CS4: Content Aware scaling never works....

Quad 2.66 Xeon MacPro
16GB RAM
Dedicated 250GB internal Scratch Drive (Not a volume)
2 nVidia 512mb 8800GT video cards.
Whenever I choose "Content Aware Scale" the transform handles appear, I alter the image, ht enter to commit and I get this:
>Could not complete your request because there is not enough memory (RAM).
Huh?
The file I'm working on currently is only 37.5mb in size, 2599x2592 pixels, two layers ...
But this error presents itself with each and every attempt to use Content-Aware scale.
Any help?

so I'm not the only one who has problems with content aware scaling -- but there is no current discussion about it and I'm not sure what to do now.
Im on a mac book pro that i bought october 2008 with 4 Gb RAM, with a 2.8 GHz Intel core 2 duo processor. I run content aware scaling on a file and get the warning dialogue: Could not complete your request because there is not enough memory (RAM).
People have talked about CAScaling not working well with Bigger tiles plug in activated. as far as I can see I do not even have that plug in. I go to apps>PS CS4 >plug-ins > extentions -- and it's not there -- I see plug ins for AltiVecCore, Enable Async IO, FastCore MMXCore, Multi Processor Support. PPCCore, and scripting support -- but not a Bigger tiles plug in which I still have in my previous copy of CS3 -- but not CS4.
So I'm wondering what's up - how to solve this issue and get back to work -- and just how I should have my PS performance preferences set up for best performance. Anyone out there with a clue?
thanks,

Content aware scaling

I am trying to use "content aware scaling" in Photoshop CS4. But every time I try to use it, I get a "program error" messaage. I select the image, try and resize it, but when I click for content aware scaling to work, the error message comes up. ( I am using windows XP, if that means anything).

May I respectfully suggest you polish up your skills on searching for things on the Internet...
Google turned this up in about one second after I entered "picture package CS4 download" into the little box at the upper-right corner of Internet Explorer: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4048

Problems with Clone Tool / Content Aware Scaling in CS4 Mac

I've been using PS for about 1 year and a half. Sort of an Advanced beginner. One of the things I love is the clone tool. Since I've upgraded to CS4 I've had nothing but problems with the Clone tool. When I go over an area it doesn't show anything and the either makes the adjustments after a long delay or it goes black and then comes back with the adjustment. Sometimes when I'm dragging the brush the whole picture goes away replaced by a smear of color noise. It really makes the tool unusable. In many cases I've gone back to CS3.
I also have similar problems with the content aware scaling. Never been able to get it to work. Basically some of the nicest new features of CS4 are worthless for me. Tried looking at Adobe solution and searching the forums but I haven't seen any exactly similar problems of solutions.
Any help appreciated. I have a white 24' Intel Mac with a 2.33 GHz Intel Core 2 Dual with 3GB RAM.

As always the various User Forums are fantastic. Adobe (and other) get everyone to do their Tech Service for them. Thanks for the help.
So, two new pieces of info. When I disable Open GL everything works fine. (Sorry about the TIFF, I just didn't catch it) So in essence this solves my problem.
Also PS CS4 works perfectly on my new Aluminum MacBook. So clearly it is an issue with the video board on my iMac.
This brings me to the wrap-up question. Should PS CS4 theoretically work with Open GL on my iMac or is it a know problem with CS4 and older graphics boards? I'm assuming my board supports Open GL.
This is the Profiler data on the Graphics Card
Chipset Model: NVIDIA GeForce 7600 GT
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 256 MB
Vendor: NVIDIA (0x10de)

iMac:
Resolution: 1920 x 1200
Depth: 32-bit Color
Core Image: Hardware Accelerated
Main Display: Yes
Mirror: Off

Quartz Extreme: Supported

Some of the Open GL features are nice and wouldn't mind having them but not worth buying a new Mac for. So the questions is: Is the some kind of upgrade / driver I can load to solve this problem.
Again Thanks for the help

Content Aware Scaling--Upscaling isn't working?

