Huge MemoryAllocation - ColorMatrix on 3 - 4 MB images

Hi all
i am currently working on the medical project (built with Flex SDK3.3. and Flash Player 10.0), the project provides the drawing and image manuipulation feature on the (*.JPEG) photos, those JPEG photos are extracted from a medical DICOM format file (XRay, US, CT, etc...) with its size of every single jpeg is most likely around 3 - 4 MB (Dimension 3500 x 3000).
The problem i now encountered is the memory problem. When the 4MB image load completed, the application would occupy around 8x MB memory. However, the issue occur when i going to implement the ColorMatrix which changing the image Brightness, Contrast, etc .. the memory allocation of app. increased significantly (up to 18x MB) MB. As a WEB app., 18x MB is a BIG number and is the serious concern of performance
Hence, hope will get some help from all of you experts ....
or
any alternative way that would able to changing the Brightness, Contrast of the image but with better performance
or
any technical suggestions if i implement like that .. any risks !?
Please help ........ indeed .....
Attached please find the source code.

Efficiency of decoding and displaying image files?

BRIEF SUMMARY
My question is this: can Flash Player download JPG and GIF
files from a server and rapidly open/decode them, ready for
display, efficiently and
entirely 'in memory'?
Would Flex be a good choice of language for developing a RIA
that needs to continually download lots of JPG and GIF images
on-the-fly from the server and render them on the screen? I *don't*
want my application to thrash the hard disc.
BACKGROUND
I am designing a 'rich' web app, and I'm investigating
whether Flex is the right tool for the job.
Although Flash's animation features are an obvious selling
point for implementing my user interface, I also need to do some
server-side rendering. What I want to do is perhaps a little
unorthodox: I will be generating lots of GIF and JPG files on the
fly and these will be streamed to the client (along with other
application data, e.g. in XML format) to update different parts of
the on-screen document. In need this to happen very quickly (in
some cases, creating the effect of animation).
It happens that JPGs and 16-colour GIFs will be, by far, the
most efficient formats for streaming the images, because of the
nature of the application. I could of course send the images in
some proprietary format, geared for my application, but presumably
decoding the images would be slow as I would have to implement this
myself in ActionScript, and so I would be limited by the speed of
Flex 'bytecode'. (I realise Flash is a lot more optimised than it
once was, but I am hoping to see a gain from using image formats
that Flash natively understands!)
Naturally the internet bandwidth should (in principle) be the
bottleneck. However, assuming I can get my image files to the
client on time, want I want to know is:
how efficient is Flash at loading such files?
Bearing in mind that I'm not just displaying the occasional
image -- I will be doing this continuously. Most of the images
won't be huge, but there will be several separate images per
second.
The image files will be a mixture of normal colour JPGs and
4-bit colour GIFs (LZW-compressed). I know that Flash natively
supports these formats, but depending on how Adobe have implemented
their LZW/Huffman decoding and so on, and how much overhead there
is in opening/processing downloaded image files before they are
ready to 'blit' to the screen, I imagine this could be pretty fast
or pretty slow!
If my client only has a modest PC, I don't want the JPG/GIF
decoding alone to be thrashing his CPU (or indeed the disc) before
I've even got started on 'Flashy' vector stuff.
I'm new to Flash, so are there any 'gotchas' I need to know
about?
E.g. Would it be fair to assume Flash Player will do the
decoding of the downloaded image entirely 'in memory' without
trying to do anything clever like caching the file to disc, or
calling any libraries which might slow down the whole process? It
would be no good at all if the images were first written to the
client's hard disc before being ready to display, for example.
Further, if I'm doing something a little out-of-the-ordinary,
and there is no 'guarantee' that images will be loaded quickly,
what I'm doing might be a bad idea if a later version of Flash
Player may (for example) suddenly start doing some disc access in
the process of opening a newly downloaded image. So, while I could
just 'try it and see', what I really need is some assurance that
what I'm doing is sensible and is likely to carry on working in
future.
Finally, I imagine JPG/GIF decoding could be something that
would vary from platform to platform (e.g. for the sake of
argument, Flash Player for Windows could use a highly-optimised
library, but other versions could be very inefficient).
This could be the 'make or break' of my application, so all
advice is welcome! :) Thanks in advance.

