SVGGraph 2.30

This version of SVGGraph adds some more options for drawing things on the graph, building on the existing shape option. The graph below is the example from the shapes page with the new features added.

Shapes with added figures, marker and image

The main difference in this version is the addition of the figure option, which defines named shapes or groups of shapes that can then be used as shapes, in other figures, or as markers on scatter and line graphs. The example graph above has one figure defined and used three times for the red squares with the shaded box over the top.

JPEG Saver 5.2

JPEG Saver 5.2 is one of those versions that doesn't really look any different from the outside. On the inside there have been some important changes, making some existing things more stable and making some things that are still on my to-do list possible.

There are some visible updates - I've made a couple of simple changes in the dialogs that make it a bit easier to use. In the background and style editor dialogs where there are two colours I've added a button in between to swap them over. This also works in the background dialog when using a mode where only one colour is enabled, allowing you to flip between two colour options.

The folders list now shows the number of enabled folders at the top as well as the total number of folders in the list. This is especially useful for me, since I have a long list of folders that I turn on and off for testing different file types, EXIF and IPTC data, automatic rotation, etc.

SVGGraph 2.29

SVGGraph 2.29 is another version that mostly changes thing internally, but there are a few more visible changes too. The most obvious change should be apparent in the example below.

Box division style

Thinking inside the box

Both division_style and subdivision_style (and their _h and _v variants) now support a new style called "box". The Y axis in the bar graph shows how they behave with this new style when the labels are at the division marks, and the X axis shows what happens when the labels are between the marks (usually for bars) - the box is drawn around the label instead of inside it. I have used the subdivision_h option set to 0.5 to enable subdivisions on the X axis so you can see what they look like - they would not normally be displayed.

JPEG Saver 5.1.1

As you can probably guess from the 0.0.1 added to the version number, this is a bugfix release. There are a few annoying bugs fixed in this version though.

First, a crash when using the shape skip option with multiple displays and the secondary displays set to not show any images. That one was easy to fix, and so was a bug preventing the screensaver from automatically progressing through the images when the secondary screens were set to show the previous image.

More complicated was an unrelated but similar bug that sometimes meant that JPEG Saver would not automatically progress through the images, and sometimes not even show the first one.

SVGGraph 2.28

Over the years that I have been working on SVGGraph I have always been grumbling about text. Don't get me wrong - SVG is perfectly capable of displaying text, the problem is that I can never be sure what it is going to look like.

Version 2.28 is an attempt to improve things by using font metrics to calculate the sizes of strings of text more accurately. The two example graphs below demonstrate the difference between the new method and the older method.

Using metrics
no_font_metrics = true

Both graphs are using the "Times New Roman" font, where it is easy to see that "Amanda" is a longer string than "Illicit". The new method is used for the left-hand graph, where it displays the label boxes packed quite closely to the text. The old method is enabled with the new no_font_metrics option, shown in the right-hand graph. The label box is a bit tight around "Amanda", but much too wide for "Illicit". There is more space at the left side of the graph too, because the old method thinks the seven-character string "Illicit" should be longer than the six characters of "Amanda".
