5.26 ConvertScale Method

Description:	Converts coordinates between specified scale modes. The details of scale mode are described in the ScaleMode property.
Used in controls:	None.
Used in objects:	Form
Parameters:	VT_I2 - ScaleModeInS9(4) COMP-5 VT_I2 - ScaleModeOutS9(4) COMP-5 VT_I4 - PosXS9(9) COMP-5 VT_I4 - PosYS9(9) COMP-5
Description of Parameters:	ScaleModeIn: The scale mode of the input coordinates. Valid values (with constants) are: 0 - Pixels(POW-SCALEPIXELS) 1 - 1/100mm (POW-SCALEHIMETRIC) 2 - 1/1000inch(POW-SCALEHIENGLISH) 3 - 1/20Points (POW-SCALETWIPS) ScaleModeOut: The scale mode to be used for the output coordinates. Valid values (with constants) are: 0 - Pixels(POW-SCALEPIXELS) 1 - 1/100mm (POW-SCALEHIMETRIC) 2 - 1/1000inch(POW-SCALEHIENGLISH) 3 - 1/20Points (POW-SCALETWIPS) PosX: The horizontal coordinates to be converted. The converted value is returned in this parameter. PosY: The vertical coordinates to be converted. The converted value is returned in this parameter
Return value:	None.

PROCEDURE DIVISION. * This example obtains the current * scale mode (Default is "3" = 1/20 * points), and converts 100 and 200 * in that scale mode, to their * values in scale mode "0" pixels).
