World: r3wp

got a bit of a makeshift preview now. maybe I'll use it for the next 
version for the other races I'm doing this for

So, you got mine working??

nope, I made a little layout that works like a preview

hand-made but it's enough

for now... later on I will be needing to create a real preview, so 
I'll be looking into it

to get the ps dialect matching the draw dialect, I need to make the 
text obey cr/lfs.

fortunately I don't think I need that

That's pretty good work Graham ! Well done guys.

OT: How to Spot Arial -- http://www.ms-studio.com/articlesarialsid.html

This is one of the main things that makes Arial look like Helvetica 
at first glance, even though the details are different.

At work today, and got a chance to try out the postscript printers. 
 It's amazing .. I can print from my draw preview to either the network 
colour postscript printer, or to the old HP Laserjet 4MP on the lpt1:

and with ridiculously little code

I'm wondering now whether the tendency for new printers to have built 
in postscript is going up or down...

I remember that NeXT printers were so cheap because all the postscript 
processing was done by the NeXt OS, and so the printer was just a 
bare engine.

A bit like Windows printers I guess.

If you don't have a postscript printer .. I recall in the old days 
you created a large bitmap in memory, and then printed it all out 
dot by dot.

I remember driving my dot matrix printer like that.

Now to do desktop publishing, need a hyphenation dictionary, and 
a way to do kerning.

Graham, in your demo above

How come the text disappears at different sizes ?

If you're talking about the rotated and transformed text, I think 
it's because there's a glitch in the way scaling etc is computed. 
 Probably my fault, and since I don't need scaling or rotations, 
I haven't looked at it very hard.

you can see the same problem with the shaded box which rotates and 
moves in closer to the middle as the size is reduced.

No, I mean all the different text strings disappear and reappear 
at different times as you drag the slider. Something to do with font 
size ?

Maybe scale-draw creates a font object with a size which is not supported 
?

For example, from code that scale-draw produces:

font1: make object! [
		name: "Nimbus Roman No9 L"
		style: none
		size: 33
		color: 255.0.0
		offset: 2x2
		space: 0x0
		align: 'center
		valign: 'center
		shadow: none
	]

font2: make object! [
		name: "Nimbus Roman No9 L"
		style: none
		size: 13
		color: 0.0.0
		offset: 2x2
		space: 0x0
		align: 'center
		valign: 'center
		shadow: none
	]

view layout [box 500x700 white effect [draw [
	box 0x0 493x698 
	fill-pen none 
	box 0x0 493x698 
	line-width 0 

 font font1 pen 255.0.0 text vectorial "REBOL PostScript Dialect" 
 59x68 
	pen 0.0.0 line 59x104 431x104 

 font font2 pen 0.0.0 text vectorial {With this dialect it's possible 
 to easily produce PostScript output.} 79x121
]]]

The second text does not appear for me on View1.3.2.3.1

but it does when font/size is at 15 instead of 13.....

Maybe my fonts are not so complete.

graham, i don't think you want to look at the code (still too ugly), 
but the pdf maker does kerning.

Anton, did you download that font pack I pointed to ?

When I look at the scaling, the only text that does funny things 
is the one that says "transformations"

I see both texts on my system.

as they are true type fonts, they should appear at all sizes.

Gabriele, do you use the kerning for all text placement in pdf-maker?

and where do you get the hint data from?  Is it read from the font 
somehow?

Graham, oh no I didn't, sorry I missed that.

Good idea to put a link to the font pack into the ps2draw.r header.

I've uploaded a new version with that information in the header now.

this version allows you to print to a network printer, to lpt1, or 
to a disk file, and then it calls the RoPS viewer.

A line with embedded CR is now rendered correctly in the postscript 
output.

I have a button "Edit" which imperfectly shows you the dialect source 
( strings lose their quote marks).  Not formatted though.  And save 
which is supposed to re-render any changes doesn't work .. because 
the data needs to be converted from text to a block, and without 
the quote marks for the text, it dies.  Too late for me to find a 
fix.

molded ?

Yeah, "Edit data" just forms the data, mold it instead.

Starting to look very good. :)

update a new version that shows the data formatted.

you can edit and save, and it redraws it.

But there is a context problem with the colours .. so I had to replace 
(red) and (black) with their tuples.

I guess I need to bind somewhere...

mold ?  Oh ... didn't think of that.

with postscript you probably can't control what tray you need to 
print from...?
