DR SCALE

version 6.0

DR SCALE (area; scope; anchorH; anchorV; amountH; amountV)

Parameter	Type		Description
area	Longint		4D Draw area
scope	Longint		-1=All
			0=Selected
			>0=Object ID
anchorH	Integer		0=None
			1=Left
			2=Middle
			3=Right
anchorV	Integer		0=None
			1=Top
			2=Middle
			3=Bottom
amountH	Number		Horizontal multiplier
amountV	Number		Vertical multiplier

The command DR SCALE scales the objects described by scope in area.

• If scope equals -1, DR SCALE scales all objects in the document.

• If scope equals 0, DR SCALE scales the selected objects.

• If scope is greater than 0, it must be equal to a specific object's ID; DR SCALE scales that object. If the object does not exist, DR Error returns error number 2.

anchorH and anchorV indicate which side of an object is anchored when it is scaled.

• If anchorH equals 0, the width of the object does not change and DR SCALE ignores any value for amountH.

• If anchorH equals 1, DR SCALE anchors the left side of the object.

• If anchorH equals 2, the command anchors the center of the object.

• If anchorH equals 3, the command anchors the right side of the object.

• As with anchorH, if anchorV equals 0, the height of the object does not change and DR SCALE ignores any value for amountV.

• If anchorV equals 1, DR SCALE anchors the top of the object.

• If anchorV equals 2, the command anchors the center of the object.

• If anchorV equals 3, the command anchors the bottom of the object.

DR SCALE scales objects described by scope according to the amountH and amountV parameters.

• If amountH and amountV are greater than 1, DR SCALE increases object size.

• If amountH and amountV are less than 1, DR SCALE decreases object size.

The new width of the object is equal to its current width, multiplied by amountH. The new height is similarly derived, using amountV.

The following examples are object methods for two different buttons named bDouble and bHalf. The first button doubles the size of the selected object, and the second cuts the object's size in half.

   DR SCALE (Area;0;2;2;0.5;0.5)   `bHalf

DR Get ID, DR MOVE, DR SIZE.
