Re: Software ORICAID by MICROGRAF Help Archive

Most (all?) of the modern USB tape drives, from the 15$ "Super USB Cassette Capture" to the "Aldi Boombox", to the "Toshiba Aurex ‘Hi-Res Cassette deck’" or expensive "TASCAM 202ᴍᴋVII" are using similar low-end mechanism made by Tanishin because they are the last company still producing tape mechan...

Re: Pictoric (was: New conversion algorithm)

While I was thinking around what I could do for the next Forever-Party, I've tested the conversion algorithm over several pictures of robots. Result is pretty good and I'd thought it would be great to share them with you.

Re: Pictoric (was: New conversion algorithm)

yeah, just put the file Pictoric.lua where you want, then right-click on the Fx button (it'll become white). Use the browser to pick the file where you placed it (GrafX2 will remember the location for next time). Press the "RUN" button, and voilà!

Re: Oriclopedia: A series of videos on all things Oric

But I guess what you did with your picture conversion program could indeed probably be done to convert pictures in some "pointiliste" style, would be interesting to try :) Actually, I wrote horizontally, but internally thought vertically(!). The idea being something like the -f2 (RVB) mode of PictC...

Re: Oriclopedia: A series of videos on all things Oric

We don't see the printing-head very well, but from this other video https://www.youtube.com/watch?v=irvMGZVNRx4 I can see this isn't a dot-printer at all, but rather a "vector" printer. How do you convert the screen bitmap into the proper vectorial form? Notice: it is bad they choose R/G/B pens beca...

Re: Pictoric (was: New conversion algorithm)

Maybe in v1.1 I'll add code to consider that low-intensity pixels are actually black, removing these scatered pixels here and there. But I need to test before, because this could also alter the quality of some other pictures. I have made a test, but it seem that too much "dark" things are being del...

Re: Pictoric (was: New conversion algorithm)

The comparison of Dali's painting you made, shows many differences http://puu.sh/EmWSH/206f2de6e9.png http://puu.sh/EnhCg/75f1117be8.png That's odd. Removing the pixels shouln't alter the remaining ones. But your 2 versions of Dali's paining isn't showing this. If I analyze the 1st picture above, I ...

Re: Pictoric (was: New conversion algorithm)

I have tested few pixel-art pictures from Prowler, and the result is pretty appealing :D

Pictoric (was Re: New conversion algorithm)

[EDIT] Oh! I have an idea. I need to experiment on the images of the SVN (once I can download them successfully ;) ) Okay.. I tested the idea and it worked well. By default the algorithm uses a heuristic to guess wether or not the first octet of each line should be kept blank or not. Oric's complia...

Re: New conversion algorithm

I have just checked >> this << and >> that << picture, and milou isn't white. It is #FDFAE9 and #EFEFEF respectively. This probably explains the small dark spots, but I need to check the original I have at home(still at work atm.. ush!! ;) ). [EDIT] in the picture at home milou isn't fully white too...

Re: New conversion algorithm

I can't get any of the binary file from the svn browser (it shows as ascii, see >> this <<). What's the trick? I can make that 6 pixel blank margin an option changeable with a flag. But how to detect that the flag is to be set to true or false ? I don't see any well defined decision procedure here: ...

Re: New conversion algorithm

This is because in the code I have put this protection local function getLinearPixel(x,y) if x<6 then return Color:new() end -- first 6 horiz pixels are reserved The algorithm doesn't do anything special to those 6 pixels, it is just that I thought that colored pictures always need to have these 6 b...

Re: New conversion algorithm

The algorithm should keep oric-compliant images[*] as is. One can check that the total error in the picture is 0 in that case (see highlighted value in screenshot below), meaning that no pixel where harmed during the process. ___ [*] 240x200 pixels, columns 1 to 6 left blank (the algorithm will igno...

Re: New conversion algorithm

Actually it isn't the whole picture which optimized, but a single line. This is already a big simplification of the problem since the state-space for a whole picture is (state-space-for-a-line)**200 which is something like 5E+9000 (15**8000) possibilities to test... This is far too big to have real ...