You need a servlet/jsf component to render the image in the response.

Image Scaling Bug?

I've been working with flex for a few weeks now, and I've
come across this odd behavior in the Image class. The livedocs
state that the default value for the scaleContent property of an
Image object is 'true'. This is the case, and when setting the
width or height of my image it scales correctly. The problem is
that the container that holds the object only scales with the
explicitly set value and leaves the other as its original size.
The following code is a small testcase to show the behavior
in action.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Style>
.test {
cornerRadius: 0;
headerHeight: 0;
borderThickness: 1;
dropShadowEnabled: false;
borderStyle: solid;
backgroundColor: #333333;
borderColor: #ff0000;
titleStyleName: "myTitleStyle";
</mx:Style>
<mx:Box styleName="test">
<mx:Image source="glassdoor.jpg" height="32"/>
</mx:Box>
</mx:Application>
You'll have to replace the image name with one that you
provide, and set the height to something smaller that the image's
height to see the effect. The box's red border shows that it
realizes the image is 32 pixels in height, but doesn't seem to know
what to do with the implicitly scaled width. Any ideas? Am I doing
something wrong, or is this a bug? Since the box normally conforms
to the size of the object inside it, I would have expected it to
shrink on both parameters to continue hugging the outside of my
newly-scaled image.

The problem is that when the Box asks the Image for its size
it can only report the explicity set height. When the Image tag
loads its source it scales it to make the size you set (32 high)
but doesn't change its width - it is the Image and not the Box that
is causing what you see. The Image won't shrink to fit the image
loaded. Try adding horizontalAlign="center" to the Image and see if
the loaded source floats in the middle.
Using horizontalAlign and verticalAlign on the Image tag
aligns the actual image within the Image tag space. For example, if
you have <mx:Image width="100" height="100"
horizontalAlign="center" verticalAlign="middle" /> and you load
in a 300x600 image, the image will be scaled to 50x100 and be
centered within the 100x100 area of the Image tag.
In general, if you cannot give an explicit size, give a
minWidth or minHeight, so the measurement phase of the Flex
component layout cycle has something to work with.

Interface Builder refuses to see "@2x" image files

I'm making some apps with support for all three major iOS platforms: iPhone&Co, iPhone4 and iPad. This support means, naturally, having larger-resolution images for the latter two platforms. Currently I'm making the apps universal, so the same app will run in all of them.
Since most of the double-resolution images of the iPhone4 version of the app can be used as-is in the iPad version (only things like background images have to be made separately for all three types of platform due to differing screen resolutions; the rest can be done with simply laying out the elements appropriately in the iPad as compared to the iPhone4, using the same element images for both), it would be a huge waste of space to make separate images for the iPhone4 and the iPad, when these images would be completely identical. Thus it only makes sense to reuse the same "@2x" images of the iPhone4 on the iPad version of the app.
This worked nicely for a while. However, at some point quite suddenly (I don't really know what happened), Interface Builder started to completely refuse to see any image files with a "@2x" in their name. It won't show them on the drop-down menu where you select an image (eg. for an UIImageView or UIButton), and if you write it manually, it will refuse to show it (only showing the question mark image symbolizing a missing image file). The image will show ok when running the app, but IB simply refuses to acknowledge the existence of such images. If I rename the image such that I remove the "@2x", then IB will accept it, but not if it has those characters.
As said, IB did see the "@2x" images at some point, but for some reason now it doesn't. (This is a bit of a mystery because I don't remember this happening after any kind of SDK upgrade or anything.)
This tells me that this is either 1) a bug in IB, or 2) intentional behavior, and the "@2x" images should not be "abused" in this way to create an iPad version of the app properly.
If hypothesis 2 is correct, then what is the proper way of using the same images in both the iPhone4 and iPad versions of the app? Duplicating the image files would be an enormous waste of space (the apps are quite graphics-heavy).
One "kludge" that comes to mind would be to create soft links for the images so that the iPad versions of the image files would just be soft links to the @2x iPhone4 images. However, I don't know if the bundling mechanism of the iPhone SDK supports soft links, or if it will simply make copies of the images (in which case each such image will end up being stored twice in the bundle).

