PVIEW
Type: Command
Description: PICT View Command: Displays PICT with the specified coordinate at the upper left corner of
the graphics display.
PICT must fill the entire display on execution of PVIEW. Thus, if a position other than the
upper left corner of PICT is specified, PICT must be large enough to fill a rectangle that extends
131 pixels to the right and 80 pixes down on the hp49g+ (64 pixels down on the hp48gII).
If PVIEW is executed from a program with a coordinate argument (versus an empty list), the
graphics display persists only until the keyboard is ready for input (for example, until the end of
program execution). However, the FREEZE command freezes the display until a key is pressed.
If PVIEW is executed with an empty list argument, PICT is centred in the graphics display with
scrolling mode activated. In this case, the graphics display persists until −is pressed.
PVIEW does not activate the graphics cursor or the Picture menu. To activate the graphics
cursor and Picture menu, execute PICTURE.

PX→C
Type: Command
Description: Pixel to Complex Command: Converts the specified pixel coordinates to user-unit coordinates.
The user-unit coordinates are derived from the (x
min
, y
min
) and (x
max
, y
max
) parameters in the
reserved variable PPAR. The coordinates correspond to the geometrical center of the pixel.
Access: !°L
