Images pixel

Hi there!!
I have a little problem with this test website here: http://muguet.desniklik.com/
as you can see the progression numbers below the slider are a bit funny, as if some pixels from the outline of the numbers were missing...
try open the same page with IE of Chrome, it's perfect.
What could this be?
thank you!

Hello ,
You want to compare these two image to find what ? In other word in case program find something what event you want to happen ?

Images pixelated in Aperture, not iPhoto?

I have been importing all my images to Aperture from an external drive, and all is going well. My problems is some of my images are pixelated when viewing them in Aperture. When I open iPhoto though and view my Aperture library in iPhoto the images look normal. I have not imported them to iPhoto, I am just curious what is going on here? I am an Aperture beginner so I am lost as to why this is happening? Hope that make sense. It is kind of hard to explain what is happening.
Thanks for any help in advance,
Christopher

Re: Images pixelated in Aperture, not iPhoto.
I am having a similar problem but instead of iPhoto, its Bridge. The same exact photo that I opened in
Aperture at 100% is quite pixelated yet when opened in Bridge, it is not. I am using Aperture 3.2.2, on a
MacPro 2x3 GHz Dual-Core Intel Xeon w/ 9GB Ram, running 10.6.8. I thought it might have something to
do with the graphics card. I have the ATI Radeon X1900 XT. When I copied the same raw file to my 13" Mac
BookPro with a NVIDI GeForce 9400M Graphics card, the photo looked fine in Aperture. Since Aperture is so graphics card intensive, is it possible that it needs a better graphics card? If so, is there a better one I could install in my MacPro?
Thanks for any help.

What Is The Best Image Pixel Dimensions For iPad 2 Photographs?

I just purchased an iPad 2 64Gb. I want to add photographs to my iPad. I want the photographs to completely fill the screen but still be small enough to use the minimum amount of memory space. A smaller image size will also make them more responsive when navigating between images.
Does anyone know the image pixel dimensions that I should use to have the photographs completely fill the iPad screen? I am assuming a resolution of 72 pixels per inch is sufficient because the screen is essentially a video screen.
Thanks!
Bill

1024-by-768 is the size of the screen.

High image pixel depth

I would like to acquire and save a colour image with the highest pixel depth possible using IMAQ for IEEE 1394. The resolution does not need to be high (640x480 at most) and the frame rate can be very low (1-3 Hz). Is it possible to get very high depth in an image when the majority of LabVIEW functions (i.e. write images, avi) use 8-bits/colour? I know that in the IMAQ array to colour image function there is a U64 output that is used if supported. Does this mean that I can get 16-bit depth per colour and if so does anyone know a camera that would support this?

Hi Ghost,
Like you said at the end of your post, the ability to record an image with such pixel depth will depend entirely upon the camera being used. Assuming you have a camera of this bit depth, it is certainly possible to use LabVIEW and IMAQ 1394 to interact with that image. The write file functions you mentioned are bound by the format of the file type you are trying to save. For example, an avi file supports only 8 bit images. If you wanted to save an image to file with greater bit depth, you can use IMAQ Vision to save one of these images as a .png or .tif file.
Let me know if you have any more questions!

Robert

Images pixelated in iDVD main screen

hi all,
i create an annual dvd with slideshows and videos. this is my 8th one and i've never had this problem before!
i'm using the idvd them "portfolio". when i first started populated the drop zones, everything was fine. the photos i'm using are hi-res and looked great. a few hours into making the video and SOME photos in the drops zones are all blurry and pixelated. i try dropping the photos in again, quitting, restarting, all that good stuff. nothing helped. i then re-exported the photos and put them in a different folder and dropped them into the drop zones. that worked and the photos were back to normal. until i left the main menu screen and some photos became pixelated again. what gives?! it's driving me crazy. i had it perfect and then as soon as i went to burn the dvd, the photos looked bad again.
here are screen shots of when it looks good and then when it doesn't.

