cmd_stopic |
Function (ROM Call 0x391) |
Executes TI-Basic 'StoPic' command.
cmd_stopic displays the Graph Screen and stores a part of it in a TI-Basic
PIC variable.
This function expects one of the following layouts on the expression stack:
Additionally, each of the entries x, y and width may be
omitted and replaced with NOTHING_TAG.
The parameter Args should point to the tag of the last item (i.e.
symname). x, y, width and height should
be integer items. x and y represent the upper left corner
of the area to copy. Both default to 0 if they are omitted. width and
height specify the dimensions in pixels. They default to the width and
height of the whole graph screen. The symname entry is the VAT symbol
name of a TI-Basic variable in which the graph data will be stored (it will
be created if it does not exist).
See BitmapGet for a much faster
low-level way of getting bitmapped data, independently of the Graph Screen.
Uses: GetValue, next_expression_index, gr_active, gr_stopic, GraphActivate
