I tried the search function here with no results, I hope I am not asking a question that has been handled here before.
I have used Qimage for years.
I am starting to print large- really large. 40x60" routine. 40x100" not unusual.
On my largest files, I get an " Image Read Error." If I take the same file and downsize it Qimage builds the thumbnail and can print, so it is not the file itself. It is the size.
I would like to stay in the Qimage environment.
As an example one pano is 12633 x 19043. 688MB. Gives me an Image Read Error
Any idea of how I should handle these very large files?
Thanks
Gary

Gary Gary, I just built a file to your specs....722MB Works fine. So it seems as if we should look at your system. Which windows? 32 bit or 64 bit? How much RAM available? What other programs are running at the time along with QU? If my memory serves...... I think around 1.2 gigabytes was the max size. Do a HELP ANALYZE while holding the shift key See screen snap Win 10- 64 bit with 16.0 gigs of RAM Fred |

One year old build What about something else with heavy RAM usage running? What numbers do you get when you click HELP, and then click ANALYZE with Shift key down? Otherwise I am stumped. Will have to pass it on to Mike. I assume the pano was stitched. What software stitched it? Fred |

Pano stitched with photoshop as a tiff.
Other large files enlarged with topaz Gigapixel
Nothing else ram intensive running- and the image read error is permanent- it does not "correct" over time.
Information:
Start 2145MB
Addl: 909MB
Now: 2145MB
I do not need to see the thumbnail at all.
On these images I do not use any of the qimage tools.
I just need to assign a page size, an image size, set sharpening and print
Thanks
Gary

Oops- I just realized I am using v2018.115
I did not upgrade, as I only use qimage to print and did not use any of the new features.
If an upgrade will solve my issue I will be more than glad to do it.
Thanks again
Gary

. Just poking around, I found this 2018.126 includes improved memory management which enables printing of larger (higher resolution) images. Always good to stay current Might as well get 2019 Fred |

Well I upgraded, but no change.

Still glad I upgraded, great program.

Success!!
I think the upgrade actually fixed the issue. I was choosing a file to send you. I did nothing to the file except rename it. I resaved the file and when qimage built the new thumbnail it was fine.
I tried that with 5 other files- all worked fine. I think I just need to force the updated qimage to rebuild the thumbnails.
Even if I have to do it manually one at a time, no big deal. I only have 15-20 image files large enough to be causing an issue.
Thanks for walking me through this.
Qimage comes through again. Great program
Gary

Quick associated question- as I have more of these large files than I thought.
Is there a way to force qimage to build new thumbnails?
Thanks again
Gary

Yes. You can rebuild thumbs one folder at a time: click "View", "Rebuild Thumbs/Cache". I noticed you said you are enlarging with Gigapixel first. You should try just letting Qimage do the enlargements by just letting Qimage print the originals at 40x60 (or whatever size). Compare the output to the Gigapixel files and if you don't see a difference, you can eliminate the extra time and disk space of using Gigapixel. Gigapixel will really only show a difference in extreme cases. I don't know the resolution of your originals so maybe printing at 40x60 is extreme for you depending on the camera/resolution used, but it might be good to do a test print with Qimage (without Gigapixel) to compare anyway.
Regards,
Mike

Thanks for the quick reply.
I have never compared large printed files. I need to do that.
My native resolution at 40x60 is 130ppi.
I use gigapixel because I tried it once on a file and was amazed at how good it looked blown up- so I just use it.
I do need to step back and let qimage handle this once.
Qimage has never let me down before, will give it a try next time I print that big.
Will let you know
Thanks again
Gary

Starting at 130 PPI, the results will likely be pretty close. Keep in mind that Gigapixel adds some extra sharpening so to compare, you might want to increase the sharpness a bit on Qimage's Printers and Settings tab. You could potentially create smaller test strips (crops) at the same original PPI to test it.
Regards,
Mike
