Dan and others doing PostScript with the NeXT: has anyone else
noticed the following?
 
Build a simple IB app with a bunch of browser objects, buttons, whatever in
it.
Make the app so that it has a print menu. link the print menu to the created
window (with the browser, buttons, whatever) so that you can print and print
to disk.
 
run the app and print the window to disk. Take a look at the code in YAP.
 
Why is it that IB generates binaries for some parts of the window and PS for
others? Why isn't it "pure."
 

This question comes up because the publication of documentation with screen
dumps IN THEORY should be resolution independent. But, due to IB impurities,
it is not (along with every app for screen shooting is doing Tiffs).
 
What's the problem? Well, if you try to imageset this, it looks like crap. The
distortion patterns (moires) look crappy. I understand this happening when one
is working with tiff images or EPS images with binary info in them; I
understand it happening when people are doing alpha-channel graphics (if I
have this wrong it is because I am still learning the cube) that have opacity
setting that are not possible in PS.
 
But I sure the heck don't understand it when it is happening in areas of
windows, (where the sliders are) and other fundimental window elements. It
seems that it is just do to people designing part of IB with tiffs or bitmap
graphics, instead of using PS code.
 
What do you think?
 
Please correct me if I am mistaken. Again, I am new to the Cube, but feel this
really shoots down some claims about "ultimate pub platform" if the docs come
out screwy.
