A4                              595 x 842
   Letter                          612 x 792

so to change postscript to draw, for A4, it's 842 - y

If you have a 15" monitor showing say 1280x1024 and you have a 21" 
monitor with same resolution, you don't have 72 dots per inch on 
both.

how to convert a gray ( range 0 - 1 ) to a tuple! ?

Graham, Postscript is resolution independant. Certainly capable of 
more than 72dpi

Jaime, Postscript uses points for it's units and these are 72 per 
inch.

nothing to stop you using parts of a point.

first pass at taking the same postscript dialect and rendering it 
to draw.

I don't know if it's a bug, but Text in Draw does not obey the rotate 
commands, or the scaling commands.

the shaded box is in the wrong place .. not sure why, and I had to 
shift the bottom text up so I could see it.

So, my aim is to preview a page on screen in this dialect and using 
a different parser on the same dialect, create postscript which I 
can send to the printer.

Graham, what I meant is that even to the unit is a *point* the fact 
is that you can more than 72 pixels in a inch. For example laserprinters 
have 300 to 1200. And there is some displays that 96dpi, and I have 
seem e-ink that gives you 150dpi(s).

So the unit of measure doesn't have anything to do with the actual 
size of pixel or (dot).

(Excuse  my overscrupulous comments, now time for sleep.

do http://www.compkarori.com/reb/psd2draw.rversion 0.0.8

Allows a preview in 50%, 75% and 100% mode.

the print button, unimplemented, would send the post script file 
to your printer.

wow

that's really all I can say at this point

graham, out of curiosity, can you scale as you want? could you implement 
a slider? I'd like to see how fast it is.

Yes, could implement a slider .. if I can remember how to do sliders!

SLIDER in the layout and then use /data to extract the position which 
is between 0 and 1

:)

There's a free postscript viewer and allows you to print in windows 
here: http://www.rops.org/

It's http://www.rops.org/download/freescript53.exeand does only 
Level 1.

a measly 324Kb.

Uses windows installed fonts instead of postscript fonts to preview 
and print.

http://www.compkarori.com/reb/psd2draw.r

has a slider now for Henrik :)

it gets all screwed up when really small.

the fonts scale a little funny

Just uploaded a newer version that places the slider vertically.

I thought there was subpixel accuracy

it scales transforms as well, it seems

Perhaps I've done something wrong.

that gray box is not right.

as you scale it, you can see it moving closer to the other box.

It is supposed to be superimposed on the other box from the start.

no it moves and rotates. maybe SCALE is working too well?

As in, scales all transform parameters

Text does undergo scaling or rotations.

*doesn't

what if you convert the text to vectors?

could do ... use vectorial text.

I didn't try.

For those without postscript printers, using the free version of 
rops.exe might be a solution for them.

there is a free version?

I'm hoping someone who knows more about draw can fix this for me 
:)

free version of rops is level 1 ps.
