Unintended resample while batch processing

[RM f/g]

If not a bug, then unexpected behaviour.

 

What I wanted to do: use batch process to change only the resolution of images, not their size in pixels.

 

What I did:

Opened image.

Recorded macro:

– Opened ‘Resize Document’ (from Menu > Document);

– set DPI: (from 72) to 300;

– unchecked ‘Resample’

– clicked ‘Resize’ button

Ended recording, saved macro.

 

When batch processing files using this macro, all processed files were resampled to the pixel size (at 300 ppi) of the original image, the image open when recording this macro.

This resampling happened without maintaining the aspect ratio. The original image was a square image, rectangular images were resampled to square images.

 

Ended changing the resolution of 215 images one by one.

Macros recorded in Affinity Photo 1.7 or later cannot change the resolution of an image without resampling, due to a bug introduced in 1.7 that hasn't been fixed yet.

Rather than recording your own, try using the macros below, which will work as they were recorded by John Rostron using 1.6:

Thanks, Walt. Where would we be without you – and John Rostron?

Downloaded John’s macros and tried them. They work as expected, but only if document units are set to pixels.

So I tried a new macro: set unit to pixels – run John’s macro – set units to millimeters.

Happy to see we can use a macro wihtin another macro.
