Possible to paint single pixel?

The Graphics class has methods to paint different object eg.:
drawOval(int x, int y, int width, int height)
but is it possible to paint just one pixel?

fillRect() can be used for that.Although it should be noted that drawLine() is faster. Of course, knowing that is only useful if you're drawing lots of single pixels.

JS/PS CS3: identify single pixels sticking out

In a bitmap, is it possible to identify single pixels sticking out from a shape? Let's say I have this black shape in a black-and-white bitmap:
   xxxxxxxx
   xxxxxxxx
   xxxxxxxx
   xxxxxxxx
        x
an 8 by 4 rectangle with one pixel sticking out from the bottom. Question is, can I find such pixels using a script (JS) and make it white?
Thanks,
Peter

Peter, I added the work around to the script. It appears to fix the problem. With my basic test files.

How to fill or erase a single pixel?

What tool or tools do I have to use to erase or fill a single pixel at a time?
Sincere thanks in advance for yourhelp.
Al

So many ways; you can use one or a combination of:
Brush Tool set to 1 pixel and a color that matches the area
Spot Healing Brush Tool set to around 3 or 4 pixels
Clone Stamp Tool set to a reasonable size based upon area and a soft edge (a graphics tablet like those from Wacom is a big help here due to being able to set size and opacity; pen pressure determines size and/or opacity as you paint)

No iPhone apps have access to the necessary API's to do so...they're all sandboxed.

How to copy and paste a single pixel

How to copy and paste a single pixel
I want to copy a single pixel and then paste it in the
position of
another pixel in the same image.
(This is in effect changing the colour of the target pixel,
isn't it.
But in my case copying an existing pixel seems simpler than
selecting a
colour from the swatch or using the colour picker.)
What is the most efficient way of doing this?
I tried to select one pixel with the marquee tool. Then
copied it with
control-C, but then how do I select the target pixel and
paste with
control-V?
Thanks for your help.
Adrian

Is this possible in a single query?????

While I don't think this is possible in a single query, I definately don't have the background the experts here have.
I have a request to identify all shipments in a period/range of periods that have a payment transaction. For those shipments, the user wants a list of all payment transactions and the initial accrual entry listed by period for potentially a large range of periods. The accrual and payment entries are identifed by the same characteristic and a 0Amount key figure contains the values. A couple methods I have tried I have listed in previous threads with either errors or the query blowing up with what appears to be a cartesian product issue.
Anyone done something like this who can provide pointers.
Bill

Hi Bill,
Why dont u use RRI-report to report interface for this Requierment ??
There are lots of threads on RRI ,just follow them and u can satisfy this requirement.
1)Query A for Shipments
2)Query B for Payment Transactions.
Call report B from Report A
1)GOTO RSBBS
2)Create New
3)Sender Query Give the First Query Report A
4)Below sender Query there is Receiver Query  give the RRI query report B (The query which u want to call).Report type should be BEX ,and Target system--Assign the System(Local) and in the report give the Report B.
5)In the Report A check whether in the GOTO -u get the Receiver Query ,i.e Report B.
Hope this help !!!!!!!!!

Any possiblity to use single Inbound Service Interface with multiple Receiver Agreements

Hi All,
Scenario: PROXY to FILE.
Requirement is to receive to two locations.
Is it possible to use single Inbound interface with multiple Receiver Agreements. I tried using two operation in the Inbound Service Interface, and Operation Specific in Determination. But couldnt proceed further. Do I need to use seperate Service Interface for two receiver locations?
Please suggest some solution.

Hi Naveen,
There is a possibility but in the case in the same server location with dynamic configuration: Placing file in two different directories using single receiver communication Channel
With different location you would need to develop a new adapter module as Amit Srivastava explains and develops here Send File to Two Different Locations using Adapter Module

I have a single Pixel that is broke on my 2 month old retina macbook pro. I have Apple care. What will Happen if I bring it to an apple store.

I have a single Pixel that is broke on my 2 month old retina macbook pro. I have Apple care. What will Happen if I bring it to an apple store.

You can try to see if they will replace it, however there is some sort of acceptable amount of stuck pixels and they won't replace so I hear.
But that was a long time ago and things change.

