img-tiff - Tagged Image File Format (tiff)








package require img::tiff ?2.0?












package require img::tiff


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 Tagged Image File Format
    (tiff). More specifically img::tiff extends Tk's photo
    [https://www.tcl.tk/man/tcl9.0/TkCmd/photo.html] image type.


The name of the new format handler is tiff. 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 tiff format (options -data and -file) is
      detected automatically.

  
[2]

  
The format name tiff 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::tiff is a sub-package of Img. It
    can be loaded as a part of the complete Img support, via package require
    Img, or on its own, via package require img::tiff.