It could just be the screen rendering of the images. Make a disk image of the project and play it with DVD Player. Check the images again and see if they are clear or blurred.
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

Still image pixel aspect ratio wrong in exported video (but correct in Premiere renders)

I've saved a targa still image from my footage and added it to the bin. It's properties show as follows:
Image Size: 1440 x 1080
Pixel Aspect Ratio: 1.3333
This correctly matches my sequence settings as I'm working with 1080p widescreen footage.
The image appears as expected in the Program window both before and after rendering previews. However, once I export my sequence as a video file, the still image is squashed (displaying incorrectly):
A work around would be to stretch out the still to a width of 1920 in Premiere so that the export displays it back at its normal aspect ratio - which works - but I don't understand why I should have to do this.
The other solution I found was to go to the bin and 'Modify > Interpret Footage' and although "Use Pixel Aspect Ratio from File" already shows the correct settings, to actively reset it (to the same pixel aspect ratio) with the 'Conform to' option:
This works too.
Surely a bug?
(using Premiere Pro CC)

Thanks for the quick reply. But then why does the still's properties (in my bin) show the pixel aspect ratio as 1.3333 (not square pixels, 1.0) and should it not appear incorrectly in both the preview renders and the exported video ? This seems inconsitent to me.

Exporting as Dreamweaver - Images pixelated

I produced a 300+ page product catalog in InDesign. I needed an easy way to export all the high res .EPS images from the catalog to be able to put them on our website. I used the Export as XHTML/Dreamweaver option to get all the .EPS images converted into .JPG's. For some reason however, about 70% of the images converted to .JPG's appear very pixelated or at "screen quality". They are nearly unrecognizable. I have adjusted the settings in the Export options and it doesn't seem to make a difference. If anyone can give me some direction or maybe an easier way of exporting all the images out - that would be great.

Dont know what camera was used, the footage was given to me. The dimensions of the footage is 720X486. Dont know if that helps.

Green images pixelated with black when opening in CS6

Hi there,
I have just come across a puzzling problem.
I am editig some images of furniture I have taken. All images are OK apart from green ones? When I open them in PS CS6 they are havily pixelated on screen with black. When I save the image for web, the preview that opens up, then image is fine again. It seems to be just an on screen, in PS problem.
Any idea how to solve this, it's very annoying!
Thanks,
John

It's AMD that have been doing the tweaking/correcting. Catalyst 13.1 can be problematic for any version of Ps that uses OpenGL although you may not have exposed the problems until yesterday. Your example image shows the bug where a pixel with red component of zero is displayed as completely black.

Gif images, pixels and hex colors

I'm not a java developer, though I at least have attempted to learn it. This may be a strange place to ask this question but java keeps coming up in my search so what the heck!
I am a highschool biology teacher-to-be and I am trying to design a lesson about DNA transcription and translation. I want the students to play a game where they take hex color codes (codons) and place a color card (amino acid) the hex code represents so that they build a big pixelated picture (the protein). I don't want to do the work of writing down the hex code for each and every pixel of the image, and was hoping there was some way to reveal as a list the hex color of each pixel in some sort of ordered fashion. I tried just dragging a gif file into a text program, but that didn't do it, ha!
Any ideas?
Thanks

Why are my images pixelated in Bridge?

When I'm in Bridge, some of my images look fine, others are pixelated. When I open the pixelated images in Camera Raw or Photoshop they are perfect. What gives?

What sort of images are these? It might be a good idea to try both of the suggestions at the top of the forum page:

I want to zoom into digital image pixels.

To demonstrate DSLR chip behavior at high magnification, I want to zoom into the frame and see how individual pixels actually look.
But when I use the Scale tool to enlarge the picture, FCPX thinks I want to avoid seeing pixels so it mushes the image, blurring all the pixels.
How do I get it to stop doing that? Can it be done in Motion?
Photoshop scaling has all these Bicubic options, but it also has the Nearest Neighbor option so I can see individual pixels in the blow up, there. Is there a way to get FCPX to do the same idea?

again: the actual compression (from any cam!) doesn't deliver single pixels.
it starts on the sensor of the cam - ever heard of the Bayer Filter?
http://en.wikipedia.org/wiki/Bayer_filter
if you could read out the raw data of that chip, you'd notice twice as much green 'dots' than red and blue, oops!
next, your cam compresses '4:2:0'
http://en.wikipedia.org/wiki/4:2:0
that Chroma Subsampling drops 7 of every 8 'color dots' ... most pixels are 'grey'!
finally, it's a lossy codec, working with 'assumptions'
http://en.wikipedia.org/wiki/Inter_frame
picture-prediction .... that's bits, not atoms
on de-coding, final delivery, these 'formulas' are calculated to a 1920x1080 picture ... but that is not the 'pixel reality' from your cam, nor on its sensor, nor in the file.
so, a zoom-to-pixel-level is a special effect, as mentioned above, create a close-up in Photoshop, showing r/g/b- squares … but this is not reality.

