Goat 1000 home
Welcome to Goat 1000 - this is where you'll find some of the bits and pieces of software that I cobble together for fun. Please feel free to download them and try them out. All this stuff is freeware, no guarantee that it will do anything, etc. (though if it does fail to do anything, please let me know!)
JPEG Saver 5.1 is a fairly small update to version 5.0, but it does include a couple of important changes. The first of these is the replacement of JasPer with OpenJPEG. These are two different software libraries for handling JPEG 2000 images, which is still a fairly obscure format even after all these years.
If you are using JPEG 2000 images, JPEG Saver should now be able to load them a bit better. OpenJPEG actually supports loading some quite unusual images, but I didn't attempt to support them in JPEG Saver because I would have first had to figure out a way to produce the weird images for testing. So if you have some JPEG 2000 images that JPEG Saver refuses to load, please get in touch and I'll see if I can get them working.
The other quite large change is to how transitions work. It shouldn't really be noticeable in the screensaver, but internally the transitions now use a much more flexible way of deciding what happens when. This should allow for more complicated transitions in future versions.
When I replaced the NSIS installer with a WiX Toolset-built MSI file for version 4.20 of JPEG Saver, I wasn't all that happy with it. It worked fine, it installed and uninstalled the files, but it still had to include the DirectX 9 installer just in case it was installing on a machine that didn't already have it installed. JPEG Saver 5.0 is the first version since 2009 that doesn't need DirectX 9 installed - because it uses DirectX 11 instead.
DirectX 11 should already be installed on Windows 7 and newer, as it is now part of the operating system instead of a separate install. I've tested on 64-bit Windows 10 with Nvidia graphics, 32-bit Windows 10 with AMD graphics, and on a 32-bit Windows 7 virtual machine with no real graphics card at all. JPEG Saver ran without any problems on these, so I'm fairly confident it should run on most configurations.
So what is actually new in this version? Very little, to be honest. I had to rewrite all the 3D rendering code used for the transitions and the real-time items on the main display, but hopefully JPEG Saver shouldn't look or behave much differently to the last DirectX 9 version.
Every now and then I receive an email from someone wanting to do something a bit unusual with SVGGraph. My first response is to try to figure out if it is already possible, and then if it isn't I have to decide if it is something that anyone else will ever want to do. Version 2.27 contains a couple of new features that might not get used very much.
Shapes on line graphs
The first of these new features comes in the form of a pair of new options
for the line and multi-line graphs*. The
line_figure option allows
line graphs to draw shapes, and the
closes the shape. The options don't do much to change how the line graphs are
drawn, they mostly reduce the validation of the data - repeated keys are
allowed and the data will remain in the order it is provided.
