View 1 RepliesIn a project we use large flash FLA file with lots of graphic assets, but the actual data that is changed is just in a few symbols. Sometimes it is not very efficient to transfer the whole FLA file that comes up to 20MB now.
I was thinking about using Shared Libraries, but it seems that, even if you import external library, it still copies the whole assets into the destination file, but does not link it from external file. Consequently, size of the FLA file still remains the same.
Is there any way to split FLA files into few separate in order to minimise size of the most frequently updated file and keep all unchanged data in another file?
I'm trying to minimize the size of my SWF, but I can't find the tools that I need. HI need a tool that will take my SWF (or .as files would work as well, I suppose) and deconstruct it, analyzing how many bytes each class contributed to the final SWF file size. I would like this analysis to occur for both 'built-in' Flash classes ('flash.util.*', etc), as well as my own hand-written classes. (Other languages, such as C, Java, OpenLaszlo, etc, provide this functionality in a straightforward manner, but I'm stumped with AS3). (Note that I'm compiling with CS3, but Flex SDK solutions are also welcome)
Armed with this information, I'll be able to identify which classes are contributing the most to file size, and optimize them as necessary. For example, Flash's Button class is a bit bloated for simple applications - this tool would help me realize the inordinate number of bytes the Button class is contributing and re-write a simpler Button class for my needs (which inadvertently, I've already done ).
What does this mean? "Minimize the Flash movie size by limiting the glyphs embedded in the movie" in sIFR3 to improve rendering speed What is the meaning of "limiting the glyphs embedded in the movie"?
View 1 RepliesI have a performance question about pixel bender. I want to enlarge many BitmapData (double their size into new BitmapData). I was doing this with as3, but wanted to use pixel bender to get better performance. On my machine, I get better performance out of pixel bender demonstrations then as3.
To my surprise (or bad coding / understanding), I am getting much worse performance out of pixel bender -- 2 seconds vs 1/2 second! I expected to get at least the same performance as as3.
I got the straightforward pixel bender code here (and it is included below for easy reference).
package
{
import flash.display.BitmapData;
import flash.display.Shader;

I have several SWFs pulled in at runtime from different domains (we're using a CDN). There are some shared fonts within the SWFs. I'm trying to minimize file sizes as much as possible, so that means either not embedding the fonts in any of those SWFs and setting all their TextFormats at runtime. That's very impractical, and it would be easy to miss some of them.
The other, better option is to use runtime shared libraries to pull in the fonts, but that requires either an absolute URL (goes against the concept of using a CDN), or a relative URL (defeats the purpose of using RSLs in the first place since those resources would be downloaded several times anyway). Ideally i'd like to be able to tell each SWF at runtime where to pull in the fonts, and give them all the same, dynamic URL. I can't find anyone who's encountered a similar situation, so i'm not sure if this can or can't be done, but most AS3 problems i find are solved here, so i'm hoping someone knows a good solution for this.
I am using the floodfill method to colour-in sections of a bitmap image. That part is easy enough but the issue comes in with the way I am adding an effect to the colour fill routine.
To add the effect, first a copy of the bitmap data is created and floodfill is used on that instead of the original bitmap. Then the bitmapdata.compare method is used to set the alpha value of everything apart from the filled-in section to 0 and the result is saved in another bitmapdata. After that, a 1 px radius circle sprite is added to the stage and is being tweened to the image dimensions and its mask is set to the sprite which contains the result of the compare operation.
This works perfectly except for the fact that the fill sprite has to be tweened to the complete image dimensions irrespective of how small the area is being coloured-in since I am not able to find a way to get the dimensions of the fill area. I am doing an bitmap image update at the end of the tween and I have to disable user interaction till the tween is complete to avoid the errors which come in if another fill-in operation is started before the base image has been updated. If I could somehow get the dimensions of the fill area then the time during which I have to disable the user interaction will go down considerably.
Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!)
SWFUpload - latest release 03/2010, documentation
fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?
I have developed a video player in adobe flash cs4 and used all vector arts but when I open this fla file in Adobe Flash CS5 and published it, the swf file size more then fla file.
Adobe Flash CS4 -
Index.fla file size: 523 KB
Index.swf file size: 55 KB

I would like to run a .swf file into an existing flash file, but the dimension size of the .swf file is too big. I am a beginner to flash and not sure of the steps to execute this. Would anyone be willing to walk me through the steps to import the code?
View 1 RepliesOne of the most annoying things when working with Flash/Flex projects is that it takes soo long to build the project. In a Flash game I am doing, it takes more than one minute to build it.

