macOS Best way to Batch Resize Images twice?

[varsis]

Hi, Currently I am using an NSImage Technique which is okay for speed but can get very slow at some points in the program. I am looking for the best way I need to preserve the quality I have Interpolation set to high.

Any ideas I have Tried CIFilter. But that was Much slower than NSImage resizing.

I tried using A CIImage but the problem was I need to export to a File afterwards...

You could check out EpegWrapper.

You could check out EpegWrapper.

I use this already. It resizes the images on import, than on export it resizes them to a good quality thumb, and a Larger images about 800 wide.
