VI10AddMoveArea
V = Vector
I = Image
Function that is used to manage the Vector Image feature (object that resides on some Qpaint versions).
The VI10AddMoveArea function adds the MOVEAREA command instructions to process queued buffering for drawing.
The MOVEAREA command moves the image to a number of pixels equal to x on the horizontal axis and y on the vertical axis.
If x is positive the move will be to the right, if x is negative, the move will be to the left.
If y is positive the move will be to the upward, is y is negative, the move will be to the down.

IMPLEMENTATION
VI10AddMoveArea (awBuffer, Spazio_X, Spazio _Y)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| IN | ARRSYS / ARRGBL | awBuffer | W | Array that serves as a buffer for instructions/data |
| IN | CONST/ GLOBAL | Spazio_X | W | Variable containing the space by shifting the image along the X axis. X positive = move to the right X negative = move to the left |
| IN | CONST/ GLOBAL | Spazio_Y | W | Variable containing the space by shifting the image along the Y axis. Y positive = move to the upward Y negative = move to the down |
