The initial value of mValueTX and mValueTY

[OMOTI]

Hello.

Does the initial values of mValueTX and mValueTY of the object just generated refer the upper left coordinates of the document's largest area? For example, TextFrameItem and PlacedItem.

I want to get the coordinates of the document's largest area easily. Do you have any sugesstions?

I referred to here.

How to get bounds of largest possible document area?

This script worked fine on Illustrator CS6, CC2015, CC2017, CC2018 (for mac).

Is this correct?

function getLargestBounds() {
    var tempLayer,
        tempText,
        left,
        top,
        LARGEST_SIZE = 16383;
    if (!app.documents.length) {
        return;
    }
    tempLayer = app.activeDocument.layers.add();
    tempText = tempLayer.textFrames.add();
    left = tempText.matrix.mValueTX;
    top = tempText.matrix.mValueTY;
    tempLayer.remove();
    return new Rect(
        left,
        top,
        left + LARGEST_SIZE,
        top + LARGEST_SIZE
    );
}
var rect = getLargestBounds();
// cover the whole area.
app.activeDocument.pathItems.rectangle(rect[1], rect[0], 16383, 16383);

Hi OMOTI, that seems to be correct. It works, thanks for sharing!!

Hi CarlosCanto, thank you for testing.

Which is your OS, Windows or macOS?

I wish I could know the Windows information.

Windows 10, CC2018.

I used to use the previous methods mentioned in the link, luckily I've only needed to find the absolute 0,0 on new documents when conditions are know. This method is more reliable.

thanks

thanks for your help.

I'm sorry. The coordinates of the return value were incorrect.

Correctly here.

return new Rect(
     left,
     top,
     left + LARGEST_SIZE,
     top - LARGEST_SIZE
);
