I need to load a very big image on AS3 (currently sized at 8192x8192). I am aware that it does not fit any of the limits imposed by Flash regarding drawing to screen or creating a BitmapData of that size. I just want to load the image so I can copyPixels() some parts of it here and there.The thing is, I'm loading the .jpg file of that size with no problems. The size is recognized correctly from my Loader object. I load it like this:[code]But I am greeted with the #2015 "Invalid BitmapData" error usually reserved for BitmapDatas that are too big. The error also happens if I try to do a copyPixels(), which is what I need to do.Is there any workaround I can use so I can get data from an image this big on AS3?
I'm loading a batch of 50 jpgs and once loaded, on enter frame, I'd like to change their alpha individually and apply BlendMode.ADD to all of them (also individually).
I can do this easy using normal Sprite objects, but this is not efficient enough (processor wise). I've played a bit with BitmapData.draw(source, null, null, BlendMode.Add) and that's still not efficient enough.
So I was wondering if I could achieve similar effect using copyPixels (which I know should be more efficient). Still, I'm a bit clueless on how could I apply BlendMode and alpha on a bitmapData object (I mean, I know I can't, but I was wondering if I could make this work using Matrix and filter manipulations).
What do you think about mixing this two up? Would it lead to better performance for the scenario described below?However, method done below still contains jerking/stuttering in animationWhat my app does is to create a random mix of smiley and draw it into the canvas, and update the movement of the smiley (x,y)I have a source bitmapdata containing different smileys each of the same size.Example:The app creates a random mixture of smileys inrandom length;Example:tc...I have 2 vector that acts as pool. 1 vector is to store bitmapdata1 vector to store SmileyObject (SmileyObject has 3 properties, positionX, positionY,bitmapData)If the pools is empty, I create a new bitmapdata and SmileyObjectThe bitmapdata copypixels random smileys from the source bitmapdata.This is then placed into SmileyObject.I have a loop that goes through each smiley objectand copypixel each bitmapdata into the canvas along with the x,y position.However, even with copypixel and pooling bitmapdata + smiley object,I can still view the stutter / jerk / stuttering / jerking in the smiley animation.
I'm trying to know if you can copy the pixels of many objects in one BitmapData without a huge slowdown. The slow down is made by calling the method multiple times, thus making a lot of variable declaration and disposal for the garbage collector. If someone know how to either immitate the copyPixel method or have any other way of solving this problem,
I have the code to copy parts of a huge loaded BitmapData to a target BitmapData that is just the size that I can display. I think I have set the scroll bars of an enclosing Canvas to show the size of the larger image and allow the user to scroll. Now I need to put the selected pixels on the screen. When I try to add a Bitmap component as a child of the Canvas, it get an error because Bitmap is not a UIComponent. What's the best way to put the target BitmapData into an Image component?
When I publish the file, I'm getting the following error message in the Output panel:
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 7: The class or interface 'BitmapData.loadBitmap' could not be loaded. var plaid:BitmapData.loadBitmap("plaid");
I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:
ArgumentError: Error #2015: Invalid BitmapData. at flash.display::BitmapData() at Reflect() at Site_fla::GalleryPage_29/loadThumbs() at Site_fla::GalleryPage_29/sortXML()
[Code]...
btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
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.
I did a function for blit scrolling successfully using Draw(), but then I heard that copyPixels is faster. Unfortunately, I'm not having the same success with that as I had with draw();
Specifically, no matter what I try to use for the source image, it keeps saying that it can't be coerced into a bitmapData object:
Code:
TypeError: Error #1034: Type Coercion failed: cannot convert SourceBitmap_bm$ to flash.display.BitmapData.
I tried referencing the bitmap in my Library (That's how I'd prefer to do it, copy from an item already sitting in my library) that has base class "flash.display.BitmapData", yet I get the error. I tried putting the bitmap into a movieclip and copying from that, same error. I tried copying from an offscreen instance of the mc (which worked fine with draw()), same error.
It's a mess by now because i've tried so many things, but this is my code:
[Code]...
I see are for copying pixels after loading in an external file. Does anyone know of an example that works with items already in library?
how to use the bitmapData collision method. Now I'm trying to figure out if there is a way to see at what angle or coordinate of the bitmapData the collision happens? I need it in order to figure the accurate bounce angle after the collision occurs.
