Make a single pixel vertical column

I have a 1024x768 canvas and I want to draw two 1 pixel columns, one starting in column 0 and one in column 1023 (basically two tall white strips on the far left and far right)
how can I make this as a png which is transparent in the middle. I need to put this on top of another image and cover the left and right edges.
Is this possible with photoshop?

New Document: 1024 x768

Single pixel vertical line

Suddenly there's a single pixel white vertical line smack down the center of my screen, always there no matter how I boot up the computer. Any suggestions?

Take it in for repair.

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.

Vertical column pop-up button-"OPEN"-with left " " appears-bottom right corner Firefox screen-Independent of web-site visited-Am "secured" against virus-Have not touched button: "Danger, Will Robinson." Appreciate any help. Thnx. DanDeren

Occasionally and sporadically - I cannot reproduce this issue - a small vertical column-ed pop-up button appears in the lower right corner of my (Firefox) browser screen. It is not clear what causes this - I thought perhaps that it had something to do with Google's new gmail format which I have, so far refused to adopt, although when it forces me to do so, I Accept and then re-configure back to the old look. I don't think the problem is with gmail, though since tonight I was accessing the New York Time subscription web-site. However, tonight - 31JAN2012 - this button popped up, stuck around for maybe 30 seconds and then went away. It is small - about a quarter inch wide; perhaps one-half to three quarters of an inch tall. It displays on the top of the button the "<" followed underneath by the word "OPEN" (displayed vertically). I know better than to push an OPEN button whose function is absolutely opaque to me - fool me once... My desktop has the latest version of Firefox - 9.0.1 and I just loaded the latest update. I am running Windows XP Version 5.1 (Build 2600.xpsp_sp3_gdr.111025-1629 : Service Pack 3). Further info re. operating system: Microsoft Windows XP Home Edition Service Pack 3 - that was probably pretty clear from the Version and Build info above. Hardware: ACER-42041E6643 - ACPI Multiprocessor PC - Chip/Processor: Intel Atom CPU 230 @ 1.60 GHz (2 of these). I can provide more system and configuration information, as necessary. As it is, I go to System Info and it will not let me copy all of the system info above - I had to copy it brute-force manually. I have managed tech support organizations in the past. The first question you ask the user is: "What changed?" or perhaps "What did you change?" Like every other user with an issue, my response is: Nothing of which I am aware. I certainly am not going to push this button - perhaps it toggles between something and something else - more than like so - or it opens "something" - I will not find out what since I refuse to push it. I am guessing this is some benign "feature" of which I am unaware. Any assistance with this will be greatly appreciated. Thanks and best, Dan Deren.

How to display horizontally to vertically column in oracle

Dear All
How to display horizontally to vertically column in oracle,Please give me Sol. ASAP

Sunil,
Which column is the sal column? I canât see any numeric columns in your query. If you use htmldb_item calls in your query column, then this makes them strings and you canât build sums on string columns. If you want to build sums in an updateable report / tabular form, then donât use the htmldb_item API. Instead use the built-in display types on the report column attributes page. Using the built-in display types is the better options in most cases anyway and they do allow you to calculate sums even if the column is a text field or display and save type field.
Regards,
Marc

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;

Can I make a 1 pixel burn tool?

If I use a pencil, I can draw one pixel at a time. However, if I switch to the Dodge or Burn tools, even selecting 1 pixel width, it still is soft. One click effects 8 pixels. How can I truly harden the tool to only darken 1 pixel at a time?
Thanks

Sure...just load up your hard square brushes from Photoshop's brush presets.
But there's still a problem, that is: Even with 1 pixel hard square brushes, there's been a bug in Photoshop for years that causes the effect to extend out past the single pixel to the right and downward. In other words, you want to affect just a single pixel, but it will actually affect a 2px × 2px region, where the pixel your cursor is over is the one in the upper left of that 2 × 2 box. You may have to make a marquee selection to constrain your dodging/burning operation.
This bug affects all the tools that use the brushes.

