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

simplest form (default values used for everything):

textbox [
    "This is an example"
]

that does both left and right justification?

yes, that is the default.

(you'll need a longer string to see it of course :)

do you have a hyphenation dictionary?

no, you have to handle that.

so does it just wrap on words?

yes.

you can define hyphenation points with --

eg.: "This is an ex" -- "am" -- "ple"

so if you have a dictionary, you can preprocess your text and just 
output that.

hyphens have a slight penalty so the engine will try to avoid them 
unless necessary. it also tries to avoid more than one in a row.

kerning?

it is automatic.

you can add manual kerning with the kern command

eg. "abc" kern 1 "def"

so if text flow is automatic ... how do you know if the text overlows 
the box provided?

or, how does one flow text from one page to the next ?

what you can do is create a stream of text, and then flow it across 
multiple text boxes, or multiple pages.

eg ?

for example, see the text that starts at page 4 in the test.pdf file?

that is defined in the test-pdfm.r file where it says:

text book [
    ....
]

then, the pages are defined as:

    any [
        textbox  10 29 90 248 from book
        textbox 110 29 90 248 from book
    ]

which means: "create ANY number of pages, as necessary, using the 
following as the template for each page"

so that means you must have headers and footers too?

the template can include anything you wish, images, other text, etc.

i don't remember if page numbers are implemented or not

so book is the template?
