Actionscript 3 :: Create Image Preview Using Flex?
Aug 6, 2011
I am working on flex image uploader.as soon as you select images I am showing the image name, size. I want to show the thumbnail of the image too..so that you can preview the image before uploader.
I have added the code which I am using to show preview before upload..
My embedded images show up in the Flex Builder Design Preview, but are not displayed when the application is run. The images have relative paths (/assets/images/...), and the application is run on the server (wamp). I've appended the path to the compiled location [URL] and tried to display a image in the browser, and the image exists, too. I've compiled it via FlashDevelop, Flex Builder, and Ant. I've deleted and remade the bin/bin-debug/release/bin-release files to no avail.
I have found something good here. [URL]..The mouseover effect on the list item is good. Any ideas to make this look.. I can infer that this is happening on mouseover of the Image Component. I think this is similar to google image search preview of images. If anyone have come across a component similar to this kindly share it to me and to all.
I am trying to make a web page similar to the link below...where when a customer types in the form text field, and simultaneously, the text will preview in another area of the webpage over and image. See example when you create a label[URL]
My searches have led me into some overcomplicated solutions. I'm using Flash to create a simple .swf that contains a movie with subtitles. I'm sure there are better ways but this is the easiest and I have been too long gone from developing in Flash and uBer rusty.
I used the movie importer, added captions exported my movie. All works great. The movie is set to NOT auto-play though and fades in from black so when the user first sees it they just see the skin and a black box. What I would like to do is have a preview image appear instead of the black first frame until the user plays the movie.
I have been hunting for quite some time now and I can not find anyone that knows how to create a preview image for an FLV. I.E. youtube, they show you a part of the clip you are about to watch and not the first frame.
I have found a nice free flash template to use for a portfolio site but I want to add something small to it but could not figure it out myself.The free templates creates a thumbnail preview of the image and I want to be able to create a full size preview off in another area. I will post the AC3.0 and an image to explain.
LIke youtube, they have a preview image of the flash video.How do i get flash using actionscript to dynamically generate a image realtime? how do i convert any file to an flv through the internet? dont worry, i'm not trying to beat youtube,i'm doing this for a music studio website. I heard of this ffmpeg.exe....how to use this? Do I put this on my webserver? I use the paid yahoo webhosting.

I'm looking for some flash based plug-in which allows me to display an image as soon as the user selects it in the file dialog.I looked at swfupload but couldn't find any way to display the image selected.. no handle on file path or contents as far as I could find.
I have FLV video component waiting for the user to push play. However, I want a thumbnails that I can stick in there because it is just black. How does this work with the FLV playback component? I can't find anything about this.
function previewLoaded(e:Event):void { var previewArea:MovieClip = new MovieClip();
[Code]....
This coding is located inside another movieclip because I'm trying to have a mouse over show a different preview area in another area of the flash. It's as if the movieclip isn't being recognized but I just can not figure out how to get it to work. I've been on this problem for 5 days and I would really like to get my website up and running.
I saw this tutorial and it works great in actionscript 3.0 on its own - http:[url].... .But does anyone know to make something like this in actionscript 2.0? The reason being is my main site was created in 2.0 and cannot publish it in 3.0.
I'm having a problem with component live previews. If I just create a movie clip and set the live preview, all instances of the clip i put on stage update separatly from each other (their live preview that is). As soon as I change the clip to a component (export .swc or compiled clip) all the instances update together. eg if i set the component parameter 'title' - all titles of the all the instances on the stage will change. This didn't happen when it was just a movieclip - all instances changed separatly as i set them.
It seams no matter what publish settings I use the image quality of JPGs in my flash movie is poor (see linked image) Am I missing a setting? how do you get really crips, clean, beautiful image preview in Flash?
I have created an application which includes a menu system for selecting videos and a video player. Currently when the application opens the flv player video starts on load. I would like to change this to show a preview image which would not disappear until my users click on a button to view a video.I have tried to use the preview image function in the flv player and received this error:"The preview image is displayed at authoring time only. To generate a runtime preview image, use the export button and load the image back by writing your own ActionScript.
I have some 3rd party Flash SWFs on my site that are up to 100KB in size. e.g. the Flash video player "JWPlayer" SWF is 98KB.
That's fine for people with Broadband, but not so good for the slow dial up bandwidth visitors. e.g at 40 kbits/s, we're talking 20 seconds to download.
The problem is that on slow connections, all the visitors are seeing is a static white screen, and so may close the page thinking it's dead. If I right click the area where the SWF is to go, an Adobe Flash Player Object is occupying the space, but the 3rd party SWF has not finished loading in yet.
I would like the website visitors to see a loading spinner GIF or something similar.
Unfortunately, none of the 3rd party SWFs have "preloader" element. And they are not open source, so I cannot add a preloader to them.
Is there any way to display a loading image, prefereably a GIF animation, while the SWF is loading?
For example, is there any way to force the Adobe Flash Player to show an image while it is loading in the SWF?
