I like the way Qimage interpolates small files to larger files.  I have a photo that I want to give to someone that she can print herself.  My original file is just too small to make as big as she needs it.  (The picture I printed and that she saw and wanted to make a larger version of was already cropped quite a bit.)  I don't have the capability to print 16 X 20 on my printer, so I'm willing to just give her the file.

Is there a way I can have Qimage interpolate my file and then save it to a flash drive to give to someone?

There are several ways to do this.  You could just increase the resolution in the editor and save.  But in this case, you might want to print to file so you get Qimage's interpolation and sharpening.  On the Printers and Settings tab, you can drop down printer and select "Print to file".  Then set up your page to 16x20 with whatever PPI you want: in this case, 300 should be enough.  Add your image to the page with "Fit to Page" size so it covers the whole 16x20 page, and click the print button.  The resulting "printed" file will be 16x20 at 300 PPI and Qimage will have applied the same process to the file (interpolation and sharpening) as it would if you had printed to a printer.  You can then send that file.

There's another way to do this. You could tell her about this fantastic printing program that doesn't cost an arm and a leg, that would improve everything she prints, handling color management and printer settings better than anything out there. IMO, it should be illegal to own a printer without it. Just saying.

She's not a photographer nor a printer.  She just liked my photo.
