JPEG Saver 5.36
This time I've made some changes that should be useful for at least some users. Or if not useful, they may at least be fun to try out.
In, out, shake it all about
I think someone once asked me to add zoom and pan controls to JPEG Saver, but at the time it wasn't something I thought would be easy or appropriate. Having already added rotation and flipping controls, zooming and panning controls now seem like obvious additions.
This time around I have implemented the controls for both images and videos. I was going to use the numeric keypad for the keyboard shortcuts, but I have already used that for other functions - so I've used a combination of the Control key and the WASD keys commonly used in games for the panning, with the 'E' key to zoom in and 'Q' key to zoom out.
JPEG Saver 5.35.1
I haven't found time to do the stuff I had planned for version 5.36, so here is 5.35.1, a small update that fills in a software pothole I left in version 5.35.
Let's go round again
I added support for flipping and rotating images in version 5.35, but since video works very differently I didn't get it working there. This version fixes that.
There were so many possible ways I could have got this working that I probably spent more time thinking about which was best than actually writing the code to do it.
JPEG Saver 5.35
I took a long, hard look at my to-do list after releasing the last version. A lot of the things on it now are quite complicated and would justify a version 6 of JPEG Saver, but there are still some things that I can do without too much trouble...
Flipping HEIC again
I've used the pun before, but this time it is because I have added keyboard shortcuts for flipping and rotating the main inage. This works by reloading the image and overriding the flipping and rotation setting that would normally come from the EXIF orientation field.
That means it could be slow if your images are large, but you will not lose resolution when the image is repeatedly switched between portrait and landscape.
JPEG Saver 5.34
Another new version of JPEG Saver without much new stuff in it, but it does have a couple of useful features added.
AVIF by magic...
Adding AVIF image support was pretty simple once I had figured out how to compile dav1d - the libheif library does all the hard work, and JPEG Saver was already using it for HEIC images.
Open with...
The interactive options dialog now has a new button in it called “Edit apps…” which lets you set up applications that will be used for opening files from the screensaver. If you don't set up any applications, then JPEG Saver will continue opening files using the default Windows applications the same way it did before.
JPEG Saver 5.33.1
Here's a quick update to fix the false positives that some virus scanners were reporting for the last couple of versions. I wasn't expecting it to be this easy to fix, which is why this update is coming so soon after 5.33.
Failure to launch
The virus warnings were not caused by the main JPEG Saver screensaver, but by the small utility I included for launching it in desktop helper mode. I've fixed it by removing the utility - the installer now installs a second copy of JPEG Saver that checks its own filename and uses that to decide whether to run as a screensaver or the desktop helper.
Why the trojan identification?
As far as I can make out, the launcher is flagged as a trojan because it starts the screensaver and passes in an argument.
