ActionScript 2.0 :: Convert MC To Bitmap For BG Tiling?
Jan 25, 2009
I'm building an XML driven video player that will allow users to customize a wide variety of layout/visual features for the player, and one of the important features is letting them switch between a regular background image, and a tiled background. I've been playing around with various methods for tiling using the Bitmap class, and its been working fine, as long as I load the image from the library. However, when I try to load the image dynamically (i.e. through XML), it doesn't jibe.
Here's the code for the tile:
function tile() {
var tile:BitmapData = BitmapData.loadBitmap("linkageIDForBitmap");
this.beginBitmapFill(tile);
this.lineTo(Stage.width, 0);
[code]....
Again, if I write a variable which references the xml node, and use that variable in the loadBitmap function, it doesn't work. I'm assuming this is because the dynamically loaded tile doesn't have a linkage ID attached? Not sure how to do that...
My other thought is to simply load the tile into a movieclip (as I do with all the other content), and then convert the movieclip to a bitmap, then proceed as normal with the code above. I've searched the boards for a method to do this, but have come up empty.
if it is possible to covert a bitmap to a Sprite? I tried casting it to a sprite, but that does not work. The reason why is because if figured out that you can't use the addChild option on a bitmap.
Apparently, in order to make a bitmap transparent, one has to convert it to 256 colors from 24. I'm not sure if Flash puts it in 24 or 256, but because I can't create a transparency when using Bitmap() in my code, and from what I see displayed on the screen, it would appear that it uses 24 colors. Perhaps this is to keep things light. Nonetheless, is it possible to convert it to 256 colors?
Is there any example of passing bitmap data into iOS and returning a modfified copy. I am trying to convert a bitmap into jpeg - similar to this example in Windows [URL] but it crashed every time. P.S. Below is my attempt:
and the error message is: Error: Error #2030: End of file was encountered. The situation is i have store the image as binary into the database by convert the byteArray and now i would like to retrieve it and convert back to image.
Just to clear this up ByteArray Need to Place into Bitmap and then you can add to the movie Clip right?
I am having a few issues converting a MC to a bitmap. I have succeeded in loading a graphic from the library, loading that as a bitmap and I can use getPixel to get the color at a certain x,y point.BUT I have another part to the problem. I have a file upload where a user can upload an image and choose a color off that logo. So I have the logo uploading, then getting loaded into an MC on the stage and it all works honky dory.However, when I (thought) I was converting it to bitmap and then use getPixel, every part of it is just returning white.[code]But no matter what co-ordinates I put in, I always get white.
var myBitmapData:BitmapData = new BitmapData (612, 792); myBitmapData.draw(STData_mc); bm = new Bitmap(); bm.bitmapData = myBitmapData; stage.addChild (bm);
these are my code. I have a movieclip named STData_mc, first I want to use var myBitmapData:BitmapData = new BitmapData (STData_mc.width, STData_mc.height); but it bring me an error. so I changed like this. but this is ok. Finally, when I add "bm" to the stage, there is nothing, just a white space.
On my stage I'm playing a flv video. There's a button over the video that when clicked draws the stage to a bitmap. The bitmap is then converted to a jpg and downloaded to the viewer. It all works great except that I have open with photoshop then save as jpg to get a useable jpg image. If possible I would like the download to be viewable by most photo viewers without having to open with phothshop. here's what the output looks like:[URL] here's the code I use to handle the mouse click:
I've seen mention of there being some security risk with loading images and leaving them in loaders. A few articles I've run across said that you should always draw them as a bitmap when the loading is done.
Is there any truth to this? I have a few loaders I have left in my project, do I need to hand their content off to a bitmap? What is the advantage of always having a bitmap represent the loaded image?
I've got a MovieClip which has bitmaps pasted onto it via AS3. These bitmaps are transformed and are sometimes over each others with transparency.So I would like to the grab the whole MovieClip as it is and make it a completely new bitmap. Problem is:
ActionScript Code: bitmapData.draw(mc) //does NOT work in this case (nothing shows) bitmapData.draw(mc.getChildAt(0)) // works, but it doesn't save the childs properties such as x,y coordinates and transparency
What I need is basicly a function such as "Image -> Apply Image" in photoshop.Except that it only copies a movieclip and not whole stage.
