is copyPixels not as speedy as it should be when Tweening large bitmaps ?
copyPixels does a wonderful job on images 500x500 or less, but on larger images, my motion is not as smooth.
all i'm trying to do is slide an image from stage.stageWidth to 0 (right to left).
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 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;
[code]....
I have a 50x50 fixed rectangle in the center of the stage. I am using this rectangle as a "hit area" to copy pixels of a bitmap that is draged by the user to line up an area of the image he/she would like to crop.I have preview of the hit area displayed while the bm is being dragged which works well. However, once the bitmap is scaled using the slider component the preview area no longer reflects what is in the hit area.
Code below:
function mouseDownHandler(e:MouseEvent):void
{
// Contraint #8 - Define drag bounds[code].....
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 using a 3800x3000 bitmap as a background of a game.
Now, I first show the whole bitmap - the landscape -, and than zoom in at the characters. I'm using TweenMax from GreenSock, but even with this advanced tween class my bitmap doesn't move and scale smooth.
I'd like to work with smaller bitmaps too and scale them, but than I'll lose the quality, and I can't blur the bitmap to hide the quality loss, since there's a terrain in the bitmap too, and I don't want to blur that.
Let's say I have some background made up of 4,000 small vector images (doesn't matter what they are, say flowers or stars or something). Once this background is set, these small items won't move or animate. The background will stay the same.What I would do, rather than keep 4,000 sprites on the stage, I would create one single background "Bitmap" which has all the sprites drawn onto it once.Is this still a good idea if that Bitmap is so large it covers the entire stage (which may be quite large for larger monitors if using NO_SCALE and fullscreen or something), or is it better to break that large Bitmap into 4 or more smaller ones placed seamlessly alongside eachother to seem like a large one?

I have a project that is drawing ~10,000 small tiles into one large bitmap container - it's a mosaic... In Flash proper and in FireFox it takes about 20 seconds to complete the drawing. In Chrome it takes about 1:30 and in IE it takes roughly 3:00 - both too slow to be acceptable to the client - who of course reviewed with IE...
I have Flash set to run at 45 fps - and the images are populated by a Timer - at 2 ms intervals... Maybe 2 ms is too fast? But in my testing 1ms was slower as was 3ms... so I kept at 2. And works fine in FF and Flash...

View 4 RepliesRequirement: Create single very large bitmap data which contain some 30 PNG images loaded and for each image it should have some text. Images and text are loaded dynamically (AS2 code. Images are stored in a remote server). The bitmap data display should show 8 images at a time and corresponding text. We can see rest content by scrolling (kinetic scroll is implemented). How can I go for it?Some questions:Is there any limit for size of bitmap data ( As per link there is restriction on the height of the bitmap we can create in AS2 (max value is 2880 which is not enough for some 30 element list If we create individual bitmap data for 30 individual PNG files, we find some jerks in scroll. How can we have smooth scrolling?

View 2 RepliesWhat I want to do is draw the outline of an object using the IDE to create my movieclip symbol...this object will be an enclosed region e.g a cloud. I then want to be able to fill the internal area of the object with a bitmap using actionscript.
I had assumed that I would be able to do this via graphics.beginBitmapFill but there doesn't seem to be a way to specify to draw the outline within the MC or to do a floodfill with a bitmap using a point of origin within an enclosed region.

View 1 RepliesI've just switched over to AS3, and I'm completely stumped with something.
I'm working on a project where I keep adding children to a MC already on the screen. There are two types of these children: Sprites that I use to draw lines using moveTo, lineTo, ect. Then there's sprites that have children inside of THEM that are bitmaps.
For some strange reason, the Sprites with the bitmaps on them always have a higher depth/index (AS3 terminology is still weird for me) than the normal Sprites.
Here's a diagram of my MC/children/children layers:
---------------=> (Sprites that draw lines)
(MC on Stage) =>
---------------=> (Sprites that hold bitmaps) => (Bitmap)
I wanna transform and distort my sprite which has bitmap childs from this ._ |_| To this .._ /__
View 3 RepliesI want to load an external image (dest) and display it on the stage, and i want to load another image (src) which will not be visible. When i hold the left mouse button on the image that appears on the stage, then a function that start copies the src image to the dest will be invoked. Actually i want to reproduce the scratch effect on an image that hides another underneath. here is my code [ the copypixels function is triggered on mouse_move event for debug purposes ]
package
{
import flash.display.Sprite;
import flash.display.BitmapData;
[Code]....
Although the two images are loaded into memory and the first one is shown on the stage, when the mouse_move events triggers the corresponding handlers the copy does not work.
can you create arrays of Bitmap and Sprite Objects? or Custom Objects?
if not, how would you typically create multiple Objects of the same type? just a loop with
var enemy:Sprite = new Sprite();
for(var count:int=0; count<10; count++)
{
enemy = new Sprite();
[Code].....
That way could be fine for many things, but theres other things I want to do.. such as, create an array of wav sounds.... and my program could pick and choose them, so they wouldnt need to load them on demand.. midi files too.
I'm making a game where the player moves around a map, where the player can walk and where they can't is decided by the color of the pixel they are trying to move onto, which I get using the Bitmap.getPixel method.
What I'd like to do though is when the map image is loaded process it into a sprite or something which I can then use the DisplayObject.hitTest methods on. So I have an array of colors whcih the user can walk on, is there way I could go through each pixel and build something that would let me do that?
Is there a way to detect the type of a DisplayObject with a switch case statement?I noticed that you can check if the displayobject compared to the type returns true or false.
Trace(mydisplayObj is Sprite); //return true or false
Trace(mydisplayObj is MovieClip); //return true or false
But isn't there an option to get the type of the displayObject directly?
like,
switch (typeof(mydisplayObj)) {
case Sprite:
break;

I'm trying to export to PNG from the JSFL document.exportPNG function with 'bCurrentPNGSettings' but it fails. Flash keeps complaining that "The bitmap is too large.The largest bitmap that can be created is 8000x800 pixels."The width x height of the document is set to 1920x1080 and I've tried modifying the publish profile appropriately.Still no-dice. If I set 'bCurrentPNGSettings' to false so that the export dialog appears it pops up with the correct width and height; clicking OK exports properly.
View 2 RepliesI'm trying to get a transparent image to fly in from the side. So, I *thought* I was doing the correct thing by moving the "symbol" off of the visible portion of the stage, and creating a motion tween to move it onto the stage. The motion works, but the quality of the image in general (and the text in specific) looks pixelated.Thus, I did a little bit of snooping, and everyone said that you should start with a bitmap. So I saved the image from Photoshop into .bmp format, and was able to set the properties to "allow smoothing" and with lossless compression. So far, so good. Now, as I expected, the transparency is no longer there...
So here's the question: how can I make this image retain its quality, still have transparency, and a motion tween?It seems like this is some set of characteristics that don't play well together, even though I see this type of thing online ALL the time.I tried "Trace Bitmap" to convert to a raster image, and tried to follow some suggestions online, but when I do "Trace Bitmap", it ends up looking like it has a bunch of grayish dots on the image... definitely NOT what I was expecting.
