behaviour and now also fetches .ico files and use them for site
logotypes.
As each icon or cursor file may contains multiple images of different dimensions and depth, a conversion may result in multiple PNG files
being created. Correspondingly, multiple PNG files can be specified when creating an icon/cursor file.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-').
-x, --extract
This option tells icotool that images from all icon/cursor files given on the command line are to be extracted. Filter options (see
below) can be used to control what images that will be extracted.
-l, --list
This options tells icotool that images in all given icon/cursor files are to be listed. The output will look something like this:
--icon --index=1 --width=16 --height=16 --bit-depth=4 --palette-size=16
--icon --index=2 --width=32 --height=32 --bit-depth=8 --palette-size=256
-c, --create
This options tells icotool to create an icon/cursor file using all the PNG files given on the command line, in the order they were
specified. The number of bits per pixel used in the icon/cursor file will depend on the number of colors used in the PNG file. (If
the PNG image has an indexed palette, it doesn't necessarily mean that the same palette will be used in the created icon/cursor
file.)
-i, --index=N
When listing or extracing files, this options tell icotool to list or extract only the N'th image in each file. The first image has
index 1.
This option has no effect in create mode.
-w, --width=PIXELS
Similar to --index, but this option allows the image width to be matched instead. This option has no effect in create mode.
-h, --height=PIXELS
Similar to --index, but this option allows the image height to be matched instead. This option has no effect in create mode.
-b, --bit-depth=COUNT
Similar to --index, but this option allows the number of bits per pixel in the image to be matched instead. Valid values are 1, 2,
4, 8, 16, 24 and 32.
In create mode, this option will allow you to specify a minimum bit depth for images in the icon file.
-p, --palette-size=PIXELS
Similar to --index, but this option allows the number of colors in the image palette to be matched instead. Images with 24 or 32
bits in icon/cursor files do not have a palette, and will therefore have a palette size equal to 0.
This option has no effect in create mode.
-X, --hotspot-x=COORD
Similar to --index, but this option allows the x-coordinate of the hotspot to be matched. This option only has effect on cursor
files.
In create mode, this can be used to specify the hotspot x-coordinate.
-Y, --hotspot-y=COORD
Similar to --index, but this option allows the y-coordinate of the hotspot to be matched. This option only has effect on cursor
files.
In create mode, this can be used to specify the hotspot y-coordinate.
--icon This option specifies that only icon files are to be listed or extracted. In create mode, this option can be used to specify that
an icon (instead of a cursor) is to be created. (This is default in create mode.)
--cursor
This option specifies that only cursor files are to be listed or extracted. In create mode, this can be used to specify that a cur-
sor (instead of an icon) is to be created.
-t, --alpha-threshold=LEVEL
Specifies the maximal alpha level in the PNG image for portions which shall become transparent in the icon created. The default
value is 127. This is only used when creating icon files.
-o, --output=PATH
In extract mode, this option specifies a directory where extracted files are to be created. If PATH does not exist, it is assumed
that it refers to a non-existing file instead. The first image matched will be extracted to the file with that name.
In create mode, this option specified the name of the output file. The default is to write the binary data to standard out (which
icotool will refuse if standard out is the terminal).
If PATH is `-', then all output will be printed to standard out.
This option has no effect in list mode.
--help Show summary of options.
--version
Output version information and exit.

--icon --index=3 --width=48 --height=48 --bit-depth=4 --palette-size=16
--icon --index=4 --width=16 --height=16 --bit-depth=8 --palette-size=256
--icon --index=5 --width=32 --height=32 --bit-depth=8 --palette-size=256
--icon --index=6 --width=48 --height=48 --bit-depth=8 --palette-size=256
List only 16-color images in `demo.ico':
$ icotool -l --palette-size=16 demo.ico
--icon --index=1 --width=16 --height=16 --bit-depth=4 --palette-size=16
--icon --index=2 --width=32 --height=32 --bit-depth=4 --palette-size=16
--icon --index=3 --width=48 --height=48 --bit-depth=4 --palette-size=16
Extract all images to current directory, naming the destination files `demo.ico_I_WxHxD.xpm':
$ icotool -x -o . demo.ico
$ ls *.png
demo_1_16x16x4.png demo_3_48x48x4.png demo_5_32x32x8.png
demo_2_32x32x4.png demo_4_16x16x8.png demo_6_48x48x8.png
Extract all 256-color icon images in all .ico files in the current directory, placing the extracted images in `img/'
$ icotool -x -o img/ -p 256 *.ico
Create an icon named `favicon.ico' with two images:
$ icotool -c -o favicon.ico mysite_32x32.png mysite_64x64.png
