1. Light and slow crappy image scaling
I just wrote a routine to scale a titlebar (640*22) in the x dimension, ie.
to make it stretch to the left and right, but not in the height. The routine
can only scale one line at a time. I think it's slow, but I could be
wrong...
Here it is, you laugh and you die! (j/k)
object newline,ix
global function shrink_line(sequence line,integer l)
newline = repeat(0,l)
ix = 1
for i = 1 to length(line) by length(line)/l do
newline[ix] = line[i]
ix = ix + 1
end for
return newline
end function

PS. 'line' is a sequence of color index values into the palette (ie.
read_bitmap()[2][1]), and 'l' is the new length to give the line (ie. scale
it)
And, this comes from a Euphoria program, Interpretted that is.

Huh?
I just used the line routine above to create a "scale_bitmap" routine, then
I did a loop with Jiri's "scale_image" routine and my routine stretching the
same bitmap every iteration yet drawing them below eachother, and they both
draw it at the same pixel-precise speed!
Eighter it's a timing thing in ex.exe, or both routines are 100% equaly
fast!
Can I just attach the program to my mail?
Or won't that work?

You can, i.e. if it's not an EXE. But isn't it time to go to sleep now?

It was an exe, but forget about it, it's not *that* spectacular :p

Yeah I know...
It's 6 in the morning...
Never mind though, I'll sleep tomorrow! :p
