Script to Resize Artboard Dimensions if They're Below Specified Width or Height

Hello world! I've built a script for Illustrator 2019 that checks if any artboards are under a certain minimum size specified as var width & var height and resizes any that are under those widths or heights to another specified height/width. It's commemted out so much that even a complete noob like me would understand every little thing it does.

It's based on this script here: https://github.com/iconifyit/ai-scripts/blob/master/Resize%20All%20Artboards.jsx

which i think is based on Carlos Cantos' script from these forums.

Here's a script for if you only need the width checked:

#target Illustrator  

    var idoc  = app.activeDocument;

    var width = (7*72) //# of inches multiplied by ppi which is 72
    //var height = (7*72) //uncomment this if you want to set height as well

    for (i=0; i<idoc.artboards.length; i++) {

            var abBounds = idoc.artboards[i].artboardRect; // the contents of this list are 0=left, 1=top, 2=right, 3=bottom


            var ableft = abBounds[0]; //these 4 vars just set the bounds of the artboard to readable names
            var abtop = abBounds[1];
            var abright = abBounds[2];
            var abbottom = abBounds[3];

            var abwidth = abBounds[2] - ableft; // these 2 vars calculate the width & height based on the bounds. right - left = width
            var abheight = abtop- abBounds[3]; // top - bottom = height

            var abctrx = abwidth/2+ableft; //these 2 vars help center the artboard
            //var abctry = abtop-abheight/2; //uncomment this if you want to set height as well

            var ableft = abctrx-width/2; //these 4 vars calculate the new bounds of the artboard
            //var abtop = abctry+height/2;  //uncomment this if you want to set height as well
            var abright = abctrx+width/2;
            //var abbottom = abctry-height/2;  //uncomment this if you want to set height as well


           /** if (abwidth < (6*72) && abheight < (6*72)) { //this if statement detects if your width & height is under your set # of inches multiplied by ppi which is 72 (since illustrator measures in pixels). if it's lower, it resizes it to var width & var height shown above.

                idoc.artboards[i].artboardRect = [ableft, abtop, abright, abbottom]; } else { //this resizes the width & height, artboard centered
            */      
                    
                    //uncomment above for fixing height as well
                if (abwidth < (6*72)) { 

                    idoc.artboards[i].artboardRect = [ableft, abBounds[1], abright, abBounds[3]]; } //this resizes the width only if it's less than specified above, artboard centered
                /** else { if (abheight < (6*72)) {
                        idoc.artboards[i].artboardRect = [abBounds[0], abtop, abBounds[2], abbottom]; //this resizes the height only if it's less than specified above, artboard centered
                    }}} */
                    //uncomment above for fixing height as well
                }

& Here's a version if you want it to check both width & height and fix only the dimension(s) that are smaller than the set thresholds.

#target Illustrator  

    var idoc  = app.activeDocument;

    var width = (7*72) //# of inches multiplied by ppi which is 72
    var height = (7*72) //uncomment this if you want to set height as well

    for (i=0; i<idoc.artboards.length; i++) {

            var abBounds = idoc.artboards[i].artboardRect; // the contents of this list are 0=left, 1=top, 2=right, 3=bottom


            var ableft = abBounds[0]; //these 4 vars just set the bounds of the artboard to readable names
            var abtop = abBounds[1];
            var abright = abBounds[2];
            var abbottom = abBounds[3];

            var abwidth = abBounds[2] - ableft; // these 2 vars calculate the width & height based on the bounds. right - left = width
            var abheight = abtop- abBounds[3]; // top - bottom = height

            var abctrx = abwidth/2+ableft; //these 2 vars help center the artboard
            var abctry = abtop-abheight/2; //uncomment this if you want to set height as well

            var ableft = abctrx-width/2; //these 4 vars calculate the new bounds of the artboard
            var abtop = abctry+height/2;  //uncomment this if you want to set height as well
            var abright = abctrx+width/2;
            var abbottom = abctry-height/2;  //uncomment this if you want to set height as well


           if (abwidth < (6*72) && abheight < (6*72)) { //this if statement detects if your width & height is under your set # of inches multiplied by ppi which is 72 (since illustrator measures in pixels). if it's lower, it resizes it to var width & var height shown above.

                idoc.artboards[i].artboardRect = [ableft, abtop, abright, abbottom]; } else { //this resizes the width & height, artboard centered
                 
                    
                    //uncomment above for fixing height as well
                if (abwidth < (6*72)) { 

                    idoc.artboards[i].artboardRect = [ableft, abBounds[1], abright, abBounds[3]]; } //this resizes the width only if it's less than specified above, artboard centered
                else { if (abheight < (6*72)) {
                        idoc.artboards[i].artboardRect = [abBounds[0], abtop, abBounds[2], abbottom]; //this resizes the height only if it's less than specified above, artboard centered
                    }}}
                    //uncomment above for fixing height as well
                }

Thanks for checking this out!
