convert anomalies.

[John Culleton]

In Inkscape created a .ps file with a yellow and a magenta rectangle.
Then I ran:
convert inksrc.ps -colorspace CMYK inkout.ps
The inkout file was huge. And the colors changed to green and blue.

Then I ran:
ps2pdf inksrc.pdf
and
convert inksrc.pdf -colorspace CMYK inkout.pdf

The output file was 117 times as big as inksrc.pdf, but the colors were
the same as the inksrc.pdf.

I think it obvious that a conversion to bitmap took place. Now, did a
conversion to CMYK colorspace actually take place?

ImageMagick basically is a bitmap graphics manipulation program. It can
import some vector formats, but you cannot create a genuine vector
graphics format as output. When you create a PDF, it's a PDF shell
wrapped around a bitmap.

As as test, I converted a PDF to CMYK PDF with IM on my computer and
then typed

identify -verbose test.pdf

into a DOS box. (Identify is another one of the IM command line tools)
and said that the colourspace is CMYK.
