Resize Artboard based on Center Bottom

[Wilson Faustino]

Hello!

I'd like to start a script to resize my artboard (in my case, just one for document) based on Center-Bottom reference point.

Example: my file originally have 200x100mm and I want to change to 230x140mm without moving any content.

reason: I work with a lot of label that change the page size only depending of which manufacturer. (I will build a database inside the script after).

Any clue will be appreciated.

Hi,

You can reference below article.

However, previouse one based Top-Left position and you have to calculate and set to Bottom-Center.

Hi

Thanks a lot for the article indication which was very helpful, but I found another article Re: Is it possible to resize all artboards at once the way you used to be able to do in document set... by CarlosCanto​ that brought me this:

#target Illustrator  
//  script.name = resizeArtboards_CS4andUp.jsx;  
//  script.description = resizes all artboards;  
//  script.requirement = one document with at least one artboard;  
//  script.parent = carlos canto // 11/4/12;  
//  script.elegant = false;  
if (app.documents.length > 0) {  
        //alert("more than 0");  
                    var idoc = app.activeDocument;  
        var title = "Resize All Artboards";  
        var width = Number(Window.prompt ("Enter New Artboard Width in points", 400, title));  
        var height = Number(Window.prompt ("Enter New Artboard Height in points", 250, title));  
    for (i=0; i<idoc.artboards.length; i++) {  
        var abBounds = idoc.artboards.artboardRect;// left, top, right, bottom  
        var ableft = abBounds[0]; // 0  
        var abtop = abBounds[1]; // 612  
        var abwidth = abBounds[2] - ableft; // 792 // width  
        var abheight = abtop- abBounds[3]; // 0 // height  
        var abctrx = abwidth/2+ableft;  
        var abctry = abtop-abheight;//edited from original  
        var ableft = abctrx-width/2;   
        var abtop = abctry+height;//edited from original  
        var abright = abctrx+width/2;   
        var abbottom = abBounds[3]; //edited from original 
        idoc.artboards.artboardRect = [ableft, abtop, abright, abbottom];  
    }  
}  
 else  {  
        alert ("there are no open documents");  
}  

I hope it helps somebody else with the same question.

So what if I went to set the artboard to inches instead of point and what If I want it to center from the middle?

Thanks
