Hard to say it's a bug because there never was any documentation 
on the LED face

RE: printing vid faces by converting them to images for document 
printing...


I found that a multiplier of 3 is sufficient for good quality text...maybe 
5x for super quality

I'd say it's a bug Graham.

That means we can now write the documentation :)

what's the current bug tracker for R2 ?

Still RAMBO AFAIK. Unless they've moved things to CureCode.

hard to find stuff on rebol.net  now ....

ok, submitted

graham, might as well add it to my tracker too.

should ask Carl for a copy of the VID related bug reports so that 
you can fix them in vidext :)

that would be cool

How do you force a window to the front?  setting the activate flag 
and show doesn't seem to work

Anyway to set the Z order of windows once they are already up?

by forcing it to front, do you mean modal or just moving any window 
to front? (The kit has a simple function for the last bit)

Any window ...

What I want to do is keep a separate menu window open so that no 
matter what other windows are open, the menu window stays on top.

top-most example: http://pastebin.ca/1718241

I use the Windows API to do it Graham, but I don't have a cross-platform 
solution.

Inside a view window, you can remove the face from the pane and append 
it again, so it's a the top of the z-order. I can't remember trying 
that with screen-face though.

Thanks I'll give it a go.

I want to make a program that zooms in on a picture while I hold 
down the left mouse button and that zooms out when I hold down the 
right mouse button. Any ideas?

detect on mouse down and stop zooming on mouse up

Thanks Henrik

hmm... well, I guess you need to keep that going, while the button 
is held down, otherwise no events are fired.

Yeah, that's the problem.

Could I flick over to event detection every tenth of a second somehow?

yes, you can ... well, but I am not much experienced in that. You 
need to test event/type for 'time value. But how to get time events 
there? Maybe setting face/rate: desired-value-per-second could help?

I'll try that

Here's a prototype

window: layout [i: image rate 5 load %gtfo.jpg key escape [halt]]

zoom-in: does [i/size: i/size * 5 / 4]
zoom-out: does [i/size: i/size * 4 / 5]
down: false
alt-down: false

insert-event-func [
	probe event/type
	switch/all event/type [
		down [down: true]
		up [down: false]
		time [if down [zoom-in]]		
		alt-down [alt-down: true]
		alt-up [alt-down: false]
		time [if down [zoom-in] if alt-down [zoom-out]]
	]
	center-face i
	show window
	event
]

view/options window [resize]

REBOL []


window: layout [i: image rate 5 load http://rebol.com/graphics/kits.jpg
key escape [halt]]

zoom-in: does [i/size: i/size * 5 / 4]
zoom-out: does [i/size: i/size * 4 / 5]
down: false
alt-down: false

insert-event-func [
	probe event/type
	switch/all event/type [
		down [down: true]
		up [down: false]
		time [if down [zoom-in]]		
		alt-down [alt-down: true]
		alt-up [alt-down: false]
		time [if down [zoom-in] if alt-down [zoom-out]]
	]
	center-face i
	show window
	event
]

view/options window [resize]

Can comments be deleted?

I guess they can't. Anyway, thanks for your help!

comments here in Altme? No - they can't be deleted ...

This is the first step to creating a zooming user interface

What do you mostly use rebol for?

as for me - simple CGI stuff, some automatition tasks, few GUI utils 
....

In easy-vid, Carl creates layouts of a fixed size, and fits all his 
text accordingly.  Hypernotes creates layouts that are variable in 
height.  How is this done?

ie. control the width and let the height expand to as necessary.

set the width and then use size-text

If you use unview/only window, why should any other windows close 
down as well?

they shouldn't

I wonder if it's the Z order that is the problem

Maybe it's just a rebgui issue ...

It's also occuring if I use the close gadget at the top right ..

Yes, it seems to be a result of using rebgui's display/parent ...

Can't find the DRAW group anymore, so I'm posting here.

Does anyone know if IMAGE-FILTER BILINEAR is working in Draw? I see 
no differences with NEAREST mode (which looks horrible when scaling 
down a big image, even with preserved aspect ratio).

If BILINEAR filter is not working or not implemented (while being 
documented), that would be really a pity to have to code my own bilinear 
filter in REBOL which would be probably too slow to use, or install 
a 10MB library like ImageMagic...

bilinear only works with scaling up
