Is there any algorithm to perform erase operation in a bitmap? I would like to create functionality similar to how photoshop or other graphic application performs erase. Is erase operation so difficult that there isn't much help (for bitmaps) available? I am OK even with name of an algorithm, I can proceed from there.
View 2 RepliesIm building a pretty simple drawing board in flash, i got this code from this forum and it works fine (there is more to it but this is the drawing part)[code]This works fine. But i want to be able to erase the drawings, step by step this is ths tricky part, ive looked everywhere(ok not everywhere) but in a whole lot of places but the only thing i found is how i could delete everything with removeChild and that in not what i want. Maybe i need to change the function abowe? Please help me to get in the right direction. What should i read about /look at?

View 1 RepliesI have an object in the library that is linked with class Myclass, I define MyClass in its own AS file and everything runs ok, but as soon as I remove the linkage of the object with the class the compiler generates an error with a seemingly totally different class, that class is part of an open source data structure library for AS3, unrelated to that library object or class MyClass.
The error code is 1044: Interface method ****** in namespace ******* not implemented by class ********.And of course I checked and the class implements the interface methods, all of them so there should be no errors.The library I'm using is a [URL] and the class reporting errors is HashMap and HashTable.
Something that is similar to the Cover Flow in iTunes.
I can use Adobe Flash, Flex, or pure html/javascript.
HOWEVER, I need a pointed to production ready code. I've looked at plenty of examples in both Flex and HTML that aren't ready for prime time. No demo code needed.
Here's my requirements for production ready:
1) Memory leaks are under control.
2) Works like a river with larger data sets, paging in sub-sets in some set number. The component/code needs to be able to handle 100+ items to flow through, preferable up to 500.
I keep getting this error when I try to implement an interface:"Interface method bar in namespace Foo not implemented by class Test".As far as I know, I've correctly added all methods from the interface.[code]I'm using mxmlc.exe to compile in the flex sdk.

View 1 RepliesI've searched and racked to no avail.. so, does anyone have an algorithm to create a concertina type rectangle, ideally horizontally. The desired effect is exactly like that of normal horizontal Window Blinds (assume they're closed- doesn't matter) of say 30 parts (or slats) of equal height and uniform width.
When such a blind is raised half-way up notice how the parts at the bottom go from dead flat to an increasing value in height, with perhaps the top-most part hanging normally.
Similarly, when the whole Blind is all the way up, all parts are flat. Conversely, when the whole Blind is fully extended, all parts hang at their own, uniform height. It's this "slightly differing but related to my neighbors height" I'm stuck on.
my program calculates ax,ay -> using this variables -> vx,vy -> after that I calculate the little step that my mc will make, in other words I calc x,y position [code]as you can see all depend on each other...but the problem is that after getting new x,y I want this x,y to be used to calculate next step!fo every new coordinate I want new vx,vy ax ay!
View 8 RepliesIf I have a sprite, with which I have drawn some stuff, how do I erase part of what I have drawn? Preferably I could use drawRect with some "alpha=0" paint. However, I don't believe beginFill lets you set an rgba color (like you can in bitmapdata). Setting alpha = 0 in beginFill doesn't really do anything -- it just draws nothing. In my particular use case, masking isn't an option. Also, calling clear() isn't a good solution since it clears away everything.

how to perform a search in XML, so I use the above method, kinda hard code I know...for example, I try to search " keyIn:String = "BR1014"; " means I wanna search BR1014 in 4 XML files, so I load the XML info into an array, and using for loop to loop the XML array (in this case TitleArray1[i], TitleArray2[i]...) and compare it with keyIn (which store the value BR1014), some how the value is located in TitleArray4[i] which have the length of 12 (trace(TitleArray4[i].length) = 12)
so everytime I run it, I will overwrite abc 12 times... and out put 12 time the abc value, in this case BR1014 was located in TitleArray4[3], so the 4th output of "abc" is BR1014 but others is all 999...
I recently saw "Remove or Reuse" by badaboom, in which he set the the invader instance to "null".In my constructor, I have a sprite variable as [code]When the user clicks the start button, the trail sprite is used.[code]After the user click the start button, a timer starts and the trail is drawn [code]Since this is a simulation, the user will want to erase all the trails drawn at some instance to show new examples. In in the reset button, if I set:[cod]Then do I lose the trail variable? Because I need to re-use it later in the start button and in the timer. I also learned somewhere that garbage collection only collect when the variables does not link to any other instances. In this case, the trail is still sticking onto the container_mc right?I have tried container_mc.removeChild(trail) alone, but when I addChild(trail), none of the trails drawn are deleted.

I have a picture in a BitmapData object. And an array of points. I nead to erase the part of the picture inside a polygon specified by the points. In other words, draw a polygon specified by the points and fill it with transparency.
I have a Sprite that I draw into using lineTo. Later the sprite is drawn into a bitmap to add to a mask. That works great. The issue is erasing the vectors in the Sprite once they are drawn.
To draw I just do something like:
userDrawing.graphics.lineStyle(12,0x000000,1);
userDrawing.graphics.lineTo(mouseX,mouseY)
[code].....
I need a short code for erasing lines drawn on an Android device. This is the code that generates my line:
this.graphics.lineTo(event.stageX, event.stageY);
I cannot seem to get the code right for erasing this line with movement detected by the accelerometer. I want to shake it like an 'etch-a-sketch' to erase the lines.
If I press the button for the photogallery it creats new Objects, and dont erase it after i go back to main. So long its load all the objects in the memory and its exists all the time...

I also have an actionscript, in which I have ingArr:Array of ingredient strings.Now, I would like to realize the following queries here:
1) Select (all fields) one recipe which has the most of ingredients from the array. If more than one record have the same amount of matches, then divide the number of matches by total number of ingredients in recipe and return the one with the highest ratio. If there are no matches return nothing.
2) As above, but return 10 recipes with the most matches and do not perform check for equal number of matches. Sort the results by the number of matches.
