I wants to change image from bg composition through extendscript. Reason behind this, is to reduce time to every time to go into pre-comp(BG) and manually change image.
I have tried to modify "Smart Import.jsx"(provided with AE), but this script is specially for image sequences. And modified script is not working me
function myImport()
{
var targetFile = File.openDialog ("Import your file", "*.jpg", multiSelect = false);
function processFile(theFile)
{
try {
var importOptions = new ImportOptions(theFile);
importSafeWithError(importOptions);
} catch (error) {
}
}
function processFolder(theFolder)
{
var files = theFolder.getFiles();
var sequenceStartFile = testForSequence(files);
}
processFolder(targetFile);
}
myImport();
}
I am expecting to import an image not only to the project library, but also it needs to be added into bg comp to change bg.
You can change the source of an existing file and this will effect all comps that use that file. Source files in the project window are footageItem objects and they have an attribute called mainSource which is a file object. So simply change the mainSource attribute of the bg footage. More in the docs here.
Here in this script, after click on 'Import File' button, I got required result.
var selComp;
for (var i = 1; i <= app.project.numItems; i ++)
{
if ((app.project.item(i) instanceof CompItem) && (app.project.item(i).name === 'MOVIE IMAGE')) {
selComp = app.project.item(i);
}
}
selComp.openInViewer(); // View Your Comp opened in after effects
{
var w = new Window ("dialog");
var importFile = w.add ("button", undefined, "Import File");
importFile.onClick = ImportFile ;
importFromFolder.onClick = ImportFilesFromFolder ;
function ImportFile () {
app.beginUndoGroup("Import File");
var targetFile = File.openDialog("Import File");
if (targetFile) {
var importOptions = new ImportOptions (targetFile);
var newLayer = app.project.importFile (importOptions);
var insertLayer = selComp.layers.add(newLayer);
}
$.writeln(newLayer.name);
app.endUndoGroup();
}
w.show ();
}

In AS3 I could write the following:
fileReference = new FileReference();
var xmlStage:XML = new XML(<STAGE/>);
var xmlObjects:XML = new XML(<OBJECTS/>);
var j:uint;
var scene:SomeScene = ((origin_ as SecurityButton).origin as SomeScene);
var object:SomeObject;
for (j = 0; j < scene.objectArray.length; ++j) {
object = scene.objectArray[j];
if (1 == object.saveToXML){
var item:String = "obj";
var o:XML = new XML(<{item}/>);
o.#x = scene.objectArray[j].x;
o.#y = scene.objectArray[j].y;
o.#n = scene.objectArray[j].name;
o.#g = scene.objectArray[j].band;
o.#f = scene.objectArray[j].frame;
o.#w = scene.objectArray[j].width;
o.#h = scene.objectArray[j].height;
o.#s = scene.objectArray[j].sprite;
o.#b = scene.objectArray[j].bodyType;
xmlObjects.appendChild(o);
//System.disposeXML(o);
}
}
xmlStage.appendChild(xmlObjects);
fileReference.save(xmlStage, "XML.xml");
//System.disposeXML(xmlObjects);
//System.disposeXML(xmlStage);
//fileReference = null;
Is there an equivalent way to do this in Haxe? (Target of interest: HTML5)
If not, what are my options?
(The exported results of this code in AS3 are shown in this link below)
https://pastebin.com/raw/5twiJ01B
You can use the Xml class to create xml (see example: https://try.haxe.org/#68cfF )
class Test {
static function main() {
var root = Xml.createElement('root');
var child = Xml.createElement('my-element');
child.set('attribute1', 'value1'); //add your own object's values
child.set('attribute2', 'value2'); //may be add a few more children
root.addChild(child);
//this could be a file write, or POST'ed to http, or socket
trace(root.toString()); // <root><my-element attribute1="value1" attribute2="value2"/></root>
}
}
The root.toString() in that example could be instead serialized to a file File, or indeed any other kind of output (like POSTing via http to somewhere).
