Hello,
A file I just created with Photoshop gets an “image read error” in Qimage studio version 2010.208.
The size of the tif file is 496,135kb
The size of the psd file is 780,086kb
There are no alpha channels or layers stored in the files. I did a search on this and came up empty. Any suggestions would be appreciated!
Thanks

Justan, There are no alpha channels or layers stored in the files. I did a search on this and came up empty. Any suggestions would be appreciated! The first thing that comes to mind is this screen on saving a TIFF. See attached screen snap. See that the items Pixel order and byte order especially, are set correctly. Fred |

Hi and thank you for the quick reply!
The settings are as shown above. I also checked and have no alpha channels in use nor do I have any guides on, which I've found in the past to cause problems for qimage. But I'm thinking it is something along these lines.
I work with panos and have lots of them, many of which have substantially bigger files sizes that i've used as recently as today. One thing of note is that the source document, a tif file with layers, complained at one point about being at the 4GB limit for tiff files. Does Qimage have any problems with CS5 and anything that may be in a single layer tiff or psd file? This is probably too general a question but it's a place to start.
Baffled by this one....

Let's get a read!
Click HELP, then hold the SHIFT KEY down when you click Analyze Current Settings
Then we need the numbers that show up.

Start: 764 MB
Addl: 448 MB
Now: 256 MB
It’s definitely an odd one. I opened the file in cs3 and can print from there. Tried to save as a 1 layer tif and psd from cs3 and while the saves were successful, qimage still gives image read failure.

Justen, Thank you for the report. Start: 764 MB
Addl: 448 MB
Now: 256 MB This is definitely insufficient resources of your computer. You need to either get more memory into the equation or turn off a bunch of stuff that is hogging the memory. Which Windows version are you running? Some of the folks on here can advise you on tricks on certain Windows versions where you can squeeze more memory usage from Windows. It's a switch in XP I believe. I have no special high powered computer. Mine is well over 3 years old, with 4 gigs of Ram, running W7 and my readings are: See Screen snap attached. So until we get some decent readings, we are not going to even look at the files. Try typing MSCONFIG into the the Windows Command Prompt which will bring up a box. See second screen snap. Your Antivirus program *does* need to load on startup, so leave those type of programs alone. Then see third screen snap, and try to uncheck programs that do not need to run all the time. For example, Photo Shop does not need to run and hog memory when not in use. It will still open and run on demand as usual from the desktop icon. Same for many others. Then reboot. Retry the resources test in Qimage. Fred |

Thanks again for this feedback. The computer is an XP box (x32) with 4gb of ram, of which about 3.5 g is identified by the system. The startup programs are minimal as it goes. The computer uses about 320 MB after boot, according to task manager. I did a reboot and the Qimage numbers were much higher but still it would not read the image.
This image is very wide. Photoshop measures it at 17195 x 3693 pixels, (12.31” x 57.31”). Does Qimage have any issues due to the image width?
Don’t know off hand if I've done a longer tif before but this is not even close to the largest tif file I work with by way of byte count. Qimage has no problem opening or working with images of a larger overall file sizes. I have 5 of them in the same directory as this one, which are between about 800 MB and 3.5 GB and Qimage works fine with those. This one is a comparatively small ~ 780 MB.

Hi, The startup programs are minimal as it goes. But they or something else is using a large proportion of the memory. Have you actually run MSCONFIG as Fred suggested? You could try using the 3GB switch for XP; that will increase the available memory. You'll have to Google for information about it. Does Qimage have any issues due to the image width? No. Photoshop measures it at 17195 x 3693 pixels That is equivalent to 190503405 (17195 * 3693 * 3) for RGB) so even with your poor resources, it should be ok with Qimage. There's something else going on with that image by the sound of it, or Sorry I can't offer any more suggestions. Terry |

Justan That is equivalent to 191MB (17.195 x 3.693 x 3 for RGB) so even with your poor resources, it should be ok with Qimage. There's something else going on with that image by the sound of it.
Sorry I can't offer any more suggestions. Is there any way you can get a copy of the smallest file that shows Image Read Error sent to me? I did a reboot and the Qimage numbers were much higher but still it would not read the image. Can you show a screen snap of the new revised memory readings, or can you remember it exactly? I am referring to the HELP, Hold Shift, Analyze........ If I can get the file, that would help. Right now, I am leaning toward insufficient resources.... BTW on a clean boot up with email and forum open I can count over 800 Mbs of memory in use. 320 seems awfully low. Are you sure you have Show All Systems checked? What were the new numbers that Qimage showed.? Fred |

Thanks once again for the feedback.
>There's something else going on with that image [file] by the sound of it.
That’s what I suspected. I decided to work up the file again rather that continue to screw with the problem. The newly created file prints through Qimage just fine.
I can only surmise from the obvious that that Qimage doesn't like something in the original file, even though Photoshop has no problem with it.
In the past I have come across instances where Qimage gave the image read error and that was due to something in the file Qimage didn’t like. One time it was alpha channels, another time it was a view guide. However, again, in this case, the files are 1 layer tif or psd files which contain neither alpha channel nor view guide enabled.
Anywho, again, my thanks for your feedback. Even with it’s occasional Quirks, it is a good printing utility. It would be better if things such as this didn't cause delays but I'm glad to resolve the problem after only a half a day of work.

You would expect PS to be able to read its own files containing non-standard stuff  Even with it’s occasional Quirks, it is a good printing utility It's unlikely to be Qimage quirks, why not Adobe quirks? They seem to have a habit of messing up images; there's been a recent thread here where CS5 was putting junk into jpeg headers and Mike, to satisfy his customers, has modified QU to filter it out. Qimage is not merely a "good" printing utility, it is World Class with its unique method processing for printing including the interpolation algorithms - and all its other features. No apologies for being an enthusiast  Terry |

Justan, I have to echo Terry's comments. Qimage Ultimate tries to conform to the standard set throughout the world for Color Management and has set the bar for excellence much higher than your Photo Shop. You must read this post from Mike Chaney to understand that "might does not make right". Just because Photo Shop likes to portray itself as omnipotent you do not have to close your mind. They make mistakes. You see the mistakes, and then blame the incompatibility of *their* peculiar and aberrant save routine on Qimage? As you can see, and by what Terry tried to explain, in order to save many people from having color profile problems when saving or creating a file in PS, Mike made a work around fix. As you can see from the post, it is likely that PS will fix *their* blunder, and it will be corrected in the CS6 and you will likely pay for that fix included in the price of CS6. Please read: http://ddisoftware.com/tech/qimage-ultimate/qimage-exposes-photoshop-cs5-%2812-0-4%29-jpeg-corruption-bug/Best to you Fred |

Hi Terry, Thank you for your comments here and above. >You would expect PS to be able to read its own files containing non-standard stuff Yes but what evidence is there that something is was non standard in the file? Even with it’s occasional quirks, it is a good printing utility > It's unlikely to be Qimage quirks, why not Adobe quirks? This is a deflection. > Qimage is not merely a "good" printing utility, it is World Class with its unique method processing for printing including the interpolation algorithms - and all its other features. No apologies for being an enthusiast Terry I work with PS as my production tool of choice. I want support programs that get along with it. I'm sure you understand that if a support tool doesn’t do the job, it becomes an obstacle. I like Qimage. I've been using it for all my photo printing for a few years now and would have problems printing without it. There may have been something unique about the file that motivated the problem. But in the end, I'm after a solution. If PS can work with single layer tif of psd files, I’d expect Qimage to as well. It would be odd for someone to find that an unreasonable expectation. |
