Re: question about Face identifications?

ImageMagick does not have any specific face detection or recognition tools. You might try OpenCV, which does.

Re: convert & pango - "couldn't load font"

Pango does not specify fonts in the command line. You have to do that in the pango markup language. See http://www.imagemagick.org/Usage/text/#pango There are many place where the type.xml file may exist. You need to check each. See https://www.imagemagick.org/script/resources.php for the locations....

Re: convert & pango - "couldn't load font"

Are you sure you actually have that file in your fonts directory? Might it be corrupt? Does your command work if you use -font Arial-Black rather than the path to the font file? Do you have pango properly installed so that ImageMagick can find it as a delegate? Does your command work with any other ...

Re: [CLOSED] possible bug +distort polynomial

Anthony, perhaps I was wrong. I though you needed derivative in both directions to do the EWA ellipse computations. I seem to remember having to give you derivatives in both directions. Am I wrong? Or was that only with regard to +distort?

Re: convert & pango - "couldn't load font"

Windows use backslashes for directories. You have used forward slashes. That would be OK if you are using Windows 10 Unix environment. Otherwise change your font path to use backslashes \ not forward slashes /. For example have a font at c:\windows\fonts\arialnbi.ttf. But I do not see one that is c:...

Re: Using the newest image in a list command

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.

The following command (with +antialias removed) works fine for me on IM 7.0.8.2 Q16 Mac OSX. magick -size 4000x800 xc:none -fill "rgb(17,35,39)" -font /Library/fonts/KumarOne-Regular.ttf -pointsize 300 -strokewidth 1 -stroke "rgb(196,167,194)" -gravity NorthWest -annotate +0+0 "This is first line." ...

Re: Convert svg to png with transparency

Perhaps you are using the internal ImageMagick MSVG/XML renderer, which on older versions of ImageMagick is not as good as Inkscape or RSVG. If so and you do not want Inkscape, then install the most current RSVG delegate into ImageMagick on both systems. You can check if you have it as a delegate us...

Re: Boolean detection of a face, any face

I do not think there is a nice easy face detection in ImageMagick. I would suggest you try something like OpenCV where they have trained data to do face detection.

Re: Filter to improve some tif images

It would be better if you provide an example. This forum does not allow uploads. So you need to post the image to some free image hosting service and then put the URL here.

Did you check your version of Ghostscript? That could just be the issue.

Re: possible bug +distort polynomial

After looking into it further, there are no easy inverses for arbitrary polynomial other than first order and some very simple higher order ones. I found this quote by a Google search. Formulas for the inverse of a polynomial, when they exist, often involve complicated combinations of roots of vario...

Re: possible bug +distort polynomial

I think Anthony may be correct. The polynomial may not actually be reversible at least in an easy way. However, @Anthony, does polynomial support EWA or are you defaulting to something else. With EWA, you would have had to have the derivatives of the inverse to compute the ellipse.
