Particles "white pixel" Bug

I discovered that when using Particle Playground, with the particle type set to faded sphere, and the color of the particle set in the purple/violet hue range, that a ring of white pixels dust appears around the circumference of each particle. If I change the particle color to green or orange or something outside the violet range, the artifact vanishes.
This is in CS3, and it appears during both preview and render to RAM.

The pure white pixels are abruptly-gone when the hue is rotated away from the violet range, so I don't think it's an HDR issue. Also, I noticed on the larger particles passing closer to the 'camera' that the white pixels form a complete circle, which gets cropped off as the 'bubble' (what the white pixel outline looks like) passes about 1/4 of the preview window width to the right. The left 1/4 of the window shows this artifact--the rest does not. I also confirmed that this does not show up on rendered images.

Bright White Pixel

My iPhone 6 has got a bright white pixel that can be seen on any colour exept black. You can even see it on dark grey. I am wondering what this is, and how I can fix it. It is unlikely it was due to pressure. About the size of a grain of salt or two. Tiny but it bugs me so much. Please help. Thanks

Bright White Pixel on LCD - But NOT Visible on Black Background

Hi All,
Just noticed today on my macbook pro (Early 08 - july manufacture) that a small white spot has appeared. Not the blobby large spots that were common lcd problems before on older models, but almost a pinprick of a white spot.
Now its not a dead pixel, since its not black, and its not a stuck pixel, since it has no definite visible colour, also, it is NOT visible on a black background (is this due to the way LED backlights work???) so i dont think its a HOT pixel exactly...it is most visible on plain white backgound - but on any colour R/B/G it is visible as a spot that is brighter than the other area around.
...so...what is it, how can i find out what it is? and might warranty help (presumably for one pixel = no)?
What might i try? Anyone else have experience of this? Every other forum post forum either talks about: 1) dead pixel that si ALWAYS black 2) Pixel that is always white but even on black background 3) coloured pixel - none of which i have exactly, my white pixel is NOT at all visible on black background.

Hi:
I just want to tell you that my Macbook Pro is the same as yours, at it presents that small white spots problem.
In fact, let me tell you all, that those are not dead or stuck pixels, is a problem on the LCD itself, the pixels on that spots are lighter than the other pixels, that's why they look white, but they are not white. They are a lighter color than the other pixels. But again, those are not pixels, in fact they are a group of pixels, from 6 to 13 pixels eash one. Also you can notice like hairlines with the same issue.
My white spots are on the left side of the screen, y 4 of them.
Also, my screen haves particles inside.
I will take my laptop to the apple service senter, and it doesn't matter what they say, they will have to exchange my screen.

White pixel band on my 15" screen

Hello guys!
I hope you can help me because I do not know where to turn now. Let me explain my problem.
I purchased in the month of November 2010 my 15 "MacBook Pro (mid 2010, 2.4 GHz, 4GB of RAM). During the first year of use no problem, the mac worked great and I used it immediately as your primary computer ( traveling and living away from home was an obvious choice.) If at the beginning of the second year were presented serious problems, namely: continuous computer crash, that I initially tried to solve disassembling and exchanging of cards instead of the Ram ), irreversible damage to hard disk drives (internal and external) resulting in loss of critical data, partly recovered by programs such as Drive Genius. And a band of white pixels appeared on the screen (approximately 6.5 cm from the left side of the screen wide and about 4 cm), which is attenuated slightly shake up the screen. All these problems (in time of exams and work) have led me first to ask for help Aesse computer, Apple Premium Reseller of Catania, with whom we have tested the Mac for more than a month, and it was found necessary to replace the Main Board. same fate at the Apple Store in Catania.
After litigation related to Apple's warranty (the problem occurred in the second year and was linked to a lack of conformity), the Mac has been sent by the retailer Euronics (chain reseller Italian electronics) where I bought it, to its headquarters in Turin , where it replaced the Main Board. It's all right for a year.
To be noted that in terms of performance, the Mac is back to the first, but about two weeks the band reappeared pixels, giving me a few problems in the visualization and realization of the work (I'm a graphic designer). The Hardware Test does not detect any problems and the band alternates between moments of everlasting presence in moments of terrifying absence (for example, two days ago I had to present to a client a job with the **** white band, the first five minutes when he was absent ).
I did research on research on the internet but it seems this problem is far from common (the only loser I am, of course). I assume by contradiction that it is a burnt connector on the screen, because when the screen is slightly bent at the sides of the band fades or disappears (sometimes to reappear, sometimes to disappear), but would not explain why after repair (not touching the screen, but only the Main Board), the problem was not resubmitted immediately, but only after a year ... So, not being an expert, I ask you if you can understand what the problem is, because I have run out of options.
Thank you all for your attention

