Re: ImageMagick7 runs much slower than version6
It is slower in part because IM 7 is built with HDRI by default. You can recompile without HDRI and you can recompile with Q8 in place of the default Q16. With IM 7, use magick in place of convert. The issue may have been fixed simply by using a more current version of libpng or if the IM 7 has lcms...

Re: Image looks different after removing transparent space and scaled
Did you try upgrading libpng? Did you try installing lcms? This is my command and result: convert b07s8dt2vc-large-front_image.png -resize 3500x3500^ b07s8dt2vc-large-front_image_resize.png http://www.fmwconcepts.com/misc_tests/b07s8dt2vc-large-front_image_resize.png If this looks correct, then try ...

Re: Image looks different after removing transparent space and scaled
Your Imagemagick is ancient by version number, though currently patched supposedly on 9/29/2019. So just a couple of weeks ago. But Linux distributions often only patch for security. So it is possible there is a bug or a missing update. But I would start with upgrading your libpng, if you can. The v...

Re: How to add to image a text with some transparency; optionally with some noise?
As snibgo has indicated, use a partially transparent color. You can use hex or rgb definitions. See https://imagemagick.org/script/color.php

Re: implode region in IM 7
Thanks. Is there a workaround other than compositing with a mask image?

Re: Why am I getting colors for 4 channels from a png image?
No they can have 4 if you count the alpha channel. But you have 12 hex values. So that means you have a 3 channel 16 bit image. Your imagemagick is likely Q16 (default) which means 16-bit compile. So you can get that kind of value for colors. See https://imagemagick.org/script/color.php

Re: Image looks different after removing transparent space and scaled
What scaling? Your original post command line has no scaling! What was your exact command? Your PNG version libpng 1.6.28 is a bit old. You might consider upgrading.

Your Imagemagick is ancient, though currently patched. But Linux distributions often only patch for security. So it is possible there is a bug. I saw no difference.
Try
convert -list format
and see what version you have for PNG.
