When I created a Bitmap object from drawling the pixels of an image and then scale that Bitmap too large (or even too small) the image disappears or in some cases distorts in what appears to be random pixels barfed all over my screen.
In order to show you this I have made an example: [URL]
(click the plus button any more than 8 times and poof! the bitmap disappears)

What I am doing now is loading a .png image with a Loader object. After loading the file I cast the loaderInfo's content to a bitmap and set the smoothing value to true. This works without a problem until I reach a ScaleX and ScaleY value less than 0.5.
For example, if I have a 1000x1000 object, scaling it down to 200x200 causes the bitmap smoothing to no longer work.[code]...
getting a bitmap to apply smoothing properly after being scaled very small.What I am doing now is loading a .png image with a Loader object. After loading the file I cast the loaderInfo's content to a bitmap and set the smoothing value to true. This works without a problem until I reach a ScaleX and ScaleY value less than 0.5.
For example, if I have a 1000x1000 object, scaling it down to 200x200 causes the bitmap smoothing to no longer work.I can reproduce the problem using all of the following Sizing methods:
Change the scaleX and scaleY properties on the bitmap. Directly change the height and width properties of the bitmap. Add the bitmap as a child of another sprite and change the scaleX and scaleY properties of the sprite. Add the bitmap as a child of another sprite and change the height and width properties of the sprite. Creating a new BitmapData object with a matrix scale and then drawing the original BitmapData onto it.I've also tried some other workarounds that I found when searching, such as:setting the scaleX of the image to 1.001 or 0.999 forcing the height and width of the Bitmap object to be even numbers.
Below is some sample code for reproducing the problem. (I am running this locally so I have a copy of testimage.png in my bin-debug folder)
public class MainObj
{
public var comp:UIComponent;
public function MainObj()

I have an image, that will be dynamically loaded. I have some graphics drawing tools with which a user can draw something, which is saved on a shape object. Now what i want to make the uploaded pic & drawing pic into one pic. Actually it will be better if i can draw on the uploaded pic.
View 1 RepliesUse the flash CS4 tool's on a bitmap image after tracing the bitmap image and applying my settings?
View 10 RepliesZoom in on the snowboard and drag it around, it appears the low-res image is updated with hi-res patches on the fly. Is this a function tied to the bitmap object... or did they write some fancy code to pull in and assemble a sliced up image, and then replace the low-res slices on the fly. [URL].
View 1 RepliesThe solution should be straight forward but I cannot find it, my problem it's that I'm reading a xml, and one of the properties inside the xml it's a Bitmap path(string), when I`m reading this xml I would like to convert this string to a Bitmap Obj so I can use through my MXMLs.
View 4 RepliesI 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),
how I could setup an Image so when it loads, and I change its Z value, it doesnt keep shifting in reference to the upper left. Right now, when I change the Z value of a Sprite containing the Image, it appears to move x, y (even though I know they are not changing). I thought that by putting it inside of a sprite, and then moving the image to so that its center was at 0,0 inside the sprite, that when I changed the z value of the sprite and not of the bitmap itself, it would fix my problem, but its not.
bmp = new Sprite();
var bmp1:Bitmap;
loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, fileLoaded);

