identify does not recognize Color Spaces properly

Fred, I have not upgraded IM. I am running the stock installation from Ubuntu.

Code: Select all

$ convert --version

It bothers me that gs is not showing in the list. Though on windows it never shows. On my mac and I thought other unix systems it would show.

What do you get from

convert -list configure | grep "DELEGATES"

Does it show there?

[pauloney]

I get:

Code: Select all

$ convert -list configure | grep "DELEGATES"
DELEGATES      bzlib djvu mpeg fftw fontconfig freetype jbig jng jpeg lcms lqr lzma openexr pango png ps rsvg tiff wmf x xml zlib

Interesting, but I still do not see gs listed.

What do you get from

Code: Select all

convert logo: logo.pdf
convert logo.pdf logo.jpg

[pauloney]

I imagine you want the verbose on the second command, no?

Code: Select all

$ convert logo: logo.pdf
$ convert -verbose logo.pdf logo.jpg

OK. So although it does not show up in your list of delegates, it does work and still thinks the PDF is PNG.

Mine show PDF and not PNG for the input:

Code: Select all

convert -verbose logo.pdf logo.jpg
/var/tmp/magick-241vPkxt0vMHhVU1 PNG 640x480 640x480+0+0 8-bit sRGB 72.7KB 0.040u 0:00.039

In my opinion, something seems clearly wrong with your IM or ghostscript.

I recompiles IM 6899 and ran the same identify command and it does show PNG.

Code: Select all

im6899 convert -verbose logo.pdf logo.jpg

So it must be a factor of that version of IM, which may have a bug. The IM developers would have to say for sure.

Perhaps the older systems were reporting the raster type for imbedded raster images in the PDF shell?

[pauloney]

Any updates on the situation of this bug?
