I went back to my old Mac system that has Photoshop PS (very old) and these commands work fine and the image look fine and the resulting resized images have clip paths. Using IM 126.96.36.199 Q16 and IM 188.8.131.52 Q16.
Code: Select all
convert test.pds -resize 50% test_r5_im6.psd
magick test.pds -resize 50% test_r5_im7.psd
The resulting psd files open fine in PS CS, look proper and do include clipping paths. I cannot say if the clip paths are correct or not. But I assume that since the images look fine with regard to the transparency, then the clip paths are correct.
Filling the paths with black matches the outline of the image with it transparent background. So I assume it is working fine.
If it does not work for you in your version of IM 7, then upgrade to the latest version and let us know if that works. What is your platform/OS? Please always provide your IM version and platform when posting questions.
