I put it into Rambo and into the library at rebol.org, as Carl promised 
it already once to include it in one of the former realeses.

scaling info.gif (which has an alpha channel) gives funky red and 
yellow stripes when specifying 2 or 4 points (but not 1 point).

This bug seems to have been introduced in View 1.3.2 and is still 
present in View 2.7.4
	  

 window: layout [b: box sky effect [draw [image info.gif 0x0 49x48]] 
 mag: box 600x600] 
	mag/image: to-image b 
	view window
It doesn't appear to be in the bug database.
I've been investigating the bug above with this script:

anton, testing both on XP and OSX. the bug does not appear on OSX, 
though colors are odd there due to a known bug.
another known bug, that is
it could be that the odd colors are simply hiding your bug, though.

It looks like it also has the alpha channel problem.
Try the above image-fit.r program, set it to 2-points and then play 
with the SIZE pair-edit.

that's a very tall window. it doesn't fit on my screen :-)

On XP you see red and yellow stripes in the alpha channel.
Ok, I was thinking of changing that anyway. Hang five.
Ok, reorganised. Try image-fit.r again.

it's difficult to tell. the colors are shifting very quickly, where 
there should only be subtle changes. there are colors that look like 
they shouldn't be there, but I can't be sure.

Do you mean it's harder to see on OSX because of the other colour 
problem ?
Henrik

yes
colors are bouncing all over the place when I resize it

Ok.
I'll post this later if no one else has any comments.
(The script I was working on which led to this bug was this one:

BTW I have fixed the OSX color bug so it could be added in next release.
Anton: the new image color problem you have found is 'by design' 
at the moment ;) The bilinear filter needs image data with premultiplied 
alpha when you want to use image with alpha/transparency. Another 
possibility is to use IMAGE-FILTER NEAREST which doesn't need premultiplied 
alpha in this case. I'll try to think how to solve this 'inconsistency' 
so it doesn't harm performance too much.
Anton

Hmm.. that's a bit annoying. Is there really no way the bilinear 
filter can work also on the alpha channel ? That would be a feature 
request to submit to AGG then wouldn't it ?
Good work on the OSX color bug. So now we'll both be able to see 
my bug. :)
Cyphre, so I'll submit a ticket to RAMBO.

Anton, according to the author of AGG the filter calculations would 
be much more complex and thus expensive if done in plain color space. 
Anyway, please submit a ticket to RAMBO I'll try to make the best 
to solve this issue.

Ok, very good.
Ok, submitted bug report to RAMBO.

get-modes s: open tcp://:87 'port-modes crashes new builds.
get-modes c: open tcp://localhost:87 crashes too.  
Probably similar to #3983, as copy get-modes .... works.

The crash does not happen, if the license.key is not available.
I submitted it to RAMBO.

do you have IE 7?
It's reproducible with more than one installation.

BASE-TEXT/init assumes that font/colors is a series, which means 
that this makes an error:

>> view layout [text "Hello" font svv/vid-styles/FIELD/font]

** Script Error: change expected series argument of type: series 
port
** Where: forever
** Near: change font/colors font/color
if none?
It is the third line where the error occurs.
>> print mold svv/vid-styles/base-text/init
[

    if all [not flag-face? self as-is string? text] [trim/lines text]
    if none? text [text: copy ""]
    change font/colors font/color
...
( and various text styles inherit base-text's INIT )
so... what to do about it ?

Is it the fault of FIELD font not having a colors block, or is it 
the fault of the INIT not being able to handle the NONE case ?
