Graham, your comment about diagram inspired me to do some drawing 
.. http://www.itmmetelko.com/blog/img/actor-net-scheme_t.gifI added 
it to blogpos

Jocko, in R2 if you use effect dialect to resize images, yes it uses 
nearest interpolation.
But draw uses blinear by default.
see:

img: logo.gif
siz: img/size * 4
view layout [
	below
	image img
	image img siz effect [aspect]
	box siz effect [draw [image img 0x0 siz]]
]


In R3 it's annouced that  image-filter supports NEAREST,BILINEAR,BICUBIC 
and GAUSSIAN interpolation

when using the REQUEST-FILE function anyone know how to prevent rebol 
from adding its own filters?


I'm specifying one, and it adds REBOL, *.*, and images... but its 
a stupid setup since I can't manage JPG or GIF images in REBOL.

>> view layout [
[     box white 327x327 draw [
[          pen logo.gif fill-pen off box 100x100 300x300
[         ]
[    ]
** Script Error: draw expected image argument of type: image pair
** Where: do-facets
** Near: draw [
    pen logo.gif fill-pen off box 100x100 300x300
]

you are missing the EFFECT facet in your code (the DRAW block is 
inside EFFECT block in R2) so the correct way is:

 view layout [
     box white 327x327 effect [draw [
          pen logo.gif fill-pen off box 100x100 300x300
         ]]
    ]

You can also use scale:

view layout [box effect [draw [scale 2.0 2.0 image logo.gif]]]

I'm using Christopher Ross-Gill's animation style. I wrote a little 
function to convert an animated gif to an image file that the style 
can use....

Kaj, I thought about doing something like that but how do you kill 
the process from rebol?

SELECT ... INTO Chart.gif
Nice addition to SQL :)

What I do at present is use a tab-panel and have the loading gif 
in one, and then replace that panel with the table once the data 
arrives

just a joke to try to generate a coverflow animation.

Two new alphas today - release early, release often :)

As of alpha 42 we now can load jpg, bmp, png and gif. The beginnings 
of the general codec architecture are there in the form of ENCODE, 
DECODE and ENCODING? functions. Oh, and LOAD has been rewritten again, 
with LOAD/next and multi-LOAD capabilities that go beyond R2.

Ammon - it seems we can't save in some formats, e.g. GIF ....

save : not gif. Only PNG, BMP like R2

To elaborate on what Gabrielle said, in most languages, there is 
a large and small version of letters for use usually in sentence 
case, and also for abbreviations, etc.  Over time these began to 
be written differently, so the large and small actually look different.


But in Japanese, small letters have a completely separate meaning, 
sometimes used to elongate a sound, or form a subtle guttural stop.

Here is a sample, it is VERY subtle.


http://christopherfield.com/translation/images/hashiriame/story_a.gif


In this image look for all the symbols that look like a backwards 
letter "C" (or letter "U" that fell to the left).

Sentence 1 - 3rd from the right.
Sentence 6 - 3rd from the left.

Notice they are very subtle different sizes.

That is an example.

Bottom line, as stated, don't mess with caps with Japanese.

(it was hard to find a GOOD example of this in the same image).

I tried to look-up some codecs, but there are none for text encodings 
as of yet:

SYSTEM/CODECS is an object of value:
   bmp             object!   [entry title name type suffixes]
   gif             object!   [entry title name type suffixes]
   png             object!   [entry title name type suffixes]
   jpeg            object!   [entry title name type suffixes]

Brian: I can't see how my code would be more optimized with map than 
hash (but I'm not a map! expert). For example, mime types lookups 
are made using a 1<=> N flat structure stored in a hash!.

make hash! [
	image/bmp	bmp
	image/gif	gif
	image/ief	ief
	image/jpeg	jpeg jpg jpe
	image/png       png
	image/tiff	tiff tif
	...
]

How can map! handle this easier than hash!? (looking up a mime-type 
based on a given extension)

the rss.gif image is missing from the img/ directory.

btw, you couldn't access the gif image, because my cheyenne server 
had decided to stop for some reason.

not cache, as it stopped after you fetched the gif.

I used it only several times - to initialise GUI automatically, and 
to create a primitive gif-anim player ...
