i know i should probably be more specific here, but what my problem is that i want to make something were when mouse is button is pressed a pixzel is created. now i assume you use bitmap data setPixel function. but i don't know how to set it up so you can zoom in as well.me. i'm trying to set it up this way because i want to be able to save it as an image.because i tried it once before but after i had done all this i windedup not being able to save the image properly. it turned out having anti-aliasing around all the pixels.
View 3 RepliesI'm looking for a way to get all of the black pixels from an image that I load in. This is in order to make all of those black pixels transparent.
View 4 RepliesI got one bitmap with a (almost) one color background. i need to change all of this with pixels at same x,y from another bitmap.
I know i need to run it through a double for loop and then into an if sentence.
like this:
If (color at x,y is > redvalue && color at x,y is > greenvalue && color at x,y is > bluevalue)then exchange with pixel from the other bitmap.
I know that I can collect the pixels of a rectangular area within a Bitmap using getPixels(), but is there a way to collect the pixels of a polygonal area with more than 4 points? Or at least determine whether a particular pixel lies within a polygonal area of a Bitmap?

var threshold:uint = 0x00FFFFFF; // all white Pixels

I am using bitmapData and bitmap classes to render a mouse cursor on the display screen. The bitmapData consists of an area whose colors should be inverted according to the background color. This is a very basic thing which could be observed with text cursor(the vertical line with two small horizontals on top and bottom), when moved over the text area. want to be able to do the same with the pixels in my bitmapData, is there a way to find out the background color effectively and invert the color values? In this process i will be redrawing the whole pixels, is there any other efficient way to do that ?
View 1 RepliesI would like to somehow loop through bitmap data and detect white pixels.. If i find a group of white pixels forming a big enough area (lets say 300x120) i would like to somehow ad text to that area..
View 9 RepliesI am trying to use the bitmapData.setPixels method to set certain pixels in the bitmap transparent.But no matter what I do, it always seems to set the pixel(s) black (non-transparent).Here is my code:
[AS]
bmpd = new ImageFromLibrary(0, 0);
bmpd.setPixel(0, 0, 0x00000000);
[/AS]
why its not setting the pixel(s) transparent?

basically what i would like is the end point to be the start point and the start point the end point.
I have a swf file that loads into my main movie, and within that swf there is a masked image that i would like to scale using zoom in and out buttons and also by using a slider bar.However i cant find any tutorials that will allow me to combine the two.I have used the following code for the buttons. Which seems to work ok but i would like it to be a little smoother. (using speed or some sort of easing??)
ActionScript Code:
zoomPlus.onRelease = function(zoomIn) {
if (test_shirt.shirt._xscale == 400 && test_shirt.shirt._yscale == 400) {[code]....
but for this code it keeps shrinking my initial object down to 10 pixels by 10 pixels..
I have a movie clip called column1_mc. when I click a button I need to move the movie clip in incremental moves consisting of 30 pixels.
column1_mc._y = 30;
Does not work because that is giving a _y coordinate.For example.I need to make the movie clip jump to _y 300 but make 10x30 pixel incremental jumps. Moving 10 times 30 pixel jumps.

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.
[Code]....
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),
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 working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap. This introduces an issue though: the second player would override all data the first player has put into to bitmap...My basic debugging proof of concept:
Code:
// bitmap test
import flash.display.Bitmap;
import flash.display.Bitmap;[code]......
I have a bitmap which has several frames (packed along the horizontal axis). In order to render them I copy it to the backbuffer (larger bitmap) as follows:

In pure AS3, I have a pixelbender and a large bitmap. The pixelbender is configurable with a distance parameter to affect only a small area of the bitmap.

Is there a way to write a bitmap font right into the bitmap being desplayed? Mabey better worded: myBitmap.draw(image, t) draws a picture is there a way to draw text? I'm stuck even if its just a work around in some way I would like to know... (the current work around i have in my head is writing it in a movieclip turning that into bitmap data and drawing it... esentially creating a prototype answering my question... but a built in way would be easier probably).
View 2 RepliesIn AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.
View 2 RepliesI'm using Sandy to animate some objects in 3D. What I currently do to images which are EXPORTED in the library, I want to do to some bitmaps that I create using the DRAW technique. But it wont work :-(
CODE FOR 'CREATED BITMAP' :
ActionScript Code:
var bData:BitmapData = new BitmapData(myObject.width,myObject.height);

Sandy doesn't seem to treat the 'created' bitmap the same as those that are exported from the library.
A friend of mine has a Flash Action script running on a LAMP server that currently reads an xml config file. He's asked me if it's possible to remove the xml file, and replace it somehow with a system (lets call it an 'auto xml generator') that intercepts the request to read that file and generates an output, so it appears to all intents and purposes as if the file still exists and contains the contents that has actually been returned from our auto xml generator'
