iinfo - Extracts and displays image text data


NAME

    iinfo - Extracts and displays image text data


DOWNLOAD

iinfo


SYNOPSIS

    iinfo image
    iinfo -f fieldname image


DESCRIPTION

iinfo takes an image file as an argument and tries to read its meta text data. Many image file formats allow for additional information to be attached to the otherwise binary image data.


EXAMPLES

  $ iinfo dcsf002002.jpg
    DateTime ................... 2002:01:20 10:38:02
    file_media_type ............ image/jpeg
    CompressedBitsPerPixel ..... 20/10
    ExposureBiasValue .......... 0/100
    ExposureTime ............... 10/800
    ISOSpeedRatings ............ 100
    Model ...................... FinePix2650
    LightSource ................ unknown
    FileSource ................. (DSC) Digital Still Camera
    MeteringMode ............... Pattern
    ...
  $ iinfo -f DateTime dcsf002002.jpg
    2002:01:20 10:38:02


GOTCHAS

The Image::Info module also returns hash entries which in turn contain nested data structures. All of these are not displayed by iinfo for compactness.
