Hi, 

I'd like to do this : on photoshop file, draw a line, then, with a script, automatically draw to the extremities a vertical line of 54px length (width 7 px.)

Is it possible to made a script for this ?

Thanks in advance, 

Christian

Try this script:

#target photoshop

var oldPrefs = app.preferences.rulerUnits
app.preferences.rulerUnits = Units.POINTS
var doc = activeDocument;
var curLay = doc.activeLayer;
var curLayName = curLay.name
var res = doc.resolution;
var len54 = 54*(72/res);

var path1 = doc.pathItems.getByName(curLay.name + ' Shape Path');
var p1 = path1.subPathItems[0]
var pt1 = p1.pathPoints[0].anchor
var pt2 = p1.pathPoints[1].anchor

var totalPath = new Array();
var newPath = new Array();

newPath[0] = new PathPointInfo
newPath[0].kind = PointKind.CORNERPOINT;    

newPath[0].anchor = Array(pt1[0],pt1[1]+len54);
newPath[0].rightDirection = Array(pt1[0],pt1[1]+len54);
newPath[0].leftDirection = Array(pt1[0],pt1[1]+len54);

To have it use the center stroke, add this code to the very end of the script, before the last brace "}" in the function setStoke().

 

var idsetd = charIDToTypeID( "setd" );
    var desc36 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref14 = new ActionReference();
        var idcontentLayer = stringIDToTypeID( "contentLayer" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref14.putEnumerated( idcontentLayer, idOrdn, idTrgt );
    desc36.putReference( idnull, ref14 );
    var idT = charIDToTypeID( "T   " );
        var desc37 = new ActionDescriptor();
        var idstrokeStyle = stringIDToTypeID( "strokeStyle" );
            var desc38 = new ActionDescriptor();
            var idstrokeStyleLineAlignment = stringIDToTypeID( "strokeStyleLineAlignment" );
            var idstrokeStyleLineAlignment = stringIDToTypeID( "strokeStyleLineAlignment" );
            var idstrokeStyleAlignCenter = stringIDToTypeID( "strokeStyleAlignCenter" );
            desc38.putEnumerated( idstrokeStyleLineAlignment, idstrokeStyleLineAlignment, idstrokeStyleAlignCenter );
            var idstrokeStyleVersion = stringIDToTypeID( "strokeStyleVersion" );
            desc38.putInteger( idstrokeStyleVersion, 2 );
            var idstrokeEnabled = stringIDToTypeID( "strokeEnabled" );
            desc38.putBoolean( idstrokeEnabled, true );
        var idstrokeStyle = stringIDToTypeID( "strokeStyle" );
        desc37.putObject( idstrokeStyle, idstrokeStyle, desc38 );
    var idshapeStyle = stringIDToTypeID( "shapeStyle" );
    desc36.putObject( idT, idshapeStyle, desc37 );

    If I could ask latest latest one more thing : what I could change in the script to have other angles : 

    - horizontal left, or right

    - vertical up or down, 

    like on screenshot in red, green and violet

    (always the same lenght 54 px)

    I read your script and documentation, but I didn't find (didn't understand) how to write/modify to do this.

    Thanks a lot, again.... :-))

    Use the pen tool to draw a line: just set two points.

    Your script works but changes the stroke color to black and the stroke weight  to 7px.

    That's what the OP wanted, a 7px stroke. The screen shot that was posted shows a black stroke, so that's what I went with. The script actually deletes the original layer, as you can't just edit a path or shape, you have to redraw it.

    If  you create a line shape layer that has a that has stroked line paths. With that layer  active a script  could most like get  line paths info  and add  vertical 54px vertically down lines to the line end control points.

    If you are new to scripting you need the read the Adobe three scripting doc PDF  download and install the scriptlistener Plugin and look ate the sample scripts source code and the script the Adobe has provided in Photoshop Presets\Scripts folder.  You have a lot to learn. It will take some time. I just hack at Scripting.