I am using content aware scaling. Everything works great until I try to upscale the image by dragging the corners. When I try to transform to the larger size, the part that has been widened is "hidden." I know that it is larger because I can "move" it within the white box that marks the original size, but I can't make the complete upscaled image appear. Can anyone help with this? Thanks!

After content aware scale, go to Image>Reveal All
and see if that helps.

Content Aware Scaling and not enough RAM

I'm on a mac book pro that i bought october 2008 with 4 Gb RAM, with a 2.8 GHz Intel core 2 duo processor. I run content aware scaling on a file make my adjustments, click return and get the warning dialogue: “Could not complete your request because there is not enough memory (RAM).”

I think I discovered the source of my problem -- doing too many things at once -- I did however , as you suggested, Buko, allot 90% of my RAM to photoshop. My image was a panorama made from seven RAW files shot with my Canon G-10 -- about 15 inches by 63 inches @ 240 ppi. I first stitched them together out of Lightroom -- no problem. But of course the edges were rounded, and I wanted to stretch my sky and foreground to fill the image rectangle without any apparent distortion. I figured CAS was perfect for this... and so it is, once I figured things out.
It is now my intent to stitch the pano every way possible in CS4 and see which one looks best in this particular instance. I may have multiple favorite methodologies, and discover which procedure fits what kind of situation best. My problem, I think, was that in applying the CA scaling transformation, I pulled on all four sides of the image - not just one. But PS and CAS worked just fine if I transformed each edge or side separately. Perhaps it works fine pulling and transforming on all sides if I'm on an 8 core mac pro tower with 16 gigs of RAM -- we'll see -- but for now -- I'll try it separately with each edge @ 100% RAM allowance -- to see if that had anything to do with my problem -- otherwise I'll keep it in the optimum range, and transform one side at a time.
For me this file was a test -- I have a panorama of an image looking over the rooftops of Siena, Italy to print next, made from 17 frames from my 5D mark 2 and that file is 3.3 Gb and took my little laptop over an hour to render as a pano -- but it did-- ( thank you apple -- thank you Intel, thank you Mr Knoll & co...) and will need some stretching to fill the frame -- one side at a time - I suspect.
So merci beaucoup, Buko!
... and thanks Mr Schewe for the the tip, doode -- you know what I'm talking about. ;^) and thanks to the engineers and geniuses at Adobe who make this magic possible.
peace,

Content aware scaling - getting very poor results for architecture

I am evaluating CS4 to see if I need to upgrade. I am not excited by the UI changes form CS3 so that is not a reason alone to upgrade for me. I am hoping that content aware scaling is that reason. I shoot architecture and many times there is extreme edge distortion from using really wide angle lenses. I try not to use those lenses but sometimes it is unavoidable. I am not talking about barrel or pincushion distortion. Alot of times there is a chair or a table on the edge of frame that gets stretched and it takes alot of scaling and warping to make it look not as bad. I tried to fix it with content aware scaling using a protection channel but the results are the same as using regular scaling. Am I doing something wrong or expecting too much? Any help would be appreciated.

if quick selection can select an object like a chair or table without too much difficulty, I thought content aware scaling would recognize those elements too like it supposedly does people. if it can only work with vague content like skies, ocean etc than I have no use for it.
and if thats the case i would skip this update and wait for CS5, i don't see much else to get me to update. unless there were other transform improvements.