How would I go about using CopyPixels to build an isometric map? CopyPixels takes a specific rectangle and copies that onto a bitmap.. But how would one use that to build a seamless isometric map?Building a square top-down tiled map would be very simple as copypixels pastes each tile next to one another.. But for Isometric Maps, this would be different as some parts of the CopyPixels rectangle is over lapped into other tiles.. and this would 'erase' the bitmap of the other tiles currently on the bitmap..[URL]Fig2, is what happens when you try to do a copyPixel over an existing bitmap, assuming the white is transparent space.
I'm currently working on a flash game and I need to know how to addChild a BitmapData or draw a BitmapData to screen. If I can't than how can I give a DisplayObject my BitmapData?
Traditionally, when blitting in old 2d games, flips and 90 degree rotations could be achieved with almost no performance hit. The reason for this is that the effect an be achieved by simply changing the order that pixels are copied.
I'm using copyPixels in Flash to get maximum performance. Is there any way to do a flip or 90 degree rotation using copyPixels? (Without pre-calculating and storing the flip/rotate). I couldn't find a way to do it, but it seems like it should be possible, because it is a very common technique in 2d games (well, not so much now that modern 2d games use 3d hardware acceleration... but Flash doesn't let us do that, so we need to use the traditional 2d techniques)
I am making a custom renderer using the copyPixels function for my Haxe/Flash game. So I have this kind of code :
buffer.bitmapData.copyPixels(m_CurrentSkin, RECT3, POINT, null, null,true);
where :
-buffer is the bitmap where all my scene's objects are drawn
-m_CurrentSkinis the BitmapData that contains the current frame of the object to be drawn
Every time m_CurrentSkin contains a BitmapData that have never been drawn (the first time that an animation frame is drawn for example),I have a memory leak that is not garbage. However if m_CurrentSkin contains a BitmapData that have already been drawn (when the animation is played a second time for example), there isn't any memory leak.If I comment this line there is no leak so the problem comes from there.It seems that a copy of the BitmapData is cached in memory but I have checked in my code and there is no cacheAsBitmap explicitely set to true.
I am playing around with an old Zelda: Link's Awakening tile set, and was trying to make an application that will display the current selected tile.
I am well versed in as2 but have never had need for the bitmap classes until now. I have found examples of the copyPixel() function that work but could not get it to work in my code.
I have attached the .fla file I saved it as a CS2 (Flash 8) file. (I use CS3 and/or CS4 depending on which computer that I am currently using. This one is in CS3)
I'm working on my second flash game and have been stopped in my tracks trying to cache MovieClip Animations into arrays of BitmapData frames. To capture the frames I have set up a loop which runs through the frames in the MovieClip and use copyPixels to get a snapshot of the graphic.This works fine if the MovieClip to cache does not contain any child MovieClips, but if it does, these MovieClips are frozen on their first frames. I've been looking at MovieClip.getChildAt(index) in attempt to navigate their time lines but because that returns a DisplayObject it seems impossible.
So, my question is: Is it possible it to use copyPixes on a MovieClip and also step through child time lines, or should I be using sprite sheets?
I'm not much of a scripter. I get by editing scripts similar to my needs. I learned a few things about blitting and I'm trying to get a rectangle area of a MovieClip to blit to a location on the stage. But I run into the error "Invalid BitmapData" which makes sense because I'm referencing a MovieClip and not an image. Is there a different AS3 command other then copyPixels that would work for a MC?
I know VCam would seem an obvious solution, however VCam scales to fill the entire stage. I only want to fill a small rectangle on the stage. I've already attempted to edit VCam with no success. Its probably not the same principle, but would it be possible to blit the matrix VCam uses?
I've made a mobile version of my software, with low-res images and such, and I can now fully buffer all my content (including a 360 frame animation which is buffered to memory). Problem is, that everytime I update the view, more memory is used.When I write image = new BitmapData();, does it store the previously created BitmapData's in memory? Do I have to flush the memory somehow before I draw my second picture in BitmapData?Example:
ActionScript Code: // In this example I draw using the same bitmapData several times, also //overwriting the first image. Do I have to somehow delete the data first, to
Is it possible to use copyPixels to capture part of the stage directly into a bitmapData object?