You could use FileReference for flash target, and sys.io and File for supported targets:
var output = sys.io.File.write(path, true);
output.writeString(data);
output.flush();
output.close();
I need to get size of image that I just added to stage and set it to defaultX and defaultY before I call the autorenderer, but I can't seem to grab the size.
How do I grab the size?
Also, from what I got so far, I think the best way to set the size is including with autorenderer. But what would be the implication here if I resize() later?
Any help will be appreciated. Thank you.
my code:
this.stage = new PIXI.Container();
var texture = PIXI.Texture.fromImage('background.png'); //1610x640
var spr = new PIXI.Sprite(texture);
this.stage.addChild(spr);
defaultX = texture.width;
defaultY = texture.height;
this.renderer = PIXI.autoDetectRenderer(defaultX, defaultY); //640x690
this.renderer.resize(x,y); // I know this works with other values
// eg if I hardcode with 1610,640
// but texture.width doesn't work and
// I don't want to hardcode it
Your image can not be loaded when you call texture.width.
I use next construction:
this.stage = new PIXI.Container();
this.renderer = PIXI.autoDetectRenderer(640, 690); //640x690
var baseTexture = new PIXI.BaseTexture('background.png');
// can be loaded from cache
if (baseTexture .hasLoaded) {
createSprite(baseTexture);
} else {
baseTexture .on('loaded', function() {
createSprite(baseTexture); // or this
});
}
function createSprite(baseTexture) {
var texture = new PIXI.Texture(baseTexture);
var spr = new PIXI.Sprite(texture);
this.stage.addChild(spr);
defaultX = texture.width;
defaultY = texture.height;
this.renderer.resize(defaultX,defaultY);
}
function clickButtonHandler(event:MouseEvent):void
{
var message:Object = new Object();
message.text = txtMessage.text;
message.userName = txtUser.text;
//Posts to this swf
showMessage(message);
//Posts to ALL OTHER swf files..
group.post(message);
}
function showMessage(message:Object):void
{
output_txt.appendText(message.userName+": "+message.text + "\n");
}
function jsalertwindow(event:MouseEvent):void
{
var alert:URLRequest = new URLRequest("javascript:alert('Please enter your User name')");
navigateToURL(alert, "_self");
}
As you can see there are two function which are contain mouseevent. I want to send those function with an if-else statement. If user write something in text input component which name is txtUser and,
send_btn.addEventListener(MouseEvent.CLICK, clickButtonHandler);
will work, else(if the user forget writing anything)
send_btn.addEventListener(MouseEvent.CLICK, jsalertwindow);
will work.
And one more question should i use MouseEvent.CLICK or MouseEvent.MOUSE_DOWN? Thanks for your advice.
Assign a single handler to the button click (MouseEvent.CLICK is the right event to use) and check the field is populated in the handler:
function clickButtonHandler(event:MouseEvent):void
{
var message:Object = new Object();
// Check the field is populated
if (txtUser.text != "")
{
message.text = txtMessage.text;
message.userName = txtUser.text;
showMessage(message);
//Posts to ALL OTHER swf files..
group.post(message);
}
else
{
// Nothing in the input field, show the alert
showAlert();
}
}
function showMessage(message:Object):void
{
output_txt.appendText(message.userName+": "+message.text + "\n");
}
function showAlert():void
{
var alert:URLRequest = new URLRequest("javascript:alert('Please enter your User name')");
navigateToURL(alert, "_self");
}
I am trying to perform a special action whenever the user double clicks any object located inside the canvas. I have read the docs and not found any mouse:dblclick-like event in the documentation. I tried doing something like:
fabric.util.addListener(fabric.document, 'dblclick', callback);
Which does trigger the dblclick event but does not give specific information about the actual object that is being clicked on the canvas.
Any ideas of the most FabricJS-y way of doing this?
