World: r3wp

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...?

graham, did you figure out how to use the parallel port and was that 
for printing?

Graham: yes, and data is parsed from the Adobe Font Metrics file 
and included in pdf-maker.r for the 14 standard postscript fonts.

Henrik, my latest demo has a button that prints to the parallel port. 
 As for choosing trays and paper size, I think you can set that in 
the postscript comments.

Gabriele, do you have a reference on how to use this font metric 
data ?

is there a method to center text?

I used a ruler :)

darn it

Ok, let's be serious

hmm... at least measure the size of the text

You can determine the size of the text based on the current point 
size

and you know the page size

so, you can center it in draw.

hmm... that would give me the height of the text, but not the width

isn't there a textinfo thing that tells you the width of text?

there is also a stringwidth command in postscript.

so, my approach would be to create a center dialect word, and have 
a postscript implementation and a draw implementation

textinfo doesn't seem to work inside draw

presumably you can use it in vid and use those values.

fair enough?

quite a detour...

but OK, I only need to calculate it for two lines of text right now

>> layout [ a: text "this is a line" font [ size: 20 ]]
>> line-list: make system/view/line-info []
>> textinfo a line-list 0
>> probe line-list
make object! [
    start: "this is a line"
    num-chars: 14
    offset: 2x2
    size: 104x23
]
>> layout [ a: text "this is a line" font [ size: 12 ]]
>> textinfo a line-list 0
>> probe line-list
make object! [
    start: "this is a line"
    num-chars: 14
    offset: 2x2
    size: 68x15
]

could be possible to simplify that...

isn't there a SIZE-TEXT function?

dunno

still needs a face

>> size-text make face [text: "hello"]
== 29x15

easier :)

throw in a font definition

example?

well, just the one used in DRAW for the text that needs to be printed

center: func [text width font] [
  width / 2 - second size-text make face compose [
    text: (text)
    font: (font)
  ]
]

that's what it takes

but it only works sometimes.. I don't know why

copy

found the bug
