NAME
imagsize - figure out the image size of BMP, GIF, JPEG, PBM, PGM, PPM,
PNG, TIFF, XBM, and XPM files
SYNOPSIS
imagsize [-f file_list] [-h(elp)] [-n(ormal_format)] [-p(ipe)] [-x(win-
dow_format)] [-v(erbose)] [-w(eb_format)] file...
DESCRIPTION
imagsize figures out the dimensions of BMP, GIF, JPEG, PBM, PGM, PPM,
PNG, TIFF, XBM, and XPM files. It also determines a few other numbers
(bit depth, quality estimates, etc.) for a subset of the file formats.
It's a minimal program for situations where you don't want to install
(or use) a large image manipulation package such as ImageMagick.
OPTIONS
-h Print help and quit.
-n Print output in normal format. This is the default.
-w Print output in a format suitable for including in an HTML-based
Web page.
-x Print outout in a format suitable for including in command lines
of X-Window program commands
-f filelist
Read the names of files to be processed from the specified file.
-p Read the names of files to be processed from stdin.
-v Verbose output. Print results for non-image files, which are
normally skipped entirely.
NOTES
The -f and -p options can be used simultaneously with filenames speci-
fied on the command line.
HISTORY
The imagsize program is heavily derived from Jef Poskanzer's excellent
image_size program. The JPEG quality estimates (derived from Allen
Hessenflow's jpegdump program) and various output format options were
added by Brian Lindholm.
