Commander X16

Hi good afternoon.
a challenge for basic.

I have 255 r-g-b colors in a text file
The file is 255x3 colors, i.e. 765.
the values are simply one after the other:
0 0 0 240 240 240 0 0 128.....

how can you read the text file into basic and then convert it to pal and save it as x16.pal ?

how can you convert it so that you can see the 255 colors as
pal can read into the x16

Thanks.
greeting

First your going to have to put comma's between them all. Then you have to Divide each value by 16 and round them off to ints (So all must be between 0 - 15) our palette is 12 bit.

This code isn't doing exactly the same thing but it may give you ideas, It's doing something similiar.

If you haven't figured it out by this Thursday I'll write it for you and give you a Binary Pal file to load.

I have my R-G-B palette from the forum here, which I have put here. Now I don't know which one is the right one?

what kind of palette is that in the picture?
Is there an R-G-B sample program for this please?

I haven't found a program for the x16 yet that converts r-g-b into pal for loading into the x16.

I can write the program myself if you can give me the exact formula for it. there must be 255 colors for the file.

I also play with purebasic, so I can process it there.

Thanks.

This file has an error when starting.
I loaded it with basload.

Thanks.

PALENTRY = $FA00 + (COLOR-INDX*2) CX16-R = INT((RGB-R / 16) + .5) CX16-G = INT((RGB-G / 16) + .5) CX16-B = INT((RGB-B / 16) + .5) GB = (CX16-G*16) + B VPOKE 1, PALENTRY ,GB VPOKE 1, PALENTRY+1, CX16-R

There's both BASLOAD source and a Tokenized file there. Tokenized file you load with load. Also I think I did this one with the RAM Basload. There are subtle differences between the RAM version and the ROM version. I'll check my code there later.

The rom version is now in x16.

I think it's better if you use the built-in x16 because it is always adapted to the respective basload.

thanks

Hello, thanks for the help.
where did this RGB come from please?

my RGB :
255 x r-g-b
----------------
0 0 0
240 240 240
0 0 128
224 240 160
192 64 192
80 192 0
0 0 0
240 240 240
0 0 128
224 240 160
192 64 192
80 192 0

--------------------------------------------
my data :
CX16-R = INT((RGB-R / 16) + .5)
CX16-G = INT((RGB-G / 16) + .5)
CX16-B = INT((RGB-B / 16) + .5)


GB = (CX16-G*16) + B
CX16-R

could I then write in like this? :

$FA00 = GB
SFA00+1=CX16-R
SFA00+2= GB
$FA00+3=CX16
.....
...

When I wrote that ROM BASLOAD was not yet available.

As to your other question. I wrote that code fresh as an example for you.
