PAL emulation library or command line tool
I'm working on a tool where I am generating C64 images in PNG format (320x200, 16 colors) for use on the web. To make the images look better, I'd like to apply a PAL emulation filter on them, maybe also scale them to double size in the process.
Does a library or command line tool (preferable written in C, but at least portable) exist for this kind of thing, or do I have to roll my own? I guess I could take a look at the VICE code, but it would save me some time if there was something ready to use already. |

Groepaz has created something of this nature iirc. But not released |

@Perplex, not sure if you've seen this, but I guess It contains necessary info if you decide to roll your own stuff:

Seems like Groepaz has some code that might be doing what you need, as Algorithm said, though. |

i do have some reference code indeed - however it is slow and ugly and not really suited neither for release nor use in a real program. i hacked up some commandline tool for veto some time ago, no idea if he even ever used that =P... whatever, leave me a mail and we can work something out :) i wouldnt mind releasing the whole thing (with source) at all, just not in this terrible state =) |

view64 seems to be exactly what I need, provided I convert my source images to koala format first, and I already have code for that in my toolbox. Thanks!
Groepaz: It would be great to get preview images exactly like they would look in the emulator. I wouldn't mind helping out when I get some spare time. |

Groepaz. If it does the job that's all that matters regardless of how messy the code may be |
