Hello!
I'm evaluating Qimage.
I think that it's a very good software.
Now my consideration.
I'm trying to print a photo on A3+ on my HP B9180.
Very normal task, you will think.
Probably, but with some difference in my case.
I start from a file acquired with my Howtek 7500 from a positive 4x5" at 5.000 dpi (or ppi if you prefer).
I've pixel to print an image at 300dpi as wide as 80 inch.
I want to print at 1200 dpi on A3+.
On the widest dimension I need 22.820 pixel and I resize down (a little) my image.
The file in jpeg compressed is about 130Mb.
Once opened it's about 1Gb.
This dimension shouldn't be exaggerate for Qimage because it simulate (using interpolation) the presence of file like these.
The only issue is that the software don't work with such big files.
I've two different results.
If the file is big too much (I suppose over 500Mb) it display "Image read error" in thumb (obviously no error in file itself).
With good compression the file (jpeg) goes down to 130Mb.
So Qimage display well in thumb and try to print.
After print command, appear a message "Qimage could not load the file : xxxxxxxx Current session aborted" .
So, that's all.
If I want to print a file from my EOS 5D and Qimage has to "create" pixels using interpolation there isn't problem, the software works good.
If I've all pixel acquired of "real information" I can't print with this "Professional" software.
 

(sorry for my english ... )

Many thanks for reply Fred, it's a jpeg with sRGB as embedded color profile.
I've noted that with psd there is some problem and I've saved in jpeg.
 

Just an aside, Fred, I had the same error yesterday.  Really wierd.  I scanned some old photos for restoration using Vuescan.  I used the option to save TIFs and save RAW (which Hamrick saves as TIFs).  QI will not see them.  Breezebrowser and PS do--both the regular and the RAW TIFs.  300MB files

QI does fine after PS saves.

So, we might need to know what software he is using on the scanner.

I believe you are looking above the upper right preview panel which is telling you the driver settings for input ppi.
All that means is that Qimage will interpolate your image to 1200 ppi and send to the printer.

A 1.3 gig file is likely too large for Qimage and your available resources. To check this, Hold the shift key while Qimage is open, and click HELP and Analyze current settings.
You will get an approximation of the amount of resource you have and what size file can be processed by Qimage.
I also believe that you are saying that the 130MB JPG is not reading nor printing. How was that JPG created?

Fred

But I'm afraid it is a problem. Windows memory management is not very clever (I think Vista is better than XP) and Qimage is telling you what it sees as available. There may be programs or services running in the background that hog the resource or Windows has not freed up the memory - I think that is correct from memory of Qimage's author's (Mike) explanation in the past.
Thus your file needs to be below 798MB.

Hopefully Mike can give a better answer than me, but the Windows XP Operating system does have limitations.

I believe PS does it's own memory management to overcome Windows problems.

If you want to use the best printing program available, and one that can PRINT larger files than PS can, then you need to manage your file sizes. Top Pro's across the World use Qimage quite satisfactorily to make quality prints Metres long so there's not much wrong with Qimage.

Unless my arithmetic is faulty, and that can easily be so, you are scanning at an unusually high resolution.

4 x 5 at 5000 dpi (25000 x 20000, times 3)   1.5 gigabytes
Try dropping the scan resolution to 600 DPI.
