There's no rotate_bitmap() function, it seems. How do I ROTATE a graphic?!
Thanks!!

2. Re: Another NEIL Query
I apologize if this is a duplicate, but my Win2K PC crashed as I was
sending this the first time, and I don't see it on the listserv archive
yet...
I'm still desperately needing help with the following:
Using NEIL.E,
1. How do I load a bitmap then extract individual bitmaps from it? (For
instance, I have 15 64x64 tiles in the one bitmap file, and I want to
extract all of them to a tiles[] sequence.)
2. There's no rotate_bitmap() function, it seems. How do I ROTATE a
graphic?! Even if I could just get the 2-d sequence using the handle, then
I could rotate that and replace it...
3. When I try to display an rle_sprite, my machine crashes with a CAUSEWAY
error! Yipes! Any known issues? I'm using a Diamond Viper 770.
I've searched the neil.e docs but remain clueless on these issues.
Please help if you can!
Thanks!

look up information on sub-screens

couldn't tell you, sorry
you could always hack it out of another library that
has it, I'm sure there's one.

make sure you do it correctly. it should look
something like this:
do_command(rle_blit,rle_handle,{vs,x,y})
you could also use new_command()
Hope this helps,

I wouldn't have thought sub-screens was relevant, but I guess that makes
sense, if by "sub-screen" you can mean a portion of a virtual screen/bitmap
stored in memory. Thanks for the clue.

Yeah, I figure bitmap.e has a bm_rotate() function, but the problem is you
have to feed it a 2-d sequence, and I don't know how to retrieve the 2-d
graphic sequence stored by neil.

The "rle_handle" is an atom, as far as I can tell... right?
I guess since his "blur.ex" runs on my home PC fine, then I should be able
to use rle_sprites... I'll investigate further.
Thanks!!

NEIL has an actual object called a sub-screen. look
it up in the docs.

i think that you have 2 options:
1) figure out how the info is stored in the screen
structure and do it with ASM
OR
2) this is rather slow...
use get_pixel() (NEIL's) and read from the screen it
is stored in and then do what you want with the new
image

yes...it is a memory address

that's probably a good sign
