Illustrator script to create symbols from images in folder
Time to give back to the community...
Here is a script I recently devised to bulk create symbols from images in a folder. Tested with Illustrator CC 2014.
// Import Folder's Files as Symbols - Illustrator CC script
// Description: Creates symbols from images in the designated folder into current document
// Author : Oscar Rines (oscarrines (at) gmail.com)
// Version : 1.0.0 on 2014-09-21
// Reused code from "Import Folder's Files as Layers - Illustrator CS3 script"
// by Nathaniel V. KELSO (nathaniel@kelsocartography.com)
#target illustrator
function getFolder() {
return Folder.selectDialog('Please select the folder to be imported:', Folder('~'));
}
function symbolExists(seekInDoc, seekSymbol) {
for (var j=0; j < seekInDoc.symbols.length; j++) {
if (seekInDoc.symbols
.name == seekSymbol) { return true;
}
}
return false;
}
function importFolderContents(selectedFolder) {
var activeDoc = app.activeDocument; //Active object reference
// if a folder was selected continue with action, otherwise quit
if (selectedFolder) {
var newsymbol; //Symbol object reference
var placedart; //PlacedItem object reference
var fname; //File name
var sname; //Symbol name
var symbolcount = 0; //Number of symbols added
var templayer = activeDoc.layers.add(); //Create a new temporary layer
templayer.name = "Temporary layer"
var imageList = selectedFolder.getFiles(); //retrieve files in the folder
// Create a palette-type window (a modeless or floating dialog),
var win = new Window("palette", "SnpCreateProgressBar", {x:100, y:100, width:750, height:310});
win.pnl = win.add("panel", [10, 10, 740, 255], "Progress"); //add a panel to contain the components
