JPEG Saver 5.8

So here it is, after years of looking at the word “video” on the to-do list and deciding it sounded too much like hard work: version 5.8.

Video Killed the Radio Star

Yes, version 5.8 does add support for loading and playing videos. The main tab in the config dialog has a checkbox to enable loading video files and a button to take you to a dialog to configure what happens next.

If you just enable the main video option and disable the others, JPEG Saver will load the first frame of the video and use it like any other image type. If all your videos fade in from black that could be a bit boring, so I might have to improve that in the future.

JPEG Saver 5.7.1

Just a quick bugfix release for JPEG Saver this time, fixing some code that I added in version 5.7 that interacted with some other new code and meant JPEG Saver could crash.

The crashing was caused by JPEG Saver attempting to load images that don't exist (because of the new option that keeps the old database for a while) and then trying to display the size of the non-existent file. The file size token code was using a function that throws an exception when the file doesn't exist, which made JPEG Saver crash. I've replaced it with some code that won't crash, just return a file size of 0.

Another minor update is to the file size (again) and the two memory size tokens from the process info item. They were displaying some extra trailing spaces after the text, so I have cleaned that up. The only other change in this version is updating the WebP library to version 1.0.3.

JPEG Saver 5.7

JPEG Saver 5.7 is another one of those releases that doesn't look like it changes much. Sorry. But I have changed quite a bit.

Finding images…

Most of the changes in this version are related to how JPEG Saver finds the images to display. The most substantial change is a whole new way of finding the images, with the process split into two threads: one to find the list of files and another to add the images to the database. This change should make the process quite a bit faster - it certainly did in my tests.

The second change is to the “Finding images” message, this time updating the status text with what JPEG Saver is actually doing. There are several very short steps in the process that happen before the serious work begins that you probably won't see, but you are fairly likely to see a status of “Checking for updated folders” if you have a reasonable number of images and folders to scan. After that step the status is replaced with “Found” and the number of images that have been discovered in this run.

JPEG Saver 5.6.1

It's time for a bugfix release - I don't know how many people are being affected by these bugs, but some of them could be really frustrating.

The first bug is the most serious, because it means JPEG Saver could sit there doing nothing until you came along and poked it. That's not good for a screensaver. This was because JPEG Saver could get confused about whether a transition had completed or not and never move onto the next image. So this is fixed now.

Next is the most obvious update in this version, to the “Finding images…” text. Until now it would fade in and out telling you that it was looking for images to display, but if you have a lot of images it could be doing that for quite a while. Now it displays the number of images that it has found in the current run and is updating in its database, which could be all of them or just some that needed rescanning. If you have a lot of images spread over many folders the number might stay at 0 for a while because of the way it checks for new images. I'm planning to do some more work on the image finder in version 5.7, so I will improve this display a bit when I am working on that.

SVGGraph 3.5

SVGGraph 3.5 does the stuff that I was trying to do when I ended up adding support for shadows. I'm hoping this is a change that people will find quite useful.

Colour filters

The main change is the addition of support for colour filters. What this means is that you can choose a colour and modify it using a filter to get a different shade or hue. This is not easy to explain, so here's an example:

Colour filters example

These bars are all using the main colour “red”, but with different colour filters applied. In this case the “hue” filter is used to change the colour quite a lot. The actual array of colours used is shown below.
