I've got another simple question. I have a mc who's bitmap that is associated with him I want to change.
[Code]...
When BlankClip is first created, I want to tell it to either have the same image as Block_0 or Block_1. Looking it up online, it seems like I have to use BitmapData somehow, but I'm really unfamiliar with things...I've been working on this same code for about 2 hours...
I 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),
I have a swf I'd like to make a minor change to. Basically I need to change one bitmap, I've tried decompiling it but then it fails to recompile. Is there anyway to hack into a swf file and just change a bitmap?
View 5 RepliesAs of right now, I am trying to create a tiling effect for a game I am creating. I am using a tilesheet and I am loading the tiles to the sprite like so...
this.graphics.beginBitmapFill(tileImage);
this.graphics.drawRect(30, 0,tWidth ,tHeight );
var tileImage is the bitMapData. 30 is the Number of pixels to move retangle. then tWidth and tHeight is how big the rectangle is. which is 30x30 This is what I do to change the bitmap when I role over the tile
this.graphics.clear();
this.graphics.beginBitmapFill(tileImage);
this.graphics.drawRect(60, 0,tWidth ,tHeight );
I clear the sprite canvas. I then rewrite to another position on tileImage. My problem is.... It removes the old tile completely but the new tile positions farther to the right then where the old bitmap appeared. My tile sheet is only 90px wide by 30px height. On top of that, it appears my new tile is drawn behind the old tile. Is there any better way to perfect this. again, all i want is for the bitmap to change colors
Is there a way to dynamically change the path of the Bitmap on the Library? Using actionscript?

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?
So I have a bunch of objects (thumbnails) and I want every photo to be displayed on top of other photos once it's clicked. So what should I put inside the click handler inside the photo object?
View 1 Repliesbasically im trying to set a bitmap to follow an object i have.heres some code...
Code:
override public function paint():void{
super.paint();
if(imageLoaded=false){
trace("loading image...");
[code].....
all the stuff in the loadImage() used to be where loadImage is called and it would run but would draw the image over and over leaving a trail so i moved it so it would only draw once but now it wont even work, tells me "Error #1009: Cannot access a property or method of a null object reference." which reffers to "mBit.x = super.px;".
how to smooth scroll a bitmap object?? When I use the bitmapData.scroll() method it is jerky.
View 3 RepliesI am trying to load an sprite into a bitmap, but cannot get the sprite to fill the bitmap. Here is the results I am getting: [URL]
here is the applicable part of the code I am using that gets these results:
function(){return A.apply(null,[this].concat($A(arguments)))}addChild(container); //add sprite to see true sizebd = new BitmapData(container.width,container.height,false,0xff0000); //colored for effectb = new Bitmap(bd);bd.draw(container);addChild(b); // add bitmap to compare to sprite
I'm using the regular 3D API of flash player 10 and i'm rotating on the Y axis a sprite which contains my bitmap. Although the bitmap.smoothing property is set to true, the bitmap is far from smooth.

Error : flash.display:BitmapData to an unrelated type flash.displayisplayObject. is there a work around that will remedy this?
Is it possible to draw a Bitmap to a Graphics-Object like
this.graphics.beginBitmapFill(bitmapData, matrix, false);
this.graphics.drawRect(0, 0, w, h);
this.graphics.endFill();
with an offset?
A simple moveTo(x, y) call before beginBitmapFill does not work :/ Neither does changing the x and y value of drawRect... (That just seems to have the same effect as an translation with the matrix...) Additionally I don't want do draw that thing in a separate Graphics-Object and add that one into the other...
In 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?
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()

Zoom 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 RepliesI am trying to load images dynamically to my stage. I am reading an xml file and trying to add the images0 to the scene. For some reason the image file seems to be loaded (I have put a trace "Success to check it") but when I try to addChild nothing happens. This is the code of my class followed by the code of my flash file: The main idea here is to load as many thumbnails as the xml file contains so I can play with them making a horizontal scroll.
View 12 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 RepliesHow to do level adjustments (like Photoshop levels) on a bitmapData Object using the paletteMap method. I am fine with syntax and all that, just don't understand how the channel array values are used well enough to come up with them for myself. I have read to use a palette of 0 and 1, but I am not sure what that means. The goal of this is to take a grayscale image and get sharper black and white values for it. Also, I hope to understand how to use this method better in general.
View 1 RepliesI have an MC being duplicated to 2 bitmaps but they are created before the MC performs its internal script. How to change that order? See sample .fla.
View 2 RepliesI'm playing with Local Shared Objects, and I was able to save and load simple data types like strings and integers. Pretty cool.
I want to Save/Load a Bitmap Object but I'm having problems. I think I got a Bitmap Object to save but when I loaded it back in, it was basically a blank bitmap. I located the actual .SOL file on my computer and opened it up. It had some basic Bitmap info like scale, rotation, visible, width, height, etc, but NOT the actual bitmap.
So I realized that I need to be saving/loading a BitmapData object instead of just Bitmap. BitmapData holds the actual bitmap pixels, I think. Anyway I saved out a BitmapData object. When i tried to load it back in, I get a type coercion error: "Type Coercion failed: cannot convert Object@df355b1 to flash.display.BitmapData". I dont get it because this error didnt occur for Strings, ints, or Bitmap Objects. Whats happening?
Also, I looked again at the .SOL file after saving out the BitmapData object, And I dont see any pixel data there. The bitmap I'm saving is 800x800 so the .SOL file should be pretty big but its just a tiny file so I know the pixels havn't been saved properly.
Here is the code I'm using (Simplified - error handling removed, etc)
Code:
// save
var mySo:SharedObject = SharedObject.getLocal("mysharedobjecttest");
mySo.data.testA = 14;
mySo.data.testB = "hello this is a test";

Using Actionscript 3 is there a way to search one bitmap for the coordinates matching pixels of another bitmap?
[URL]
Somehow you would have to loop through the bigger bitmap to find and the the pixel range that matches and return those coordinates. For example the Bitmap with the "E" is 250 pixels over and 14 pixels down in the bigger bitmap.

This code
trace ("--before-- "+sprite.width + "," + sprite.height);
this.sprite.rotation = obj.rotation;
trace ("--after-- "+sprite.width + "," + sprite.height);
[Code].....
Obviously there are 9 instances. So 18 lines output. note that the width and height getting swapped randomly for some only.
I'm looking for a good method to compare a single bitmap data instance against an array of stored bitmap data objects. I need to figure out how I can compare and arrive at the conclusion that the result either means that the images are of the same object/aka similar or if they are two totally different images. I tried checking threshold of the result of the compare() function but my efforts have failed so far.
