v7 -interpolate filter

[snibgo]

"-interpolate filter" is not valid in v7, either in "magick" or "magick convert". I assume this is an oversight or bug.

If it is intentional, then I suggest the documentation at http://www.imagemagick.org/script/comma ... nterpolate and http://www.imagemagick.org/script/porting.php should reflect this change.

The filter argument of the -interpolate option was removed because it was a slow and useless interpolation method. We updated the documentation to reflect this.

Thanks.

Is this a good idea to remove -interpolate? What happens when one uses -interpolate with -clut and other functions in IM 7, now? I have used it over 300 times in 26 scripts. What should I now expect will happen?

[snibgo]

The "filter" and "NearestNeighbor" options for "-interpolate" has been removed. Others remain. "Catrom" has been added.

Sorry I misunderstood. I thought you had meant that all of -interpolate was removed.

This is what I see

IM 6.9.4.2

convert -list interpolate

IM 7.0.1.4

What happened to NearestNeighbor in IM 7? Is Nearest the same as NearestNeighbor

[magick]

NearestNeighbor is aliased to Nearest. Use either one.