I'm implementing a frame class that builds a graphical frame around children using 9 bitmaps (4 corners and 5 middle pieces).The frame extends sprite, and the 9 frame bitmaps are attached as children. They are repositioned as necessary to encompass any other children on the sprite.
This works fine, normally, but as soon as I rotate or scale the frame, the children split apart, showing what appears to be a one pixel or partial pixel gap between the pieces.
I've tried setting pixelSnapping = PixelSnapping.NEVER on the 9 bitmaps. I've tried turning smoothing=true. The children bitmaps are always positioned at integer x, y's, never fractional. I've tried setting the scale of the children bitmap to 1.01 and PixelSnapping to AUTO. None of it works.
I would like to make a very simple (well, looks simple anyway) image gallery, like Ilyas da Pom's at [URL]..
I want the image part to scale to fit each image dynamically. I'm a brand-spanking new Flash novice, and any guidance would help really; this is just a tiny little personal project, not to be used anywhere commercially.
does cached a bitmatp improve speed of vector object or bitmap object?
View 1 RepliesI'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:
public var contrailBase:BitmapData;
public var contrail:Bitmap;
private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?
How to scale an object using actionscript?as you know scaling using motion tween is not as smooth as using as.
View 1 RepliesWhat would be the best and fastest way to scale/resize an image which is injected into PHP file which is called via AJAX with use of jQuery?
So I am trying to assure the image does not bypass the width of 600px and height of 410px but I do not wish for the image to be maxing out this dimensions and look weird, it has to be displayed as it would be, but just in smaller scale.
Also if there is a way I can do this with a already existing Flash script that would be great, but I do not recall of any good ones which are as simple as one used by Google on there Picasaweb service.
Most often, questions are asked about how to scale a DisplayObject, and the answer is usually to use a Matrix.
My question is, how to you GET the scale of a Matrix (scaleX and scaleY)?
There's a Matrix.scale method to set the scaleX and scaleY, but it doesn't return a value, and no other properties exist to read it back.
The reason I ask, I'm using object burried deep down into a Display list, and each may be transformed. So I use the child object's sprite.transform.concatenatedMatrix getter, but am stuck at this point on how to read the scale from it.
I know it's possible to scale and rotate an object by using some actionscript. Is it also possible to distort an image?
For example; keep the topleft corner and the bottomleft corner of an object at the same position and put the topright and bottomright corner of the same object 25 pixels down.
I have built a very simple Flash gallery in CS4 using AS2. It calls the images from an XML file and works great. The problem is that the captions underneath the images are in a fixed width text box. They look fine underneath horizontal images, but I want to have the text shift in when a vertical image is loaded, and is narrower.
View 3 RepliesI have made an application where you can design your own greeting cards. I use matrices to scale and rotate images, and I always need to know what scale the image has.
It works when the image isn't rotated, by taking the value from matrix.a or .d which are the scaleX and scaleY values. But when I rotate the image, using the matrix.rotate() function, the a and d values no longer corresponds to the scale of the image.
How can I get/calculate the scale value of an object that is rotated? And I don't want to scale the image by using the scaleX and scaleY methods.
Why is it that when you animate a photograph (especially animating scaleX or scaleY), it looks so crappy? I've tried caching as a bitmap, turning off compression, etc, but not What's the story here?
View 5 RepliesI tried many Flash .swf before and they all can be scaled freely -- by using a width and height in the HTML, and sometimes in the URL params or flashvars. But is it true that all Flash object can be scaled? For example, can some Flash objects using absolute coordinates to plot graph so that every 10 pixels it marks 1, 2, 3, 4, 5, and no matter what is done at the HTML or any where else, it just won't scale and the browser can't do anything about it either? Is there a way to scale it to half the size for that graph? (that is, 1, 2, 3, 4, 5 is separated by 5 pixels instead of 10 pixels)
View 1 RepliesLet's say I have a movieclip, which contains a simple circle draw on it. What I need is to scale the movie clip along a random line (not vertical or horizontal only). The picture attached probably illustrates what I mean. The only idea I can have is to combine usual scaling and rotating.

Like in this example but with actionscript instead of motion tweening.
I have a little problem, I'm writing an app, where flash attaches a movie with attachMovie and in addition, I add an object with its _x,_y,_xscale and _yscale. Now what I need to do, is not to attach a movie, but to load it with MCL. The problem is,that I don't know how to attach an object with its _xs and _ys to a movieclip loaded. Furthermore, when loaded,it doesn't appear in a library, so I could attach it. Setting parameters manually would take tons of time, so I'm looking for most "economical" solution.

How can I scale an object from center after it is dragged by the user?
Currently I have this:
function onSliderChange(e:SliderEvent):void
{
scaleClip(slider.value);
}

With this code the movieclip jumps back to the center of the stage each time I call the scaleClip() (move the slider). I would like the object to scale from it's own center regardless of where it is on the stage.

I am wondering how would I scale an image on browser resize with minimum and maximum width and height parameters?
I know how to use the Event.RESIZE function to make my image proportional with the browser using stage.stageWidth/Height, but I am trying to figure out a way to have a movieclip or image scale up or down to a certain dimension such as on browser resize the image max would be 640x480 and the minimum being 320x240.
I'm trying to make a zoom in and out effect, on images in a movieclip, using the mouse wheel. But, there is another mouse event that scrolls through the frames of the movie clip. I need it to stay zoomed in, and out respectively, when you scroll to the next frame.
