inefficient to produce a single postscript file for each layout

yes, true

I can upload it it you want to play with it.

sure ..

My method is because I have a single document that goes over many 
pages

http://rebol.hmkdesign.dk/files/to-postscript.r

load Geomol's postscript.r first.

where is it?

this one ? http://hmkdesign.dk/rebol/postscript/postscript.r

yes, that will be fine

neat

I've now added multipage support (simpler than I thought)

even better

Anyway, excellent way to get a screen print of a View layout

it's almost stupidly simple. :-) it's one of those things I wish 
I came up with 2-3 years ago. could have saved a lot of work. the 
secret is just to slavishly follow the offsets and sizes already 
generated with VID or RebGUI.

no fancy postscript measuring tools are used.

I'm not sure it would work with microjustification of text

we don't have finer type setting features, but I can live with that, 
as long as I have a simple and quick way to build postscript pages.

can you get that type of resolution with View?

if you scale your view up and then appropriately scale the postscript 
down, yeah

scale it up so that it's too big for the screen?  :)

yes, you can create 10000x10000 layouts if you want to, they just 
won't fit on the paper without scaling them down. I did something 
similar once in a different system, but it proved to be unusably 
slow on smaller PCs and it eats memory.

yes

I may add scaling, if it makes sense

So, will this work images etc?

image support depends on if postscript.r will get support for image!. 
currently it seems only to support direct loading of jpg, gif and 
bmp images.

image! support is necessary if we want to output the face/image and 
face/effect parts of a face

scaling now added. use to-postscript/scale my-layout 0.1 to increase 
precision by 10 times. this means you must create your layout 10 
times bigger.

so what elements can you support now?

text and ?

text and boxes

ok

DRAW is probably too hard to get in. I don't personally need it.

perhaps we should move this to the postscript group

Can you put bitmaps in a postscript file ?

(moved to Postscript group)

I've come across what seems to be an oddity with View on the Mac.Iit 
seems that the Rebol/View console is using UTF-8 encoding but that 
View is using MacRoman.

the "console" on Mac and Linux is just a terminal (OS provided), 
and they are usually UTF-8. That has nothing to do with View.

How can I return something when using DISPLAY/DIALOG when the dialog 
is closed? Something like:

result: display/dialog [...]

Or is this only possible via a wrapper function?

Sounds like Rebgui

display returns the layout ...

Or  maybe

catch [display/dialog "test" [button "button" [hide-popup]] throw 
"result"]
which is equivalent to a wrapper function I guess

btiffin, why would you need the catch and throw there?

I solved it now by writing a function that collects and returns the 
result. And this function contains the DIALOG stuff.

Sorry, this was an attempt to get round the none returned when the 
sysclose is used ... did I go overboard?  could be

what i meant was, why not just do [ display ... "result"] ?

Yep.  Pull head out; breathe.  ;)

Does anyone know how to adjust the saturation of a single RGB value?

Chris Ross-Gill might know. He's done a number of color adjustment 
bits.

It's interesting that I can find tens of places with getting the 
saturation of an RGB value, but not the other way around. I must 
be asking the wrong question.