Just wondering because in my situation using captureBitmapData.draw(stage, matrix); is causing performance problems, even without the matrix. I read that copyPixels is fast so I was wondering if there's a trick to use that directly on the stage without the draw part.
What I'm essentially doing is screen capturing a part of the stage and putting it in a a window, using a loop to update it over time since it contains animation. Works great in one of my FLAs, but chugs in the other so looking to optimize the code to a bare minimum.
I have a BitmapData object with transparency (the sourceBitmapData parameter). Every time I use copyPixels() to copy it onto another BitmapData object the transparent pixels replace whatever is beneath them. I would like the copyPixels() function to simply ignore these fully transparent pixels (0x00) and NOT copy themBTW, I've tried setting the alphaMerge to true but that doesn't solve the issue - the whole source object just goes black and ignores ALL transparency.EDIT:
Here are the code snippets; var b:UIComponent = new UIComponent(); b.graphics.beginFill(color, opacity);
I believe this is esentially a math problem that may be easy for most of the programmers out there, but I am stuck. I have a fixed rectangle width = 50 height = 50 centered in the middle of the stage. I am using this rectangle to copyPixels of a bitmap that is also centered on the stage. The bitmap is draggable. I can define the initial x,y of the rectangle used for copyPixels with
I am trying to copy pixels from a user scaled bitmap into a 50x50 target area. I am not seeing the new bitmap does not reflect the scaling of the initial bitmap.
function onSliderChange(e:SliderEvent):void { scaleClip(slider.value, dynamicX, dynamicY); dynamicX = holder_mc.x;
I am working on my own Molehill 2D painting classes. I took a look at Ely Greenfield's M2D stuff but I found it a tad overkill for what I am looking for. So I want to do my own. I have been working off of Polygonal's example. You can check out my code here - http:[url]..........Assume I want to paint one entity that is a rectangular bitmap image using two triangles (essentially a quad). Basically I am having a hard time understanding how to translate this:
Code: bitmapData.copyPixels( sourceBitmapData, sourceRectangle, destinationPt.. ); to this (assuming I am using a x, y, u, v vector pairing):[code]...
Specifically if the source rectangle doesn't contain the same values of the sourceBitmapData.rect. What if I want to paint only a portion of a bitmap onto a quad? Or stretch a portion of the image across a quad.
I'm freaking a bit here. I've committed to building this branded, simple quiz for a client, and I've got the basic functionality running now in an un-designed shell UI. The app is just a landing state, a string of 15 questions built dynamically using a single state, and a result state. Minimal Actionscript controls these rather sparse three layouts, and my 'release' exported .swf file is 308 KBytes. That's a bigger .swf than this giant, giant scrapbook application I was just working on strictly in Actionscript. And I haven't even added the design assets (including animations) to the project yet! I'd hate to see what size this file will be once the graphics assets are added.
Is this simply a drawback of using Flex? Is there some way to slim down the library of classes that are exported into the .swf or something? The amount of code I've written in this thing is ridiculously small, so I'm now wondering if simply using the Flex framework adds this much dead weight to the .swf file?
I've started learning Flash two weeks ago and I have the challenge of creating an interactive political map with about 4000 cities. Some cities will have more than 600 lines defining their limits which will make this project very demanding on processing.People will be able to zoom in/out, select cities and see information about them.As a starting point, I've begun working with 500 cities. I've imported a vectorial drawing of these cities and converted each one of them to symbols using flash javascript, resulting of course in 500 symbols. I don't know if it was a good way of starting this project but worked for me. Then my problems begun.
First I tried to use the mouse roll over and roll out events to change the (fill) color of cities but the city limits (stroke) changed also.Second I want to add some properties to the cities such as city code, name, etc. but I wasn't able to do that using class inheritance. Would I have to create a different City class for every symbol I would like to extend? This approach looks like a lot of headache and redundant work.
I would like to show the top-left corner in my browser and allow user to use automatic browser scrollbars to navigate it.When I publish my swf file, this is well done in Safari, but not in Firefox.Which are the exact publish settings to make it ? I've tried several settings options, but I can't get what I want on Firefox.
