Does anyone know of a way to crop out whitespace/transparent pixels in a BitmapData object? I've got this movieclip I'm rendering that has a huge amount of whitespace all around it. I'd like to crop all of that out before I convert it to a JPEG (with corelib). Is there a way to do this? I can't seem to find a way to figure out where the first opaque pixel starts on each axis to determine the extents.
View 6 RepliesAfter seeing the I've been told that movieclips aren't suited for games, what do you use? thread, I thought I would try to incorporate the approach into a game I'm currently programming to make it a little less processor intensive.
I have a giant movieclip of a football field, of which only 5-10% is shown at any given time. I'm guessing that flash still has to make calculations for the other 90-95% of the field every frame, even though it's of no use. From what I understand (not much), copyPixels seems like the perfect candidate for such a situation.
It seems simple, but I'm having trouble actually implementing it, and I'm not sure which actions are needed and what might be introducing unnecessary work. I have a movieclip (mc_field, exported for as), but if it would save the processor some effort,I could easily save this as a bitmap and export that for actionscript. The width and height of the final product (bitmap/BitmapData) will be Stage.width, Stage. height,respectively,and I can handle making the calculations of the x,y coordinates of the rectangle cropping (which part of the source bitmap I want to crop).I'm sure it's only 3 lines of code, and I know that there are a few examples online, but for some reason.
Say, for frame one, I want to take the field (either mc_field or bm_field) and copy 500px x 300px, starting at 140,230 from the source bitmap to mc_container.Then, for frame two, I want to copy 500px x 300px starting at 240,540 from the source bitmap to mc_container.
I wrote a collision detection class that works off using BitmapData.hitTest. Basically, every update, the .draw method is called and then two BitmapData's are hitTest'ed against each other to see if there is a collision.It works pretty well, however if I start rotating the source MovieClip I use for the BitmapData, the transformations don't get registered in the draw method. So what I did was pass through a Matrix in the draw method. That works. But here's the actual issue. If I output the BitmapData to a Bitmap on the stage, I see that Bitmap is, in fact, rotating, but now it's exceeding the bounds (width and height) of the BitmapData. Which is cropping / clipping the image of the source MovieClip.
UPDATE: Basically, when the Bitmap clone of the MovieClip rotates outside the positive co-ordinate space, it doesn't get drawn. It rotates outside the bounds of the BitmapData set width and height. I can multiply the bounds by 2, and then center the bitmap inside the set bounds, but then the origin point is never fixed and the object is always being moved around. Works pretty well, but makes aligning the object to any specific point impossible.Here's my isolated test code. It requires you to have a MovieClip on the stage named "iTest". I used a fairly vertical arrow shape (higher than it is wide) so I could keep track of rotations visually accentuate the clipping problem:
var rotateTimer:Timer = new Timer(10);
function rotateObject_init():void
{

I have few ActionScript skills. But I have built a multimedia career by stealing chunks of AS2 code and reworking them to suit my purpose. I have searched long and hard here for a solution to my current problem. I have found code here that seems to address it, but I cannot make it work. I simply have some textAreas that I wish to validate. The user may input text that could include extra spaces, returns, and odd capitalization. It would be easiest for me to simply strip out the capitals, spaces and returns. I found some simple code that changed the caps to lowercase:[code]
View 5 RepliesI've managed to get myself stuck in a situation where a database full of images ( transparent images of various products ) needs to be placed on the stage, all of which need to be aligned the same by the products height. My problem is that the png's of products are 'floating' and I have no control of where about's in the png it will sit ( could be tight at the top and loads of room at the bottom, vice versa)
Does anyone know an existing way to find out the png's 'true' height ( width is an extra ). I've thought about looping through the bitmap data and checking but wondered if anyone has invented this wheel already?
I'm trying to serach for the following string "Type/Pages" in long external files and am using the follwoing code which works: indexOf("Type/Pages");

