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.
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:
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.
So it's a new year and a new version of JPEG Saver. It's also Blue Monday today, apparently, but all that means to me is the New Order song that I can't seem to separate from that other New Order song. You know - the one with the weird video. But anyway…
The most significant and obvious update in this version is how the speed of transitions is controlled. In earlier versions the speed slider on the main config dialog had five settings, going from half-speed up to double-speed. Now the slider uses percentages for the speed, and ranges from 25% up to 300%. There is a blue bar on the slider that shows the old range of values, and the slider can be adjusted in 5% increments.
Above the slider is a new checkbox marked “Random” which enables using a random speed for each transition. By that I mean each image change gets its own random speed, not that each named transition gets its own random speed. Setting the speed of each named transition individually is still on the to-do list, but you can't do that yet.
Welcome to the end of year to-do list fix fest, where I've gone through the to-do list for SVGGraph and tried to do as many as possible. This might seem like a bit of a random way to get things done, but it means I crossed off an item that has been there since early 2016 so I would call it a win.
The Coming of Shadows
The first of the new options adds support for displaying drop shadows on the graph:
This is actually my second attempt at getting shadows working. The first time
I tried duplicating the shapes and changing the colours, but it didn't work at
all well. This time I have used an SVG
<filter> element to
copy, desaturate, offset and blur the graph features to make the shadow, which
gives a simple and consistent result for all graph types. The downside is that
SVG filters might not be very well supported by some SVG to PDF libraries, so
they might not show up if you try converting to PDF.
TrayBlank 1.10 is a small update that does something really useful. Well, I will find it useful anyway. I'm not really sure if anyone else finds TrayBlank useful at all. Maybe I'm just making it less useless.
Up until now TrayBlank's progress bar has shown the progress until the screen saver starts. Unfortunately, it didn't take one important thing into consideration - the power management settings. I kept seeing the progress bar chugging along before the screen went black as the monitor switched off without the screen saver starting up.
The update adds in the monitor power-off time to the icon tooltip, and also changes the progress bar when the screen saver is going to be preempted by the power management settings. Instead of the solid bar that gradually changes from blue to red, the bar will be a sort-of zig-zag line in yellow. I tried quite a few shapes and colour combinations, but this seemed like the one that was most obviously different from the normal progress bar.
SVGGraph 3.3 is another update that looks like it has very little in it. Here's the most obvious change:
The ArrayGraph is a new graph type that uses subgraphs to split datasets out and draw multiple graphs on one document. It is a bit limited at the moment, but I thought now would be a good time to release it and see about improving it later. Some details of the ArrayGraph and how to use it have been added to the other graphs page.
