1. Features and a Question
First, the question. Can I display high or true colour JPGs in Euphoria?
Has anybody written any routines for this? I don't know where to start
anyways 
.
This is what I want to do. I want to write a simple fake 3D (and I do mean
fake using true colour JPGs of my bedroom (if I can fit in it , and
then use the details from my bedroom JPGs to make up the fake 3D program,
then a real 3D program in Euphoria. Can anyone provide me with any routines
for me to do this? I don't use the infamous GIF format because:
A. You have to pay royalties with ANY program that uses GIFs
B. GIF only has 256 colours and no layering.
To do what I want to do, it just isn't fesable to use GIFs.
Now to the Features post by Jiri:
What I hate most about Euphoria is the variable declaring. BASIC, even C is
relatively easy to declare variables. I used to use BASIC, Pascal, or C to
do my programs for my maths class. I use Euphoria now, though. Rob showed
me how.

P.S. Uh... Jiri, he's gonna get your messages anyways! He's gone, but is
his
e-mail?

as far as I know, JPG's aren't implemented yet, in any
of the available libraries.
However! you can get true color if you are willing to use
Targa. If (for ex.) you use paintshoppro, simply make
your resulting images in the 24bit, uncompressed targa
format. you can use the batch processing feature of PSP
(which is why i suggested it--i assume you already have
these jpg's) to convert an entire directory of images in
a fell swoop.
then you will need the truecolr.e library from chris
street, available on the main euphoria page.
that library does have a bug or two... the bug
that will keep you from doing things however, is rather
nasty.
below you will find the fixed function in that library
that causes a heinous error... just cut/paste back
to the library and itll work properly. the library
is quite lacking in 'the basics', and i'm one bug
away from uploading a new truecolor library, with
many, many new features, and truecolor mouse support
as well (what's stopping me is the damned mouse cursor
keeps wrapping around the right edge of the screen...ARGH!)
last note: for some reason you need to 'flip' the
targa images along the horizontal axis (top->bottom)
before saving them...it'll display the image upside down
if you don't...doesn't seem to be a problem with the
library code tho...not sure.
here is the fixed function:
global procedure copy_image
(atom a1,atom a2,sequence w1,sequence w2)
atom b1,b2
integer nx,ny,wid1,wid2
wid1=get_width(a1) wid2=get_width(a2)
b1=a1+8+((w1[1][2]*wid1)+w1[1][1])*bpp
b2=a2+8+((w2[2]*wid2)+w2[1])*bpp
--this is the bad line
--it used to be:
--nx=w1[2][1]-w1[1][2]+1
nx=w1[2][1]-w1[1][1]+1
ny=w1[2][2]-w1[1][2]+1
if nx+w2[1]>=wid2 then
nx=wid2-w2[1]
end if
if ny+w2[2]>=get_height(a2) then
ny=get_height(a2)-w2[2]
end if
for e=1 to ny do
mem_copy(b2,b1,nx*bpp)
b1=b1+(wid1*bpp)
b2=b2+(wid2*bpp)
end for
end procedure
