GMImage.AddPathCurvetoAbs

Draw a single curve.

Component Version macOS Windows Linux Server FileMaker iOS SDK
GraphicsMagick 4.1 Yes Yes Yes Yes Yes
MBS( "GMImage.AddPathCurvetoAbs"; ImageRef; x1; y1; x2; y2; x; y )   More

Parameters

Parameter Description Example
ImageRef The image reference number. 1
x1 The first control point.
y1 The first control point.
x2 The second control point.
y2 The second control point.
x Destination point coordinate.
y Destination point coordinate.

Result

Returns OK or error.

Description

Draw a single curve.
Draws a cubic Bézier curve from the current point to (x,*y*) using (x1,*y1*) as the control point at the beginning of the curve and (x2,*y2*) as the control point at the end of the curve. GMImage.AddPathCurvetoAbs indicates that absolutecoordinates will follow; GMImage.AddPathCurvetoRel indicates that relative coordinates will follow. Multiple sets of coordinates may be specified to draw a polybezier. At the end of the command, the new current point becomes the final (x,*y*) coordinate pair used in the polybezier.

Examples

Draws a bezier curve:

$r = MBS("GMImage.AddPathMovetoAbs"; $img; 100; 100 )
$r = MBS("GMImage.AddPathCurvetoAbs"; $img; 100; 300; 300; 100; 300; 300 )
$r = MBS("GMImage.DrawPath"; $img )
