Fix wrong Photo rotation problems in Windows Explorer

Microsoft finally released a fix for a rotation issue. Indeed, you could have experienced with PhotoLikr and preview window of Light Image Resizer such problem, while the final output is correctly processed. The easiest way to check if you have the orientation problem is to check if a portrait photography has been wrongly rotated. CR2, CR3, RAF, or any raw digital camera format could be impacted.

After the fix, you still need to run the disk cleanup tool. Use the last option of the files to remove : thumbnails. It will force the thumbnails in windows explorer to be cached again.

You can find information about the fixes in the Microsoft’s Blog

KB5046740 changelog 14 november 2024

2 mentions are interesting :

[RAW format images] Fixed: They show in the wrong orientation.
[JPG files] Fixed: You cannot use an API to find rotation information. 

So maybe the problem wasn’t the update of the RAW Camera update but the operating system files themselves who causes wrong rotation in windows explorer.

Run Windows Update or refer to the documentation.

Obviousidea software and antivirus

Fabrice greencloud printer driver, Light Image Resizer, ObviousIdea , , , , , , ,

Since this morning, several users reported a virus issue with GreenCloud Printer. After investigations and the first reports, it is a false alarm from some antivirus solutions, and the main one seems to be BitDefender.

What is a antivirus False positive ?

Security software sometimes unintentionally identify a program or file as harmful if it has code or behavior that resembles known harmful programs. This is known as a False Positive. A False positive means the antivirus wrongly identify the app as a virus.

Action from Obviousidea about false positive

We reported the false alarm. In the meantime, please don’t deinstall / reinstall the GreenCloud Printer package, as it won’t solve the problem. The only solution is to turn off the antivirus or flag it as safe. You can also report the false alarm at : Bitdefender false positive report . The BitDefender form is weird and won’t confirm by email if the ticket is created. You can contact support of Bitdefender, this page contains the list of the phone numbers.

Another method is to “restore” the binary GCPrinter.exe, in notification, watch the history and find the entry about the software infected. Then Restore the program.

We are sorry for the inconvenience. Especially because the latest version of GreenCloud Printer hasn’t been updated since a few months. It may happen also with Light Image Resizer. To fight against virus, we are using VirusTotal, a well known service in the industry to check URLs and setup package available in our download page.

Here the link of the VirusTotal report for GreenCloud Printer :
november 11th, 2024 : 10/73 vendors are reporting a problem
november 12th, 2024 : 4/73 vendors are reporting a problem
november 13th, 2024 : 2/73 vendors are reporting a problem
november 14th, 2024 : 1/73 vendors are reporting a problem ( https://www.deepinstinct.com/ didn’t reply to our report )
november 19th, 2024 : webroot solution was not in the virustotal report but cause issues, it’s fixed now.

How to report a false positive ?

Don’t hesitate to contact Obviousidea, to report any issue with antivirus, it’s the best and safest way to let us know and report and investigate the problem.

there is no rule to report a false positive you need to fill a form ( when it works ) or contact by email one by one the antivirus vendor. This list from VirusTotal can save a lot of time.

Fabrice Light Image Resizer, ObviousIdea , , , , , , , ,

Spoiler alert, the new Light Image Resizer version 7.1 has a native read and write support for JPEG XL / JXL, but also improvements for the AVIF format.
Both JPEG XL and AVIF are performant for compression and quality. In WordPress these formats are considered as modern. Apple is supporting JPEG XL in Mac OS, and you can create .DNG that LIR 7.1 supports.

Download Light Image Resizer 7.1, it’s a free update for users with a valid v7 license key.

About Light Image Resizer 7.1

The new version is a cumulative update of customers feedback and the support of modern formats has changed the internal engine with the introduction of the Imagemagick Plugin. LIR7 could support more formats in the future, as soon as a WIC codec extention is available.