I guess I don't understand why you want a solution when you've found one already.
Just use ".2x" or "-2x" or whatever.
Report the bug, use your workaround and move on.

Exporting as PDF makes huge colour change. Please Help.

I am really hoping someone can help me here. I have an image which has been created in a CMYK document, when I export it as a PNG the colours look perfect, however when I save the file as a PDF the colours also look ok in Adobe Reader. When I email the PDF to my phone for example or to another person on a different computer the colour shift is huge as you can see here:
The image on the left is how it should be, I am not the only person who uses this MAC so I think somewhere some settings have been changed and I cant figure it out. I am at a real loss as to what I can try to resolve this. I appreciate any help that you can give me.

I wouldn't expect a mobile screen to display CMYK values accurately or the same as they display in Adobe Reader on your computer.
How did you create the image on the right? What PDF settings did you use when saving as PDF? What app are you using to view the PDF on the mobile device? How about on the other computer? Are both computers' displays calibrated/profiled?
Generally, for PDFs intended to be viewed on a variety of displays, I'd recommend converting to sRGB when saving the PDF.

Exporting Clipped images for the Web... CONFUSED! ? Help ..? AI CS3

Hi folks,
I don't use Illustrator as much as I'd like, since my workflow is mostly on
the web, but I'm finding it nearly impossible to export images I receive
from print designers for web use. Many of these images are EPS or AI.
They are clipped images, which is great, BUT when I try to Save for the Web,
the error comes back that they are too large for the web and may crash AI.
OR if I export to PNG or PSD, the files lose their transparency and I have
to extract them manually from the white backgrounds, which defeats the whole
purpose. I have tried opening in Fireworks and Photoshop with the same
result. I've changed the originals from CMYK to RGB, but it doesn't help.
Plus the images export with a huge crop area instead of just the image
itself.
I'd really like to be able to use AI, but I'm finding this situation
unworkable. I am sure I'm missing something simple , but I'd appreciate any
help greatly!
Thanks
Jeff

Thanks for your help Jean et al.
I only use Illustrator occasionally and when I have to. Not because I don't
like the idea, but I'm almost completely web oriented and I find its layout
is not as instinctive and smooth as Fireworks, and I use Photoshop for
original layered images. The problem comes when I get a file from a printer
who uses Quark and knows nothing about web prep and exporting for other
uses. He couldn't export a layered file for some reason even though he had
the backgrounds layered for print work.
You are right, I've opened the tiff and eps docs from the printer before and
played with them in AI, and saved them to ai native formats. I *thought* the
eps files were created in ai by the printer, because they had the clipping
paths and artboards. Obviously they were not. They had just opened with the
default 14400 artboard which is why I thought they had been "set." So when I
set the new 30x30 custom, I started seeing these files with a new
artboard...
So, in sum, I first tried to use these files in Photoshop, but they open
as flat files and the clipping paths are lost. Only by experimenting with
ai, did I find the files had clipping paths. I guess what threw me was that
ai could extract clipping paths from eps that Photoshop could not.

Virtual Streaming images

Hello,
I'm fairly new to Java. I first started with applets, and just recently learned just a little bit about servlets to help supplement my applet I have been created.
This applet takes input from the user, such as date and time. And with this input, it starts cycling through JPG images. The user can pause, stop, play, etc. Basically, a slideshow. This works great with smaller amounts of images. But with a whole lot of images, I'm sure it will take a HUGE amount of time to retrieve the images, etc. I have not research JSP, and I was wondering if this application would be better suited for JPS instead of applets. Also, if so, if anyone has any suggestion on where to start, maybe some links, or tuterials, it would be greatly appreciated.

Well, you could certainly do a slide show with JSP... actually, you could do it with Javascript and plain HTML (one example is weather.com, they have this "show map in motion" option on most maps, which is done in JavaScript).
But I think the reason you are having problems is it sounds like you are trying to load all the images at startup. You should only load each image as needed, stored in memory after you load them, of course. This would really be the same way it would happen as a HTML/JavaScript slide show, since you wouldn't really have any other choice.