My refurbished rMBP 15" has a stuck (white) pixel and is still under the 1 year limited warranty, can/will Apple repair it if I go to an Apple Store?

Hi, my refurbished rMBP 15" has a stuck (white) pixel and is still under the 1 year limited warranty, can/will Apple repair it if I go to an Apple Store?
I just discovered today that my MacBook has a "stuck" pixel. I read that the display has to have at least 5 dead/stuck pixels else Apple is not going to repair it, is it true? My warranty expires in 1 month so I can't really wait for 4 more pixels to die or get stuck.
Temporary fix:
I know that this is something I can't really repair myself, but I tried some things such as changing the display resolution to it's "Full" 2880x1800 resolution and It actually reduced the size of the stuck pixel.
Thank You,

MacMini white Pixels

Hallo everyone,
I am having a problem with my Mac Mini. When I start it up normally I have a lot of white pixels on my display. When I start it up in Safe Boot everything is normal.
I already changed the RAM, installed OS Tiger new, reseted the smc. Nothing helped.
I would be really thankful for your help.

I'm sorry, you are not answering my question. The load screen of MacOS starts when the grey Apple logo appears on the grey screen, and ends at the login screen, during which the system is doing a lot of different things.
Do these visible defects first occur when:
-the system has chimed but the screen remains black,
-the grey screen first appears but is blank,
-when the grey screen is on and the spinning cog appears,
-when the screen turns blue but is otherwise blank
-when the first white box appears during the blue screen,
-when the white box has begun to report MacOS loading with the progress bar showing
-when the MacOS load has completed and the login dialog appears (or the system is auto-logging in if set to do so,
-when the desktop first appears but is largely blank,
-when the desktop is being populated with icons but the menu bar is either not yet present or blank,
-when the desktop is complete and the Finder has fully loaded.
Or does it change from startup to startup? I'm not trying to be awkward or pedantic, just trying to find out at what point you see this happen because that'll tell us a lot about the possible cause.

Mac mini 2011 White Pixels and Resolution Off

I just replaced my 2010 mac mini with the 2.5 ghz 2011 version and I noticed my resolution has been shifted up about 8 pixels and I see lots of white pixel glittering. The glittering and image shift disappears when I change the resolution to 1080i instead of 1080p. I have the same HDMI connection as I had before connected to my Westinghouse HDTV. How can I fix this?

Just a thought. I had audio noise problems on my mini. Went thru two mini's and two speaker systems till I figured out it was power line noise. Got a filtered power strip - noise gone.

White pixel on Macbook Pro 13" Retina

I have a white pixel on my screen. Do I need to take it in or is there an easier way to fix it?

Called a "stuck" pixel. If there are enough, may be cause for screen replacement under warranty. Stuck-on-black are generally considered more severe than stuck on any other color, especially white, cause they can be confused for a decimal point, etc. Each brand has its own rules as to how many and where are needed to justify replacement.
Urban lore has it that these pixels can be "repaired" by rubbing on them, with care not to crack the glass or to cause more pixels to join the fun. Search around if you want to try something before taking it in.

When using 'sponge' effect on a fill, how do I get rid of the white 'pixellations' (if that is what they are called around the edges of the fill?

When using 'sponge' effect on a fill, how do I get rid of the white 'pixellations' (if that is what they are called around the edges of the fill?

