Vectrex overlays in need of vectorization (yeah, irony)
#312847 - 08/14/13 06:13 AM


Nick3092 on the MESS forums scanned three vectrex overlays (so far) which need to be cleaned-up and (maybe) vectorized, and turned into proper artwork.
He has other overlays and is planning to scan them as well.
(Would scanning these on a black or white or grey background be better, since they are partly transparent?)

The existing Vectrex overlay scans most emulators use are at something abysmal like 640x480 resolution, and need very badly to be replaced.

The scans can be found at https://www.dropbox.com/sh/319xd5496m1c4m3/8s86Jx3OiM

These are much better.

White's probably best, so that the scan captures the color correctly.

Very cool =D




RELAX and just have fun. Remember, it's all about the games.

Posted this on the MESS forum thread:

I have overlays for Berzerk, Solar Quest, Mine Storm, Armor Attack, and Scramble and would be fine with scanning them. What would be the preferred way? (Normal scan, scan with transparency adapter, scan both sides to get opaque mask, etc). And what dpi and format, I suppose.
-
Did a test scan last night and the transparency mode one is inexplicably much higher quality, both were done at 600dpi but the transparent one had many, many times more HxV pixels in the actual resolution, so there is obviously some other setting applying to the scan when using the transparency mode. It is noticeably much better, the tiny text is clearly readable and the colors seem more true, but the file is ~1gb compared to the standard scan which is well less than 100mb (want to say in the 20s). If the end result is vectorization then bigger and better is probably best, but I know that files that large will be hard to exchange. Downside is that the semi-opaque areas appear dimmed out, but that's obviously because of the method used to scan.

Either way, let me know if you guys want them and how and where.

I'm not sure what actual resolution the transparency adapter scan is yielding, I'm a bit curious (is it scanning with an alpha map as well?)
Not sure if the transparency thing is completely necessary, but if certain ink colors are more transparent than others it does make some sense. (Though I'm not sure mame's artwork system can handle that right now, to be honest! I.E. one additive layer and one screen/mask layer?)

1200dpi 24 bit color to png or lossless tif is how I'd do the scans.

I'm honestly not sure what's making the difference, the only thing I chose differently was using the transparency option, though, there may be something in the way it's scanning it...by default it tries to slice up the image as if it were slides and I have to override it to scan the whole area, so maybe it is doing some kind of ultra-hires-mode. When both are scanned as 600dpi TIFF, the normal one comes in at 58.6MB and the transparency one is 1.88GB, with resolutions of 3900x5010 vs 15729x19953 accordingly. Everything else seems to look the same, though obviously it is getting all the "extra" pixels from somewhere. If you have somewhere I could upload it to, you're welcome to take a look at them.

Ok, hmm. The documentation seems to be implying that it's scanning at 48-bit, though it's not really clear if it's keeping all of the data or post-processing it down to the "best" 24 bits. Photoshop claims that it's 16bits/channel now that I look closer so I'm guessing it's keeping the info.

Man, I just love HP's awesome, flexible software with easy to configure options and totally intuitive documentation. sigh. Have a new scanner waiting, just haven't bothered to hook it up yet and it doesn't do transparent media so I figured I'd try this one in case that's what you guys wanted.
