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.
