A logo file must contain a key. If no key is found the entire image will be displayed
i.e. a rectangle cut-out of the logo image size
•
Maximum logo size of 400 Pixels by picture height (Max. 480 lines)
Logo naming convention
:
•
All logo files take the form
<logo_name><specifier>.<extension>
where
<logo_name>
equals the directory's name.
•
Logo filenames must be all in lowercase.
•
A
<specifier>
of the form
_<standard>
indicates that this logo is intended for this
specific standard. If no
_<standard>
specifier is included, then this logo is the
default for any standards which do not have a standard-specific logo.
Possible values for
<standard>
are: 525i, 625i, 720p, 1080p and 1080i.
•
A
<specifier>
of the form
_<index>
indicates that this file is part of a multi-file
sequence for an animated logo. Any non-negative decimal value may be used for
<index>
. The files in a sequence are sorted in increasing order of their respective
<index>
es by numerical value. Leading zeros do not affect the sort order, and it is
not required that the
<index
> values are contiguous, however all images in a
multi-file sequence must have the same width and height.
•
If both
_<standard>
and
_<index>
specifiers are used, then they should be written
as
_<standard>_<index>
, not
_<index>_<standard>
.
•
The
<extension>
is ignored, the KudosPro unit will auto-detect the actual image
format.

•
sam_1080p.png
