is there anyway to access the internal bitmap representation of a movieclip that has its cacheasbitmap property set to true?It would be nice if I could create vector artwork that scaled to the size of the browser and then obtain a bitmap representation of it so that I could then manipulate it on a per pixel basis for some cool visual fx.
View 1 Repliesis it possible to get access to Flash's internal bitmap cache of an object when CacheAsBitmap is on ?
eg, something like:
var bmd:BitmapData = someDisplayObject.getCachedBitmapData();
if (bmd != null)
trace("stoked!");
else
trace("bummer. got to bmd.Draw(someDisplayObject) ourselves.");
So, I want to create an effect such that each frame I :
1 ) create a bitmap representation of the stage.
2 ) reduce the bitmap's alpha to .75
3 ) remove any currently existing bitmap from stage
3 ) add new bitmap to stage.
If I'm correct in my thinking, this should effectively create the illusion that the stage is fading over time, as every time you call bitmapData.draw() the bitmap will be set at .75 alpha. This *should* mean that when I apply .75 alpha to the new bitmap that it should effectively result in a new image that is .75 * .75 alpha (.56), then on the next frame again it should be lower still (.42), and on... .31, .23, .17, and so on... But it seems that what's *actually* happening is that the new bitmap always *looks* like it's .75 alpha every frame.
ActionScript Code:
import flash.events.*;
import flash.display.*;
// draw a black box...
this.graphics.beginFill(0x000000);
this.graphics.drawRect(0,0,100,100);
this.graphics.endFill();
[Code] .....
Additionally, I've tried using stage.invalidate and doing parts of this in an Event.RENDER handler, but it didn't work either...
1. I've read that when Bitmap Caching an object, if the objects you are caching are bitmaps that all point to the same bitmapData object, than only one instance is cached and used by the GPU. However, if the bitmap contains a scale, does this hold true, or is a new bitmap cached for each object because of the new scale? I'm pretty sure its the second one, just checking.
2. When using cacheAsBitmapMatrix, I've seen examples setting the matrix to identity, and setting it to the concatenated matrix of the bitmap object. Can someone explain the difference between the two approaches? I would assume setting it to identity doesn't scale it up or down when caching is as stated in the documentation:
"The matrix transformation you apply to the cacheAsBitmapMatrix property is applied to the display object as it isrendered into the bitmap cache. Thus, if the transform contains a 2x scale, the bitmap rendering is twice the size of thevector rendering. The renderer applies the inverse transformation to the cached bitmap so that the final display looks the same."
But if this bitmap is nested in a sprite that moves throughout the scene, will the bitmap still move with it? Or will I need to update the matrix's x/y everytime I update the sprite's x/y. If this problem exists, does using the concatenated matrix get around it.
3. Finally, I have seen some sites state that more gpu memory is used when cacheAsBitmapMatrix (such as an additional copy of the texture being pushed into the gpu), but I was under the impression that this would just rotate and scale the texture in memory using openGL matrices. Why would more gpu memory be used when cacheAsBitmapMatrix is set?
My understanding is that when designing for mobile, if the graphic isn't too large, and the object doesn't contain nested animating objects, the best approach is to cacheAsBitmap and cacheAsBitmapMatrix on the object to ensure it won't be pushed to the gpu each frame, but feel free to correct me if I'm wrong. Adobe states "Always set the cacheAsBitmapMatrix property whenever you set cacheAsBitmap to true in content created for mobile devices."

View 2 RepliesI am developing an application with Flex for the GUI and Restlet for the webservices. I have a strange problem. I put my XML as a property on a generic object, and send it as part of a POST request. But in the Restlet webservice, this XML is irretrievable. How do I retrieve it? I tried initialising the received Representation object to a DomRepresentation, but thats not working. If I put the received Representation object into a Form object, then getFirstValue is returning that XML as a string! I noticed that the contentType of the HTTPService was application/www-form-encoded so I set it to application/xml and its not helping either.