I don't have any Flash coding skills, so a solution that doesn't include creating an extra SWF or a SWF within a SWF would, probably isn't best for me, but might be worth adding to the post in case other people have a similar problem.
i am trying to get a preview image to appear when using the flvplayback component. it does not show up within the flash player or when i test on a server. i was able to use the component inspector to find the image i wanted and export and save it. i saved the png file in the same directory where my flv is located. here is my AS:
Code: Select allimport fl.video.FLVPlayback; var flv_video_mc:FLVPlayback = new FLVPlayback(); flv_video_mc.source = "flv/video.flv"; flv_video_mc.preview = "flv/video_preview.png";
I'm having some trouble with getURL (I think). It works fine when I preview with Flash's html preview but it's not working on my server. It's pretty simple. [URL].selected1 is a user-defined variable pointing to a page: ie, when the user selects variable page1 the page to be opened is [URL]. Like I said, it works with Flash's preview, but not on my server(no 404 or any response). Does there seem to be a problem with my code or might I be overlooking a server error? Here's my code:
I've been customizing the flvplayback component and have run into a problem. So far I have successfully created a custom skin for the flvplayback component, with a play overlay button,which loads the FLV dynamically from flashvars.I am now trying to load in a static image which appears until the video is played.I've been looking around the internet and in the Adobe forums, but haven't found what I'm looking for.I thought perhaps the Preview min the AS3 flvplayback component would help, but this won't work apparently.
I was thinking myPlayer.source = "image.jpg"; but then how can I change what the source is once someone clicks on the video? I also found fl.video.VideoEvent, but I'm not sure how I can use this to set the image as the source, until someone presses the play button, or until the video is playing (note that I am using an overlay play button which shows up whenever the movie is paused, so once the video starts playing, I would not want the static preview image to come up again...just until someone clicks the any play button).
I cannot find an ActionScript 3 code example anywhere on how to load a PNG file as a flvplayback preview image and add it in at runtime." Assigning the preview property with the string of the PNG file refrence like 'video.preview = "previewimg.png"' does nothing. who to assign in ActionScript 3 a PNG file as preview file.
I hope I am placing this question in the right forum. I have searched everywhere trying to find the answer..
I am using Dreamweaver CS4 to insert a FLV video into a web page. Dreamweaver automatically uses FLVPlayer as the flash player. All is working beautifully except that when I first visit my web page, the video area is just a black screen. I would like to put a preview image there instead. Other players just seem to usually have a parameter that you set like "image=" and you point to the .jpg or whatever, but I can't get that to work here.
I can't believe I am having this much trouble, and this must be a super simple answer. [URL]..
I am creating a video player that sets up a preview image before it begins to play. If I set the preview image in a loader within a container it works, except if I change the size of the preview.jpeg that is being loaded into it. It loads the image into the loader, within the container, but then scales the container making the image smaller than I need. I want it so that the preview.jpeg can be made by anyone at any size and the image be scaled to sit over the video. Unless the vidWidth and vidHeight are equal to the preview.jpg the image doesnt show up, just blank ??
Code: var vidWidth:Number = 300; var vidHeight:Number = 240; var preview_Loader:Loader = new Loader(); var preview_URL:String = "preview.jpeg"; var preview_Request:URLRequest = new URLRequest(preview_URL); [Code] .....
returns: ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. This only happens when I try to set the index of the preview_Loader? I need it to be the second mc from the bottom. I set up 2 functions to load the image. The first doesn't allow smaller images to be loaded into the container and make them the correct size. While the second makes them dissapear if I change the size.
I am having a very difficult time trying to setup and flash file that has a scrolling menu (mouse movement scrolls the menu up or down). This menu can expand to menu & submenu and it is working fine. What I need is to make an AS file that can load images to a preview window inside the same fla file. ADSK2009 [URL] Attachments: ADSVertMenu.zip (29.8 K)
Does anyone know what criterea Flash uses for discovering the Live Preview class for a Component? Background We are attempting to automate the creation of a SWC that contains a component to be used from Flash. We are able to make it visible to flash by modifying the manifest.xml and wiring up the component definitions. However, the component cannot be dragged onto the stage (or library), presumably because it has no form of LivePreview. To give better clarification of where we are coming from, we've noticed the following in SWCs exported from Flash (using swfdump):
fl.livepreview.LivePreviewParent contains the same mod attribute as the visual component in the manifest.xml file fl.livepreview.LivePreviewParent is exported as a symbol The short-named component (ie. no package, referenced in the components definition in the manifest.xml) is exported as a symbol However, I can see no other differences between that and the SWC from Flex. We can obviously use JSFL to perform the task, but we'd rather not install Flash on the build server.
I need dinamicaly create LinkButton with icon. The names of files (icons) have the format "images/icon_0.png","images/icon_1.png", ... "images/icon_1000.png". But I don't know specific image for this button. I know only index of icon.I tried this, with no success:
var path:String = "@Embed(source='images/icon_" + imageindex + ".png')"; myButton.setStyle("icon", path); I get a runtime error Type Coercion failed:
