One even took 4 scans. I was dreading trying to put those together to create a single image.
So I went to my favorite resource: Google.
One of the top hits was Gizmo's Freeware's page on "Best Free Digital Image Stitcher." I liked the price already.
The first entry in the list was Microsoft Image Composite Editor. I had never heard of that.
What is Image Composite Editor?The web page is dated 2008 and the last post on the support forum is from 2011. The downloads are dated 2016 though.
Image Composite Editor (ICE) is an advanced panoramic image stitcher created by the Microsoft Research Interactive Visual Media Group. Given a set of overlapping photographs of a scene shot from a single camera location, the app creates a high-resolution panorama that seamlessly combines the original images. ICE can also create a panorama from a panning video, including stop-motion action overlaid on the background. Finished panoramas can be shared with friends and viewed in 3D by uploading them to the Photosynth web site. Panoramas can also be saved in a wide variety of image formats, including JPEG, TIFF, and Photoshop’s PSD/PSB format, as well as the multiresolution tiled format used by HD View and Deep Zoom.
But it just works!
I downloaded the 64-bit version and installed it on my Windows 10. It stitched my 4 scans together seamlessly, let me rotate easily and then crop. Exporting was one-click (after I added ICE.exe to my Controlled Folder Access).
Where has this program been all my life?