The bitmap resource, It's usually make the bitmap generate the SWF file ,and use Loader class to load into the application. I search some answers from google, find two ways to generate SWF File, one. use mxmlc tool. and another, use jsfl. I know we can embed the bitmap or swf file into As code. and use mxmlc command like this: the as file is Vip.as , and the code :
package
{
public class Vip
{
[Code]....
I don't know how to use mxmlc generate swf file . And no error when debug the code.
Another way is that use JSFL to generate SWF in flash cs5, But I don't know how to use this. Ah, very pain.
I make use of a bitmap picture, size 1920 x 1080, as my stage background. That image never moves ... well I may add mask to it later on, I'm not sure yet.
Nonetheless, since it is static, is it a good idea to cache it as bitmap? is it only for vector artworks?
I want to convert bitmap data to an image file like jpg or png file in AS3.
View 1 RepliesIn Flash, the BitmapData object can be used to store bitmaps in RAM, you can later draw them to a MovieClip using the beginBitmapFill() method.
How do you load an external bitmap file (.jpg) into a BitmapData object?
When I preview my flash file it says that the filesize is 29kb. However when I look at the properties of the outputted swf it's coming in a t 36kb. Which is the correct size? Also what extra information is being added to push it up by 7kb?

View 2 RepliesHas any one experienced a crash when using "test movie" in Flash CS4 on Windows 7?For me, it started when I began working on an Actionscript 2.0 project. It happens every time I test a movie, then minimize the window.I have tried re-installing Flash, but the problem still remains. The weird thing is, it waits until I minimize the window. No other time.
Test movie --> Close it --> Minimize Flash --> Wait a second or two --> Crash

View 1 RepliesI made a preloader for my single scene movie and although the preloader is about 16k, when placed into frame 1 of the movie and tested, the frame is shown to have about 256k, which is larger than the movie it's loading. I've gone through all the files and made sure that export in frame 1 is not checked and made sure the publish settings also are set to export in frame 1.
View 5 RepliesI've written a class that iterates through all the frames of a movie clip and draws each one to a different bitmap. When I'm done, I should be able to iterate through the bitmaps and play them like a flipbook animation.If I draw all the clips to the same size bitmapdata, then everything looks great. But this is wasteful because now a lot of the bitmapdata's are bigger than they need to be (takes up more memory), and also causes problems because the hit tests don't look right.
So next I try to crop all the bitmapdata to be the smallest possible sizes. However, when I do this, there are subtle differences in the way the images look - the edges might look slightly darker in one frame than in another. When I line up all the images and play them back to back, it no longer looks the same way it originally did.I have no idea why the images look different, and have no idea how to work around this problem, I have tried many different approaches. I have tried using BitmapData.draw(), BitmapData:copyPixels(), and manually using BitmapData:SetPixel(), and all end up with the same result
Usually maximize, and minimize works while i am opening video player in windows, but when i upload it on website, i cant use maximizie and minimize option. Any working code for websites.
here is my html code: <

If I publish the same fla in CS5 and then in CS5.5, CS5.5 is about 4k heavier.
View 0 RepliesI am just curious to know if the amount of classes you import into your flash class, affect the size of the class, the size swf file, or the amount of memory allocated. If so, does this affect take place before or after you initiate the class.
View 2 RepliesI am a beginner in flash action scripting program. In our project we need to modify some flash files. Client has provided us .swf files. I have decompiled .swf files using Sothink SWF Decompiler. When I copied the actionscript file into a new flash file the new file size is decreasing when compared with the original flash file.
View 1 Replieswe are doing a seamless interactive video-game-video project, but are having optimization problems. Because the client wants a full-screen option for both the video and game segments, our file size is too big. Any advice on how to minimize load time yet retain a relatively high-quality image standard? The h.264 image quality, but there are licensing issues, and we need the transparent alpha channel for the video segments.
