Description secretagent0016 2020-08-28 20:51:49 UTC
Created attachment 131252 [details]
Attachment contains images before and after the size is changed to 20%

SUMMARY

Applying zoom that is less than 100% (I used 20%) makes rough edges around objects, or (as can be seen in the attachment) can entirely remove some lines.


STEPS TO REPRODUCE
1. Load image (one is provided in the attachment)
2. Apply Position and Zoom and set size to 20%, and background white
3. Render project as Images Sequence (PNG)

OBSERVED RESULT

Circle in image (provided in the attachment) when reduced to 20% of its initial size has rough edges. The red line 1 pixel wide that was on the boundary of image disappeared on the bottom and right side, while on the top and left side red color didn't loose in intensity.


EXPECTED RESULT
