JPEG Saver 4.17
There isn't as much new stuff in JPEG Saver 4.17 as I had planned but I wanted to release it now because it fixes a couple of bugs, one of which was really hard to find.
The main change in this version is the addition of filter presets in the filters dialog. I've compiled in a few that I think will be useful, but you can also add your own, modify the defaults, and mix them together using the “Insert” option. If you have any really good ideas for filters please let me know and I can add them into a future version.
I'm still planning to add filtering by tags/keywords, but that was too complicated to make it into this version.
SVGGraph 2.21
This is a relatively small update to SVGGraph, mainly because I'm trying to release updates more often instead of saving up a bunch of changes to release all at once. So this version is centred around the best-fit or trend lines.
Until now these lines were only supported by the scatter graphs, but now the
line graphs support them too. The example graph above has four datasets and four
best-fit lines, though the green and blue datasets are using the new
best_fit_range and best_fit_project options. The
best_fit_range option lets you specify the range of values to be
used in calculating the angle of the best-fit line, and
best_fit_project tells SVGGraph which bits of the line outside the
range to draw.
By default the projected part of the line is drawn with a 4-pixel dash pattern,
but there are best_fit_project_dash, best_fit_project_colour,
best_fit_project_width and best_fit_project_opacity
options for changing its appearance. There is some more explanation on the
scatter graphs page.
JPEG Saver 4.16
JPEG Saver 4.16 is mainly a bugfix release, but there is one fairly major change that I think justifies version number 4.16 instead of 4.15.1.
First things first, the bug that is fixed in this version took about a month of confusion, testing, updates, more testing, rinse, repeat, etcetera between the user who reported the problem and myself before we found where the bug was and how to fix it. The problem was that the colours on his PCs were messed up - the red and blue components of the images and almost everything else on the screen were swapped. This happened overnight after a Windows update, which didn't help. In the end I traced it back to a problem with a DirectX texture, so this version fixes that and the colours are back to normal. Phew.
The one new feature in this version starts with an extra option in the installer marked “Windows Explorer integration”. What this does is add an extra entry to the Windows Explorer folders right-click context menu, named “JPEG Saver slideshow”. Choosing this option will start up JPEG Saver loading images from the selected folder, using your current config file but without its folders, filters or aspect ratio option. There are a couple of extra options in the “Interactive options” dialog so you can choose whether to use sequential mode and random start or not when using the slideshow. The selected folder is scanned recursively for images, so don't be surprised if it spends a long time “Finding images…” when you point it at your Program Files folder.
TagCanvas 2.9
TagCanvas 2.9 adds a couple of new options, adds some extra ways to colour
the highlight and adds in missing support for the pulsate option.
The cloud above demonstrates a couple of the new options added in this version.
First, when you move the pointer of a tag you will see the highlight outline is
displayed using “marching ants”. This is configured using the new
outlineDash, outlineDashSpace and
outlineDashSpeed options. The first one sets the size of the dashes
in pixels, outlineDashSpace allows you to set a different sized space
in between the dashes, and outlineDashSpeed lets you specify how
fast the dashes move. The example cloud is using a dash size of 10 and a speed
of 4. The default speed is 1 (which is quite slow) and you can also use negative
values to make the dashes move in the opposite direction.
You may also have noticed that the highlight colour is not the same for all
the tags in the example cloud above. Version 2.9 of TagCanvas has three ways to
set the highlight colour for individual tags - the example is using the
outlineColour option set to “tag”, which tells TagCanvas
to get the highlight colour from the text of the tag's <a>
links. It also supports a value of “tagbg” to use the background
colour from the links instead. The third option for setting the highlight colour
individually is to set the weightMode to “outline”,
which colours the highlight using a weight gradient in the same way that the
“colour” weight mode sets the tag text colour according to its
weight.
SVGGraph 2.20.1
SVGGraph 2.20.1 is mainly a bugfix release, though I've fitted in a couple of new options as well. The main bug fixed in this version is in the calculation of unit values for shapes (and custom labels) when the graph axes are not in the bottom left of the graph. This happens when you have negative values or adjust the axis minimum value.
The second bug is very minor - passing an array containing a single value as a colour was being parsed as a gradient. This caused an error because there were too few colours, so now SVGGraph will just use the single colour.
The first of the new options is bar_width_min, which gives you a
bit more control over the automatic bar sizing. Up until now bars have always
had a minimum width of one pixel, and the option will continue to use a value
of 1 by default.
