Synopsis

A commandline program that creates a waveform representation of a PCM wav file and stores that as a PNG image.

Usage

waveformgen OPTION...

    -b, --background=COLOR     background color
    -f, --foreground=COLOR     foreground color
    -h, --height=NUM           image height in pixels
    -i, --infile=PATH          path to PCM WAV file (input)
    -o, --outfile=PATH         path to PNG image file (output)
    -v, --verbose              prints some diagnostic output
    -w, --width=NUM            image width in pixels
    -?, --help                 Give this help list
        --usage                Give a short usage message
    -V, --version              Print program version

Color specifiers

Colors are in RGB space with r, g, b having possible values from 0 (zero) to
65535 (0x0000 to 0xffff) each. A color specification is a hexadecimal string
comprising three groups of four hexadecimal digits each, in the order
rrrrggggbbbb. You always need to specify four hex digits per group, including
any leading zeros. Example:

For the background color

r=0x1a2b
g=0x004d
b=0x5e00

the commandline argument is

-b 1a2b004d5e00

or

--background=1a2b004d5e00

Target environment

Mainly designed for unsupervised operation, for example as part of a cron job or called from a web service.

To build from source

Apologies, there are no GNU build system parts (makefiles, configure script etc). Will be added later.
