ActionScript 3.0 :: .getPixel() Returning Incorrect Hex Color Value?
Oct 15, 2009
(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 have a color picker which I set usingMenu.ColorPicker.selectedColor = 0x339900;It displays the correct color when ran. If trytrace(Menu.ColorPicker.selectedColor);it traces 0. Why is this? Even stranger is later I set some xml parameters using
Let's start with the following XML: Code: <swatches> <swatch> <swatchName>Plaid</swatchName> <swatchColors> <color>black</color> [Code] ..... I want to return a list of the <color> values without having any duplicates.
I 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.
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.
I 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'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?
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.
i have a button, with instance name lightblue_color. I am assigning a color to its color field like this: lightblue_color.transform.colorTransform.color = 0x65ffff; then i am adding an eventlistener to the button like this: lightblue_color.addEventListener(MouseEvent.CLICK, ChangeColor); Then, in the function: public function ChangeColor(evnt:MouseEvent):void {trace(evnt.target.transform.colorTransform.color);} It prints 0. Why is that? Shouldn't it print 0x65ffff or do i need to do some type conversions?
CS4 was working fine for a few weeks, then yesterday I opened an FLA and got an error pop-up that said "Parameter is Incorrect". The error happened for all FLA files. I could save changes but could not preveiw or publish (same Parameter is Incorrect error as on starting CS4). I even made a blank FLA and it wouldn't work either.
Relized today during more testing that this error only happens any time I open a file that is on my desktop (running XP). Same file moved into another folder (Even desktop ewfolder) works fine.
I'm doing a little flash nav bar and I'm trying to have the buttons link to the correct web pages. My code is extensive and I'd rather not post the whole thing in here so I'll try to be as concise as possible.Basically I'm getting this error:1137: Incorrect number of arguments. Expected no more than 1.Everything was running smooth in my script until I added the URL requests here:[code]Is the syntax incorrect or something? Again, everything was fine up until I added those two at for case 0 and case 1.
I'd been using flash cs4 fine for a few weeks before this happened but in the last few days whenever i save a file i'm working on i can no longer preview it (by preview i mean ctrl + enter) my cursor turns to the symbol to show it's working for a few moments but once i move the mouse this goes back to being my normal cursor. Whenever i try and publish a file i get the error "Parameter is incorrect". Before i save the work the file previews fine and even blank documents that i start and immediately save will not allow me to preview or publish them following the save
I'm running w7 64bit on a quad core with 4gb ram. I've tried uninstalling and reinstalling but this hasn't helped. My flash professional cs4 is also fully updated.I've attached one of my .fla files that to me i can't use properly anymore, it's just a basic animation of squares forming the words 'enemy down' on a black background.
I am using AS3.0.I have created simple forward naviagtion from my homepage to my second screen using the code below and a simple button (click1)
//handle events for buttons... click1.addEventListener(MouseEvent.CLICK, clickSection1); function clickSection1(evtObj:MouseEvent){[code].......
Slightly modified code is used on consequent pages to navigate forward through my site.I have also created a home button that navigates me back to my first screen (called screen2) using the following code...
home_btn.addEventListener(MouseEvent.CLICK, clickhome1); function clickhome1(e:MouseEvent):void {gotoAndStop("screen2") }
However, when I return to the homepage and click forward, instead of taking me to the next page and the next page, it jumps me forward directly to the 5th. screen.
The braces shown below after ...ret):String are incorrectly being highlighted as red I'm using the following syntax definition file for actionscript: [URL] 2 Questions: Does anyone happen to know off-hand what causes this weird matching? Is there anyway of identifying the current syntax matching group under the cursor?
I must be in space suffering oxygen deprivation because I can not remove this error nor understand why it is occurring."1136: Incorrect number of arguments. Expected 1."
package bna{ import flash.display.Sprite; public class BNALesson extends Sprite { public function BNALesson() { var sX:int = 16;
I'm trying to make a simple slideshow that ends with the option to click and enlarge each image. Clearly, I'm a complete n00b at this and know nothing about coding.
Here's what I've done:Created the slideshow. It works. Created a thumbnail of each picture and made it into a button (btn1, btn2, btn3, btn4) with the same instance names, each on their own layer. Created an Actions layer with the following code:
stop(); function rollOverFunction(evt:MouseEvent) { play();
[code]....
The code was working fine until I added the second button...now I get the error above.
When I have a function defined like this function stopDragging(e:MouseEvent):void{ stopDrag(); //and other stuff }
It gets called by various mouse events, thats fine. But when I want to call it like this if(some condition){ stopDragging(); }
I get an error 1136: Incorrect number of arguments. Expected 1. stopDragging(); And how do I get around it so that I can fire stopDragging from my if statement?
I have a game I'm currently working on and I've got some library movie clips with actionscript attached, the constructors for the actionscript files have several arguments obviously when I instantiate the movieclip via code with the new() statement I simply pass those arguments in no problem, but how do I pass in the arguments when I drag an instance to the stage from within flash. All I currently get is an error message "incorrect number of arguments".
I have an app that loads large imagery and swf assets on demand, presenting a movieclip that displays load status based on a ProgressEvent listener. When run locally and off of my own server everything looks as it should and I get accurate bytesLoaded and bytesTotal figures producing the correct load % displayed. However, when published to my client's server, the load status starts at 100% and doesn't ever change. The even stranger thing is that in Firefox it says 100% Loaded but in Safari it says Infinity% Loaded. Are there web server settings or differences I should consider here?
I am working as a teacher in Singapore and I am currently doing a project for our school. I am using the Adobe CS4 Design Premium. I am using Adobe Flash CS4 for the project I am doing. Adobe Flash CS4 crash often and after the latest crash and when I open up my project i got an error which is "parameter is incorrect" and when I press ctrl+enter, it didn't pulish the file and I have noticed that the swf file that was created before is gone after I press CTRL+enter.
I have a simple 3D tween that I created to 3D rotate a bitmap logo (in a movieclip) on it's x axis. It works great during testing but I noticed that when I tested it on the website that the pivot point was totally off! I had to use the matrix.prependTranslation() method to alter the pivot point so that the clip would rotate & remain centered. This is totally broken when I run in the browser but works great outside of the browser?
I am a Flash novice using the Flash Quiz template and trying to create multiple conditional incorrect feedback responses for each question. Currectly the array only has one asset dedicated to providing feedback for an incorrect response. Is there a quick and easy way to add two more conditional incorrect feedback responses?
