ICV(1)
SYNOPSIS
icv [-h] [-i file] [--input-format fmt] [-o file] [--output-format fmt] [-w width] [input_file] [output_file]
DESCRIPTION
icv is a tool to convert images to and from a variety of image formats. Currently support formats include:
| Format | Extension |
|---|---|
PIX - pixel sequence of R/G/B values stored as unsigned chars. |
pix |
Double PIX - double precision pixel sequence |
dpix |
Portable Network Graphics |
png |
PPM - "lowest common denominator" Netbpm color iamge format |
ppm |
BW - black and white image data |
bw |
(TODO) Utah Raster Toolkit Run-Length Encoded (RLE) |
rle |
OPTIONS
File types will be deduced unless explicitly specfied with the input-format and/or output-format options. For file types like PIX that do not encode dimensional information, icv will attempt to guess the image size based on various assumptions (a square image, known sizes for image displays, paper sizes at various dots-per-inch, etc.). If the users does know the correct image width and height, they may be specified with the w and n options.
- -h, --help
-
Print help and exit.
- -i file, --input file
-
Specify an input file. If none is specified, the first non-option-related argument will be used as the input file name.
- -o file, --output file
-
Specify an input file. If none is specified, the second non-option-related argument will be used as the output file name.
- -w , --width
-
Specify the width of the input image. Useful for file types such as PIX that do not encode explicit size information.
- -n , --height
-
Specify the height of the input image. Useful for file types such as PIX that do not encode explicit size information.
- --input-format fmt
-
Explicitly specify input file format.
- --output-format fmt
-
Explicitly specify output file format.