Flipped Image

When I run the isight camera in xp via bootcamp by double clicking the isight icon under my computer a screen pops up allowing me to take pictures with it. However, the image is flipped horizontally meaning when I move to the left I can see the image of myself moving to the right. Any ideas how to fix this? Thanks.

Nope, printing to a PDF "unflips" the image. And I get the same behavior printing to both my Epson photo printer and a Samsung laser printer. Not a huge deal, if I un-rotate the image and print, it prints flipped. Tried it with a recent digital (not scanned) image and got the same behavior. I discovered the "problem" after scanning a B&W negative taken back in 1973. I use an Epson V600 scanner and normally flip and rotate as part of the scanning process; however the scanner had problems determining the edges of the 35mm frame since it is a picture of a window surrounded in black. I had to resort to using the marquee and manually selecting the frame to scan. Doing so doesn't allow you to flip and rotate during the scan, so you have to do that in Aperture.
Again, not a big deal as long as I know how to manage it. And I rarely flip images - only in the type of situation noted above. I almost would not have noticed it, except that I was comparing the inkjet print to a silver print I made of the negative back in the '70's.
Thanks for all the suggestions to try and narrow this down, but I am perplexed that you do not seem to get the same behavior.

Aperture 2.1 and Adobe Photoshop CS2

Hey.
I'm using Aperture as my bread and butter. I don't have any issues.
In my previous posts I mentioned that I don't use Photoshop, but now I'm using Photoshop a lot more...for retouching and localized corrections.
All of my tonal corrections and things are done in Aperture and I just export 16bit PSDs to do retouching on and then bring them back into Aperture. Pretty smooth workflow and still rely on Aperture, not Photoshop.
Anyone else enjoying the strengths of Aperture and getting the benefit of PS like that? I haven't used the spot and patch much in Aperture, but I will try it soon so that I can minimize my PS work even more.
Anyway, Aperture is still working great for me. Hope it does for you, too.
Scott

Yes. Aperture cut my PS CS, CS2 and now CS3 workload down from 100% to around 5%. A huge time-saver, plus of course the image management side that CS2 or 3 doesn't do (and I include Bridge in this).
The new spot/patch brush is night and day compared to the original. It is fabulous (better than CS3 for many tasks) at identifying edges and adjacent textures. Highly recommended.

Lightroom 5.7 in Windows 8.1 and MIDI controlers

Hi,
I am looking for a plug-in or other option with what I can use for example the Novation Nocturn in the develop module in LR.
But for Windows there is probably no solution aviable There is "Paddy", but that is outdated and not working..
Actually I dont undersand, why there is no native support for MIDI controllers, the potential is huge, just turn knobs and edit the image..
Any ideas or solutions? Or at least a explanation why this is not possible..
Thanks

I've never heard of someone editing photos on an audio mixing desk.
And - you have to ask - what benefits would come from being able to do so (or otherwise controlling via Midi)?
Fast editing, controlling more sliders at once, using the mouse or tablet just for brush work or cropping, the rest with sliders or knobs(the better choice), you could look the most time just on the image and the changes, and have no need to look on the sliders.
And just that physically feeling..
Oh and actually like I wrote, solutions are existing, but mostly for Mac(Knobroom,PFixer), and it makes sense..the mapping under Paddy is pretty nice, an example image of a list is here. And you can set the functions for more "pages" on the controller, that means you can set really tons of settings. But Paddy "works" for LR 5.2 in a beta version.. You can find Youtube videos, mostly for the Mac plug-ins

