Hello! Help. There is an object. I need to resize the image and get the pixels. I need information about the changed pixels. Is it possible without intermediate(TEMP) files? I do not know much English. That's what I want.

read image - IM
resize - IM
getpixels - IM
Not TempFile!

What do you mean "changed pixels" all pixels will be changes when you resize due to interpolation. Please always provide your IM version and platform when asking questions. Please explain in further detail you question. To get pixel values after you resize, just use the command line:
See https://imagemagick.org/Usage/files/#txt

Sorry, I do not know PerlMagick, only the command line.

Thanks for the answer. You understood correctly! Can this be done using the perl module?

Sorry, I do not know PerlMagick. Someone else will have to point you in the right direction.

With PerlMagick you can read an image, resize it, and get the pixels all in memory. See https://imagemagick.org/script/perl-magick.php for example PerlMagick scripts.
