Ugly black border, how to change?
How do I get rid of the ugly black border all around my Blitz program?
Can I change its color? Better yet, can I add some copper bars out there? |

Isn't the border just colour 0? So you can change it to any colour you like or make copper bar effects fairly easily?

How can I change the border color without just changing color 0? I am using color 0. Also as I mentioned would be especially nice to have a copperbar border. |

You would do it in the copper.. Wait for a position, change colour 0 to whatever, wait for a position and change it back to what it should be and so on.. you'd do this for every scanline. the change back would be the area of the screen you're using I guess |

Wouldn't that write over my bitmap?

- remap picture so it doesnt use color 0
- do copper effects on color 0 (which affects background/border) - done Of course it very much depends on how easy or hard step 1 is possible. Have you solved it in the meantime? |

Bippy above says basically what needs to be done, but I don't even have any idea how to "wait" for the beam to finish a line. I know how to do that on a C64 with assembler, but I have no idea how to do it on an Amiga with Blitz. Is it the Vwait command? Remapping the graphics to not use color 0 might be OK, but they use it for transparency on slices being cut, wouldn't that affect that? Last edited by Amiga1992; 17 March 2021 at 16:31. |

You don't just want a bit of overscan?

That's not at all what I want, I want to add a copperbar border, which also brings me to the matter that, yes, it must exceed the overscan area, so again, how would I do that? My bitmap only takes the "inside" part of the screen
Also overscanning the graphics would introduce more issues than solutions. |

But, I think you might have issues getting the colour change to happen at exactly the same point that the inner part of the screen starts. Some math will be required. |

I'm willing to just have rasterbars going through color zero even if it "invades" the inner graphics now.
But still have yet to see anyone sharing any rasterbar source. |
