Screen Dump Query
:HCOPy:SDUMp:DATA? [GIF]|BMP|WMF
The query returns the current screen image as a file. If the optional file
type is not specified it returns GIF type graphic data. The orientation is
always portrait and the image is always in color.
The data is formatted as block data where the block of data starts with
an ASCII header that indicates how many additional binary data bytes
are following in the block. (e.g. #DNNN<binary data>) The binary data
is the actual graphics file. To process the block of data you would:
• Read the first header byte #. The # tells you to read the next digit
(D). That digit tells you how many additional digits there are in the
header. (In the above example D=3.)
• Then read the next D bytes. The digits NNN tell you the number of
bytes of data there are following the header. (The data format, like
binary16, affects how many values are represented by the bytes.)
• Those data bytes can then be saved as a separate file with a .gif .bmp
or .wmf suffix to use in other applications.