I'm currently working on a flash project that creates a lot of instances(small boxes) and puts them on the stage, this will lag significantly after a while, and I thought there would be a way to draw these boxes to a bitmap object and remove the unnecessary children.
Over the weekend i put together an MP3 player in Flex and just managed to figure out the SoundSpectrum.
It is working as expected.
I am facing problems when it comes to using a bitmap.
Right now, my "Analyser" class pulls the data from SoundMixer.computerSpectrum.
I then use that data with the drawing API to create a simple analyser. You know, just spikes.
Here is the code for that part:
Code: private function update(e:TimerEvent): void { SoundMixer.computeSpectrum(ba, true); var n:Number = 0;
[Code]....
Ok using common sense here, I am telling flash to take a snapshot of the Analyser and draw it to the bitmapData.
However, i cant seem to get this working. I am not using the dispose() method to clear the bitmap so id expect to see a mess of points (similar to if i removed the g.clear()) but nothing happens.
why I cannot convert a loaded jpeg to a bitmap.I've found similar posts on this forum but the solutions provided are not working for me. I have a very simple example of what I'm trying to do below:
Code: private function loadImage():void { var imageLoader:Loader = new Loader();[code]...
For whatever reason I get the error:
Code: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Bitmap@3a0926d1 to Function.at com.ncnmar.interphaz::People01/loadedImage()
I'm making a game where the player moves around a map, where the player can walk and where they can't is decided by the color of the pixel they are trying to move onto, which I get using the Bitmap.getPixel method.
What I'd like to do though is when the map image is loaded process it into a sprite or something which I can then use the DisplayObject.hitTest methods on. So I have an array of colors whcih the user can walk on, is there way I could go through each pixel and build something that would let me do that?
The solution should be straight forward but I cannot find it, my problem it's that I'm reading a xml, and one of the properties inside the xml it's a Bitmap path(string), when I`m reading this xml I would like to convert this string to a Bitmap Obj so I can use through my MXMLs.
What I have so far is a carouselmenu. I got a actionscript page (page1.as) where I load another one (page2.as) into. page2.as is a Sprite (or MC whatever). I can load and display the sprite in page1 successfully (several instances). I also have an eventhandler when i click on an instance of page2. The problem now is that I have defined a textField inside page2 that is also being displayed. What's not working here is that when I mouse over the text, I cannot click on it (the cursor turns into the cursor that appears when I mouse over a text as in MS Word or similar for being able to mark the text). So I thought of making a bitmap out of the text field. how to transform a text(field or string) into a bitmap?
I am developing some Text effects in AS3. I did complete curve text effect but are getting problem with bulge text. Because bulge text distort each characters so i have to convert the text to bitmap format to distort. The problem is the quality is not good enough, especially when we resize the object. I see in some websites they solved this issue and it works pretty good, like as [URL].
It works great, but because I'm publishing my SWF with noScale at 100% width and height, the background doesnt fill the whole swf, only the size of the actual stage in the FLA. Is there any way I can change this so It will fit accordingly?
I know I can convert a mc to a bitmap with "cacheAsBitmap".Now I am wondering how I can convert a bitmap to a mc.I have a black and white bitmap, which I created from a vide still.now I would like to convert the white area of this bit map to an mc,so that I can used it for hitTest etc.
I've seen the Full Browser Flash video which has tiling in the background. Can somebody supply code, and possibly an example of how to have one scalable image as the background without distortion whilst the foreground flash remains the same size. the site below is exactly what i'm after with the menu fixed to the left.
[URL]
Is it also possible to have the menu bar a fixed percentage from the top of the browser?e.
I've seen a lot of posts on how to tile an image in a Flash movie that is being scaled to fit the browser. I found some code posted a while back to do it in MX 2004. (below) Can someone tell me what parts of this don't work in Flash MX? (I don't have 2004) Can this be adapted to work in Flash MX, or does someone know another way to achieve the desired result in MX?
