illustrator插件-画板功能开发-插入页码-js脚本开发-ai插件

1.算法程序

  illustrator是矢量编辑软件，画板是绘制处理的重要容器，开发一个插入页码功能，源代码如下所示：

if (app.documents.length > 0) {
    var win = new Window("dialog", "插入日期文件名变量页码");
    var panelMargins = win.add("panel", undefined, "边缘");
    var lblMargins = panelMargins.add("statictext", undefined, "距离边缘:");
    var txtMargins = panelMargins.add("edittext", undefined, 0.25);
    var lblUnits = panelMargins.add("statictext", undefined, "inches");
    var panelLocation = win.add("panel", undefined, "位置");
    var radTop = panelLocation.add("radiobutton", undefined, "顶");
    var radBottom = panelLocation.add("radiobutton", undefined, "底");
    var panelAlignment = win.add("panel", undefined, "对齐");
    var radLeft = panelAlignment.add("radiobutton", undefined, "左");
    var radCenter = panelAlignment.add("radiobutton", undefined, "中");
    var radRight = panelAlignment.add("radiobutton", undefined, "右");
    var panelFooter = win.add("panel", undefined, "插入的类型");
    var grpPages = panelFooter.add("group");
    var btnPage = grpPages.add("button", undefined, "页码");
    var btnPages = grpPages.add("button", undefined, "总页");
    var btnDate = grpPages.add("button", undefined, "日期");
    var btnTime = grpPages.add("button", undefined, "时间");
    var btnFullName = grpPages.add("button", undefined, "地址");
    var btnFile = grpPages.add("button", undefined, "文件名");
    var txtFooter = panelFooter.add("edittext");
    var btnClear = panelFooter.add("button", undefined, "取消");
    btnPage.size = btnPages.size = btnDate.size = btnTime.size = btnFullName.size = btnFile.size = btnClear.size = [31, 24];
    var btnOk = win.add("button", undefined, "Ok");
    radRight.value = radBottom.value = true;
    win.alignChildren = panelFooter.alignChildren = "fill";
    btnClear.alignment = "left";
    panelMargins.spacing = 3;
    panelMargins.orientation = panelLocation.orientation = panelAlignment.orientation = "row";
    win.helpTip = "© 2012 Carlos Canto";
    btnOk.helpTip = "Press Esc to Close";
    btnPage.helpTip = "Adds *page* keyword, it represents a single page";
    btnPages.helpTip = "Adds *pages* keyword, it represents total number of pages";
    btnDate.helpTip = "Adds *date* keyword, it represents today's date";
    btnTime.helpTip = "Adds *time* keyword, it represents current time";
    btnFullName.helpTip = "Adds *fname* keyword, it represents Full File Name (including path)";
    btnFile.helpTip = "Adds *file* keyword, it represents File Name";
    btnClear.helpTip = "Clears input text area";
    txtFooter.helpTip = "Type \r\t'Page *page* of *pages*' \rto get \r\t'Page 1 of 3' \rfor example";
    var wgx = win.graphics;
    var grayPen = wgx.newPen(wgx.PenType.SOLID_COLOR, [0.67, 0.67, 0.67], 1);
    txtFooter.onDraw = function() {
        var gx = this.graphics;
        gx.drawOSControl();
        this.text || this.active || gx.drawString("[Type text to insert here] Press Esc to close", grayPen, 0, 0);
    };
    btnOk.onClick = function() {
        if (txtFooter.text != "") {
            doSomething()
        }
    };
    btnClear.onClick = function() {
        txtFooter.text = "";
    };
    btnPage.onClick = function() {
        footer("*page*");
    };
    btnPages.onClick = function() {
        footer("*pages*");
    };
    btnDate.onClick = function() {
        footer("*date*");
    };
    btnTime.onClick = function() {
        footer("*time*");
    };
    btnFullName.onClick = function() {
        footer("*fname*");
    };
    btnFile.onClick = function() {
        footer("*file*");
    };
    win.center();
    win.show();

    function footer(page) {
        txtFooter.text = txtFooter.text + page;
    }

    function doSomething() {
        var idoc = app.activeDocument;
        try {
            var ilayer = idoc.layers["Page Numbers"];
        } catch (e) {
            var ilayer = idoc.layers.add();
            ilayer.name = "Page Numbers";
        }
        var pages = idoc.artboards.length;
        var datee = getdate();
        var timee = gettime();
        var fname = idoc.path == "" ? "Full Name: <unsaved document>" : idoc.fullName;
        var file = idoc.name;
        var footerPages = txtFooter.text.replace("*pages*", pages);
        footerPages = footerPages.replace("*pages*", pages);
        footerPages = footerPages.replace("*date*", datee);
        footerPages = footerPages.replace("*time*", timee);
        footerPages = footerPages.replace("*fname*", fname);
        footerPages = footerPages.replace("*file*", file);
        var margins = Number(txtMargins.text) * 72;
        for (var i = 0; i < idoc.artboards.length; i += 1) {
            footerPage = footerPages.replace("*page*", i + 1);
            var itext = ilayer.textFrames.add();
            itext.contents = footerPage;
            var fontSize = itext.textRange.characterAttributes.size;
            var activeAB = idoc.artboards[i];
            var iartBounds = activeAB.artboardRect;
            var ableft = iartBounds[0] + margins;
            var abtop = iartBounds[1] - margins;
            var abright = iartBounds[2] - margins;
            var abbottom = iartBounds[3] + margins + fontSize;
            var abcenter = ableft + ((abright - ableft) / 2);
            if (radRight.value == true) {
                itext.left = abright;
                itext.textRange.paragraphAttributes.justification = Justification.RIGHT;
            } else if (radCenter.value == true) {
                itext.left = abcenter;
                itext.textRange.paragraphAttributes.justification = Justification.CENTER;
            } else {
                itext.left = ableft;
                itext.textRange.paragraphAttributes.justification = Justification.LEFT;
            }
            if (radTop.value == true) {
                itext.top = abtop;
            } else {
                itext.top = abbottom;
            }
        }
        app.redraw();
    }
} else {
    alert("请打开一个文档");
}

function getdate() {
    var date = new Date();
    var m = date.getMonth() + 1;
    var d = date.getDate();
    var y = date.getFullYear();
    var datemdy = m + "/" + d + "/" + y;
    return datemdy;
}

function gettime() {
    var time = new Date();
    var hours = time.getHours();
    var minutes = time.getMinutes();
    if (minutes < 10) {
        minutes = "0" + minutes;
    }
    if (hours > 11) {
        ampm = "PM";
    } else {
        ampm = "AM";
    }
    var curtime = hours + ":" + minutes + " " + ampm;
    return curtime;
}

2.文本转执行

  使用记事本或者notepad++等文本编辑器，将代码拷贝至文本文件，然后修改后缀名为js或者jsx，最后再illustrator软件菜单文件》脚本》其它脚本，选择脚本文件，点执行即可，也可以将脚本放在预设文件夹内，会显示再脚本下的二级子菜单。如下图所示：