Load image pixels in 2D array - Duke Dollars up for grabs :)

Hi everyone!
I am writting a program that will work from a 2 dimensional array to get the location of any pixel (x and y) coordinates and it's color in an int format. I must apologise for my request but I do not have the slightest clue about images and all I know is how to load one and then display it. Can somebody provide the source code for representing an 50x50pixel .gif image in a 2D array with the index of the array being (x coordinates and y coordinates) and holding the color in int format and I will be eternally greatefull.:)
Your humble servant,

Thanks for the code but the functionality i need is
setting the array to contain all the pixels of my
image.
Can you please tell me how I can do that?!
Image imge;
imge=getToolkit().getImage("icon.gif");The way i will do:
Create a buffered Image 50*50
get the graphics for this image
draw your image into the buffered Image
use getRGB(x,y) to get the pixel
Image imge;
BufferedImage bi;
Graphics gi;
Color[] col = new Color[2500];
imge=getToolkit().getImage("icon.gif");
bi = new BufferedImage(50,50,BufferedImage.TYPE_3BYTE_BGR);
gi = bi.getGraphics();
gi.drawImage(imge,0,0,null);
for (int x = 0; x < 50; x++)
 for (int y = 0; y < 50; y++)
 col[x*50+y] = bi.getRGB(x,y));
[/code

Restrict image pixel size in multiple image upload

Re: Multiple Image Upload behaviour.
One of the only issues I have with this extension is if users try to upload an image within the limits I set (of 250Kb) but with a high pixel count.
For example, a jpg of 800 x 600 at 200Kb causes no problem, but a one of 2000 pixels at 150Kb probably will.
I understand that there is probably more server load to resize a large pixel image, so is there a way to check the pixel size of images to be uploaded as well as the file size and reject it if it is too large?

But what you could do, is retrieving the php.ini´s "post_max_size" value and display a note to your site visitors:
 
 
1. put this into the doc´s head:
 
 <?php $replace_max_size_MB = str_replace("M"," MB",ini_get('post_max_size')); ?>
 
 
2. the related message:
 
 Pics larger than <?php echo $replace_max_size_MB; ?> will be rejected by the server

Images pixelated/distorted in ADE

I just downloaded ADE, and everything seems to be working, except that the images are all distorted. You can actually see part of the images below the distortion, but the distortion consists of what appear to be pixelated, thick horizontal lines of varying colors that block out major portions of the image and make them unusable.
Has anyone else encountered this issue? If so, was anyone able to successfully resolve it?
Thanks.
Just realized that I can insert images, so here's an example:

Read this FAQ:
Donald Gruener, "3.1 - Importing and Placing Graphics into PageMaker" #1, 17 May 2002 8:11 am
TIFF is the preferred raster format.
EPS should be OK with a postscript printer (e.g. PDF), but PM's preview is poor.
PM7 will accept AI, but only up to Ver 8
John Davies, "3.11 - Importing Adobe Illustrator Files (*.AI) and how they differ from *.EPS" #1, 7 Dec 2003 7:46 am
Remember PM is archaic. Your client should be using InDesign by now.

Internet Images Pixelated

Recently I have noticed that when I open Firefox or Safari the images that upload/download are under severe compression and appear severely pixelated. For instance, when I open a compressed JPG on my Macbook Pro the image appears rather clear and unpixelated but when I upload that image to a site and then view it through Firefox and Safari it appears *very pixelated*.
It also occurs with images that are not mine and I am simply viewing on a site. This was not happening before!!
I cleared my browsers cache to see if that was a problem and so far, it has not fixed it.
Anybody got any ideas as to what I can do to revert it back to the way it was?

Yes, I see the big ugly squares. They are what appears whenever extremely heavy JPEG compression is applied to a low-resolution image tht has relatively large areas of similar colors. Something somewhere is applying such compression to the pages, or portions of them, that you are viewing in your browser(s). Your MBP is not doing that: it can't. Either the page images (or parts of them) are being compressed by the website owners or, if every web page is affected, they are being compressed by your ISP in the process of being transmitted to you, as Gordito suggests. That would greatly increase the speed of page loading, but at the expense of image quality. You wouldn't see the image degradation on an iPhone or cell phone — the screen is too small — but on the MBP's high-resolution display it would be much more apparent, IF the MBP were receiving the signal in the same highly compressed form as the phone. If the MBP receives the same web pages through an ISP that doesn't over-compress them, they'll look the way they ought to look. So if you are receiving these web pages through a cellular ISP rather than through a broadband connection, take the MBP to a wifi hotspot and connect through wifi instead. I bet things will look different then.
Compressing images is something a web browser can't do: a browser just displays the signal that comes to it.
