Hi,

I want the equivalent of choosing Object > Transform > Reflect, across the Vertical axis. How would I do this with JavaScript?

Thanks,

Max

Try below code:

function applyTM(tg, a, b, c, d) {

  var tm = new Matrix();

  tm.mValueA = a;

  tm.mValueB = b;

  tm.mValueC = c;

  tm.mValueD = d;

  tm.mValueTX = 0;

  tm.mValueTY = 0;

  tg.transform(tm,true,true,true,true,1);

  app.redraw();

  }

applyTM (app.activeDocument.selection[0],-1,0,0,1);

if you want to transform horizontal:

applyTM (app.activeDocument.selection[0],1,0,0,-1);

var totalMatrix = app.getScaleMatrix(-100, 100); // Cria a matriz de escala

var layer = app.activeDocument.activeLayer; // Obtém a camada ativa

for (var i = 0; i < layer.pageItems.length; i++) {
// Itera por todos os itens na camada
var currentItem = layer.pageItems[i];

// Verifica se o nome do item é "verso" antes de aplicar a matriz de escala
if (currentItem.name === "verso") {
currentItem.transform(totalMatrix);
}
}

This code works!

var totalMatrix = app.getScaleMatrix(-100, 100); // Create the scale matrix

 

var layer = app.activeDocument.activeLayer; // Get the active layer

 

for (var i = 0; i < layer.pageItems.length; i++) {
        // Iterate through all items in the layer
        var currentItem = layer.pageItems[i];

 

        // Check if the item's name is "verso" before applying the scale matrix
        if (currentItem.name === "verso") {
                currentItem.transform(totalMatrix);
        }
}

But u got change the name of the object to "verso" and the layers to "Camada 1"

    Hi,

    There's a script created by our friend Gustavo Del Vechio (Reflex 1.0), he made a tool for that, follow your site:

    Scripts (English) | Núcleo do Illustrator

    Thanks again Gustavo!

    No reason for this comment other than to point that, it contains legends of our industry (not talking about myself of course)

    Max this is AppleScript but should at least give you a clue to using the transform object and matrix values. You should be able to translate to JavaScript.

    tell application "Adobe Illustrator"
    activate
    set Doc_Ref to the current document
    tell Doc_Ref
    set Group_XY to position of group item 1 of layer 1
    set RefVert_Matrix to ¬
    {class:matrix, mvalue_a:-1.0, mvalue_b:0.0, mvalue_c:0.0, mvalue_d:1.0, mvalue_tx:0.0, mvalue_ty:0.0}
    transform group item 1 of layer 1 using RefVert_Matrix about center
    set position of group item 1 of layer 1 to Group_XY
    end tell
    end tell

    BTW when ever I have used this it always appears to move very slightly so check your bounds before and after.

    Try below code:

    function applyTM(tg, a, b, c, d) {

      var tm = new Matrix();

      tm.mValueA = a;

      tm.mValueB = b;

      tm.mValueC = c;

      tm.mValueD = d;

      tm.mValueTX = 0;

      tm.mValueTY = 0;

      tg.transform(tm,true,true,true,true,1);

      app.redraw();

      }

    applyTM (app.activeDocument.selection[0],-1,0,0,1);

    if you want to transform horizontal:

    applyTM (app.activeDocument.selection[0],1,0,0,-1);