Is it possible to show single dimension of measure value in Chart

Hi all,
              By using BICS connection(BW-Bex Query), developed Application(dashboard) through sap design Studio 1.2 sp01. My requirement is Measure is Purchase OrderValue, and dimensions are x,y,z, and P. When Open application it has to show X-of Purchase Order values in one Chart,Y-of Purchase Order Value in another chart..like we need to show X,Y,Z and P values in different chart. How we can achieve by using single data source.
Thanks
Ram

Hi Tammy,
          Thanks for your quick reply. You are right.. we can create multiple views to show separately. but due to performance issue..is it possible to use single view to finish my requirement?
Explanation: i have 4 charts
1 chart: In X-Axis need's to show X-Values and in Y-Axis need's to show PO value
2 chart: In X-Axis need's to show Y-Values and in Y-Axis need's to show PO value
3 chart: In X-Axis need's to show Z-Values and in Y-Axis need's to show PO value
4 chart: In X-Axis need's to show P-Values and in Y-Axis need's to show PO value
            here X,Y,Z,P are dimensions(fields).
                unable to add image..
Thanks

Cropping problem: crops to a single pixel

I select part of the image using the crop tool, but when I execute the crop, the result is a single pixel, regardless of the size of the cropping box

reset the values in the options bar. You will find they are set to 1. CS3 has a mysterious tendency to do this on its own.

How to add Event to every single pixel with BitmapData?

What I want to accomplish: when I drag the cursor over a sprite I want the sprite to break down and every single pixel moves through the screen at random x and y axis.
To make it simple the draw this is what I want but with much more fragments(pixels) around, thousands of them. How come could I approach this?
Thanks in advance.

if mc is the object whose pixels you want to randomize and display in a bitmap:
var bmpd:BitmapData = new BitmapData(mc.width,mc.height);
bmpd.draw(mc);
var bmp:Bitmap = new Bitmap(bmpd);
addChild(bmp);
mc.visible=false;
mc.addEventListener(MouseEvent.MOUSE_OVER,randomizeF);
function randomizeF():void{
    var a:Array = [];
    for(var x:int=1;x<=bmpd.width;x++){
        for(var y:int=1;y<=bmpd.height;y++){
            a.push(bmpd.getPixel32(x,y));
    shuffle(a);
    var i:int=0;
    for(x=1;x<=bmpd.width;x++){
        for(y=1;y<=bmpd.height;y++){
            bmpd.setPixel32(x,y,a[i]);
            i++;
function shuffle(a:Array) {
    var p:int;
    var t:*;
    var ivar:int;
    for (ivar = a.length-1; ivar>=0; ivar--) {
        p=Math.floor((ivar+1)*Math.random());
        t = a[ivar];
        a[ivar] = a[p];
        a[p] = t;

Just a single pixel.

I can't find a method in graphics or ghraphics2d that will allow me to change a single pixel in the paintComponent method. the best I can do is a very short line (g.drawLine(x, y, x, y)). surely a method like this would call a method that draws a dot, but I can't find it. a little help please.

This is just my 2 cents.
somebody must know more about the 'graphics' class,
and how the drawLine method is programmed - it must,
itself, draw one pixel at a time.Well, maybe not. A Java implementation does not talk to the hardware. It will generally have to call some native method that calls a 3rd party graphics implementation (X, WinG, Direct Draw, etc. ), which in turn could call another level of abstraction... including the driver and eventually hardware. There's no guarantee that a 3rd pary API or interface will have a "drawPoint(x,y)" method on ever conceivable OS and graphics configuration. Furthermore it might be the case that a particular optimization occurs in the hardware level. Maybe some graphics hardware is only capable of drawing "lines" even if they are only 1 pixel long. Certainly hardware accellerated 2d and 3d graphics aren't drawn 1 pixel at a time at the software level. It makes sense that a filled rectangle should be done at hardware level, probably evel lines.
Probably the most overhead here is putting 2 extra values on the call stack.
Anyway, I think the old saying about premature optimization is as true here as it is otherwise. If you can actually show with the use of a profiler that an application's bottleneck is the Graphics.drawLine method, and that there's no more efficient way to write the app, THEN we have a problem.
Or satisfy your curiosity:
public static void main(String[] args)
        int trials = 30;
        int loops = 20000000;
        long cummulative_2parms = 0;
        long cummulative_4parms = 0;
        for (int i=0; i<trials; i++)
            long t;
            //2 parms
            t = -System.currentTimeMillis();
            for (int j=0; j<loops; j++)
                two_parms(j, j);
            t+= System.currentTimeMillis();
            cummulative_2parms +=t;
            System.out.println(
                    "2 parm ms: " + t + "\n" +
                    "cummulative " + cummulative_2parms + "\n");
            //4 parms
            t = -System.currentTimeMillis();
            for (int j=0; j<loops; j++)
                four_parms(j, j, j, j);
            t+= System.currentTimeMillis();
            cummulative_4parms +=t;
            System.out.println(
                    "4 parm ms: " + t + "\n" +
                    "cummulative " + cummulative_4parms + "\n");
    static void two_parms(int x, int y)
    static void four_parms(int i01, int i02, int i03, int i04)