Content Aware Scaling on Video Layer

Hello,
I hope this is possible because it works really well on still frames but how would I go about applying content aware scaling to a video layer inside PS? Basically I'm trying to use this feature to fake an aspect ratio change where by I have a subject surrounded by a relatively uniform background and I would like to be able to create a protection mask as an alpha layer and have photoshop apply the content aware scaling only to the background(to fill in the empty parts of the rescaled video) and leave the subject untouched.
What I've done is opened a video in photoshop as a layer, created an alpha channel to represent the subject(subject is white, background is black on the created alpha channel), changed the canvas size to the new aspect ratio which obviously created a tranparent frame around the original video frame. I then tried to apply content aware scaling to the video, it converted the layer to a smart object then displayed the free transform handles. However, when I selected my alpha channel as the protection area, the content aware scaling seemed to ignore it and went on to distort the entire frame. Now I tried this with still frame from the same video with the same mask/alpha channel and it worked as expected just didn't seem to do it with video.
The idea, if it would be possible to do this in PS, is to rotoscope the subject roughly in AE and generate a matte pass which can then be used as the acompanying alpha layer of the video so then the content aware scaling can be applied to each invidividual frame.
Is this possible??

No that's not what I was trying to do, I mask the central subject of my frame and as I said it was surrounded by a fairly uniform background(main subject is a rock formation in the middle of the ocean) I want to change the aspect ratio of that frame, so I created an alpha mask to cover the main subject, the surrounding background was not covered in this alpha channel mask. This way when I scale using the content aware feature all that happens is the background(the water) is streteched evenly with lesser distorion(than normal scaling) while the masked main subject is "avoided" with completely no distrotion. I think the key point you missed in my description is that I am in fact creating an alpha matte for only my subject not the entire frame and using that in the "protect" option of content aware scaling.
The result is essentially a frame aspect ratio change that does not sacrifice the resolution around the main subject(because the main subject remains of the same size and PS doesn't have to interpolate any pixels...this is obviously is not the same as just resizng and cropping where the subject and background are streched evenly to fill an essentially larger area of the screen causing "softness"). The result using this method is also much more predictable from frame to frame than content aware filling because it's taking information from the current frame and using is to fill the empty background resulting from the aspect ratio change. I know this works because I tried it on individual still frames from the video then compiled them back in on AfterEffects...thats not my problem. My problem is when you try to natively try to do this inside PS on a video layer(rather than a still frame) it doesn't work and I'm not sure if this is a bug or if video content aware streching is just not supported.I have CS6 Production Premium.

How to only have 1 image with content aware scaling

My knowledge (lack of, really) with content aware scaling is that 1st you create a new layer of the background and then rescale accordingly. I did the following: -1- Created a 2nd layer -2 used quick selection tool on my main subject ( a person) and named it. -3- deselected the selection -4- Edit menu --> Content aware scale -5- resized it to something smaller (chose my previous named selection channel). -6- Pressed "Enter"
The result is that I can now see 2 images; the smaller sitting on the larger. What now? All I want is the smaller image. If I throw away the original layer what I end up is the new layer with the white and gray default background showing as part of the image (which ends up being printed as well or if saved looking as is with the grey-white. Is what I should do the obvious--cut out via cropping the un-needed (gray-white) part? Or am I missing a step somewhere?
Thank you

My changing of image size had always been either by using the crop tool (which of course also removes parts of the image), or going to the top menu and choosing 'Iimage Resize' ( Alt + Ctrl + I). So using any method other than the one described alway had 'Content Aware Resize' greyed out and therefore unuseable hence me thinking a 2nd layer needed to be done. I had not been aware to use the marquee tool--so thanks. Either way though, when scaling down, it seems that cropping needs to bee done just the same. I was hoping there was a method where this was not required and could be done directly. Your method was defnitely helpful and saved me a step nevertheless so thanks. BTW, if I may, why does everywhere I go and have seen always show to create an extra layer? Your method seems to be better and actually shows creatin an extra layer to be totally useless so that is why I am asking since it seems to be totally not needed.

Help!!! My Content Aware has stopped working.

My content aware feature stopped working. It worked for about 6 months and then stopped functioning correctly. I tried deleting and reloading the software, and this also did not work. I select an area to fill and choose content aware and it will only fill it partially. I am unable to post a capture of what this looks like. Basically, when I try to utilize content fill..the result is a semi filled section. It looks as if it glazes over the selection..leaving it visible but partially filled. This happens regardless of the selection size, area of the photo etc.

