as you see, it determines the image size, then sets the text margins 
so that you can make it flow around the image. it's a "trick" but 
it works if the image is not fixed within the page but moves around 
with the text, and you know it won't be split across pages.

so if you were doing a watermark you don't alter the text margins

correct.

you can also just put the image below the text boxes in the page 
template in that case.

for a floating signature?

you can use a vbox [ ... ] and put any graphic command inside it.

a box is "inline", eg, it is treated like it was a character. a vbox 
is considered more like a paragraph.

Carl should use pdf-maker to generate PDFs of the online docs

Is qtask using pdf-maker?

no. initially, we wanted to use it for wikis (ie. see my qml to pdf 
code), but the fact that the pdf was not an exact replica of the 
html output was not considered acceptable.

I tried this 

			append new-page compose/deep [
				textbox 10 10 100 100 [
					image 0 0 40 40 (load %247logo.png)
				]
			]
and not seeing any image in the pdf ..

graphic commands such as image are separate from text commands. inside 
a text "context", you can use box or vbox to enter a graphic "context". 
(also, you don't need the compose, as the dialect will try to evaluate 
arguments anyway.)

So:

    textbox 10 10 100 100 [
        box [image 0 0 40 40 load %247logo.png]
    ]


The difference between BOX and VBOX is that the former is treated 
like a character, while the latter is treated like a paragraph. (So 
you can have the former in the middle of a text line.)

ok, I'll try it again .. just with the above I got an error about 
expecting an image so I added the compose

Unless there's a bug, that should work...

When I use this command, I don't get an image, and my 13 page pdf 
stops at the first page

there's no png there...

ah, sorry, box requires more args, checking...

box width height depth [...gfx commands...]

depth controls the offset relative to the text baseline, for eg. 
the letter 'q' has a positive depth because the stem goes below the 
text baseline.

ok, trying again

append new-page compose/deep [
				textbox 10 10 100 100 [
					box 60 60 10 [image 0 0 40 40 load %247logo.png]
				]
			]

Doesn't work either

similar 

justify with margins mrgns box iw lh 0 [
                image xbl ybl - ih + lh iw ih img
            ] space 2

uh... while testing this, i got this:

Segmentation fault

linux?

of course

ah, wait, that was probably my fault... (yes, linux, i guess it should 
not segfault though)

this works for me:


b: layout-pdf [[textbox [box 60 60 10 [image 0 0 40 40 load http://www.rebol.com/graphics/reb-logo.gif]]]]

the image comes at the bottom though, which does not look correct, 
so I'm probably forgetting something...

Interesting .. I get nothing

right... i don't do a coordinate transformation, that's the reason 
for xbl and ybl in the above snippet

you get xbl (X Bottom Left), ybl, xtr, ytr bound within the graphic 
block

is that pdf-maker1 or 2 ?

v2 was done between 8-Aug-2006 and 17-Nov-2006

Ok, got it

got the image.

b: layout-pdf [[textbox ["Image: " box 60 60 10 [image xbl ybl 40 
40 load http://www.rebol.com/graphics/reb-logo.gif] " inside text"]]]

That puts the image inside the text correctly. v2 should also give 
you an error when the dialect is wrong, while v1 did just fail silently.

so this syntax doesn't work with pdf maker 1 ?

so I got the silent fail

no. v1 does not flow text automatically across pages, does not allow 
putting graphics within text, does not have the TeX engine, and so 
on.

v1 also does not evaluate arguments to dialect commands so you have 
to use compose etc.

ah... I've been using V1

I have this ...

if not value? 'layout-pdf [ *do %pdf-maker.r ]

v1 is very stable, v2 has never been exstensively tested. so it's 
not a easy choice i guess :)

so Cheyenne already had v1 loaded and didn't load v2 for me !

I'd suggest that perhaps this is because you never managed to write 
the user documentation!

I should have a layout-pdf2 .... so I can use both
