Ghostscript will not run that file here.

ah wait... let me check if your version of to-postscript properly 
supports images

it was wrong. please try again.

Doesn't work with my version of postscript. Why is the image change 
needed?

because otherwise I can't put images directly into the dialect and 
I will have to store them in a tempory place first and reference 
them with a word => much more code.

the changes I listed above adds image! support directly..

Ah, got it. *thinking*

With the change, I can produce a PS file, but I still can't see the 
image. Will try some stuff...

There should not be any change in my version of the image decoder.

Does this work for you?


write %imagetest.ps postscript [DeviceRGB [translate 100x600 scale 
100x100 image help.gif]]

Yes, I had to add DeviceRGB to see the image.

yes, it works

DeviceRGB is already added here. Is scale necessary?

Think so. :)

Yes, so your image is there, it's just tiny.

well, it still won't run the PS file.

Use scale 72x72 for 72 dpi.

back in 30 mins.

Henrik, I think, you need another factor. The one you have now, is 
set to 1. It's ok for your text. You have to put scale 72x72 (or 
something) when showing images.

I tried setting your factor to 72, then I can see the image, but 
the text is HUGE! :-)

BTW, if you don't mind: I've added a probe on the dialect code output 
in to-postscript.r. Then you can see if I'm writing something incorrect 
out.

interesting that you can run the file. I can't.

and I've already added scaling

I had a problem some time ago showing PS files, I produced. I think, 
it was some cache.

The dialect code, you produce, looks ok. I'm really not a shark with 
PS, so it doesn't mean, it's 100%, even if it looks ok to me. :)

Best way is to test, test, test, I'm afraid.

I can't get image! datatype to work in the postscript dialect (your 
suggestion). If I have it as a word, that is being "get", it works.

It's because, an image! datatype is the sequence
make image! [ ....

and that is being parsed.

I don't get The 'img variable is set to an image! type, just like 
it is when using load-image from a file or url (which I couldn't 
get to work either).

Sorry, should be:

I'm very confused right now. Images now work, but are placed in the 
wrong corner, despite being given the same coordinates as text and 
boxes.

solved the positioning problem

Henrik, did you create a dialect that takes a VID layout and produces 
a printout in PS?

Yes... I know it's 1am for you!

yes, I did

How well does it work?

actually not a dialect, it just converts a View object tree to postscript. 
it's used in the same way as to-image is on a layout.

Have you published it?

http://rebol.hmkdesign.dk/files/vid-postscript2.png

http://rebol.hmkdesign.dk/files/to-postscript.r

close ....

if you're doing B/W stuff and not worrying too much about text wrapping, 
then it should work.

since it works on a view object ... it should work on Rebgui as well

no bitmap support and no wrapped text support.

why not?

(which is why it says wednesday twice in one of the fields in the 
postscript output.

the ps dialect supports rebol image format

because that is handled at the View level. text wrapping information 
is not available in the layout tree.

Hope Vid+ doesn't have that limitation
