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...

Re: Library producing 12MB MIFF images

add -verbose to your command line or -debug all and post the results here for the ImageMagick developers to see what might be wrong.

Re: Combine two psd files into one, keep filename

I do not think it is that simple. With PSD files, the first layer is the flattened layer from all the rest. Does the PSD files in this case have multiple layers?. Even if only one layer each, one would need to generate the flattened layer from the two images to add to the two individual layers. Can ...

Re: Library producing 12MB MIFF images

MIFF can only be viewed using ImageMagick display command. How did you try to open it? It has a header that can be viewed if you open the file in a text editor. The pixel data will be gibberish in the text editor, however.

Re: Library producing 12MB MIFF images

OK, you do have jpeg listed. Does this work?

Code: Select all

magick logo: logo.jpg
magick logo.jpg logo.gif
If so, then everything is fine with regard to your jpg delegate and I would suggest you review your code.

Re: Library producing 12MB MIFF images

What do you get from

Code: Select all

magick -version

or 

magick -list configure
does it list jpg or jpeg in the line for Delegates. If not, then you either have not installed libjpg where ImageMagick can find it or the llibjpg was installed faulty.
