DESPERATE Image compression help needed!
Hi,
im doing image compression techniques for my final year project and desperatly need some code written in java to compress a image file using the huffman code. im using the BufferedImage class to store the image (jpeg) and need a a bit more code to do the huffman coding! i have tried most places on the net, but all they do is describe what it is! not how it is implemented!
Thanks!
If you are talking about just huffman coding, then it is pretty easy. However, if you are talking about writing a JPEG compression algorithm, it's not so easy. You have to take into consideration the sampling of Y to Cr and Cb, the quantization values, the huffman tables, headers, # of components, etc...

The last two links provide implementations. I think the last link is probably the simplest
implementation I've ever seen for JPEG. It works, but it's not great :)

Site linked on facebook has no thumbnail image - Admin. help needed
hi, after looking thru the forum i've found 3 different posts asking how to make links posted on facebook come up with an appropriate thumbnail image, but none of them have an answer. Is it possible for a site built with iweb to do this, and if so, please tell us how. Thanks
The only solution is to write a piece of code into the header of the page and that will tell facebook where to pull the title, description and the photo from. The code that needs to be inserted is below.
THE PROBLEM - this solution doesn't work if you have built your site using iweb. Everyone that has iweb has responded to the solution (everywhere this is written about) has said this.
Does anyone know another work around?
The solution for anyone without iweb:
<meta name="title" content="INSERT CONTENT HERE" />
<meta name="description" content="INSERT CONTENT HERE" />
<link rel="image_src" href="INSERT LOCATION OF PHOTO WEB ADDRESS HERE" /> -
Please help - image viewer help needed
hi
can anyone plase help
I am building a CSS site and want a simple image viewer -
just one image viewing in a box with >> and << buttons
for the user to scroll through images. I know that dreamweaver has
a built in Image viewer but it does not work properly. It will not
go back to the first image after it has gone forward to the next
images. Even the tutorial does this.
Does anyone know why this happens or can anyone direct me to
a good tutorial that will provide instructions for this?
I know that there are many add ons to deal with this but it
is only a small function that I should be able to produce myself.
Many ThanksIf you're building a CSS site you might not want to use
Flash. Try Googling
for "lightbox". If you have a development budget, you might
also want to
have a look at this:

Hi people, first time posting, spent a while researching nobody seems to have covered this as far as i looked. I am dealing with about 1200 images in flash, in sequence, i tried importing the frames all at once and they all came up blank... for some reason they were red up until 315 and then the rest were blank, some were black. People have said that it is likely a ram issue? what the hell? the images total just under a half a gig and i have 8gb of ram, i looked at my processes and flash is only using about 3gb of ram. I tried importing about 100 images at a time, and i got to about 300 and again, the same issue started, after seeing them all work up to 300. I need to be able to take out a frame here or there from a video. I hope i need not exaplin more, the point is i need this image sequence to work, and i need to be able to see all 1200 frames and it simply is not working for me. Any solutions? flash has been driving me nuts lately.
This is a known limitation in Flash. Do note that the size of the image on the filesystem may say something like half a gig but once you take it into Photoshop you'll see the uncompressed actual size of the image (on the bottom of each window). For example a 52KB JPEG in Photoshop right now states it's 950.2K. I'm assuming your images are probably larger so you can quickly see how this becomes an issue. Open 700 52kb images and you're sitting at 7GB ram, 1GB for the OS and are now in pagefile (HD ram).
Flash is about being light weight. After Effects would sequence those images like nothing but Flash is not designed like that.
The solution depends on your needs. Why are you importing 1200 frames individually? If the frames make up a video (or several videos) you should create them in an actual video while saving huge amounts of disk space and processor, while also getting around this Flash limitation. -
Hi
i am trying to select my inline graphic after it is added to textflow.
using filerefrence once image is loaded and following funcion is to handle this
function imageLoadComplete(e:Event):void {
imgLdr.contentLoaderInfo.removeEventListener(Event.COMPLETE,imageLoadComplete);
var mc:MovieClip = new MovieClip();
mc.addChild(imgLdr.content);
mc.addEventListener(MouseEvent.CLICK,imageClicked);
EditManager(textFlow.interactionManager).insertInlineGraphic(mc,100,100);
textFlow.flowComposer.updateAllContainers();
when i click on image event is called. after click i passed this image to resize handler and here is to resize this. but it handles image only if cursor is at side of the image or image is selected in a way that it is highlighted. other wise modifyinlinegraphic is not working for me if i pass my movieclip refrence.
Please help i have spen more than 10 hrs to figure out this problem
ThanksI think most likely the problem is that you are not passing an explicit operationState. That is the last parameter in EditManager.modifyInlineGraphic, and if it is left out, then TLF will use the current selection as the location of the inline graphic. If you want to modify an inline graphic at a particular location, you should create a SelectionState at that location, and pass that as the operationState.
Suppose the inline is the first thing in the TextFlow. Then you could do this as follows:
var selectionState:SelectionState = new SelectionState(textFlow, 0, 0);
IEditManager(textFlow.interactionManager).modifyInlineGraphic("source", 100, 100, null, selectionState);
Then it should find the inline graphic at the start of the TextFlow, regardless of where the current selection is.
If this does not sound like the problem you are having, please send a code snippet for the event listener where you call to modifyInlineGraphic.

