Public bug reported:
When running:
$ pdfimages -list grayscale-document.pdf
the output is:
```
page num type width height color comp bpc enc interp object ID x-ppi
y-ppi size ratio
--------------------------------------------------------------------------------------------
1 0 image 2556 3288 rgb 3 8 jpeg no 7 0 301
300 200K 0.8%
2 1 image 2556 3288 rgb 3 8 jpeg no 12 0 301
300 275K 1.5%
3 2 image 2556 3288 rgb 3 8 jpeg no 17 0 301
300 395K 0.8%
4 3 image 2556 3288 rgb 3 8 jpeg no 22 0 301
300 583K 2.8%
5 4 image 2556 3288 rgb 3 8 jpeg no 27 0 301
300 317K 1.3%
...
```
"rgb" is incorrect, which is evident after running: 'pdfimages -all -f 1
-l 1 grayscale-document.pdf foo && identify -format "%[type]"
foo-000.jpg', which correctly outputs "Grayscale".
Strangely, when "pdfimages -list" is fed a bilevel document, it states
that every page has color "gray".
