I simplified the syntax here ;)
I do not understand what you simplified! Did my command work? If not then post your exact command.

Re: annotate parameter needs "magick convert" not only "magick" for some order

Please fix your syntax and test again. The following should work fine. If it does not, then let us know. magick -size 2480x3508 xc:white -annotate +120+120 "Hello World" emptypage.png However, you have not specified a font or pointsize. Thus you may not see the text you wrote very well. But it shoul...

Re: annotate parameter needs "magick convert" not only "magick" for some order

-size 2480x3508 needs an image to work on. Annotate does not create one. It just adds to an existing one. Move you xc:white right after -size 2480x3508. IM 7 is more picky about syntax order than IM 6. Use Magick only, not magick convert, even if it works. That may invoke IM 6 behavior if you add co...

Re: combining 2 images NOK windows last version but OK linux

-compose over is the default. But I always add it, especially when I have done other compose methods prior in the command line to reset it.

Sorry, see my changed solution -- add -colorspace sRGB after reading emptypage.png

Re: combining 2 images NOK windows last version but OK linux

Add -colorspace sRGB right after reading in emptypage.png in your second command. The white image is being treated as single channel grayscale, but should be 3 channel truecolor, since named colors even if black or white are supposed to be treated as color not grayscale. I confirm your issue on IM 7...

Re: Converting HEIC images with Display P3 color profile

The page at https://imagemagick.org/script/formats.php, says HEIC R Apple High efficiency Image Format HEIC requires the libheif delegate library. So ImageMagick can only read HEIC as far as I know. Check on your system using convert -list format and look at the line for HEIC assuming you have insta...

Re: combining 2 images NOK windows last version but OK linux

I am not sure I understand your question. Are you saying you get an error from

Code: Select all

convert -size 2480x3508 xc:white emptypage.png
What do you get from

Code: Select all

convert -version
What is your version of libpng?

You can see that from

Code: Select all

convert -list format
and look at the end of the line for PNG

Re: Converting HEIC images with Display P3 color profile

What is your ImageMagick version and platform? What was your exact command line? Can you provide your input image?

Re: scaling down to 120x90px Gray with less ringing

-filter Triangle -resize is just doing bilinear, so it is more "smooth" than lanczos.

Re: scaling down to 120x90px Gray with less ringing

See the discussion by Nicolas Robidoux who came up with the method you have found. See https://imagemagick.org/Usage/filter/nicolas/. He has other filter besides plain lanczos that you might try. The short answer is perhaps trade blurring for ringing by adjusting the resample blur amount with -defin...

Re: Lighten dark areas only?

If you are able to work in either Windows 10 Unix or Windows w/Cygwin, I have a bash unix shell script for which I tried to emulate Photoshop function of the same name. The results are similar but I do not claim it works perfectly to replicate Photoshop. Here I just adjust the shadow amount. Input: ...

Re: Lighten dark areas only?

Create a HALD image (in PNG output). Take it to your Photoshop and apply the same shadow highlight processing to it. Save as PNG. Bring it back to ImageMagick and apply that to your image using -hald-clut. See https://imagemagick.org/Usage/color_mods/#hald-clut

Re: Lighten dark areas only?

ImageMagick does not have a direct equivalent command to Photoshop shadows and highlights. So what user snibgo gave was one approach from what you asked originally. Did you try that? It seems to bring out the details in the hair as you asked. Also you said TIFF files, but the file you provided is JP...
