Which format to use on backdrop?

[lauri.lotvonen]

Hi guys,
What format are you using for your wallpaper on your mig, JPG,GIF, or IFF ?
I'm having some probs with memory (chip) running out when I use pictures size of 1024x768 with 256 colors. From cold boot I have 962 kb of free chip ram without using any wallpaper at all.

Regards,
Lauri

Thanks for the replys everyone.
Once I saw a screenshot here at A.org, where OS 3.9 was just booted and there was 1900> kb of free chip ram left with backdrop of 256 colours and 1024x768 resolution. And using a A1200 for the job. I just wish I could find that pic again .

And I have Fblit, Ftext and IconbeFast installed. If I remeber right they come with AmigaSYS 4.0 installation anyways. I did not mention that earlier, sorry.

I have 1.45MB ChipRAM free after Workbench finishes loading with all its background and task bar images, here it is running several applications with plenty of RAM to spare. Oh, and it responds and refreshes about ten times faster than it does in 256 colour mode.

I'm just amazed how good that looks. My Workbech look's are so crappy that they put all amigas to shame =(. I have to get that configuration running.
Are you using the Scalos for the bars and that "start" thing on the lower left corner?

Just tried the fullpalette and fullpalette.prefs file, but when booted the palette resets to normal WB colors.
How do I save the palette so that the colors remain the same when booted? Tried many options within
FullPalette, and always clicked save ?

There is a kit available which raises the kickstart rom sockets to allow the FastATA and BVision to be used in conjunction.

(I'll take my usual referral fee :-) )

Fantastic matey! That's a great looking classic Workbench - kudos to your mate who developed the pallette presets.

BTW, do you mean Franko when you suggested the kit for Bvision. Because I dont have a PPC card installed.

It's impossible to do this with native Amiga graphics. 1024 x 768 x 8 needs 768 kb of gfx memory. 2 MB - 768 kb = 1.25 MB. That's the absolute maximum you can get. But gfx is not the only thing which needs chip ram. There's also sound, floppy disk and all the stuff in the zero page. It's hardly possible to keep 1 MB free with this high screen resolution.

To have more free chip memory than that, you need a graphics card. The Indivision is not a graphics card. It does not come with its own graphics chips and memory. It just manipulates what the native gfx chips do.

Here's the screenshot I was talking about :

There is no backdrop as I incorrectly remembered, but a whopping 2mb of free chip ram =). Never got that WBAllocFast thingy to work though...Has anyone else here tried that?

[lauri.lotvonen]

With a graphics card you can have almost 2 MB chip-RAM free *without* any patches.

See this for example: http://thomas-rapp.homepage.t-online.de/amiga/screenshot2.jpg

But the native chipset needs at least the displayed bitmap in chip memory.

Sorry, I did not notice that he has/had a graphics card installed.
