Alpha Channel Deteriorates On Scaling Image?
Sep 24, 2009Using Flash CS4. I have some images with transparent backgrounds that I'm putting into Flash. Placed in Flash at original size, transparency looks great. However, when I scale the images to any different size, the edges of the alpha channel get real rough, not smooth and aligned to object. I've experimented with png, targa, gif, but all seem to have this problem. Is this some issue with Flash? I don't remember seeing this problem in say Powerpoint.

View 1 RepliesVideo Encoding For Alpha Channel
Jan 20, 2010I am experimenting with video using the alpha channel capability of the FlashCS3. I followed the tutorial on the gotoandlearn website on how to create chroma keyed video. I exported an avi video file having removed the background. Ive used Flash video encoder for VP6 and flash player 8 with encode alpha channel ticked. However my swf is not showing the video, just a white blank where it should be. It puts out the audio only.
This is the log file.

ActionScript 2.0 :: Get The Alpha Channel Value From External .png?
Jun 7, 2007i can now getPixel() from a external jpg but what i finallly want to achieve, is getPixel32() the alpha value is always FF(255)
[URL] take a look on this sample~ in this sample the photo is partially transparent, i can see that in photoshop if i put my code in this file, the color picker can tell the alpha changes. that why i still think there is a chance for getting the alpha value from external .png~ just don'y know how to achieve it T_T (i've try transparent png and also alpha channel added png, doesn't work like the sample)

import flash.display.BitmapData;

IDE :: Alpha Channel And Mouse Events?
Nov 3, 2009I have some png images which were converted to movieclips and exported. I would like all clicks on the transparent parts of the png to be ignored by a movie clip on a closer layer and have a movie clip under the transparent parts receive the event. Is there a way to do this? When I convert the symbol to a movie clip, the authoring tool automatically puts a bounding box on it so all clicks in the bounding box are detected. I tried searching mouse events and alpha channel stuff on the forum.

ActionScript 3.0 :: Flash - Keep 'Alpha Channel' Data With PNGEncoder?

The code, or the encoder, or something is preventing or deleting the alpha channel data. What should be transparent is showing as white.

ActionScript 3.0 :: Flash Can PerlinNoise Control Alpha Channel?
Oct 17, 2011I'm trying to accomplish a similar effect as seen on :[URL].. I suspect its just perlin noise displacement with a loop on the DisplacementMapFilter to decrease/increase the distortion over time as well as an alpha tween. I have been able to spy that they are using caurina tweener, which isn't of interest to me.
Its the principle I'm after, not a copy of their effect. I'm trying to assign an alpha value to say, the White/Black area of a PerlinNoise generated Bitmap. Where the White would be 0% and the dark 100%. And have that White value increase over time so that the entire image, the filter is applied to, gradually fades into view.
Math :: Mapping Rect In Small Image To Larger Image (in Order To Do A CopyPixels Operation)?
Jun 16, 2010I'm coding in actionscript 3 - the functionality is: large image loaded at runtime. The bitmapData is stored and a smaller version is created to display on the available screen area (I may end up just scaling the large image since it is in memory anyway).The user can create a rectangle hotspot on the smaller image (the functionality will be more complex: multiple rects with transparency: example a donut shape with hole, etc)
3 When the user clicks on the hotspot, the rect of the hotspot is mapped to the larger image and a new bitmap "callout" is created, using the larger bitmap data. The reason for this is so the "callout" will be better quality than just scaling up the area of the hotspot.The image below shows where I am at so far- the blue rect is the clicked hotspot. In the upper left is the "callout" - copied from the larger image. I have the aspect ratio right but I am not mapping to the larger image correctly.[code].....
ActionScript 3.0 :: Maximum Of Loaded Png's With Alpha Channel In Attached MovieClips?
Jan 10, 2011On my stage I have 2 empty MC holders, each of them in a seperate layer. In the bottom mc holder called 'map' a map image is loaded from my XML file using MovieClipLoader. This works fine.
What I want to achieve is that on top of the map, 24 PNG images with Alpha channels are loaded into seperate MovieClips attached in MC holder 'projects'. For every PNG image a MovieClip from my library is attached in order to determine the hit shape of the PNG image. This works fine too!
However all of sudden my first 2 MovieClips with the PNG images in it dissapear as soon as all of the images are loaded. But when I roll over on of the other MovieClips they suddenly show up again and when rolling out they dissapear again!
It has nothing to do with my XML file nor my PNG images, because when I move my first 2 XML nodes (the ones that are dissapearing) to the end, 2 different MovieClips dissapear! It worked absolutely fine before but since I added 2 more MovieClips the problems started. It almost looks like I can't load more then 22 PNG images, but that would be extremely weird.
I tried creating the first half of the MovieClips in one MovieClip and the second half in a different MovieClip, but that doesn't change anything. But when I create the first half of the MovieClips in the _root and the second half in a MovieClip, only 1 MovieClip dissapears instead of 2!
I really don't get it. I'm totally confused and lost since I don't know what else I could try.
Here's my AS2 code:
Actionscript Code:
var pimage = new Array();var pmc = new Array();var ptitle = new Array();var phit = new Array();var ptooltip = new Array();var pmenu = new Array();var ptotal:Number;var phalf:Number;function fillProjects() { nodepath =

Oct 23, 2010I tried to playing around with the augmented reality. Therefore I watched the tutorial (http:url....) and all works like a charme to me. I replaced the kramer.m4v with my own video. It works perfectly.But I want to have my own video on a transparent layer.So that I can see myself not within the background of my video.Therefore I did a video on a greenscreen and keyed the background. All seems to be ok!I exported the video in an .mov with the alpha channel. It works so far, but the black background is still there if i hold the marker to the camera.so my question is: Is it not possible to export a mov with the alpha channel to let the background go away?
Any hints or workaround? I just want to have a video with me speaking on a transparent background and not with teh black background. I changed the kramer.m4v in the HELLOFlar.as to kramer.mov (its with my own video, just the name is the same) but the background isnīt gone
