(and scale all the graphics involved in your face)

use 'draw' to lay it out wll produce better image?

the fonts will be anti-aliased (which is what I meant to say above)... 
but in any case, the resolution you use on your printer is always 
much higher than you screen resolution.

How far did Henrik get with his vid to pdf dialect?

My layout is all text except for one small b/w image...
Maxim, so to display a proper page I would need to increase the sacel 
of my vid image quite a bit...larger than screen?
sacel = scale

so if you are creating images for printout, you have to think larger 
faces with larger font sizes... screen dpi is typically between 72-100 
dpi, printers now usually printout at around 600 dpi.... so if you 
want to have clean images, they should be around 5 to 10 times larger.
yep.
when I was doing an art project, I had to create a printout for a 
36 inch wide image... the file was an 508 mb, 300 dpi image.
normal printing, uses vectorial information, so the convertion from 
shapes to points (rasterization) is done directly at print time.
using anti-aliased images you can lower the resolution  without it 
looking too bad... cause the edge will gray out instead of being 
jagged blocks.  but they will look fuzzy instead.
for printing from REBOL, the best thing is to use one of the variations 
of the PDF dialects out there and printing that out.  there are a 
few guys around here who have some experience doing this.

I was using a print method calling MS image viewer transparently 
to print without opening up but I as adivised to keep my image at 
612x792 to keep it on one page...how do increase 5x  now?

you need to set the dpi of the printout to a higher value.  I don't 
know about that solution, but either it supports the dpi value of 
the input image, when it has one, or you should be able to set it 
directly.

612 / 72 = 8.5  ;-)  so your values are standard video dpis
photoshop allows you to change the meta information about dpi without 
resizing the image... I don't know if there are little tools which 
you can run command-line that will do it too.

I played around with it...
AGG looks great on screen but prints fuzzy like you said...
Increasing resolution looks sharp on printout...

I do not know if I should spend time playing with scaling or just 
biting the bullet and converting output to HTML or pdf ...I had planned 
on it anyway but as usual what I thought would be a quick one or 
two day project turns into a week to make it "right"...

But always an opportunity to learn new stuff!
Thanks for the help Maxim.

the pdf conversion should actually be pretty easy.  look it up. pdf 
maker supports images, vector art... and its a dialect IIRC so it 
should be a big thing to go from your view layout to this other dialect.
with R3, someone is bound to make a client for the windows printing 
engine  :-)

amacleod, it's VID to PS and it works fairly OK. I've used it for 
printing some statistics tables.

Oops, View, not VID. It only depends on faces, not the VID dialect.
also it doesn't output postscript directly, but dialect words for 
Geomol's postscript.r dialect.
doesn't support bitmaps yet (have only used it for printing text), 
but you use it like to-image.

Is this a VID bug??

>> view layout [ led 20x20 ]
>> view layout [ led 20x20 [] ]
In the first case the led can not be switched using the mouse, but 
by adding the action block it can !
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.

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 :)

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

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

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)
Graham

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.

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.

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?
Henrik

detect on mouse down and stop zooming on mouse up
