SVGGraph 2.24
SVGGraph 2.24 is one of those releases that doesn't look like much, but took
ages anyway. The most obvious change in this version is the addition of the
SemiDonutGraph graph type, which looks like this:
It's just half a donut graph, really. The code of the SemiDonutGraph is very
simple and mostly relies upon setting a new option added for all pie graphs
called end_angle, which tells SVGGraph where the circle should
end. There is another option to go with it, slice_fit which is
enabled by default and positions the partial pie graph so that it is scaled to
fit the available space.
CRCDropper 3.5
So it's a new year, and the first new release of the year is... CRCDropper 3.5. The previous version of CRCDropper was released in 2012, so this update might surprise some people. I'm surprised it has been nearly five years since the last time I worked on CRCDropper, but here we are.
Anyway, what does this new version do? The main change is that version 3.5 has a config file: a text file that is stored in the same folder as the CRCDropper executable file and uses the same format and code as used by JPEG Saver. The config file stores the window position and size, the selected hash algorithm and the value of the new options.
The new options are “Stay on top” to keep the CRCDropper window
above other windows, and “Lower case” to output the hash values
using lower case 'a' to 'f' instead of 'A'
to 'F'.
JPEG Saver 4.18
Version 4.18 of JPEG Saver does not contain many visible changes, but it does have a couple of updates that I have been promising for quite a long time.
But first, something I have removed from this version is support for Windows XP. Microsoft stopped supporting XP a couple of years ago, so writing software that supports it using Microsoft development tools is becoming more and more difficult. So I decided it was time to give up, and set the compiler to target Windows 7 as the minimum version supported. Checking the Goat 1000 web stats showed that I had even fewer visitors using Vista than XP, so Windows 7 it is.
The first of the promised changes is filtering by tag. The tags JPEG Saver uses are scanned from the EXIF and IPTC keywords fields in the image files at the same time as the width and height, then stored in the database. So if you intend to try filtering by tag, I recommend using the “File » Clear database” option to force a rescan beforehand.
SVGGraph 2.23.1
This version of SVGGraph mainly fixes a few bugs, but I have added one new option too. It doesn't do anything visual, so there is no example graph to show for it.
The new option is datetime_key_format, for use with the
datetime_keys option added in version 2.23. This new option allows
you to specify a format for parsing your keys instead of relying on PHP
recognising the format. The format string is described on this PHP manual page:
DateTime::createFromFormat.
The first of the bugs fixed in this version is also related to the
datetime_keys option, solving a nasty error when using multiple
dataset graphs without structured data.
SVGGraph 2.23
There are a couple of bug fixes in SVGGraph 2.23, but the main change in this version is the addition of a date/time axis. Here's an example:
For comparison, the same data without the date/time axis enabled is shown here:
The graph without the date/time axis has spread the values out evenly, not making any use of the date and time information. You could still use a callback function to reformat the axis text if this is the way you want to present your data.