View 1 RepliesIm really struggling with controlling a movieclip (frame-by-frame images w/ stop(); actions) by using the mouses horizontal position on the main stage. So basically I want to turn my stage into a showreel of images. Lets say the stage is 50 pixels; i would want some kind of code that would divide up the total length of my m/cs timeline, in order to show the first frame of the m/c when the y-axis is at 0, the last keyframe of the m/c when the y-axis = 500.
I have tried to use rollover commands on (miniscule) hit states covering the entire stage, but there must be a better way ( i plan on updating the images m/c a lot) ie. a lovely big chunk of confusing code?
I am completely new to using Flash and AS, so I decided to start off with something that seemed simple enough, rotating an image. Turns out it's anything but simple. My initial idea was simply to have two layers, on one of which I had the image I wanted to rotate, and above that some other image that was transparent. I've had lots of problems with this but I have managed to hack my way through to some solutions. I would like for someone to confirm if I have understood these solutions correctly.
One problem was that I implement my images (which were BMP at first but now GIF) as Bitmap, and they sit in the library and on stage, so they're visible when I run my Flash movie. However I had problems figuring out how to access the rotation property of my Bitmap, and what I ended up figuring out is that apparently even if it's loaded on the stage and in the library, it can't be used by AS as such. So I ended up having to use Linkage and making a SkyClass, which I then use to make a Sprite, which I can then change the orientation of. But is that really how I have to access my Bitmap, even if I put it on the Stage designtime?

Is there a way to write a UTF-16 string into a ByteArray in Flash/AS3? Basically I have a string (var test:String="allan"; for example) and I would like to write that into a ByteArray with UTF-16LE encoding. In this case it would be "61 00 6C 00 6C 00 61 00 6E 00".
I've tried using utf16le.writeMultiByte( clipText, "utf-16" ); but it just comes out with what appears to be UTF8 (or just straight ASCII given the test string).
The use case is to save a UTF-16LE file using FileReference.save(), which I understand I can do by passing it a ByteArray with the correct character encoding in it. Passing just a string saves as UTF-8. Hence the need to convert and store into a UTF-16LE representation in a ByteArray.
I'm writing a simple little test app consisting of 'main.as' and 'test.png', both within the same subdir on my harddrive. I'm compiling via command line with mxmlc, and testing via 'open with...' and Chrome. The code uses flash.display.Loader.load( "test.png" ) - but I can't access the loaded content (or even draw it to a bitmapdata!) due to security exceptions.
My goal is to get the image into something (preferably a bitmapdata!) I can draw to other bitmapdatas, as I understand this is fastest for gaming. I've tried all sorts of things, including creating a 'crossdomain.xml' that goes in the same dir as the above files (and doing the appropriate LoaderContext thing), tried various system.Security things and still no joy.
I am working on a software which takes .ppt as its input and produces .swf file as its output.
When I was dealing with fonts, I found there is slight difference between the representation of the text in .ppt and .swf though the font name and size are same in both.
The difference increses when I make the text bold or italic or both.
I want to know why such differerence exits?
And what should I do to make the.swf font representation same as that of .ppt?

View 1 RepliesI have some objects that are very, very likely to be equal. I'm comparing them every second to check if they're the same as one stored in a data model on the client.Instead of having to check 5-6 data points to make sure they're equal, I would like to compare the binary to tell if they're not equal, so I can quickly overwrite the object in the collection if they do not have an identical binary representation.for example, I have the following objects:
ActionScript Code:
class tag{
var xCoord;
[code]....
So, instead of doing this sort of comparison for every member in the class
ActionScript Code:
if ( tagOne.xCoord != tagTwo.xCoord ){
swapTagsInCollection (tagOne, tagTwo);
}
I would like to do something like this.
ActionScript Code:
if ( tagOneBinary != tagTwoBinary ){
swapTagsInCollection (tagOne, tagTwo);
}
I have some data in collection from which i have to create hierarchy diagram in Flex.
View 1 RepliesMy program saves text files, which contain various text, some of which is a string representation of a ByteArray. It does this by using the toString() method of the flash.utils.ByteArray class, which I assume converts a ByteArray (for example, 13x$) into its string representation "13x$". So how do you reverse the process, and turn the string ("13x$") into a ByteArray (13x$)? Even if it's not that simple, I just need to have the ByteArray, put something in a text file, and extract from it the same ByteArray.
View 1 RepliesI'm looking for a fail-safe way to round-trip between a Flash swf file and a text representation and back again. One strict requirement is that the resulting round-tripped Flash swf file is exactly functionally equivalent to the original Flash swf file as long as the text representation is left unchanged. Furthermore, the text representation must be human-readable and editable. It should be possible to make small changes to the the text representation (such as changing a text string or a class name, etc.) which are reflected in the resulting class file representation. Is there a fail-safe way to achieve Flash swf file/text-representation/Flash swf file round-tripping given the requirements above?
