◆ changeDrawingBitmapLayerResolution

void DrawingTools::changeDrawingBitmapLayerResolution	(	QScriptValue	drawingKey,
		double	pixelPerModelUnit,
		QScriptValue	options = `QScriptValue()`
	)

slot

Changes the bitmap layer resolution of a given drawing.

The example below uses DrawingTools.changeDrawingBitmapLayerResolution(..) to change all art layers (0=underlay, 1=line art, 2=color art, 3=overlay) resolutions of the 2nd drawing associated with a given node timing column.

var columnId = node.linkedColumn("Top/Drawing_2", "DRAWING.ELEMENT");
var elementKey = column.getElementIdOfDrawing(columnId);
var timings = column.getDrawingTimings(columnId);
var dk = Drawing.Key(elementKey, timings[1]);
DrawingTools.changeDrawingBitmapLayerResolution(dk, 0.1, {resampleBitmap:true, art:[2]});

Parameters

drawingKey	: The drawing identifier
pixelPerModelUnit	: The new normalized pixel density (1.0 = 100%)
options	: Optional parameters. The following properties are supported :

Property	Type	Default Value	Description
resampleBitmap	bool	true	Will only resample existing bitmaps if set to true.
art	Array	[0,1,2,3]	Controls which art layers are targeted by the function call (0=underlay, 1=line art, 2=color art, 3=overlay)

◆ changeDrawingVectorLayerResolution

void DrawingTools::changeDrawingVectorLayerResolution	(	QScriptValue	drawingKey,
		double	pixelPerModelUnit,
		QScriptValue	options = `QScriptValue()`
	)

slot

Changes the vector layer resolution of a given drawing.

The example below uses DrawingTools.changeDrawingVectorLayerResolution(..) to change all art layers (0=underlay, 1=line art, 2=color art, 3=overlay) resolutions of the first drawing associated with a given node timing column.

var columnId = node.linkedColumn("Top/Drawing_1", "DRAWING.ELEMENT");
var elementKey = column.getElementIdOfDrawing(columnId);
var timings = column.getDrawingTimings(columnId);
var dk = Drawing.Key(elementKey, timings[0]);

     MessageLog.trace("The selected node is NOT an Element Node. " );
     return;
  }
  var attrType = node.getTextAttr(n, 1, "lineArtDrawingMode");

     return;
   }
  var destination = n + "_vect";
  if (!node.getName(destination))
   {
      MessageLog.trace("Please make sure there is a node named " + node.getName(n) + "_vect in the same group as the selected node" );

   for(var i=1 ; i<frame.numberOf() ; ++i)
   {
     var keySrc = Drawing.Key({ node: n , frame : i});
     var keyDst = Drawing.Key({ node: destination , frame : i});
     if (keySrc.isNull || keyDst.isNull)
     {
         continue;
     }
    var r = DrawingTools.vectorize(keySrc, keyDst, options);
   }
   scene.endUndoRedoAccum();
}

Will vectorize the drawing and create an undo command when the destination drawing is a key. It is not undoable when the destination is a file.
The list of options available for the vectorize method can be obtained by calling DrawingTools.vectorize.help();

Returns
false if it fails and true if is succeeds.
