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








package require img::flir ?2.0?












package require img::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 image create
    photo ?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
    package require Img, but must be loaded explicitly via package
    require img::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:



  

  
Available since version 1.4.9.
    
If set to true, additional information about the read
        data is printed to stdout. Default is false.

  

  

  
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.







  

  
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.

  

  

  
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.

  

  

  
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.

  

  

  
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.

  

  

  
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.
