Why would bitmap outperform vector?My Flash is for a large Kiosk, with rich media requirements and must function accurately as a counter. I want to keep everything vector for scalability. When I did a simple FPS test, I noticed my Bitmap version performed perfectly, and the all vector file was noticeably slower.
- only text and bitmap perform well, not vector
- background and clouds OK, but more layers slow it down
We have some very complex animations that, for performance reasons, we want to have them be bitmaps at runtime..
For example, maybe i can write a jsfl script to copy each frame and paste it into a new .fla as a png instead of as vector art, but I haven't explored that option much.
Let's say I have a 100x100 Sprite() and draw vector art into it with the drawing API. I happen to draw outside the 100x100 dimensions, but the vector art will display anyway. But what if I don't want it to be displayed outside of those dimensions?I know I can mask it and the problem is solved, but I was wondering if there was a way to convert the Sprite() to a bitmap() with bitmapData() where I could copy the 100x100 area from the Sprite to the bitmap. I was wondering if this would be easier on the CPU than masking.I've already tried cacheAsBitmap because I'm using it anyway to speed processing up, but as I figured, it doesn't allow you to treat the Sprite() as a bitmap.Just trying to bridge the gap between vector art and bitmap.

When i apply mc.rotationY=45, It automatically converth the vector into Bitmap.i tryed mc.cacheAsBitmap=false;But still it converted to Bitmap.I need the rotationY as well as the card remain Vector.
View 5 RepliesI am attempting to adapt a face detection application for a project I am working on. It works great, and displays a sprite of a vector square where it detects a face. The problem I am having is that I would like to place a bitmap image (from a source file) instead of a vector square. Here is the snippet containing the drawing of the vector:
Actionscript Code:
/*** Creates a rectangle*/
private function _createRect() : Sprite {
var rectContainer : Sprite = new Sprite();
rectContainer.graphics.lineStyle( 20 , __rectColor , 1 );
rectContainer.graphics.beginFill(0x000000,0);
rectContainer.graphics.drawRect(0, 0, 100, 100);
return rectContainer;
}
I'm pretty sure that this is the only part that needs altering in order to swap the square with a bitmap though.
I have one class called Person that extends a Sprite. First i have a bitmap that i add to the sprite class: This bitmap is a transparent PNG. addChild(_imageBitmap); then i did some drawing in Flash that has the shape of this person and extended this to the SimpleButton. This way, only the edge or the inner shape is clickable. then i add this shape to this Person class too.

I am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.
Every Vector I've ever tested all extend Vector.<*>.
Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>
[code]...
But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.
<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>
[code]....
Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.
[Code]....
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
If I have a BitmapData that's already been drawn onto a Sprite. Is there a way to redraw the BitmapData onto a Sprites Graphics object without having to invoke beginBitmapFill and passing in the same BitmapData?
View 1 RepliesI'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap.

In pure AS3, I have a pixelbender and a large bitmap. The pixelbender is configurable with a distance parameter to affect only a small area of the bitmap.

Is there a way to write a bitmap font right into the bitmap being desplayed? Mabey better worded: myBitmap.draw(image, t) draws a picture is there a way to draw text? I'm stuck even if its just a work around in some way I would like to know... (the current work around i have in my head is writing it in a movieclip turning that into bitmap data and drawing it... esentially creating a prototype answering my question... but a built in way would be easier probably).
View 2 RepliesI have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?
In AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.

Iīd like to take the red pixels from first bitmap (and its positions), and make another bitmap.
I haven't worked very much with bitmap manipulation and I need to create an app that can find a bitmap (or a pattern of pixels really) in another bitmap.Are there other methods of doing it besides iterating through the pixels and using getPixel()?I'm of course looking for the most effective solution.

View 21 RepliesThe great thing about vectors is the data typing / autoComplete.. The thing about them that I hate is the numeric index and the resource intensive retrieval methods you need to pull an element.
so with objects:
myObject["myObjectKey"]
is great, fast, etc. BUT there's no data typing myVector[0].myProperty is fantastic for auto complete, but there's no quick index, instead a bunch of for loop logic that can get really messy in more complicated data models where there are a lot of relationships. Does anybody know of an elegant hybrid solution aside from things like
var myProperty:MyFavoriteDataModel = myObject["myProperty"] as MyFavoriteDataModel;
