532.0. "PAINT AND POSTSCRIPT INCOMPATABILITY" by DODO::MARTIN () Tue Apr 04 1989 16:22

I am having trouble with printing a figure from paint. When I pick the post-
script for file type I get the same jagged output as if I pick the ascii2
and get a sixel. Why is that? This also holds for the fonts. Yet the postscript
is large and does have the postscript language in it.

Any suggestions?

532.2DON'T QUITE UNDERSTANDDODO::MARTINThu Apr 06 1989 14:2112
Why is it that I can bring I need a LPS40? Why can't it work on my LNO3R?

I can print fine with DECwrite. Is this going to happen with anyone else who
dosn't have the LPS40. I can create graphics fine on SIGHT and print to a
Scriptprinter. Don't quite understand why one place and not another?

Your answer certainly fits what is happening.

Thanx,

Ken

    RE: .0
    
    Paint composed/edits pictures as bitmaps at screen resolution.  So,
    your picture is either 75dpi or 100dpi, depending on your monitor.  It
    doesn't matter where you print your picture -- its resolution will
    never be better than what your monitor was.  It's resolution could get
    worse if you printed it on an output device with a lower resolution.
    
    Please note that bitmap (and pixmap) editors always have this
    characteristic.  You are editing a set of pixels so, for example, a
    circle is simply represented as the pixels needed to be turned on to
    draw said circle.  This is as opposed to a true graphics editor.  A
    graphics editor will remember a circle as a circle, but draw it
    according to the current output device.  In this case, the
    PostScript(r) output will be much better than the screen output!
    
    RE: .1
    
    As far as I know, there is no such thing as "object-oriented" PS.  I
    believe this meant what I said above.  If you had a 300dpi screen and a
    300dpi printer, e.g., a LPS40 or a LN03R, then the output would be the
    same on each.
    
    RE: .2
    
    Never fear, the LPS40 and the LN03R are both 300dpi devices.  Both
    DECwrite and SIGHT are graphics editors as I described above.  Paint is
    a pixmap editor...

    PostScript(r) is a registered trademark and should be followed by the
    registered trademark symbol or "(r)".

    That's certainly true for bitmap/pixmap editor which belong to the old
    Mac Paint generation (DECpaint belongs to this category), but newer
    Macintosh paint packages let you paint at, say, 1,500 dpi (Laserbits or
    whatever). Won't look very sharp on your screen, but will look great
    once printed with the appropriate (expensive) hardware...

532.7Will this change?DODO::MARTINFri Apr 07 1989 20:2415
Are their any plans to make paint better in this respect? Doesn't this
defeat the purpose of DECwindows and applications that support each other?

Now I know why I created a diagram on paint that has nice fonts and looks
nice but comes out jagged in DECwrite? Does this sound true? If so then I
guess I'm stuck using the draw capability within DECwrite. I prefer the
flexibility of paint instead because of its pixel editing and zooming and 
some other things write doesn't have yet. 

Correct me if I'm wrong on this.

Thanx for replies.

Ken

    If you wan't to edit pixels, then the only solution would be to
    have a paint editor that allowed you to edit at the resolution of
    the output device (typically 300dpi).
    
    I doubt you would want to spend the time editing pixels if you really
    wanted good output on a laser printer.  So the solution is to use
    a program like DECwrite that allows objects to be created.  Try
    using the smooth function for polylines and I doubt you will ever
    want to edit pixels again.  If you are doing some type of artwork
    that really requires editing at the pixel level, then you are out
    of luck (as far as I know) at the moment.
    
    (you could always look for access to a Apple MACintosh, IBM PC, Atari
    ST or Commodore Amiga to do what you want :-)  To be fair, I think
    we are heading in the right direction, it will just take some time
    to get all the tools in place.
