FUNCTIONS

get_display_resolution_name

Usage:

 get_display_resolution_name(%args) -> str|array[str]

Get the known name for a display resolution size.

Examples:

  • You can specify width and height ...:

     get_display_resolution_name(height => 480, width => 640); # -> [200, "OK", "MCGA", {}]
  • ... or size directly (in "x x y" or "x*y" format):

     get_display_resolution_name(size => "1280x720"); # -> [200, "OK", "720p", {}]
  • Return all names:

     get_display_resolution_name(size => "1280x720", all => 1); # -> [200, "OK", ["720p", "HD", "WXGA 16:9"], {}]
  • Unknown resolution size:

     get_display_resolution_name(size => "999x666"); # -> [200, "OK", undef, {}]

Will return undef if there is no known name for the resolution size.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • all => bool

    Return all names instead of the first one.

    When set to true, an arrayref will be returned instead of string.

  • height => posint

  • size => str

  • width => posint

Return value: (str|array[str])

Get the size of a display resolution name.

Examples:

  • Example #1:

     get_display_resolution_size(name => "VGA"); # -> [200, "OK", "640x480", {}]
  • Unknown name:

     get_display_resolution_size(name => "foo"); # -> [200, "OK", undef, {}]

Will return undef if the name is unknown.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • name* => str

Return value: (str)

list_display_resolution_names

Usage:

 list_display_resolution_names() -> hash

Examples:

  • Example #1:
