Hollywood forums

The instruction: @BGPIC 1, "BG.png", {LoadAlpha = True} with AROS don't show the brush with alpha transparent channel, but I don't know if the problem is in Hollywood or in AROS, the result for example with the Apple example is show a black background behind the Apple.

Operating systems must support alpha transparent windows for this feature. MorphOS and OS4 do support it if you have enabled "enhanced modes" on MorphOS or "compositing engine" on OS4, and these features need a 3D graphics card too.

I'm not sure if AROS has this kind of 3D accelerated layers.library implementation. If it does, it probably needs real 3D hardware and doesn't work on emulated environment... at least if the emulator doesn't state it emulates 3D cards...

I'm using this feature with my RNOWidgets program, and I created a software fallback mode for non-3D environments. It just grabs the background for the program from the desktop... and you must re-grab it every time user moves the window etc. It will be a bit flickery and can't update the background realtime like the enhanced/compositing mode would do.

I don't know if AROS running on a real PC this visual bug exist, because the people don't speak about these problems, only I know this because I'm using the AROS lite 2.5 from Carlo and I have seen this problem, also you program and mine to open PDF files can't open this format.

Just checked this on my Samsung n130 (native graphics driver), ArosOne 2.5 installed. Using @BGPIC does not load the alpha channel, but this does

LoadBGPic(1,"appleimg.png",{LoadAlpha=TRUE})

So looks like an issue with @BGPIC.

Cheers,

When you say open PDF format do you mean using Hollywood and the PDF plugin? Unfortunately not supported on AROS due to a limitation in it's C compiler, which even more unfortunately means Pangomonium and hTEX aren't available either

Thank you very much for your reporting and test on real hardware, now we know that problem is in Hollywood, I reworked all my program that I use the background pictures with alpha transparency for the intro, I tryed to make the programs like Windows starter programs.

Yes, I wait for this issue will fixed to AROS can to have other PDF readers for its system, using the plugin polybios that is available but that it doesn't work correctly.

I'd definitely second that! I'd love to be able to use hTEX too - as a science teacher that would be massively helpful. Right now I'm creating equations in Hollywood's text output using unicode characters for greek letters etc. but that's very clunky.

Cheers,
Nigel.

Humm, it will be interesting, if you need help with your project to make some program with equations with Hollywood, because I want know the posibilities of hTEX with Hollywood and Amiga systems.

Using LoadBGPic() instead of @BGPIC shouldn't make a difference. AFAIR in contrast to OS4 and MorphOS AROS doesn't support windows with alpha transparency, does it? So LoadBGPic() and @BGPIC will load the alpha channel but it won't be drawn correctly because AROS doesn't support it.
