World: r3wp

A (worldwide) universal document format is really something where 
you would expect prime support for utf.

Gab, is there going to be any user documentation for pdf-maker 2?

I don't think I'll have the time to write it myself in the short 
term. I'd be very happy to help anyone willing to write it though.

just dictate it !

I'd be happy to help with that too.

Nick, another tutorial!

I had a quick look at the source code for the demo pdf .. and decided 
that it's too hard to grok.  We need some clues and from that someone 
can write something for users.

First question, is the translation function also relative to 0x0 
or to the latest 0x0 point?

always relative to absolute 0x0, or to the latest 0x0 set by the 
last translation?

So, if we ask you questions we can build a manual from that? :)

transformations of any kind are always relative to the current coordinate 
system which is determined by "previous" transformations.

so if you nest translations you get a translation with the sum of 
the two vectors.

(or you can think of all transformations as matrix multiplications, 
then everything becomes simple :)

ok, like postscript ...

so how to reset ??

gsave grestore ?

(re: demo pdf, it was mostly meant as a "test suite" so it uses most 
of the features)

i use nested blocks, so normally you don't need to reset

no reset?

can you make an example where you need "reset"?

well, I have 4 blocks of text I want to move around...

or a graphic ( how do you include jpgs? )

apply translation 10 10 [ ... translated stuff here ...]  ... no 
more translated outside block...

if I always use 0x0 .. then I can just translate to where I want

you can think of the ] as a "reset" if you wish

so outside the [ ] .. you're back at 0x0 ?

exactly. the transformations are only in effect inside the block.

they are "local"

ahh... well, I just assumed it was like PS and View

so how to include a JPG?

let me check the syntax for the image command...

image x y w h load %file.jpg

i don't yet have a way to include the JPG data directly, i use the 
loaded image. this means that the image gets in the pdf without compression.

and all measurements are in mm ?

yes, unless you set transformations to use different units.

can we use points instead then?

72 points to an inch

i think one point is 0.35 mm, so     apply scaling 0.35 0.35 [...points 
inside here...]      should work

ok, great

(if you need greater precision, you can probably find the exact conversion 
factor on google)

so 

for i 1 100 10 [
	apply transformation i i [
		image i i w h load %file.jpg		
	]
]

would work?

transformation
 = ?

translation?

translation :)

if so yes, but maybe you want 0 0 for the image origin?

oh yeah ...

the x and y for images are there so that you don't have to use a 
translation each time :)

the other way it moves faster off the page

I think Nick has enough to start the tutorial :)

The question for tomorrow is .. how to get a block of text fully 
justified with microkerning
