1. converting bitmaps to use standard palette and still look good
Hello,
I just wrote this function that is supposed to convert a bitmap
so that it can work with the standard euphoria palette but I'm
having problems. Apparently the pic I tried to convert has a
palette that has NOTHING in comon with the standard palette.
Does anyone know how to get this function to work or has anyone
already written something that does this or know of one?
Lewis Townsend
global function new_pal (sequence pal_n_pic)
-- this function makes a bitmap work with the standard palette
-- call this function BEFORE you call all_palette
object pal, pic, realpal
realpal = get_all_palette ()
pal = pal_n_pic [1]/4
pic = pal_n_pic [2]
position (1,1)
puts (1, "Converting bitmap to normal palette:\n[" &
repeat (' ', length(pic [1])/5) & "]")
position (2,2)
for x = 1 to length (pic) do
if integer (x/5) then puts (1, "#") end if
for y = 1 to length (pic [x]) do
--if find(pal [pic [x] [y] +1], realpal) then
-- UNREMARK THIS 'IF' STATEMENT AND 'END IF' TO
-- SKIP ANY PIXELS IT CAN'T MATCH
pic [x] [y] = find (pal [pic [x] [y] +1], realpal)-- -1
-- UNREMARK THE '-1' AT THE END FOR REAL ATTEMPT ======^^^
--end if
end for
end for
puts (1, "\n Complete, thank you for waiting")
return {realpal,pic}
end function

why don't you just use all_palette before you display the bitmap?

Hello,
Thanks David, for the palette function
I'll try it out right away.
Sincerely,
Lewis Townsend
PS. Matt was wondering why I don't just use all_palette ().
well, 2 reasons
1. I want to be able to use bitmaps with different palettes
in the same program without messing up the colors every time
2. I want to be able to use 256 color bitmaps in mode 18
