:PIXel? TRACe<n>
Parameter
<n>
<NR1> trace 1~4
Return Parameter
<pixel data>
Pixel data. Returned as ASCII code in
binary coded decimal format:
pixel1#HbyteLbyte
pixel2#HbyteLbyte
pixel3#HbyteLbyte........and so on until
the EOF character
Example

For example, data for the first pixel is returned as
“?H”, the second as “\x”, the third as “16” and so on.
Using the first pixel data as an example, the high byte
is “?” and the low byte as “H”. To convert this data
into a pixel value, follow the steps below:
? H
? H

High byte, low byte
converted into binary
Combine high byte &
low byte
Convert binary into
decimal
Divide the pixel data by
100 to get the pixel value
