PNGINFO(1) General Commands Manual PNGINFO(1)
NAME
pnginfo - display information on the PNG files named
SYNOPSIS
pnginfo [-t] [-d] [-D] <filenames>
DESCRIPTION
This command dumps information about the PNG files named on the command line. This command's output is based on the output of the tiffinfo
command, which is part of the libtiff distribution. Each line output by the command represents a value that has been set within the PNG
file.
The -t command line option forces pnginfo to use libtiff tiffinfo style lables, instead of the more relevant png names. The -d command line
option dumps the bitmap contained by the image to standard out, whilst the -D command merely checks that the image bitmap could be
extracted from the file. If nothing is reported by -D, then there was no error.
The format for the output bitmaps is hexadecimal, with each pixel presented as a triple -- for instance [red green blue]. This means that
paletted images et cetera will have their bitmaps expanded before display.
RETURNS
Nothing.
