Not currently from TIFF. IM 7 can deal with extra channels but only in its internal format. This was being worked on for TIFF quite a while ago, but got suspended due to other higher priorities.

I think your ImageMagick version 6.9.7.4 may be buggy or -grayscale was not fully developed by your version. Where are your images? So I made an example. The following works fine for me on IM 6.9.10.63 Q16 Mac OSX. convert logo: -colorspace gray logo.tif identify logo.tif logo.tif TIFF 640x480 640x4...

Have you tried using Q32 or Q16 HDRI compiles of ImageMagick?

Always best to include input an output images. You can post to some free hosting service and put the URLs here.

As far as I know, ImageMagick cannot currently handle extra channels such as your alpha channel in PSD. It only processed background transparency. You could request an enhancement, but I suspect there would like be no guaranteed ETA, since the developers are very busy.

@Jimbo, What is your version of ImageMagick and on what platform. To save to higher bit-depth you will need HDRI to go outside the quantum range, I believe.

I have moved your post. You tacked that onto a completely different topic. Please do not do that. Create a new topic for a new question.

Please post your images to some free hosting service and put the URLs here.

As a guess, your PDF file does not contain the required font to properly render it.

Why is your image blurry?

This works fine for me.

You can use mogrify to process all images in a directory with one common image in a composite operation. See https://imagemagick.org/Usage/basics/#mogrify https://imagemagick.org/Usage/basics/#mogrify_compose First create a new directory to hold all your images. mogrify -path path/to/newdirectory -f...

Yes, that is what I suspected. But I needed confirmation. How did you determine that the photo was correctly oriented?

I cannot get -auto-orient to work. It seems to correct the EXIF orientation flag, but does not rotated the image to the new orientation. So it still displays incorrectly. Perhaps I am confused about what it should do or the file is corrupt in some way. I am reporting this here in response to a quest...

Your version may be buggy or too early for connected components. I get the same error when using IM 6.9.7.4. So try to upgrade and try it again. It works fine for me on IM 6.9.10.63 Q16 Mac OSX.