The more elegant way is to override fabric.Canvas._initEventListeners to add the dblclick support
_initEventListeners: function() {
var self = this;
self.callSuper('_initEventListeners');
addListener(self.upperCanvasEl, 'dblclick', self._onDoubleClick);
}
_onDoubleClick: function(e) {
var self = this;
var target = self.findTarget(e);
self.fire('mouse:dblclick', {
target: target,
e: e
});
if (target && !self.isDrawingMode) {
// To unify the behavior, the object's double click event does not fire on drawing mode.
target.fire('object:dblclick', {
e: e
});
}
}
I've also developed a library to implement more events missed in fabricjs : https://github.com/mazong1123/fabric.ext
This is similar to #LeoCreer's answer but actually gets access to the targeted object
fabric.util.addListener(canvas.upperCanvasEl, 'dblclick', function (e) {
var target = canvas.findTarget(e);
});
The Correct way to add custom events to Fabric.js
window.fabric.util.addListener(canvas.upperCanvasEl, 'dblclick', function (event, self) {
yourFunction(event);
});
or use fabric.ext
I'm using this workaround:
var timer = 0;
canvas.item(0).on('mouseup', function() {
var d = new Date();
timer = d.getTime();
});
canvas.item(0).on('mousedown', function() {
var d = new Date();
if ((d.getTime() - timer) < 300) {
console.log('double click')
}
});
Here is a quick and easy way to add a double click event handler to Fabric JS -
Include following code snippet to your html file. Just ensure this is loaded after the main fabric.js library
<script type="text/javascript">
fabric = (function(f) { var nativeOn = f.on; var dblClickSubscribers = []; var nativeCanvas = f.Canvas; f.Canvas = (function(domId, options) { var canvasDomElement = document.getElementById(domId); var c = new nativeCanvas(domId, options); c.dblclick = function(handler) { dblClickSubscribers.push(handler) }; canvasDomElement.nextSibling.ondblclick = function(ev){ for(var i = 0; i < dblClickSubscribers.length; i++) { console.log(ev); dblClickSubscribers[i]({ e :ev }); } }; return c; }); return f; }(fabric));
</script>
Then add this code to listen a double click event:
canvas.dblclick(function(e) {
});
To get information about the actual object that is being clicked on the canvas, use following method -
canvas.getActiveObject();
eg.
canvas.dblclick(function(e) {
activeObject = canvas.getActiveObject();
});
I am late but now fabricjs has mousedblclick event.

I'm playing with MonoTouch.Dialog and written some code to show some tweets. The problem is that the table cells are too small and the cells are all bunched up when I load the StyledMultilineElements asynchronously. They look absolutely perfect when I load them synchronously (i.e. without the QueueUserWorkItem/InvokeOnMainThread part)
Is there a way of getting the table cells to recalculate their height?
// This method is invoked when the application has loaded its UI and its ready to run
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
window.AddSubview(navigation.View);
var tweetsSection = new Section("MonoTouch Tweets"){
new StringElement("Loading...") //placeholder
};
var menu = new RootElement("Demos"){
tweetsSection,
};
var dv = new DialogViewController(menu) { Autorotate = true };
navigation.PushViewController(dv, true);
window.MakeKeyAndVisible();
// Load tweets async
UIApplication.SharedApplication.NetworkActivityIndicatorVisible = true;
ThreadPool.QueueUserWorkItem(delegate {
var doc = XDocument.Load("http://search.twitter.com/search.atom?q=%23MonoTouch");
var atom = (XNamespace)"http://www.w3.org/2005/Atom";
var tweets =
from node in doc.Root.Descendants(atom + "entry")
select new {
Author = node.Element(atom + "author").Element(atom + "name").Value,
Text = node.Element(atom + "title").Value
};
var newElements =
from tweet in tweets
select new StyledMultilineElement(
tweet.Author,
tweet.Text);
InvokeOnMainThread(delegate {
UIApplication.SharedApplication.NetworkActivityIndicatorVisible = false;
tweetsSection.Remove(0);
tweetsSection.Add(newElements.Cast<Element>().ToList());
});
});
return true;
}
Try setting the UnevenRows property on your top level Root element of your Dialog View Controller, in this case "menu":
menu.UnevenRows = true