I've lost the histogram - and other adjustment woes

I filed a rather long description of this to the Aperture Feedback, but as I suspect that is a "write only" channel I thought I'd ask here (and I did review a bunch of posts with no luck)
I have a brand spanking new MacPro quad, with 2 NVIDIA GeForce 7300 GT video cards (I mention this only because of Aperture's use of GPUs).
In summary, I imported a project that works fine on my MacBook Pro, but on my MacPro the histogram in the adjustments HUD is gone. When I try to make an adjustment, a HUGE black triangle appears where the preview image was, the histogram magically appears, I make the adjustment (the slider is not smooth), a full second passes and the preview is updated with the adjustment -- and, of course, the histogram disappears. When the system is feeling particularly nasty, the preview comes up completely black after the adjustment (although the thumbnail appears to be updated properly).
Suffice it to say I've tried everything but yank out the RAM and the GPUs... I've seen this on some images in other projects. I created a new Aperture library and loaded some images (from different cameras) -- all exhibit this behavior. I've stopped and restarted Aperture. I've shutdown and restarted the MacPro. I've reverted my profiles for the displays to the Apple defaults. I've started considering moving to Lightroom...
Aperture is such a wonderful program when it works... I've had a bunch of minor issues with the program over the past year I've been using it - but this is insane.
If anyone can provide some clues as to how to fix this I'd appreciate it.
Thanks,
- dave
Note: A small update to my post. I thought the histogram had disappeared, but upon closer inspection it is there -- but it reads as if it were a completely black image (e.g., all of the values are in the first column). Another clue...

Photoshop CS6 icons sometimes do not appear on Macintosh

Yes, this is a question.
I've been using my trial of Photoshop CS6 Extended for 10 days now. I have run into a peculiar problem - when saving a file Photoshop does not display any sort of icon. No thumbnail, no generic, nothing. It's not a huge problem, I can always open the image but not by double-clicking on the icon: it's just not there.
I'm wondering if anyone else has had this problem and if there is a resolution to it - or is it just a bug? I didn't have this problem with the beta version and I've repaired all permissions on my hard drive to see if that was the problem.
Any help would be appreciated.
Regards,
Clinton

Clinton, I'm experiencing what sounds like the identical problem (running Mac OSX 10.6.8) ...
- It happens with .jpg, .png, .tif,.psd and Photoshop .pdf files - and therefore is not related to alpha channels
- No other app on any of the Macs in our shop, running either Snow Leopard and Lion has - or has ever had - this problem
- Re-opening the files and re-saving in the same format using any other graphics utility (Preview, Graphic Converter, AND Photoshop CS4! creates the icon successfully.
- Deleting the .DS_Store files for any given directory does not eliminate the problem
- Repairing disk permissions does not eliminate the problem
Only thing I haven't tried yet is rebuilding the entire volume in DiskWarrior - that is next.
I created 7 identical copies of the same stock photo in different file formats (.tif, .jpg, png, psd, .pdf) - Only #6 (re-opened in Preview and re-saved) and #7 (saved in Illustrator CS6) are displaying file icons.
Would love some real help from Adobe on this...
UPDATE TO THIS POST
Deleting the .DS_Store files for directory and restart appears to solve the problem...

Mac Pro with Aperture - very slow

Why, why couldn't it be faster?
I've been reading about the Mac Pros since they were announced last week. The local Apple store finally got one and I went to go see it. And there it was -- 42 lb glory, standard configuration, driving a 30" screen.
I launched Aperture... and it's slow. I mean really slow, spinning pizza wheel slow. Granted I'm trying to bring up full size raw images that are ~16-18 meg each. But come on -- this is a workstation class machine! The "fastest Mac ever"!!!
Showed it to the guy working there. He said they installed the box today with a brand new disk image and sometimes the image is bad. "Ben" promised he'll call their engineers to see what's up.
So what's going on here? Some ideas:
* Aperture is very Core Image intensive, and the standard GeForce 7300 card isn't that fast. I plan to upgrade to Radeon X1900XT - people say that will likely make Aperture faster.
* The photo files were huge, 16 to 18 mb each. Raw images my camera takes are 6 meg. At least until I upgrade my camera.
* The box had 1gb of memory - standard configuration. Would more help?
* Maybe there really is something wrong with the box or the disk image.
Disappointing...
Mac Mini Mac OS X (10.4.7)

