Hi, Can anyone point me to some good or interesting 64 color backdrops.  I see lots of nice Workbench images with cool backdrops but I have no idea where to look for any.

Well, I would say get ahold of some nice 24-bit bitmaps and then use a copy of AdPro to reduce them down to 64 colors... but given that other thread on that software going on right now, would that just be trolling?  LOL.  :lol:

TL;DR.  ImageFX or other software can do that for you as well.  Heck, I used to have the Rebel 16-color palette mapped in Photoshop on my PC, down to the exact RGB values, and I'd scale images down for my Amiga that way.  :)

Crop the image to the exact resolution of your Workbench prior to setting it. Color reduction is performed by datatypes, try upgrading to the WarpDT's for better performance. Also check your palette, many optimizations can be made there - e.g., set the image to use the exact same colors as your Workbench. Recommend reading things like mfilos's guide to the Rebel palette (linked to above) for a better understanding. :)

Two other tips:  If you're not already using Peter K.'s icon library, you should:  http://aminet.net/package/util/libs/IconLib_46.4

A new version of it was just uploaded a couple days ago.  This will provide you much faster icon rendering and more accurate color reduction, especially if you're using something like 3.9 GlowIcons or Ken's Icons.

And I assume you know about these options, right?:

Right, that is what I just did.  I have an issue not hard to imagine
to know or not know which software is currently supported and
which is not.  Took a minute to realized that it was support software

Totally understandable!  The person who wrote those DT's (and other software) is still active in the Amiga community.

In the past I've registered other software, not necessarily because I expected the author to magically come back, but only because it felt right - for example if it was something that I'd pirated many years ago.

In any case, WarpDT's are great and well worth supporting.  Cheers!  :)
