Image files
The image files are described as ASCII text in XML format i.e. a header and the different elements and their value placed between
tags :
<?xml version="1.0" encoding="UTF-8" ?>
<ImageFile>
<FileSelection>
<InputLayer />
<SourceType />
<LineDuration Discrepancy="427" Unit="ns">20677</LineDuration>
<TotalLines Discrepancy="0">806</TotalLines>
<Interlaced>no</Interlaced>
</FileSelection>
<ImageDefinition>
<TotalPixels>1344</TotalPixels>
<ActivePixels>1024</ActivePixels>
<PixelStart>135</PixelStart>
<ActiveLines>768</ActiveLines>
<LineStart>29</LineStart>
<AspectRatio>4:3</AspectRatio>
</ImageDefinition>
</ImageFile>
Since the XML file is parsed internally in the projector it will return a NACK if the data is not valid (does not respect the XML com-
pleteness rules).
Desktop error strings
The operating system (Windows
TM
) uses a yellow notification arrea to display errors and messages. These messages appear in the
lower right corner of the desktop.
The acknowledge bytes are followed by a character string representing the actual message or error displayed.
An example is the error
“No image file found”
that can be generated when selecting a inactive (not present) source.
The character string sent is the following :
\x2b\x00\xff\xff\xff\xf1\x00\x4e\x00\x6f\x00\x20\x00\x49\x00\x6d\x00\x61\x00\x67\x00\x65\x00\x66\x00\x69\x00
Note that each character is followed by the \x00, the string being also ended with \x00.