Discussion locked so that it can continue in : http://forums.adobe.com/thread/1025351?tstart=30

Can't get Content Aware Extend to work

Read all the tutorials but when I make a selection and select content aware extend it just moves the selection without extending it. Need to find some way get it to actually extend?
After making a selection, the "move" and "extend" options appear to do exactly the same thing.

OK, I got it working now but it does not work very well, or as expected.
This is more of a move and replace tool rather than an extend. It is labeled wrong. While the move tool fills in the space left behind, this sort of leaves the selection there and duplicates the selection to move. Not very useful. Can be better done better with the clone tool.
This tool also errors out quite quickly as you mentioned by moving the selection too far yet does not tell you. The problem is there is no feedback from the SW that it has errored out and can't do anything.
What would be helpful would be to create a REAL extend tool that duplicated repeating pixels between the selection and the current position.

Content Aware Tool Not Working As Expected

I've been watching a whole bunch of training videos on PhotoShop CS5 regarding new features lately, been running the trial of CS5 on my Windows PC for a few days now.. Pretty much everything works as advertised, but I can't seem to get the Content Aware tool to do everything I've seen it do.
My main question is regarding the dialog box that is supposed to pop up when pressing the delete key while an area is selected. Doing this simply deletes the content of my selection as previous versions did. Is there anything special I need to do to get this to work?
I use PS on my computer at home, and I don't have internet access there unfortunately (only at work), so I can't even get to the help options... Maybe some sort of installation package for the help file would help answer this and many other questions, if anybody knows where I can get that...?

On a PC you hit the backspace key rather than the delete key and that will bring up the content aware
tool.

Photoshop Elements 13 Content Aware Fill Not Working

Hello, all. I am sort of new to Elements 13 and seem to have run into a bit of a blockade. I'm trying to eliminate a tree in the background of a photo with content aware fill capability; however, when I try this it loads as if it's working on it but when it's finished nothing has changed. I thought perhaps it wasn't prominent enough to recognize what to fill (which did seem unlikely), so I went ahead and tried it on something more isolated and still nothing is happening. I feel as though I must have something set incorrectly because a lot of my other tools aren't working either, but I can't imagine what it is I've done wrong.

When the editor gets weird, the first thing to do is to delete the preferences. Go the editor preferences>general, click this button and restart the editor:

Clone, spot healing tool, content aware will not work on 11 or 12

The following tools will not work on PSE 11 or 12: clone, spot healing, content aware. Using 3 yr old iMac with latest OS. Same problem on Mac Book. I must be something wrong.

I'm not sure what was going on. I eneded up discarding the photo I was working on and open up another one and everything worked. I guess just a little hitch in it's gitty-up!
Thanks for your comments.

Content Aware not always working?

What are the specifications for how to make content aware work? Sometimes I delete something and it asks for content aware, but other times it just deletes it. Do you know what's up?
-TitanVex

Could you post a screenshot of the dialog?
Could it be you actually hit shift-delete instead of delete?

Can't execute content aware scaling - out of RAM message

Cs4 extended. "bigtiles" plug in not loaded. This is trial version, I haven't bought upgrade yet......but this feature is key for me.
Vista 32 bit, 4gb ram, 32gb available on HD
I keep getting the "can't complete because not enough RAM" message
I tried a)converting to 8 bit file. working file size is 41mb
b)increasing amount of ram used by PS to 80%
c)removing most other processes from running.
efficiency still show up at 100% during process.
Anyone have any ideas? shouldnt my system be able to handle this?
thank you

I don't think the scaling is meant for alphalized/transparent content and selections. After all, it is based on detecting contiguous areas and unique structures in the visible pixels... You may simply need to adapt your workflow and way of thinking for using this feature most efficiently.
