I want to getpixel value of a pixel in Stage. Stage is dynamically created and its have movieclips or images, thats are all dynamically created,
But Now I need to get a pixel color value of (150,150) in the stage,
I'm writing an applicaton which acts based on different colour values of pixels in a png image created in Microsoft paint. However, when I load the image into a BitmapData object, and then parse through the pixels reading their values using getPixel() or getPixel32() (I've tried both) I seem to be getting values which are slightly inaccurate compared to what was saved. For example a pure white pixel which should be read as 0xFFFFFFFF often comes out as 0xFFFFFFFE. The behaviour of the program is dependent on the exact value of the pixel so these errors usually break it.
Sometimes the problem is intermittent so seems fixed but actually isn't. Is it to do with the PNG format? I thouht png was lossless so should deliver accurate pixel values at all times?
add a 1 pixel border around the entire stage so it appears in swf?
View 3 RepliesIs there a way to retrieve the color of a generic pixel on the screen using the mouse pointer inside the Stage of Flash Player? With the getPixel method of the BitmapData class you can get the color of a pixel only if the mouse is over a bitmap image, but what if I need the color a generic pixel on the screen?
View 4 RepliesI am trying to make a panorama presentation (running across 5 screens of 1360x768 pixels each) and therefore I would like to make a stage resolution in 6800x768.
Flash CS4 Pro says no: max resolution 2880x2880 pixels. Is it in any kind of way possible to make a work around so I will be able to get the requested resolution for my panorama animation/presentatrion.
I am doing a custom function like TweenLite.to, but there is one problem. I cast that function on many objects. And they all move a little bit differently. It only happens when I don't do Math.Round(bonus_move). If I use numbers for example 0.58. It moves every stage child differently on about - 0.05.
Here's my function:
Code:
Select allpublic function moveTo(child, speed, px, py){
// configurable
var movement_accuracy = 20;
var delay_duration = 2/(movement_accuracy/10) ;
var movement:Timer = new Timer(speed*12.5*delay_duration, movement_accuracy);
movement.addEventListener(TimerEvent.TIMER, timerListener);
function timerListener (e:TimerEvent):void{

I am trying to make a so called pixel effect in witch I want to make a shape only from pixels that are positioned in some random place on the stage. And all these pixels move to a certain point and create that shape. I've been looking into BitmapData Class but I don't now if that is the best way to do it.
View 2 RepliesI am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()
View 2 RepliesI have one that's almost done and the stage size is 700x800 px. But I'm starting to worry if that's going to look too small? To change it, will be a lot of work - there's animation, imported Jpegs etc. As far as I can tell, in order for it to look correct in larger dimensions I will need to basically create it again from the ground up. So, I'd really like to get an idea of what the optimal pixel dimensions would be for ecards to run on multiple platforms.
I really want to do this and I don't feel like I can move ahead until I get the viewing size correct. I don't even mind redoing the card. I just want my future cards to be the correct size. I don't want to have to come back and redo them all. By the way, the cards are being made in Flash. The site itself will be created in DreamWeaver.
I have a 100x100px image. I want to get 1 pixel vertical line from x- 1 to 100. How can I do that?
View 7 RepliesI have a greyscale image and I want to scan the pixels out of the Image and this is what I get :
var i:int;
var j:int;
for (i = 0; i < img.contentWidth ; i++) {
for(j = 0; j < img.contentHeight; j++){
pixeldaten.addItem({x:i,y:j,pixel:bmd.getPixel(i,j)});
}}
But the table doesn't look like RGB Values . (R , B , and G must be the same).
So, I'm using the BitmapData class and getPixel to retrieve the colour of a pixel. It works fine and returns a number like "16706965". I'm not sure what kind of value this is? If I place a 'toString(16)' on the end of it, I get a HEX value, but sometimes it isnt 6 digits long, sometimes 5 sometimes 4, so I can't just convert it from HEX to RGB.
I can make this number into a string with 6 digits, but then it doesnt recognise when I try to convert it to RGB
I have two images, one overlayed exactly over the other. The image in front is what the user needs to see, but the user behind can be considered to be like a map with different fields of color on it representing different things.
What I am trying to do is that when the user mouses over the image, it reads (via .getPixel) the color info of the image behind which prompts certain messages to be displayed.
I am not having a problem with getting .getPixel() to work since when I just have the behind image (colored "map") showing, the color data for each pixel comes up as expected. But, when I overlay the top image, it shields the back image from being able to be "read" by my .getPixel function.
Is there a way to have a movieClip not "interfere" with movieClips that lay behind it in the stack?
I am having a few issues converting a MC to a bitmap. I have succeeded in loading a graphic from the library, loading that as a bitmap and I can use getPixel to get the color at a certain x,y point.BUT I have another part to the problem. I have a file upload where a user can upload an image and choose a color off that logo. So I have the logo uploading, then getting loaded into an MC on the stage and it all works honky dory.However, when I (thought) I was converting it to bitmap and then use getPixel, every part of it is just returning white.[code]But no matter what co-ordinates I put in, I always get white.
View 7 Replies(1) read in a *.png image(2) when the user mouses over the movieclip that contains the image, an RGB value (in 0xFFFFFF format) of the pixel which the mouse is currently hovering over is displayed.Here is what I am doing to try and make it happen:(1) Using the loader class (imageLoader) to load a bitmap (*.png -- no alpha) into a movieclip.(2) Also taking the "imageLoader.conent" and placing it into a "grainImage:Bitmap" object.(3) Using a timer event to fire off data describing the where the mouse is at all times.function readPixelColor(te:TimerEvent):void { trace(grainImage.bitmapData.getPixel(mouseX, mouseY).toString(16));};How can one insert code in these Forums? I used to be able to do that... Oh well, the problem that is happening is that the value that is being returned by this function is off by 010101 (I believe, not certain how hexidecimal works).
Anyway, if the color is really "336699" (as confirmed in Photoshop) my function returns "326598". Which is "336699" minus "010101"why this may be doing this? Are my values "shifted" in some way since there is no alpha? Maybe there is some sillyness behind loading the image into a _mc and also placing the loader content into a bitmap object -- they are interfering with each other in some way?
I'm trying to create a color picker using getPixel. It works wonderfully as long as the image is loaded from a local drive. When I try loading it from the server (a subdirectory on the same server as the SWF), the loaded image doesn't get drawn when I use the draw command. It draws a white rectangle and when I use getPixel, I always get 0xFFFFFF. I also have system.Security.allowDomain("[URL]") in my script, but nothing works.
View 6 RepliesI am trying to loop through a bitmap and determine if each pixel is lighter or darker than gray using getPixel(). Problem is, I am not sure how to tell whether the value returned by getPixel() is darker or lighter than gray.
Neutral gray is about 0x808080 or R:127, G:127, B:127. How would I need to modify the code below to accurately determine this?

