JPEG Saver 4.9
The biggest change in this version of JPEG Saver is the addition of support for loading files in the WebP image format. In case you haven't heard of it before, it's a bit like the JPEG format in that it supports lossy compression, and a bit like PNG in that it also supports lossless compression and alpha channels.
Loading WebP images is supported for the main image, background images and logo items (with alpha channel transparency). The WebP format supports EXIF and other metadata, but I have not yet attempted to add support for loading it into JPEG Saver. Expect this to work in a future version.
Other changes in this version are an extra slider in the logo item dialog for setting an alpha blending value, an extra checkbox on the background tab for maintaining the aspect ratio of images when scaled to fit the screen, and four new transitions: “Doors”, “Wall tiles”, “Fold” and “Unfold”.
SVGGraph 2.12
The new version of SVGGraph doesn't contain any really big changes, but it does have several new options for how the graphs should look. I've tried to illustrate most of the new options on the example graph below.
Unless you are profoundly colour-blind, the most obvious new feature on this
graph should be the addition of green stripes - this is enabled with the
grid_back_stripe option and the colour can be set using
grid_back_stripe_colour. The stripes are drawn from the major grid
lines on the Y-axis.
The next change is on the Y-axis, where it is using a logarithmic scale. This is
enabled with the log_axis_y option, and the base for the logarithm
can be set using log_axis_y_base. I've added some extra documentation
about using the log scale on the axis
and grid options page.
TagCanvas 2.1.2
A small update to TagCanvas this time, all it does is scale the cursor position in browser or screen pixels to match the pixels in the canvas. That doesn't sound very interesting, but it means that using CSS to change the size of the canvas will no longer mean that the mouse doesn't select the tags properly.
This does not mean that you can use CSS to set the canvas size without using the
canvas element's width and height attributes - they
are still required to set up the size of the canvas in pixels. If you use CSS to
change the size of a canvas, it will use the width and height given by these
attributes internally.
This means that increasing the size of a canvas using CSS is likely to cause aliasing, so try to set the width and height attributes as close to the actual size as possible or it might not look very good.
JPEG Saver 4.8.1
There are a few bugs fixed in this new version of JPEG Saver. A couple of them were small issues I found myself while writing the new online JPEG Saver documentation, but the worst was an intermittent crashing that didn't seem to be caused by any particular image or option. In the end I had to compile in support for creating a mini-dump when JPEG Saver crashes so I could find out where the crash happened.
The crash dump support is still compiled in to version 4.8.1 - if you think JPEG Saver is crashing, please contact me and I'll do my best to find and fix the problem. Crash dumps are only created when you set an option in the config file, otherwise JPEG Saver will try to crash quietly and leave you alone.
Other changes in this version are added support for loading CMYK JPEG images (very unusual - I've only found one in the time I've been working on JPEG Saver), some very simple support for using the Windows Pictures library folder when there are no folders already set up, and some improvements in the dialogs to prevent setting options that won't work. As usual, the new version is available from the downloads page.
SVGGraph 2.11
This new version of SVGGraph contains some quite major changes, mainly to support a new method of specifying the data to show on the graphs. I've called the new data format “structured data” and you can read about it on the new structured data page.
The main advantage of the new structured data format is that it allows for bundling other information along with the data fields. At the moment this is limited to tooltips, colours, labels, links and the text shown on the X-axis, but I plan to add more support in future.