I dont really post very often here but i think it is yet time to give again out a few pointers about Mac performance ...
1) Whatever the configuration ... Ram is essential and shall never be ignored .
2) Whatever the hardware platform your machine is running on check your software version and keep up to date , that goes 20 times for anything Universal Binary.
3) When treating high volume files Hard drive space is ESSENTIAL and not only necessary and frankly setting up a raid from a Mac is still seamless and fast.
If you all made it through to this point then your mac is becoming a powerhouse never slows down and really smiles and keeps on coming ... i have been running G5 machines for a long time on mac os X servers since the G5s came out and before that were yet G4s . First thing you need when dealing with large files is RAM second drives and third software versions.
I would not dream running anything with 512 mb of ram at all that is a constant on all macs , you have a memory expansion capability to 16GB mmm that shall really help .
Further you have 4 bays for drives ... may i dare think they are here for some reason such as treating high volumes files ?
Third and foremost when using nvidia cards dont expect superb performance on a 30" screen when using the FX4500 card since nvidia cards have a really bad record on that matter with the G5 .. would you deal with massive 3D open GL etc etc etc ... ATI is it plain simple and really outperforming it has always been the case for macs .
Yes, ATI X1900XT are rare now because of delays but the cards are no slugs on a mac and they mean business when running on 30" screens . A pci-x X800xt radeon card running on a previous dual processor machine kept kicking the Quadro running off a PCI-e on a quad machine ... we then tested with a X1900xt prototype and again the world changed .. all the things the nvidia card could not deal with the X1900xt just smiled at and kept on chomping non stop .
I did not still get aperture since i have yet little need for it but my educated guess would be that with a little ram a nice set of raid array (you dont need 15k rpm drives unless you treat live HD solely on a internal array) and or an Xraid setup the machine would just scream in performance. If you use the machine for production processing power of the chip is just a tiny part of the whole performance equation thinking about streamlining your pipelines and data flow takes your setup to whole new grounds.
A quad running 4D server Maya some data backups mysql and about 103 processes is occupied about 10 percent load averages .....
secondly regarding disk images and apple installs errr please take the time to install everything from scratch i am guessing aperture you just have seen running might be using rosetta and is just a transfer from a G5 that would explain performance issues . 18 Mb a picture is not huge ... we use about 100Mg images on PS maya strata etc etc etc and frankly image size with a bit of ram never has been an issue.

ZOMG PLEASE HELP! - ColorMatrixFilter - How to set a SPECIFIC HLS to a greyscale png

I am able to use the color matrix filter to change the pngs
that I am loading dynamicly. Thing is, I can't seem to figure out
how to apply a SPECIFIC hue, saturation and luminance.
Basically I can successfully modify my grey scale png to all
sorts of colors already. I need to be able to colorize them with,
for example I would in photoshop put in H:212 S:36 L:-48 and it
would turn out a great blue... how do I turn those numbers in to
the proper color matrix to be applied?
I have done a good bit of research on hls/rgb and also tried
using this adobe sample app to put in numbers similar to above,
expecting to get a matrix that would apply those transformations.
Using the resultant matrix, the image stays at a very low
saturation even when using positive luminance values. I could guess
at it, but I have a bunch of PMS colors I am going to have to
match... SO at least being able to convert HLS or RGB into an
applicable color matrix with predictable results is needed.
Here is a sample of what I am trying to do, but just using
CSS and JavaScript.

- Since it is using pngs you can't use internet explorer to view it
properly. But even if you have only ie, you can see that changing
the selection in the lower drop down box shows you a different
color of the shirt. All of these images were colorized in photoshop
from the same source image I am using in the flash application. I
need to translate the HLS numbers I used in photoshop into
colormatrices to apply to the same image.
Here is what I have so far for the flash application.

- If you don't see the flash app, try in IE, I have not bothered
tweakin anything as far as html because I am stuck at this issue.
The buttons are not marked right, start at the top and go
down, you'll see what I mean. I can apply the color matrixes and
the effect is working, but HOW DO I GET THE SPECIFIC MATRICIES FOR
SPECIFIC COLORS?
Please help :o) Thank you in advance.

Thanks for the reply. I've seen every example out there I
believe. From satori color to quasimondo. The problem is not making
it work. The problem is how to make it show an exact color.
How do I use colormatrix to colorize a greyscale image to a
SPECIFIC color. It's a great tool and I can change my greyscales to
all sorts of colors, but how do I make them a SPECIFIC color, like
with setrgb I could just set the rgb, if I have hls values how do I
convert that into a useable colormatrix to modify a greyscale.
For instance: (please read)
In photoshop I would adjust hls and put in say: 212/60/60 for
a nice blue, apply it and my grey scale is now a nice blue.
In flash, how do I use that info to change the grey scale
image to the same color?