Use 40 black 1 pixel x 400 pixel vertical lines, and create an experimental composition using varying vertical spacing?

Ive been pulling my hair out on how to do this all day and im getting no where i dont even know where to begin! Please help if anyone knows how to do this.

enforcer4u,
she said posting here if help was needed was a good idea...
This is Classroom in a forum.
I believe the first line should have read Use 40 black 1 pixel x 400 pixel vertical lines, and create an experimental composition using varying vertical > horizontal spacing.
One way (she may be following this thread, you know) would be to:
1) create a horizontal/vertical (composition Three/Four) line with the Pen Tool with a length corresponding to the whole composition and two or more Anchor Points, ShiftClickDragging at each with different lengths of the Handles;
2) Create a vertical/horizontal line by ClickDragging with the Line Tool (or just Click with the Line Tool and set the Length and direction, then move a copy (ShiftAlt/OptionDrag the original, start dragging a tiny bit before you press the keys);
3) Object>Blend>Blend Options, set Spacing to Specified Steps, 38 steps;
4) Select the lines from 2) and Object>Blend>Make;
5) Select both the Blend from 4) and the line from 1) and Object>Blend>Replace Spine.
Other ways include creating the first line and then ShiftAlt/OptionDragging to create the other lines up/down/left/right depending on composition, or creating or all the lines (maybe using the blend) and then ShiftClickDragging individual lines.

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)

Single page vertical scrolling website - first 'page' to fill browser

I'm creating a single page vertical scrolling website.
I would like the first 'page' to be a photo which fills not only the width but also the height of the screen.
Is there any way to make the box do this without simply making the box height very tall to accommodate for taller screens?
Thanks guys

How do I get Firefox to show bookmarks in a permanent, vertical column on left side of the screen?

IE allows me to bookmark my favorites and keep them listed in a vertical column on the left side of the screen--which I keep open at all times. Is that function possible in Firefox?

To open the Bookmarks sidebar, in the View menu select Sidebar and then Bookmarks. Alternatively use the keyboard shortcut Control+B

How do i make a single connection to handle video, audio and chat

I'm developing an application and i want to make one single connection for video(netstream) and chat(sharedObject).
I have one connection for each but i have limited connection availeble in the server so i need to make a single connection to handle the video net stream and chat sharedObject.
I use this urls to connect:
private var serverWebcamURL:String = "rtmp://myserverIP/live";
private var serverChatURL:String = "rtmp://myserverIP/multicast/chat";
What do i have to do to make this work?

Why does my Macbook Air make a single buzz/beep?

Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

Beeps on startup:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images.
5 beeps = processor is not usable

One pixel vertical line on new iMac 24" display - defective?

I have a one pixel vertical line that is fairly constant on my new (one week old) 24" iMac -- it sits there between the Edit and View mens mocking me, and runs the length (well, height) of the screen.
I've tried changing resolutions and resetting the SMC and neither seemed to do anything. My guess is it's defective, so I'm probably looking at a trip to our nearby Apple Store... the only thing is, I don't want to be without my computer for an extended period of time, since I use it for work and everything.
Is this the sort of thing that the Apple Store could order the new part and do the swap in house? If they replace the whole unit, could I put the existing HD in it? (of course the defect shows up right after I migrate and do all my upgrades, installs and patches)

I recently just had the LCD on my 24" imac replaced due to a stuck pixel. Without even bringing my imac into the apple store i told one of the genius bar associates about my problem and they ordered the LCD without even seeing my computer. They then called me when it came in and i took it down there for it to be replaced. I took it on a monday morning and i went and picked it up on tuesday. It is an in house repair so as long as they are not super busy you should not have to be without it for to long. I would try what i did, go in their without your imac first and tell them your issue and see if they will order the part. That way your not leaving your imac there while they order the part in.
