Hi,
Need to do some simple line drawing in a Javascript plugin and first did this based on docs
|
createPoint: function(x, y) { |
| |
var unit_x = new UnitValue(x, "px") |
| |
var unit_y = new UnitValue(y, "px") |
| |
var coords = [unit_x.as("pt"), unit_y.as("pt")] |
| |
var point = new PathPointInfo(); |
| |
point.anchor = coords |
| |
point.leftDirection = coords |
| |
point.rightDirection = coords |
| |
point.kind = PointKind.CORNERPOINT |
},
drawLine: function(x1, y1, x2, y2) {
| |
var startPoint = Photoshop.createPoint(x1, y1) |
| |
var stopPoint = Photoshop.createPoint(x2, y2) |
| |
var spi = new SubPathInfo() |
| |
spi.closed = false |
| |
spi.operation = ShapeOperation.SHAPEXOR |
| |
spi.entireSubPath = [startPoint, stopPoint] |
| |
var line = app.activeDocument.pathItems.add("Line", [spi]) |
| |
line.strokePath(ToolType.PENCIL) |
| |
line.remove() |
},
|
Now this misaligns the lines, i.e. coordinates are not where they should. The px->pt conversion should be OK at least from settings. I.e. I have PS set to 72dpi and result is pt=px. If I manually scale by 72/96, it almost aligns but not quite. So sounds like there is some transform/scale in place that might be doc specific that should be applied. Any thoughts?
More searching found me this that is working, but I'd prefer to use just SDK where I can..

drawLine: function (x1, y1, x2, y2, width) { |
| |
var desc = new ActionDescriptor() |
| |
var lineDesc = new ActionDescriptor() |
| |
|
| |
var startDesc = new ActionDescriptor() |
| |
startDesc.putUnitDouble( charIDToTypeID('Hrzn'), charIDToTypeID('#Pxl'), x1 ) |
| |
startDesc.putUnitDouble( charIDToTypeID('Vrtc'), charIDToTypeID('#Pxl'), y1 ) |
| |
lineDesc.putObject( charIDToTypeID('Strt'), charIDToTypeID('Pnt '), startDesc ) |
| |
var endDesc = new ActionDescriptor() |
| |
endDesc.putUnitDouble( charIDToTypeID('Hrzn'), charIDToTypeID('#Pxl'), x2 ) |
| |
endDesc.putUnitDouble( charIDToTypeID('Vrtc'), charIDToTypeID('#Pxl'), y2 ) |
| |
lineDesc.putObject( charIDToTypeID('End '), charIDToTypeID('Pnt '), endDesc ) |
| |
lineDesc.putUnitDouble( charIDToTypeID('Wdth'), charIDToTypeID('#Pxl'), width || 1 ) |
| |
desc.putObject( charIDToTypeID('Shp '), charIDToTypeID('Ln '), lineDesc ) |
| |
desc.putBoolean( charIDToTypeID('AntA'), true ) |
| |
executeAction( charIDToTypeID('Draw'), desc, DialogModes.NO ) |
}