Missing images error. help needed
Hey,
Since i had an issue with having iPhoto library on Airport, i moved it back and rebuilt library etc.
All is fine but there are about five photos that have been lost which is fine.
I dont mind the loss of these photos, but id like to get rid of these error messages.
Please see screenshot attached.
S"copy imported items to the iPhoto library" is checked.
It wasn't when these files were imported.
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. -
Help Needed..Fingerprint Identification..Image Manipulation
Norfolk State University Student (Help Needed):
I'm working on Fingerprint Identification using image correlation and/or a feature-based approach. First, Goal is to minimize the lines of the minutia so that they are one pixel thick. What services does Labview offer that will help me accomplish this task??Hey Snakehead...,
Have you tried improving your original image with better lighting, better camera, better lens, etc.? What image processing have you done already, or are you starting from scratch? I agree with AnalogKid in providing some sample images to the forum so we can get an idea of what you are working with. Have you performed any morphology processing on the image? Have you tried edge detection functions? There are numerous functions that NI provides with their NI Vision software that will help you process your image, it is just finding the right combination that is the toughest part. Last, if you do have the Vision software, I might suggest taking a look at the Vision concepts manual to get an idea of the different functions and their capabilities. Let us know what kind of images you are working with and what you have done so far, and last, what you would like to eventually see. Thanks, and have a great day.

I would like to remove a short gray edge from two images. I need help in that I am not yet able to use PhotoShop. Could somebody kindly help me with this?
I doubt it Doc Maik, but I am certainly happy to learn The image is this one (and a similar one). They would be beautiful portraits if not for the "extra mouth". The grey edge that I would like to remove is the excess of (grey) mouth that is actually my horse's chin, but that in the pictures looks like a wider, looping mouth. Practically, looking at the picture, the "extra mouth" to the left. What I would love it to be able correct that to look like a normal mouth, which means that half of the protruding edge should be removed. I am not sure I was able to explain myself, but here is one of the two pictures. I thank you for you kindness in being available to advise me.

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.

Iphone 6 photo image compression/ quality loss
iPhone 6 and 6 plus have pretty remarkable cameras. But oddly, Apple doesn't seem to want you to keep the high quality images and videos you take. As soon as you email let's say a 3.5 mb photo image, you are asked what size you want to email it in and given a series of compression options. Once you make the decision the first time, that decision is permanent. Apple does not really warn you that you are about to permanently, massively compress (destroy) that original image. There should be a better way to preserve original image files. The email compression decision should impact only that email -- not the master image file. But it does.
Also, if you take an amazing video on your iPhone 6, when you put that video in photostream or in the cloud or email it, there is no warning to you that you've just massively compressed the video. I took a video that was close to 10 mb, emailed it to myself to save it, then had to wipe my phone because of a problem. When i reinstalled and opened the video, it was about 10% of the size of the original video. Original gone. No warning.
It's sort of odd that Apple would not think to create better menus, options and communication/guidance around image compression.
Lastly, if you take a picture on your Iphone .. there is NO WAY to know any metadata on that image file -- unless you go to email it and you get that compressino option screen. You can't see anywhere else the image file size. Again, why make such a great camera if all you want is to massively degrade the image files the moment you do anything with them?Howdy elkspark,
If your camera photos still dont look quite right, I would recommend taking a look at this info from the following article to help determine what might be causing this to happen:
Get help with the camera on your iPhone, iPad, or iPod touch
Your photos are blurred or out of focus
If your photos are blurred, out of focus, or have dark spots, try these steps:
Make sure that the camera lens is clean. If you need to clean the lens, use a microfiber cloth. If you see dirt or debris inside the lens, take your device to an Apple Retail Store or Authorized Service Provider for more help.
Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
With iPhone 6 Plus, a metallic case or magnetic lens could interfere with optical image stabilization. If you have a metallic case or magnetic lens attachment, try taking a picture without it. Then compare the quality.
Adjust the focus by tapping on the person or object in the preview screen. You’ll see the screen pulse or briefly go in and out of focus as the camera adjusts. In photo mode, try to stay steady when adjusting the focus. If you move too far in any direction, the camera will automatically refocus to the center. In video mode, you can adjust the focus before you begin recording.
Thank you for using Apple Support Communities.

Best practices for image compression in dps
Hi! I have been reading up on best practices for image compression in dps, and I have read that the source assets of panoramas, image sequences, pan and zoom images, and audio skins are not resampled on upload. So you therefore need to resize them and compress them before dropping them into your article, because dps doesn't do it for you. Okay can do!
So then Im also reading that the source assets of slideshows, scrollable frames, and buttons ARE resampled as PNG images. Does this mean that DPS will compress them for you when you build the article? So does that mean I shouldn't bother going to the trouble of resizing these images at all? I can just pop in the 15mb 300dpi files used in the print magazine and dps will compress them upon building the article - and this will have no affect on file size?
And this is also the case with static background images?
Thanks for your help!All images are automatically resampled based on the size of the folio you make. You can drop in whatever resolution image you want, it doesn't matter.
