JPEG Saver 4.0

JPEG Saver 4.0 is a new version of JPEG Saver with all old transitions ripped out and replaced with new DirectX 9 Direct3D-based transitions. This means all the complicated work will be done by the graphics card, instead of the old way where the CPU had to do all the work.

The end result of this will be smoother transitions and the ability to do things that would have been too slow and ugly the old way. It also means the real-time updating clock can stay on screen during the transitions instead of stopping for the duration.

The configuration of JPEG Saver 4.0 is backwards-compatible with version 3.*, so you can install 4.0 over the top of 3.6, or 3.6 over the top of 4.0 if you decide to go back to the previous version. The config and cache files from the previously installed version can be used without modification.

Final release of version 4.0 - 30/01/2010

Very little has changed in the final release version, but the installer has been improved to check if the required DirectX libraries are installed already.

Preview release 3a - 20/01/2010

There were a couple of bugs in preview 3, one of which could cause JPEG Saver to crash, so I've replaced it with preview 3a. The "Explode" and "Implode" transitions had a memory allocation problem and the dimmer would cause the non-primary screen to go black under some circumstances.

Preview release 3 - 17/01/2010

Preview release 3 contains these changes from the second preview:

• Fixed dimmer for non-primary monitors;
• Transitions that would have crashed before should now disable themselves instead;
• Added "Spiral" and "Tune in" transitions;
• Split "Zoom fade" transition into old and new types;
• Made several of the transitions smoother;
• Upgraded libpng to 1.4;
• Fixed several small bugs.

Preview release 2 - 05/01/2010

Preview release 2 contains these changes from the first preview:

• Some small bugfixes and improvements;
• Basic multi-monitor support is back;
• The gamma and dimmer controls are now working again (though only on the primary display for now);
• Per-colour component gamma adjustment controls have been added to the gamma/dimmer dialog;
• The main "Navigation" option has been renamed to "Interactive" because many of the keys available now are nothing to do with navigation;
• New gamma adjustment keys have been added to adjust the gamma while the screen saver is active:
  
  

  Numpad +	Increase gamma
  Numpad -	Decrease gamma
  Numpad 7	Increase red
  Numpad 8	Increase green
  Numpad 9	Increase blue
  Numpad 1	Decrease red
  Numpad 2	Decrease green
  Numpad 3	Decrease blue
  Numpad .	Revert to saved values
  Numpad *	Save current values to config file

  
  (I'm planning to add a new page listing all the keys available at some point)

Please read this before downloading!

This version uses DirectX 9 - so you must have DirectX 9 installed to use it! If your computer doesn't support DirectX 9, then this version of JPEG Saver is not for you.

*** If you have DirectX 10 or DirectX 11 installed, that still doesn't mean you have all the DirectX 9 libraries installed! ***

The JPEG Saver 4.0 installer comes with Microsoft's DirectX web installer, so you can install or update your version of DirectX from the installer.

Alternatively, you can download the full installer or updates directly from the Microsoft Download Center.

DirectX cannot be uninstalled, so I recommend setting a restore point before installing it.

JPEG Saver 4.0 requires the main d3d9.dll and d3dx9.dll libraries.

Windows 7 users!

Windows 7 comes with DirectX 11, but it does not include all the DirectX 9 libraries required to run JPEG Saver. Please update your DirectX 9 installation!

Bugs?

I expect there are still bugs in this version - if you find any, please let me know and I'll do my best to fix them.

Before you tell me about missing transitions, please note that not all of the transitions from the 3.x version have been rewritten to work with the new rendering method; I expect I'll get around to them eventually.

If you spot anything else that appears to be broken, please contact me with whatever details you think will be useful by emailing graham (at) goat1000.com