I've created a simple drag-and-drop dress-up game. The aim is that users will create a monster by dragging and dropping, and that an image of that monster will be sent to me, and I will create a toy that looks like the monster.
So once users are happy with the final look, and have filled in their details on the page, I would like them to be able to click a button that will send me the encoded jpeg of how the swf currently looks. I could then recreate the image using image magick or something similar, I guess?
I realise that this may require PHP, but as I have never used it before I thought that perhaps it may be possible to use getpixel to get an encoded text string of the stage and then send that to myself via "mailto"?
I'm building an application where the user can upload a photo of their head, scale it and position it, and then pick a colour from the photo.The photo gets put into a movieclip called 'head'I'm stuck at the colour picker part and I just can't seem to work out the whole bitmapData thing. Here's my colour picker code -
ActionScript Code:
private function beginColourPick():void
{
_bmd = new BitmapData(head.width, head.height);
[code]...
This code kind of works, but not correctly.
Problem #1: The colour picker only works in the bottom right quarter of the image because I moved the head mc so the registration point is bang in the middle. So the problem here is that I can't figure out how to move the bitmapData in line with the head mc.
Problem #2: If the user scales the head mc (even a tiny bit) the colour picker stops working altogether. Now I'm thinking I've got to use a transform matrix - but I read up on it and haven't got anywhere.
I'm working with a video in Flash where I am capturing each frame and testing the color of a single pixel. I'm using it to determine when a white/transparent background changes to be a color. The following AS2 code works flawlessly when I preview it in Flash and on my desktop in the browser (the direct SWF and placed inside HTML using SWFObject) but as soon as I upload it to my server it fails and produces "FFFFFF" continuously regardless.
this.onEnterFrame = function()[code]..........
There is no difference in the files; they are both pulling from the same video source (hosted on an Flash FLV server).The only difference is one set of files is hosted on my local computer and the other is hosted on my web server.

View 2 RepliesI was wondering what the code to get something to go to a whole pixel value is. I'm using pixel fonts inside of a movieclip and when the movie clip is moved through actionscript and lands in a different spot with easing, the fonts look bad because i suspect that they are no longer on pixel values.
View 9 RepliesI made a menu by attaching movieclips and specifying the text as a variabel. the main movieclip is called meny, then I attach the movieclips txt and pil (pil is norwegian for arrow) inside it, and specify the y pos. This works on my mac, but when I see it on a PC the text is down by aprox. 5-8 pixels.

How do I programatically get the pixel dimensions of my SWF. I tried using stage.width and stage.height, but this seems to be a tight bounding box on all the objects in the video, not the actual viewing area. I also want these pixel dimensions to be accurate as javascript dynamically resizes this SWF.
View 2 RepliesI have a Flash CS3 movie (AS2) wich uses pixel fonts. The text is within a movie clip that uses the tween class to move with ease. Whe I publish it, everything OK, the text looks very crispy. But I want this movie to be centered in the browser window so I've used the tags <center> </center> in the html file as you can see below. When you play the movie it plays in the center but... with IE8 the text is blurred if the browser window is maximize, but crispy if you minimize the window!! With other browsers it works well with all windows sizes, IE7, Firefox, Safari...
