packagerequireimg::flir

       Like  all packages of Img it does not provide new commands, but extends the existing Tk command image, so
       that it supports files containing raster images  in  the  FLIR  FPF  Public  Image  format  (flir).  More
       specifically img::flir extends Tk's photo [https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html] image type.

       The  name of the new format handler is flir.  This handler provides new additional configuration options.
       See section Options for more detailed explanations.

       All of the above means that in a call like imagecreatephoto ?name? ?options?

       [1]    Image data in flir format (options -data and -file) is detected automatically.

       [2]    The format name flir is recognized by the option -format.

       In addition the value of option -format is treated as a list and may contain any of the  special  options
       listed in section Options.

       The  package  img::flir is not loaded when doing a packagerequireImg, but must be loaded explicitly via
       packagerequireimg::flir.

       img-flir - FLIR FPF Public Image format (flir)

       [1]    This format handler interprets FLIR temperature files as grayscale images.

       [2]    Temperature values specified as short, int, float and double are supported.

       [3]    This format handler only supports read functionality.

       The handler provides the following options:

       -verbosebool
              Available since version 1.4.9.

              If set to true, additional information about the read data is printed to stdout. Default is false.

       -mapstring
              Available since version 1.4.9.

              Specify the mode when mapping the 16, 32 or 64-bit temperature values to  8-bit  grayscale  values
              for displaying.  Possible values: none, minmax, agc.  Default mode is minmax.

              [1]    If  mode  is  set  to none, no mapping of input values is done. Use this mode, if the input
                     values are already in the range of 0 ..255.  When using mode none, no information about the
                     minimum and maximum input values is gathered during reading and therefore no verbose output
                     is printed.  On the other hand reading the input data is faster.

              [2]    Mode minmax maps the minimum and maximum input data to 256 grayscale values.

              [3]    Mode agc applies an automatic gain control  algorithmn  to  the  input  values.   Currently
                     implemented for 1-channel 32-bit float images only.

       -mindouble
              Available since version 1.4.9.

              Specify  the  minimum pixel value to be used for mapping the input data to 8-bit image values.  If
              not specified or negative, the minimum value found in the image data.   Valid  for  mapping  mode:
              minmax.

       -maxdouble
              Available since version 1.4.9.

              Specify  the  maximum pixel value to be used for mapping the input data to 8-bit image values.  If
              not specified or negative, the maximum value found in the image data.   Valid  for  mapping  mode:
              minmax.

       -gammadouble
              Available since version 1.4.9.

              Specify  a  gamma  correction  to  be  applied  when mapping the input data to 8-bit image values.
              Default is 1.0.  Valid for mapping modes: minmax and agc.

       -saturationdouble
              Available since version 1.4.9.

              The supplied value specifies the  saturation  value,  i.e.  all  input  values  greater  than  the
              saturation value are mapped to white.  If not specified or negative, do not use saturation.  Valid
              for mapping mode: agc.

       -cutoffdouble
              Available since version 1.4.9.

              The  supplied value specifies the cut-off value in percent.  The cut-off value specifies, how many
              pixels from the lower and upper part of the histogram are not considered for mapping.  This option
              is useful, if there are some hot or cold spots in the image.  Default is 3.0.  Valid  for  mapping
              mode: agc.
