Dear Affinity teram,

Would it be possible to include the option that copy/paste of images maintains the dpi of the pasted image independent of cm x cm dimension of source or destination of the image files?!

As an example, if I paste an image that is 300 dpi in resolution into a sheet that is set to 150 dpi then I expect the 300 dpi-image to be adjusted to the 150 dpi by doubling the cm dimensions (no loss of information). If I paste the same 300 dpi image into a 600 dpi paper then Affinity Photo should shrink the physical (printed) size maintaining the level of detail of the original dpi.

The current situation is opaque for the user because (1) the pasted image shrinks from 300 dpi to 150 dpi in order to maintain the cm x cm dimension (with lower resolution), but (2) at the same time somewhere information is preserved in the copied image hidden somewhere within afphoto files. If I next copy the low-resolution image to a 600 dpi template then the expected level of detail is returned (or interpolated, thus manipulated from the original) for the same cm x cm size but now at higher resolution. This is also visible in unexpected file sizes, for example in that a 100 dpi A4 page with a single image from a high-resolution source occupies 20 MB as afphoto but only 2 MB as (unzipped) TIFF.

I believe this poses a problem to workflows whenever images from different sources (e.g. microscope and plate scanner images and charts exported from ggplot2) with different dpi settings need to be combined into composite figures. The only workaround I found requires export to flattened TIFFs with mm (instead of dpi) as the dominant setting.

(Affinity Photo 2, version 2.5.7, MacOS and Windows)

Thank you and best wishes
