What is the best Snapshot for Radeon card

Postby Kroll » Mon Jun 05, 2017 7:59 pm

Hi,

I wolud like ask about the best snapshot. I wolud like use with this configuration
Atari Falcon 060/CTPCI/Radeon, system is MiNT + Xaaes + Thing (Teradesk) with 32 bits graphics (!!).

I thought the best will be xaesnap.prg, I run it at system startup (in the xaaes.cnf file), After pressing the ctrl + alt + D key combination appears window with Block, Full screen, Top window, Cancel, and create file on u: \ram snap_000.tga, but how do I open it in Zview, this picture is all black. does not support 32 bit graphics ?

So I have a question if some other snapshot is working because you can set the path to an external snapshot or use it as an accessory

What do you recommend?

If I remember correctly, JML Snap works fine with supervidel: http://milan.kovac.cc/atari/software/?f ... L_SNAP.FTP

Unfortunately, I checked both Falcon and graphics card, as well as firebee, just after selecting the fragments from which to do the screenshots appears information "unknown hardware graphic".

Yes you are right fvdisnap works on Falcon with Radeon (on firebee too), but it is runs only as accessory, and I am still looking for snapshot work as external program like xaaesnap.prg

Helmut the XaAES developer has a XaAES Snapshot GIF tool that works great ...

I've uploaded it here:

http://hek.bplaced.net/atari/snapshot.gz

It has issues with fVDI in 8-bit: all colours > 16 are black, and with the Matrix-card: some colours are just wrong. I don't do anything on it currently. In xaaes.cnf say: snapshot=<full path>\snapshot. Should work like xaaesnap, output goes to the clipboard.

Hi, thank you I have just test it, however, I have my comments
I tested Atari Falcon + CTPCI + Radeon 32 bit graphics with NVDI, behaving like xaaesnap.prg. When I press the CTRL+ALT+D key, the window will pop up. Yes it is working, when you save the mouse cursor disappears and you have to wait for it to appear (also toggled sound) depending on the size of the block or Full screen a little it takes

Also, you are right that some colors are wrong :(

The gif-file has at most an 8-bit depth, and therefore the program must find a palette containing the most common colours if the source has a higher depth. Then it tries to map the other colours to the nearest ones in the palette. This might not be 100% perfect, and if you snap a natural image you may observe strange things. Good enough for documentation though ;) Also this process might need some time, but on aranym it's still fast enough. Of course a 32-bit output-format would be more suitable in your case.
The mouse is off to not have it in the snapshot, sound I don't know.

Thank you very much, You are absolutely right, so I will have to use snapshots as an accessory and the best one will be fvdisnap or jpegsnap.

How does it know the nearest colours ?
Isn't it a LUT ?

I adds the absolute differences of r,g,b, and looks for the one in the palette with the smallest difference. Surely not the best solution. LUT is the palette, isn't it?

Wow... neat, I never figure out how to approximate match a colour.
IDK i thought the 256 colours were based on LUT.

With MyAES CTRL + alt + D create on the version you have scrap.tga a true color TGA uncompressed, in any resolution (even in Black and White)

Guess the "direction" needs to be taken into account, not only the delta: You can't map for example (0,0,3) to (0,3,0).

graftool shows that it's possible without any blurs: Run in 8-bit and load a 24-bit image, it has to do the same job as my snapshot-program.

Wow, I did not know that in MyAES, this also works with key kombination CTRL + ALT + D, I did not find anything in the file myaes.cnf, which uses its own snapshot ?
Works great, super :)

Great stuff.
When to google a bit, just out of interest , not that I am doing any graphics stuff. Seems there are quite a lot of information on how to do this. But I am sure there already some implementation in Z-tools. Lonny mentioned that every graphics inside the Zorro's Codec are in 24 bits, and so Zorro must have an algo to make it to 8 bits etc for the Atari.

Yes this fuly internal, MyAES is based on screen.ldg (to reduce space and speed up I include it in MyAES on the last version) that is able to transform 24bits RGB to any screen video format and from any video format to 24 bits (the first affirmation is true for more than 15 years but the second as it was not tested not work in all case, I have fix a lot of format on your last version with Guillaume Tello and his exotic video card!). TGA save is too a function of screen.ldg, so do a snapshot is quite very easy to only some lines!

I'm very confident with this feature, if you add shift key, the mouse is removed for screenshot
