PNG to PDF convert on Linux command line

[kulpem]

I'm trying to convert a png image to a pdf file using Linux command line.

I have this image (example)



enter image description here

I'm trying to convert it to pdf using

convert (Imagemagick)

nothing help, I just get an empty white PDF file. Interesting enough the file weight as it contains everything

Of course, if I try to convert a regular square image all solutions work 100%

using version: ImageMagick 6.9.7-4 Q16 x86_64 20170114

"convert t.png x.pdf" works fine for me, with IM v6.9.9-50, and viewing x.pdf with Adobe Acrobat Reader DC 19.008
