VidGet X Y DX DY Collects video attributes from a rectangle on the
emulation screen (video attributes relate only to the
actual appearance of the field on the screen, as
opposed to field-oriented attributes). If the length DX
is not specified then attributes for the rest of the line
will be returned. If the number of rows DY is not
specified then attributes for one line will be deliv-
ered. If the position is not specified then the current
cursor position will be used.
Attributes are returned in binary format with 16 bits
per character position. The significance of the attri-
bute bits is as follows:
0x8000 Inverse
0x4000 Wide line
0x2000 Reserved
0x1000 Sixel graphic
0x0800 Double height (lower)
0x0400 Blink
0x0200 Double width
0x0100 Double height
0x0080 Underline
0x0040 Red background
0x0020 Green background
0x0010 Blue background
0x0008 Bold
0x0004 Red foreground
0x0002 Green foreground
0x0001 Blue foreground
If you wish to read data from the status line, you can
do this by specifying a row number of zero (in which
case only one line will be delivered).
VidTxt X1 Y1 X2 Y2 Collects video attributes from the emulation screen
in a line-oriented fashion (video attributes relate only
to the actual appearance of the field on the screen, as
opposed to field-oriented attributes). The position of
the first attribute to transfer and the last attribute to
transfer should be specified with the command (all
four parameters must be specified).