I tried to give you this solution before, but maybe you missed it. This simple procedure will mask out all the various sponge edge-artifacts. Here it is in simple steps:
1. Make the path shape you want to apply the sponge effect to.
2. Highlight that path, and select Object > Path > Offset path ... choose +2 points (or whatever works for your drawing scale, to ultimately eliminate the outside line and the artifacts) -- this will make a slightly larger shape, based on the original shape.
3. Cut the outside path (command or alt-X), select the inside path, and paste the outer path BEHIND the inner path (command or alt-B).
4. Apply the sponge effect to the OUTER path.
5. Highlight BOTH paths, and create a MASK (command or alt-7).
Now you have your original shape, with sponge applied, and the outer 2 points (or whatever your Offset Path was set to), are masked out, masking out the outside line and the sponge artifacts.
This works with any Document Raster Effect Settings dpi.

White pixels on my pics when i post to iweb...

I am a photographer and use iWeb for my main website. Lately I have been noticing little white pixels on some of my pics! It doesn't show up on my computer (my mac), but it does show up on my home pc. I have asked friends to look at my site for me to see if the pixels show up for them. The friends that have a pc saw the pixels and the ones with a mac did not! How strange!
If anyone knows how to fix this problem...I would greatly appreciate it!!

(go to proofs, then jack, then scroll down towards the bottom and click on 22b) (**oh...and this only happens to color pics!)

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:

Is it possible to tell me how i can make program in labview that take pixels of black and withe image and give coordinate of black or white pixels back to me.

hello everybody
is it possible to tell me how i can make program in labview that take pixels of black and withe image and give coordinate of black or white pixels back to me.
Solved!
Go to Solution.

Here's a slightly simpler version.
(Depending how you want to process the output, you might not need to traspose and/or reverse. Boolean to 0,1 works directly on the 2D array if needed )

it is good. i could enter 1bit image in and show it in array. now i want to take pixels coordinates. i meen i want to have (x,y) of each pixel to send it pixel coordinate to another program i wrote for steppers motor.
Can you be a bit more specific on how the output is supposed to look like? Initially you wrote "black or white", and since all pixels are either black or white, do you want to send all pixels? In what format? In what order? Please clarify?

White pixels in animated GIFs with transparency

Problem: at least one transparent pixel becomes solid white when exported as a GIF
Details: there is approximately one pixel per layer, but occasionally there are more. There doesn't seem to be a pattern in where the pixel(s) are located. How can I prevent this from happening? If I can't, what's a good way to get rid of the pixels later?
I use Photoshop CS3, but I think this problem may not be related to the version I'm using. Sorry if this problem has been resolved in a later version!

The pixel is there. That's why it's showing.
What Marion was trying to explain is, you may not have seen it before trying to save as GIF. If a pixel exists which is 5% white, you really won't see it against the transparency checkerboard. When you save for web, the application can't make a 5% opaque pixel for a gif. It's either 100% opaque or 100% transparent. Since the Save For Web sees color there.. it assumes you want that pixel and chooses 100% opaque.
The solution is to find the partially transparent pixels and remove them before choosing save for web. Often adding a temporary solid-color layer below the artwork will help you see these partially opaque pixels, as will adding a temporary stroke layer style.
For example this image would appear to be transparent except the two circles (horribly blurred due to size increase to for this example).
But if I were to use Save for web, all sorts of things would appear. Look what happens when I put a temporary layer style stroke on the layer.....
All the white pixels which were not visible suddenly become visible. In fact, download the first image and add a layer style stroke to it yourself. You'll see how nearly transparent pixles can effect an image.

White pixels and too much contrast on new touch

hi all!
i got a new touch today. i allready have one but this one i won in a contest. anyway, when after having synced over alot of content i started noticing som strange things about the screen. first of all, some colors looks washed out and too bright. it has nothing to do with the settings since i allways had my old one on full brightness and it never looked like this.
then i when i looked closer at the screen i saw alot of white pixels that disapeared and apeared depending on how i hold the touch. here is a pic of the pixels (note that the screen is not this bright, my cam just made it like that for some reason):
http://img182.imageshack.us/img182/8443/shiiiit012copyqv1.png
so is this what people call dead pixels? would i get a new touch if i send it to apple you think? or are there anything els i could do? we dont have any official apple stores where i live. thanks alot in advance!

Did you get this problem fixed? I have only had my ipod touch for about 30 days and it too lost it's contrast. It now looks white washed, with little contrast. There is no true black, white or gray, and the colors seemed washed out. I am considering simply taking it in for repair. What did you do? Thanks for any information you can provide.
