rectangle function coordinates

[Guest]

Hello

     I am having trouble at something seemingly very simple.  I am trying to draw a rectangle using paths.  My issue is the coordiantes I use seem to be multiplied by 4.  I am trying to place the left top corner at 50,50 and I get it at 209,209 etc.  Hopefully someone can see the error in my ways as I have been looking at it way too long and thus cannot see the obvious.

<code>

function MyFuncAddRectangleShape(doc,x,y,width,height){
//define the path
$.writeln("x= ",x)
$.writeln("y= ",y)
$.writeln("width= ",width)
$.writeln("height= ",height)

var lineArray = new Array();
lineArray[0] = new PathPointInfo;
lineArray[0].kind = PointKind.CORNERPOINT;
lineArray[0].anchor = [x,y];//top left
lineArray[0].leftDirection = lineArray[0].anchor;
lineArray[0].rightDirection = lineArray[0].anchor;

lineArray[1] = new PathPointInfo;
lineArray[1].kind = PointKind.CORNERPOINT;
lineArray[1].anchor = [x+width, y];//top right
lineArray[1].leftDirection = lineArray[1].anchor;
lineArray[1].rightDirection = lineArray[1].anchor;

lineArray[2] = new PathPointInfo;
lineArray[2].kind = PointKind.CORNERPOINT;
lineArray[2].anchor = [x+width,y+height];//bottom right
lineArray[2].leftDirection = lineArray[2].anchor;
lineArray[2].rightDirection = lineArray[2].anchor;

lineArray[3] = new PathPointInfo;
lineArray[3].kind = PointKind.CORNERPOINT;
lineArray[3].anchor = [x,y+height];//bottom left
lineArray[3].leftDirection = lineArray[3].anchor;
lineArray[3].rightDirection = lineArray[3].anchor;

$.writeln(lineArray[0].anchor)
$.writeln(lineArray[1].anchor)
$.writeln(lineArray[2].anchor)
$.writeln(lineArray[3].anchor)

var lineSubPathArray = new Array();
lineSubPathArray[0] = new SubPathInfo();
lineSubPathArray[0].operation = ShapeOperation.SHAPEXOR;
lineSubPathArray[0].closed = true;
lineSubPathArray[0].entireSubPath = lineArray;

// now make the path
var myPathItem = doc.pathItems.add("myPath", lineSubPathArray);

myPathItem.strokePath(ToolType.PENCIL);

}

// set operations
app.preferences.rulerUnits = Units.PIXELS;
app.preferences.typeUnits = TypeUnits.PIXELS;
app.preferences.pointSize = PointType.POSTSCRIPT

// turn off dialog boxes
app.displayDialogs = DialogModes.NO;

// first close all the open documents
while (app.documents.length) {
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}

canvas = documents.add(5000,5000,300,"Canvas",NewDocumentMode.RGB,DocumentFill.WHITE,1,BitsPerChannelType.EIGHT);

MyFuncAddRectangleShape(canvas,
        50,
        50,
        50,
        50);

PathItem values are Numbers where n = pixels @ 72ppi. If your doc is not 72ppi you need to adjust the values used

MyFuncAddRectangleShape(canvas,
        50/(app.activeDocument.resolution/72),
        50/(app.activeDocument.resolution/72),
        50/(app.activeDocument.resolution/72),
        50/(app.activeDocument.resolution/72));

If you want the path to align with the pixels you will need to conver the values to integers.

An alternate approach is to set the dpi of your image to 72. Because of previous (and possibly existing) bugs in the PS API, working with the doc at 72dpi tends to avoid problems.

  var docRes = doc.resolution;
  doc.resizeImage( undefined, undefined, 72, ResampleMethod.NONE );
  try {
    // do stuff here....
  } finally {
     doc.resizeImage( undefined, undefined, docRes, ResampleMethod.NONE );
  }

Thanks guys -- thought I was missing something simple

Thank you post a nice post.

PATH TOO LONG solution provides a powerful and highly versatile solution to delete/unlock, copy/rename files and folders with long paths.
