RIGOL
Return Format
The query returns the bitmap data stream in strings.
The returned value consists of the TMC data block header and BMP data. The format and detailed Remarks
of each part are as shown in the table below.
TMC Data Block Header
Size
[1]
N +2
(Length)
Format
#NX...X
It is used to describe the length of the data stream (the
number of bytes).
Wherein, # is the start identifier of the data stream; N≤9
denotes that N-digit data following the start identifier are
Remarks
used to describe the length of the data stream (the
number of bytes).
For example, #9001152054.
Wherein, N is 9, and 001152054 represents that the data
stream contains 1152054 bytes of effective data.
[1] : N is the width of the bits that are used to describe the data length in the TMC data block header.
Note
For example, 9 in #9001152054.
[2] is 800, the height is 480, the bit depth is 24 bit (3 bytes), and 54 is the size of the bitmap
