Flash :: Erasing A Specific Selected Portion Of A Bitmap?
Apr 20, 2011I have two layers namely topLayer_mc and bottomLayer_mc. The actual vector drawing is drawn on the top layer and onmouseUp of the tool, a bitmap copy of the vector graphics on the top layer is taken and added as a bitmap to the bottom layer. The top layer is cleared subsequently. It is working for the pencil tool.Now I need to create an eraser tool. This is where things get tricky. In the application there is an option to save the image as png, so alpha has top be preserved. So the coventional method of draw a brush using the vector and using the draw method of bitmap will not work. Of course, on a visual level it would work if the brush drawn using the vector is to have the same color as that of the background.
What I need is to excatly erase the pixels.Now I have created a brush tool using the conventional technique and clearing is possible but what I need is to exactly erase the pixels. Is there some technique to draw this ? This is the code that I am using: I have also uploaded the swf and source code, When trying out, please draw all over the stage using the pencil (press Pencil button and start drawing)The source fla is also provided.

View 2 RepliesFlash :: Determining Visible Area/invisible Area Of A Masked Object?
Sep 29, 2011I have a movie clip named circle_mc(see the image on the link below) and a mask object(movie clip) which determines visible area of the circle. User can change the portion which is visible (extend the red area and make it red+blue, gray area is invisible). I need to find proportion of visible area to invisible area (red+blue/gray) so that I can calculate angle.
View 1 RepliesPhp :: Dynamically Change An Image From An Admin Area?
Mar 9, 2011Here's the deal: I am working on a site that provides information for art buyers. Pricing, where to buy and things like that. The page is done in php, mysql, and some jQuery here and there.One of the things they want to implement is a live stream of auctions. What they want is something like this:Where on the left you'd see the stream -instead of the black block- and on the right, the image of the work that is currently being sold, with the artist name, title and price. That's what The image on the left should change as the auction progresses.What I need is to have and option in the admin area on the page, where the administrator can select the image to display. So, to implement this, I would need to:Connect to the database to get the information: pictures, data, etc.
Loop trough the record to get a list. From that list, the user will select the image he wants shown on the webpage.Have the admin area send the image to be displayed to the page, and have the page change it dynamically, without the user having to refresh the page.The first two points are no problem, what I'm not quite sure how to do is the third one. Flash? Some from of Javascript? I leaning towards flash, but anything will do. I'm sure what I'm asking for is nothing that hasn't been done before, but my google-fu has failed me on this one. I don't need copy and paste code, if you could point me to a tutorial on this, or the basics tools I'd need, that's great.

Dec 13, 2011I have two backgrounds on different layers, and an object that can be dragged around. What I want to happen is that an area around the object should be transparent so you can see the background behind the first background, and when the object is moved, the transparent area should also move. Kind of like a "see-through" effect.

ActionScript 2.0 :: Dynamically Creating Transparent Area On Movieclip
Aug 1, 2007I have a .jpg graphic in a movieclip on layer two (1024/768). This is used as a background.I have a .jpg scrolling movieclip on layer one. It is a very wide graphic used for displaying a panorama.I would like to be able to create, dynamically using actionscript, a transparent area on the layer two movieclip (create a window) to view the underlying movieclip.I believe this is possible using the Rectangle class in the flash.geom.rectangle but I can't figure out how to attach it to the layer two movieclip or how to make it transparent so shows the underlying scrolling graphic.

Actionscript 3 :: Erasing A Layer Where Mouse Is Over It?
Jul 18, 2011I got the following question.
i added the following elements to the stage:
homeBg = new HomeBg();
homeMask = new HomeDrawBg();
addChild(homeBg);
addChild(homeMask);
I allready instantiated them in the beginning of the document. But my problem is the following. the homeBg layer is a image, the homeMask layer is the same image but it has a pencil scetch look. What i want is that wherever i move my mouse, the homemask layer should be erased so the bottom layer becomes visible(only where the mask is erased). So how can i tell the mask layer to erase itself if the mouse is over it?

Mar 20, 2009I'm in need, again, of some assistance. I'm making a game with 2 pictures. and the concept is built on that you erase part of the top-bitmap to see the bitmap under.How can I accomplish this?I tried to wrap my head around the bitmaps and the draw and the FillRect but can't get it to work completely.Basically I want 2 bitmaps, and a cursor which erases parts of the top one to show the one underneath.

Nov 10, 2009I am trying to erase one movieclip from another using the blendmode="erase" setting, but can only get it to work on the stage as the parent. This means it erases a hole through everything! The attachmovie also doesn't seem to work as I was expecting and I was hoping that when you drag the movieclip, the attached clip would move with it? If you check out the FLA [URL] you can see whats happening right now and what I want to achieve (diagrams provided in FLA).
View 1 RepliesActionScript 3.0 :: Erasing A Circle From Bitmap Data?
Sep 29, 2009I'm trying to create sort of an eraser to remove sections of a bitmap on stage.
I have achieved this by creating a MovieClip in flash that is a circle and exporting it as a Class called Hole.
Now I use this MovieClip to erase a circle section of the image using the following.
var mat = new Matrix();
var ct = new ColorTransform();
var hole = new Hole();
mat.translate(x,y);
image.draw(hole, mat, ct, "erase");
Now what im trying to do is scale the size of the circle depending on a certain variable but no matter what I try the scale doesn't seem to change and. The size seems to stay the same as I drew it in Flash. I tried adding the following line
hole.width = hole.height = size;
I even created a class file called Hole and the size as a parameter
var hole = new Hole(200);
This didn't work either it still appeared to have the same size. I have even tried altering the scaleX and Y values with no success.
ActionScript 3.0 :: Slow Performance With Bitmap Erasing?

ActionScript 3.0 :: Pixel Have Changed To Get The Percentage Of The Complete Erasing?
Feb 2, 2010I'm working with Threshold on BitmapData class. I need the threshold return the modified pixel (the pixels match with the equation).I need to detect how many pixel have changed to get the percentage of the complete erasing! I did it with getPixel32/setPixel32 but it's faster with threshold (i'm doing it on 15 bitmapdata at the same time)
pixelChanged += bmp.bitmapData.threshold(bmpBrush, bmpBrush.rect, new Point(this.stage.mouseX, this.stage.mouseY), ">", 0);
so, each pixel bigger than 0 should match this equation ... and they will be set to 0 after that (default color value). Next time, because they are 0, pixels are not suppose to change again because 0 is not bigger than 0 ! But it still return me a value, like if the pixel have changed! I've tried with different combinaison of mask/threshold .I join a sample of my problem (drag the triangle and check the output window ... the number increase even if the pixel is transparent 0x00000000)
ActionScript 3.0 :: Coloring (or Erasing) An Object And Checking When Complete

ActionScript 2.0 :: DragOver - Drawing White Line By Erasing Dots
May 19, 2010I have the raster of dots on white background. I would like it when I DragOver each dot it becomes white so it looks like you are actually drawing white line by erasing the dots. Ive somehow found the way how to do it by making it transparent when I rollover. But it doesnt work with dragover. How to do it only when I hold down the mouse button and drag my mouse over the dots?
This is the script assigned to MC with one black dot (I copied this MC with one dot into another MC and multiplied it to have the raster):
this.onRollOver = function () {
this._alpha = 0;
} this.onPress = function () {
this._alpha = 50;
}
I've tried also this, but it doesn't work:
var erasepoint = false;
this.onMouseDown = function(){erasepoint = true;}
this.onMouseUp = function(){erasepoint = false;}
this.onRollOver = function () {
if(erasepoint){
this._alpha = 0;
}}