I m building a site whit transparency so my background HTML can bee viewed, at some point I load a movie on level1, it's supposed to bee smaller than the Level0 movie but instead I end up getting flaps on the level0 movie because the original content of the level1 movie sticks out, I can't put a mask for it will occlude the HTML background, and it doesnt matter if I keep shortening the loaded movie it still shows up like it has a mind of its own...
View 3 RepliesI have a website I'm making. The contents of it is set via xml documents.Now because in the xml for the sake of keeping it clean I make sure when setting all text to any TextField I set it with condenseWhite set to true:[code]Now this condense white creates a few weird bugs when using htmlText... things like img tags acting really weird and the sort.But that isn't my concern right this second. What I want to do though is allow the user to choose the ability to preserve whitespace in some manner for instance here is the main xml document loaded and used to load all subsequent docs:[code]
I've tried stick in there and that fails. I've tried the <pre> tag from html, failed, which I assumed it would. %20 doesn't either.I also thought of sticking a "preserve" attribute on it and checking that before setting text (as you can see in the xml code)but in some scenarios in my application it creates very convoluted code just to update dynamic textFields (I have textfields that swap out a lot, like in the photogallery as can be seen here: URL...Or maybe knows a site that has a well documented explanation of the html abilities of the TextField.I've been reading around on the internet and playing in flash for a while now testing different things and still no result.
I have a variable that contains the text from an input box.
let's call it "name"
People may enter the persons first and last name into this box. If they do .. I want to be able to capture just the first name from that string. So somehow capture everything before the first whitespace.
I recently made a flash document with animations and some AS at 1600 pixels wide. It turns out that my web developer is having trouble using the file and would like it cut down to 1200 pixels wide. I can make the document 1200 wide, but then everything is off-center. Is there any way that I can crop it to 1200 my taking 200 pixels off of each side instead of just 400 off of one side? If not is there an easier way to just select every layer and tween at one and move them over

When I try to load text from XML into a text field any leading line breaks or spaces are ignored. For example:

SO I am working on animating a 20/fps sprite (an SCV from Starcraft 2). The animation is 1 second long, and thus 20 frames. I have made a sprite sheet in photoshop, and have each frame as a separate layer. I import the PSD into my library and have it convert the layers to "Flash Frames". I get each frame nicely tucked away as a layer in my library. Problem is, it gives an ugly white border (about 1 to 2 pixles thick) around my sprites, making it look like I did a terrible crop job. However, the crop job is fine (I can change the background in the PSD to black, and the cropped sprite frames look perfect! What have I done wrong or need to do?

View 2 RepliesNot sure if I phrased that correctly. I have about 6 pieces of illustrator outlined text.imported into flash, set as symbols with event listeners and works fine. but i notice I can only click on the outline itself, if i click on the inside of an "o" or "R" it doesnt work.I added white boxes behind each of the symbols and that fixed the problem, but now i want to do a color transform on the symbol (the text only of course), but when I apply the transform, its the background box and the text that have the new color applied, just leaving me a rectangle. I gave the box an alpha of 0, hoping if i didn't affect the alpha in the transform, the pointer would still read the box, but no go, it doesnt even see the box again.

I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

View 2 RepliesWhen using the Loader class to load an external SWF into another timeline and then displaying that SWF using addChild on the loader.content, one discovers to one's consternation that elements positioned off the stage of the external SWF are still displayed.To illustrate this with an example: suppose you have a 500x500 pixel "main" SWF, and it loads an external SWF at runtime and positions it in the center of the stage. And suppose that this external SWF's document properties set the stage width to 200 x 200 pixels. However, when authoring this external SWF, we draw a box that's 300 x 300 pixels, so part of this box is actually off-stage.
When you play the external SWF in the standalone Flash player, it is sized correctly at 200 x 200 pixels, and the rest of this box is cropped off.When you load this external SWF into the "main" SWF and use addChild() to put it on the stage, you will see the full 300 x 300 pixel boNow of course, we can simply solve the issue using a mask, but I'm wondering whether there's a more elegant solution that's built in, either to the MovieClip or the Loader or the LoaderInfo classes. Something that says "respect the document bounds of the original SWF" or "crop to stage dimensions".
Turning of the whitespace around relationals formats the code into:
getDefinitionByName("Helloworld") as Class
