MBS( "DynaPDF.ScaleCoords"; PDF; x; y )

Parameters

PDF The PDF reference returned from DynaPDF.New. $pdf
x Scale factor of the x-axis $x
y Scale factor of the y-axis $y

Result

Returns OK on success and error on failure.

Description

The function scales the coordinate system by applying a transformation matrix.
It is highly recommended to save the graphics state beforehand, otherwise it is very difficult or impossible to restore the coordinate system later.
After scaling the coordinate system, bottom-up coordinates are active. It is not possible to use top- down coordinates inside a scaled coordinate system.
Please do not try to scale/skew/translate back later. use DynaPDF.SaveGraphicState and DynaPDF.RestoreGraphicState.

Examples

Scale and draw rectangle:

MBS( "DynaPDF.SaveGraphicState"; $PDF )
MBS( "DynaPDF.ScaleCoords"; $PDF; 2; 2)
MBS( "DynaPDF.Rectangle"; $PDF; 0; 0; 200; 100; "stroke" )
MBS( "DynaPDF.RestoreGraphicState"; $PDF )
