Good free app for straightening scanned photos
I scan with Irfanview but sometimes the photos are crooked.
I can straighten with Paint.NET but it's a guessing game on the degrees of rotation. Googling I find too many choices, most of which is software I don't have installed (and don't really want to install an entire photo package just to straighten a photo). I guess I'll install "The GIMP", but is there a dedicated freeware straightening program for Windows? --- news://freenews.netfront.net/ - complaints: --- |

|I scan with Irfanview but sometimes the photos are crooked.
| I can straighten with Paint.NET but it's a guessing game on the degrees of | rotation. | It's always going to be a guessing game because there's no reference for what's straight. I have 2 versions of Paint Shop Pro and use v. 5 for rotating. With scans it's often less than 1 degree off. I typically run into it when I scan printed pages to feed to OCR software. (With photos 1 degree off is usually not so noticeable.) You really need a graphic editor for that. First because most free software doesn't provide incremental rotation. (Like IrfavView, which just provides a 90 degree option.) But also because once you rotate it you need to clean up the edges so that you still have a rectangular image. In other words, the problem is not the software. It's just a tricky job getting an image perfectly straight. Why wouldn't you want to have a graphic editor, anyway? If Paint.Net isn't adequate you might look into Paint Shop Pro. You can usually get it for less than $50, with functionality comparable to Photoshop, which is far more expensive. There are dozens of partially functional graphic programs. They used to be given away with printers and scanners. But those are generally limited to basic operations. Incremental rotation is not basic in that it's not available as a Windows function, so it requires complex code to do it. Rotating 90 degrees, on the other hand, is easy. I originally paid $100 for PSP5 and $50 for PSP 16. Oldapps.com has older copies for download. V 5.03 is called psp503ev.exe. Maybe that's only an "evaluation" copy? I don't know. I know that some versions were given away free with modems and such. So you may be able to get it free. The nice thing about the older versions is that most basic functions are there but the program is small and simple. (PSP5 was written for Win9x, but runs fine on NT systems.) If you don't need professional editing functions, like turning an average model into a more shapely woman with perfect skin or working with RAW images, then you don't need the newer, bloated versions. (I mainly use PSP 16 for advanced sharpening functions and working with RAW format. For web graphics, simple image editing and work diagrams, PSP5 is quicker and easier to use.) GIMP is a long-standing disappointment. It's over 20 years old now and always under construction. Last version I tried (2.8?) still couldn't even handle a proper MDI (multiple document interface) window. The toolbars all float around. It's ridiculous. And like most other such software these days, it's bloated. But for anyone who needs the functionality and has more patience than money, it might be worthwhile. |

In Windows 10, there is a program called Photos and it can do wonders but some idiots and nuteers aren't using Windows 10 because that Canadian "Small Boys Abuser" has told them that Microsoft is spying on users. In Win 10 when you launch Photos, you will get something like this: Photos-Rotate https://s31.postimg.org/yxftv54q3/2016_07_15_2117.png The above picture is the toolbar from which you can rotate your image and it is free to use. -- With over 350 million devices now running Windows 10, customer satisfaction is higher than any previous version of windows. |

As long as the error is systematic, follows some rule of math, you can "attempt" or "test" transforms until you find the correct one by accident. So if you don't know what fisheye effect is or don't know what barrel distortion is, you can always try the tool until you get a decent match. https://helpx.adobe.com/photoshop/us...ion-noise.html ******* Some scanners rotate the scanned result for you, in the plugin. (My scanner is too old to be this fancy - all mine has is antialiasing for medias printed with half-tone dots.) ******* Some things cannot be corrected, such as scans from plain paper, where various parts of the paper shrunk or stretched in a non-systematic way. Nobody offers a transform for that. ******* If the purpose of rotating multiple scanner pages, is as a first step for gluing them together in a panorama, you can use Microsoft ICE to do all the gluing for you. https://en.wikipedia.org/wiki/Micros...mposite_Editor After the panorama is in hand, you can apply one final global rotate, to give the best overall alignment. ******* And the GIMP may have something - but it might not be in the menu already. Apparently the effort was nearly lost, and this person saved the plugin for later. Deskew attempts to align to the axis, by noting features that seem to be linearly arranged. https://github.com/prokoudine/gimp-deskew-plugin Paul |

I installed the latest Gimp but it is crashing every time. Maybe it's a GTK thing? So I'm installing The Gimp from 2007 now, and I have an archive from 2011 (that's how often I use it) that I can try also. I originally paid $100 for PSP5 and $50 for PSP 16.

The nice thing about the older versions is that most basic functions are there but the program is small and simple. (PSP5 was written for Win9x, but runs fine on NT systems.) Yup. In general, there's little that's very useful in the newer versions of much of the popular software. The basics are all I need, which is why the 2007 version of The Gimp may serve my needs. If you don't need professional editing functions, like turning an average model into a more shapely woman with perfect skin or working with RAW images, then you don't need the newer, bloated versions.

And like most other such software these days, it's bloated. But for anyone who needs the functionality and has more patience than money, it might be worthwhile. The latest version crashed every time on me. I have 2.6.6 from 2009 in my archive. And I have 2.4.2 from 2007. And a version from 2013. Hopefully one of them will work. --- news://freenews.netfront.net/ - complaints: --- |
